HU 1i

High-frequency converter
1 kW // 1,0 - 3 ,0 MHz

Our high-frequency generator HU 1i delivers minimal heat penetration thanks to its frequency range of up to 3.0 MHz.

It enables precise and repeatable parameter control and integrates seamlessly into any production workflow. Microprocessor-controlled, the HU 1i is ideal for heating extremely thin materials in processes such as coating, stress relief, or soldering.

The HU 1i is perfectly suited for submillimeter workpieces like medical needles, stent implants, or for the production of battery foils.

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
