HU 5i

High-frequency generator
5 kW // 0.1 – 1.0 MHz

Our HU 5i high-frequency generator ensures a moderate to low heat penetration depth through frequency ranges up to 1.0 MHz.

It allows for optimal reproduction of all heating parameters and can be easily integrated into any production process thanks to modern interface options. Microprocessor-controlled, it precisely heats thin materials for processes such as soldering, melting, sealing, or hardening.

With the HU 5i, you bring more energy efficiency to your production, reduce waste, and accelerate your output.

With a wide range of optional interfaces, control systems, and sensors, our new i-generation devices adapt to your exact needs and integrate seamlessly into your process.

The HU 5i is the full-fledged successor to the HU 5000+ and replaces it in our portfolio. Do not hesitate to contact us with any questions or service needs for your legacy device.

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
