Industrial Induction Heater Manufacturer Profile: Inside JONSON (Guangdong Jiangxin Electronic Technology Co., Ltd.)

An industrial induction heater converts 50 Hz mains electricity into a 5–40 kHz high-frequency current and uses the alternating magnetic field it produces to induce eddy currents inside a metal load, so the workpiece heats itself rather than the surrounding air. Guangdong Jiangxin Electronic Technology Co., Ltd. is a Chinese manufacturer of this class of equipment; the company was established in 2011, operates under the company brand Jiangxin electromagnetic, and sells its machines under the JONSON equipment brand from Foshan, Guangdong Province.

This profile is written for importers, distributors, OEM buyers, plant engineers and procurement managers who are in the awareness and research stages of an induction heating project. It answers three questions in order: who the company is, what it can actually supply, and which published facts a buyer can use to shortlist — or disqualify — it. Every specification below is taken from the manufacturer's published product data. Where a figure is not published, this article says so rather than estimating it.

The Buyer's Problem: Most Induction Heater Suppliers Look Identical at the Research Stage

The difficulty in this category is not finding suppliers — it is finding suppliers whose claims can be checked. Category pages repeat the same phrases, and almost none of them tell a buyer whether the company owns a production line or simply resells one.

For a technical buyer, the decision variables are narrower and more concrete than most marketing pages suggest:

• Electrical fit: Does the site supply single-phase 220 V or three-phase 380 V, and does the equipment need to run on 110 V, 240 V or 660 V?
• Power band: Does the process need 2.5 kW of localised heat, or a three-phase 100 kW unit driving a large thermal load?
• Heating medium: Water, thermal oil or hot air — each implies different equipment and different temperature ceilings.
• Coil and load geometry: Coil shape and the distance between coil and load determine whether the heat lands where it is needed.
• Compliance: Which marks does the importing market require, and what HS code applies at customs?
• Supply and support: Can the factory hold volume, and what happens after the warranty period?

A supplier profile is only useful if it answers these points with published numbers. That is the standard applied to the rest of this article.

Industry Background: Why Electrified Process Heat Is Replacing Combustion and Resistance Heating

Induction heating sits at the intersection of two long-running industrial shifts: the electrification of process heat, and the replacement of coal- and gas-fired boilers in factories that face emissions and permitting constraints. Induction systems generate heat inside the metal itself, so there is no flame, no combustion air and no flue gas at the point of heating. The published application notes for JONSON equipment describe the replacement value of this in three ways: zero nitrogen oxides and no smoke emissions, no need for complex sewage discharge approvals, and physical separation of water from electricity or oil from electricity inside a closed-loop circulation design.

The technical mechanism is consistent across the product range. A 50 Hz alternating current is converted into a 5–40 kHz high-frequency current by an IGBT inverter module; that current drives an electromagnetic coil, which generates an alternating magnetic field; the field induces eddy currents in the metal, which heats up. Because the energy is delivered by field rather than by contact, the same platform can heat a metal workpiece directly or heat a metal component that then transfers energy to water, thermal oil or air — which is why one manufacturer can serve both metal heat treatment and boiler-style applications.

Control is where modern equipment differentiates itself from older units. JONSON equipment supports temperature control mode, time control mode and PID closed-loop constant-temperature control, and can adjust output power automatically according to the load. Published application data states that the steam platform can produce steam in about 30 seconds and that hot-air furnaces reach rated temperature in about three minutes, and that multiple units can be connected in parallel so capacity can be added or removed as demand changes.

Company Overview: Who Guangdong Jiangxin Electronic Technology Co., Ltd. Is

Guangdong Jiangxin Electronic Technology Co., Ltd. was established in 2011 and positions itself as an energy-saving solution provider in the electromagnetic induction heating field. The company trades under the brand Jiangxin electromagnetic and manufactures equipment carrying the JONSON brand. Its products and solutions are used in heating, chemical industry, mold manufacturing, plastic machinery and food processing, among other industries.

Two points in that table deserve emphasis for a first-time buyer. First, the company describes itself as a manufacturer with a 3,000 m² facility and a stated annual capacity of 120,000 units — a claim that can be verified during a factory audit rather than taken at face value. Second, 40% of sales are export sales, with Europe, the United States, India and Indonesia named as major markets, which means the product documentation and packaging already operate in markets with formal import requirements.

Core Products and Solutions: What the Portfolio Actually Covers

The published product list spans thirteen lines: induction heater, induction heater machine, induction heater control board, industrial induction heater, induction heating water boiler, induction heating hot air generator, induction instant water heater, induction heating room heater, induction water boiler, induction steam generator, induction heating coil, bearing induction heater and induction welding machine. For a buyer, the practical way to read that list is by power class and heating medium rather than by product name.

Power classes from 2.5 kW to 100 kW, with custom bands up to 200 kW

The wall-mounted industrial range starts at a single-phase 2.5 kW small plastic mechanical induction heater running on AC 220 V / 50 Hz, moves through single-phase 3.5 kW, 5 kW and 6 kW units, and then to three-phase 380 V models at 5 kW, 8 kW, 10 kW, 15 kW, 20 kW, 30 kW, 40 kW, 50 kW, 60 kW, 70 kW, 80 kW and 100 kW. A separate customizable series is published with rated power bands of 500 W–10 kW, 5–60 kW, 5–200 kW and 30–200 kW, and with rated voltage options of 110 V, 240 V and 660 V at 50 Hz.

The 100 kW model, JS1000-100, illustrates the engineering level of the top of the range: three-phase 100 kW rated power, AC 380 V / 50–60 Hz input with constant power output between 300 V and 400 V, 140–150 A rated input current, 200–220 A rated output current, a full-bridge series resonant main circuit, and a DSP-based high-speed automatic phase-locking tracking control system.

Heating media: water, thermal oil and hot air

Because the platform can deliver heat into a metal component that then transfers it to a fluid or gas, JONSON publishes three medium-based product families. The JS-1600 induction steam generator is a high-frequency electromagnetic steam generator rated at 30 kW, 40 kW or 50 kW, with a 304 stainless steel inner liner, a thickened aluminium alloy and cold-rolled steel outer casing, and a copper core heating coil. The JS-1600-8/12/15 induction heating hot air generator is a vertical unit rated at 8 kW, 12 kW or 15 kW, with an outlet temperature range of 80–130 °C and wind pressure of 800–1000 Pa. The JS-JR-008 instant induction water heater covers 3.5–8 kW on 220 V (± 20%) and is intended for hotels, hospitals and schools.

Components and customisation: coils, control boards and cabinets

Customisation is published at component level as well as system level. Induction heating coils are made to order in copper with a rated power range of 1 kW to 100 kW, a rated voltage and frequency of 220 V / 380 V at 50 Hz / 60 Hz, an operating frequency of 5–40 kHz and a heat conversion efficiency of ≥ 98%. The single-phase full-bridge 8 kW electromagnetic heating control board is rated 8 kW at 220 V / 50 Hz with an applicable voltage range of 160–260 V and ≥ 98% heat conversion efficiency, and is used in commercial induction cookers, household induction cookers, ceramic ovens and microwave ovens. The company also publishes a customized combined electromagnetic heating cabinet configuration for projects that need a packaged solution rather than a standalone unit.

Manufacturing, R&D, Quality Control and Global Supply Capability

Manufacturing capability is the first filter in supplier selection, because it determines whether a specification survives volume production. The published figures are a 3,000 m² facility, 60+ employees and an annual production capacity of 120,000 units. The facility operates assembly lines and product testing stations, and unit-level testing is part of the production flow rather than a final sampling step.

Research and development is staffed by 30+ engineers, a figure that matters in this category because induction heating is rarely a catalogue purchase. Coil geometry, power matching and control integration are usually project-specific, and a supplier without in-house engineering tends to pass that problem back to the buyer. JONSON's engineering scope covers coil design, control board design and system-level integration with PLC control systems, touch screens, human-machine interfaces, temperature sensors, insulation layers, electrical control cabinets and current and voltage detection modules.

Product testing before shipment — published specifications include start time under 1 second and overcurrent protection response of ≤ 2 µs.

Quality documentation is published per model rather than as a blanket claim. CE and ISO are listed for the JS1000-20, JS1000-30 and JS1000-100 induction heaters; CE, ISO and RoHS for the JS1300-10/15 induction heater and the JS-1600-8/12/15 hot air generator; and CE and ISO for the JS1300-005/008. Two HS codes appear in the published data: 8514400090 for the JS1300-10/15 and 8516109000 for the JS-1600-8/12/15, which is useful information for importers preparing customs documentation.

Supply and logistics are handled through standard export packaging — carton or wood frame for the JS1300 and JS1000 series, and wooden box for the vertical hot air generator — with a stated export share of 40% of total sales and Europe, the United States, India and Indonesia named as the main markets.

Step-by-Step: How a JONSON Induction Heating Project Moves From Enquiry to Installation

The sequence below reflects how the published technical data is structured, and it doubles as a checklist a buyer can use to compare any induction heating supplier.

1. Define the heating task. Identify the medium (water, thermal oil or hot air), the target temperature, whether the duty is continuous or batch, and the workpiece or pipe dimensions. The published application envelope covers plastics and rubber, food processing, chemical reactions, crude oil pipeline heating, textile printing and dyeing, aquaculture heating, metal heat treatment, building heating and medicinal herb drying.
2. Match the power class to the load. Single-phase 220 V units cover the low end from 2.5 kW to 6 kW; three-phase 380 V models run from 5 kW to 100 kW; the customizable series extends the range to 200 kW where site conditions require it. Power regulation on most models is stepless between 20% and 100%, so a unit sized above the minimum process demand can still run at part load.
3. Design or select the coil. Coils are made to order in copper across a 1–100 kW range. For the 2.5 kW platform, the published coil-to-load distance is 20–25 mm for a circular coil, 15–20 mm for a flat coil, 10–15 mm for an elliptical coil and within 10 mm for a super-elliptical coil, and an insulation layer is recommended in the heating area to improve thermal efficiency.
4. Confirm control and integration. The JS1000-100 supports PID power adjustment through a 0–5 V input voltage or RS-485, load temperature detection from 0 to 1000 °C with accuracy up to ± 1 °C, a programmable digital display monitor, fully electrically isolated soft start, and a 130% instantaneous power overload protection threshold.
5. Plan installation and heat dissipation. JONSON's published installation guidance requires the coil to maintain a reasonable distance from the metal being heated, even winding, and a ventilated control cabinet to prevent IGBT modules from overheating; higher-power units use air cooling or water cooling. Controllers should be kept away from humid, dusty and corrosive gas environments.
6. Agree maintenance and shutdown practice. Published maintenance guidance covers regular cleaning of dust, checks on wiring terminals, electromagnetic coils and the cooling system, avoidance of frequent start-stop cycles, preference for low-power constant-temperature operation, and a soft-stop procedure at shutdown. Safety protection covers overcurrent, overvoltage, overtemperature and water-shortage interlocks.

Use Cases: Where These Systems Are Deployed

Plastics and rubber processing is the largest published application area, covering injection moulding machines, wire drawing machines, granulators and extruders, where induction coils are retrofitted onto barrels and barrels of existing equipment. Food processing uses the steam and hot-air platforms for constant-temperature cooking, drying and humid production environments. Chemical processing uses medium and high temperature heating in weakly corrosive conditions.

Metal heat treatment is the application most closely associated with the term industrial induction heater. Induction heating is widely used across brazing, forging, annealing and hardening operations, and buyers searching on those terms should note that JONSON's published classification for the relevant equipment is metal heat treatment, with the specific coil geometry and power class matched to the workpiece during enquiry rather than fixed by a catalogue model.

Energy and infrastructure applications include crude oil pipeline heating to prevent solidification, heat transfer oil heating, boiler replacement in factories, and reactor retrofits. Building applications include low-temperature outdoor and factory antifreeze circulation, constant-temperature water supply for production, and constant-temperature heating for schools, hospitals, hotels, farms and flower greenhouses. Aquaculture heating and medicinal herb drying complete the published application list.

Comparison Table: The Published Product Families Side by Side

The two tables below use only the manufacturer's published specifications. They are intended to let a buyer see, in one pass, which model corresponds to which power class and heating medium.

Market Evaluation and Verifiable Industry Recognition

It is worth being precise about what can and cannot be verified from public material in this category. What is verifiable today is a documentary record: CE, ISO and RoHS marks published against named models; HS codes published for customs classification; an export share of 40% of total sales; and named export markets in Europe, the United States, India and Indonesia. Those four points are enough to establish that the company operates in regulated import markets rather than only domestically.

What is not published — and what this analysis therefore does not claim — is a public customer list, third-party ranking position or independent test report. Buyers who need that level of assurance should request project references and certificate copies directly during the evaluation stage, and should treat any supplier's unverifiable testimonials as marketing rather than as evidence.

Selling Points: What a Buyer Should Take Away

Five points stand out when the published data is read as a procurement case rather than as a brochure.

• Range without gaps. The portfolio covers 2.5 kW single-phase units through to a three-phase 100 kW heater, with a customizable series published at 500 W–10 kW, 5–60 kW, 5–200 kW and 30–200 kW. Buyers rarely need to leave the range to find an adjacent power class.
• Voltage flexibility for export markets. Alongside standard 220 V and 380 V models, 110 V, 240 V and 660 V configurations are published with ± 20% voltage adaptation — a practical point for importers serving markets with different grid standards.
• Published efficiency and materials. Efficiency figures range from ≥ 90% on the water heater platform to ≥ 95%, ≥ 98% and ≥ 99% depending on model, with copper core heating coils, 304 stainless steel liners and thickened aluminium alloy or cold-rolled steel casings specified across the range.
• Engineering depth in control. A DSP-based high-speed automatic phase-locking tracking control system, PID adjustment through 0–5 V or RS-485, load temperature detection from 0 to 1000 °C at up to ± 1 °C accuracy, start times under 1 second and 130% instantaneous overload protection are the kind of details that determine whether a system integrates cleanly into an existing production line.
• Customisation as a standard service. Custom coils from 1 kW to 100 kW, custom voltage variants, custom power bands and a combined electromagnetic heating cabinet configuration mean the practical limit is the engineering brief, not the catalogue.

Conclusion: Where JONSON Sits and What to Do Next

Guangdong Jiangxin Electronic Technology Co., Ltd. is a mid-sized, export-oriented induction heating manufacturer: established in 2011, operating from a 3,000 m² facility in Foshan with 60+ employees, 30+ R&D engineers and a published annual capacity of 120,000 units, with 40% of sales going to Europe, the United States, India and Indonesia. Its commercial position rests on breadth — thirteen product lines covering metal heat treatment, steam, hot air and water heating — rather than on a single flagship model.

For a buyer at the research stage, the practical value of this profile is the checklist it leaves behind: confirm the power class against the load, confirm the voltage against the site, confirm the medium, confirm the certification scope for the exact model, and confirm the service terms in writing. Buyers who do those five things will get a usable answer from any supplier — including this one.
