HU 2i

High-frequency converter
2 kW // 0.25–1.0 MHz

Optimized for shallow heat penetration, our high-frequency generator HU 2i offers frequency ranges up to 1.0 MHz.

With it, all parameters can be reproduced optimally, while — thanks to modern interface options — it can be easily integrated into any production workflow. Microprocessor-controlled, it heats especially thin materials for processes such as soldering, melting, or hardening.

Bring more energy efficiency to your production, reduce scrap, and accelerate your throughput.

With a wide range of optional interfaces, control systems and sensors, the HU 2i adapts to your exact needs and integrates seamlessly into your processes.

The HU 2i is the full-fledged successor to the HU 2000+ and replaces it in our portfolio. Don’t hesitate to contact us with any questions or service needs regarding the predecessor model.

Overview products

Since 1950, Himmelwerk has shipped more than 19,000 high and medium frequency converters worldwide.
By how much can you reduce your CO₂ emissions per year? Let’s have a look.

Assumption 1: 25% of your converters are still operational.

Assumption 2: They have an average output of 6 kW and thus a power consumption of 7 kW.

Assumption 3: These generators are operational 8 hrs per day and 5 days per week.

Assumption 4: Inductive heating uses up to 40% less energy than conventional methods. Let’s assume 30%.

With these assumptions, our calculation would look like this: Daily energy consumption: 8 hrs x 7 kW = 56 kW

Energy savings per day: 56 kWh / 0.7 = 80 kWh; 80 – 56 = 24 kWh

Total energy savings per day: 24 kWh x 4,750 converters = 114,000 kWh

Total energy savings per year: 220 working days x 114,000 kWh = 25,080,000 kWh

Conversion factor kWh/CO₂: 1 kWh is equivalent to approx. 0.485 kg of CO₂ (source: German Federal Environmental Agency, Climate Change 15/2022)

CO₂ reduction per year: 25,080,000 kWh x 0.485 kg = 12,163,800 kg
