HU 1i

High-frequency converter
1 kW // 1.0 - 3.0 MHz

Our HU 1i high-frequency generator ensures the lowest possible heat penetration depth thanks to its frequency range of up to 3.0 MHz.

It allows for optimal reproduction of all parameters and can be easily integrated into all production processes. Microprocessor-controlled, it heats particularly thin materials for work processes such as coating, stress relieving, or soldering.

The HU 1i is ideally suited for workpieces in the sub-millimeter range, such as medical needles or stent implants, or for the production of battery foils.

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
