The LEOMON FKH-90II/TGW is a high-output industrial steam heat pump delivering 160kg/h of 150°C saturated steam. With a heating capacity of 90kW and power draw of 56kW, this unit is designed for large-scale continuous process heating. Its enlarged evaporator and dual-fan design ensure efficient heat absorption even at low ambient temperatures. Dimensions: 3260×1230×2400 mm, weight 1430 kg. Steam connection DN40, water inlet DN20. Maximum operating current 150A. Noise ≤80 dB(A). Built for long-term reliability, this model serves as a direct replacement for medium-sized electric or fossil-fuel boilers, cutting energy costs and emissions.

1. High Output Meets Demanding Processes
160kg/h of 150°C steam supports heavy-duty applications like large autoclaves, continuous drying lines, and multiple process stations simultaneously. The unit maintains stable pressure and temperature regardless of load variations within its capacity.
2. Superior Energy Efficiency
The FKH-90II/TGW reduces electrical consumption by approximately 38% compared to an electric boiler. When replacing gas or oil boilers with electric drive (via grid power), the operating cost savings are even greater if electricity prices are competitive. Additionally, the unit recovers heat from ambient air, making it a renewable-based solution.
3. Advanced Defrosting for Low-Temperature Performance
The intelligent defrost cycle uses temperature and time criteria to minimize frosting on the evaporator. Defrosting occurs only when necessary, reducing energy loss and maintaining high output even at 15°C ambient.
4. Built-in Redundancy & Safety
Dual refrigeration circuits (in larger models like this) ensure that if one circuit fails, the other can operate at reduced capacity, preventing a complete shutdown. Multiple protection devices safeguard the compressor and electrical components.

Large Canneries & Sauce Production
Delivers 160kg/h of 150°C steam for retort sterilization and continuous cooking kettles. The high output supports multi-line operations, eliminating steam bottlenecks.
Industrial Laundries
Powers large ironers, tunnel washers, and steam presses. The unit’s energy efficiency (COP 1.61) significantly lowers electricity costs compared to electric boilers.
Building Materials
Provides stable high-temperature steam for autoclave curing of aerated concrete blocks. The unit can be paired with a steam accumulator to handle peak loads.
Installation requires 4–5 days, including a dedicated electrical cabinet and a soft water tank with deaerator. The unit’s dimensions (3260×1230×2400 mm) need a clearance of at least 1.5 m on all sides for service access. Daily maintenance: check the water conductivity, perform automatic blowdown, and verify the steam pressure regulator. Monthly tasks: inspect the titanium heat exchanger for scaling, clean the evaporator coil, and test safety devices. Annual professional service includes refrigerant charge check, compressor vibration analysis, and control system firmware update.
Q1: How long does it take to reach 150°C from a cold start?
A: Approximately 15–20 minutes, depending on water volume in the steam generator. The unit can be kept in standby mode for faster response.
Q2: Can multiple units be connected in parallel?
A: Yes. Up to 8 units can be cascaded using a master controller, providing steam up to 1,280 kg/h. This offers flexibility and redundancy.
Q3: What is the maximum water inlet temperature?
A:Recommended feed water temperature is 10–30°C. Higher inlet temperatures (e.g., returning condensate at 70°C) can improve efficiency but must be evaluated by our engineers.
Q4: Does the unit need a permit or special inspection?
A: Unlike steam boilers, this heat pump does not fall under pressure vessel regulations in many jurisdictions because the steam is generated within a tube-in-tube or plate heat exchanger that is not a fired pressure vessel. However, local codes vary; please check with your authority.
