The Benchmark in Clean Heating
No fuel, no emissions. Just reliable, precision-controlled thermal power.
100% Electric & Fuel-Free
Operates entirely on electricity without the need for gas or diesel. This eliminates open flames and toxic exhaust, providing pure, unpolluted hot air essential for cleanrooms and food drying.
Premium Craftsmanship
Built with a double-layered, heavily insulated steel casing. Our precision welding and thermal barriers ensure minimal heat loss while keeping the external chassis safe to the touch.
24/7 Unmatched Reliability
Driven by high-performance stainless steel finned tubes and intelligent PID control. Designed to handle continuous, high-load thermal loops without failure.
The Re-flow Thermal Loop
Traditional heaters waste massive amounts of energy by venting hot exhaust. The HAM-R Series features specialized high-temperature internal components that allow it to safely suck in return-air as hot as 230℃ (446℉).
- Significantly reduces electricity consumption by reheating already warm air.
- Accelerates the time needed to reach the target process temperature (up to 350℃).
- Equipped with dual thermal overload protection for absolute safety.

Technical FAQ: Re-flow Series
What is the main advantage of the HAM-R Re-flow series?
The HAM-R series is explicitly designed for thermal recycling. Unlike standard heaters that draw in cold ambient air, the HAM-R is built with specialized heat-resistant internal components that allow it to safely intake pre-heated exhaust air up to 230°C (446°F) from closed-loop ovens, drastically reducing energy waste.
How much electricity can the Re-flow system save?
By reheating return air instead of heating cold room air from scratch, the required heating power (kW) drops significantly. Depending on the insulation of your drying tunnel, the HAM-R Re-flow system can reduce overall electricity consumption by 30% to 50% compared to standard open-loop heating systems.
What capacities are available for the HAM-R?
The Re-flow series scales from 3 kW for compact testing ovens up to 60 kW for massive continuous industrial drying lines, delivering airflows up to 25 m³/min. Our engineering team can help you calculate the exact kW size needed based on your specific thermal loop design.
