150℃ Heavy-Duty Steam Heat Pump 65kW FKH-65II/TGW Industrial Steam Generation

The LEOMON FKH-65II/TGW is a heavy-duty air-source steam heat pump designed for continuous industrial steam generation at 150°C with a nominal output of 100kg/h. With a heating capacity of 65kW (power consumption 40.5kW), this model delivers substantial energy savings while providing robust performance for factories with high steam demand. Its dimensions (3260×1030×2400 mm) and weight (1180 kg) reflect its industrial-grade construction. The DN40 steam connection and DN20 water inlet support high flow rates. Designed for 24/7 operation, it maintains reliable performance even at low ambient temperatures down to 15°C. Noise level ≤75 dB(A) makes it acceptable for most industrial zones.

Core Advantages of the FKH-65II/TGW Heat Pump

1. Designed for Continuous Duty

The FKH-65II/TGW uses an industrial scroll compressor and a large evaporator designed for extended runtimes. With smart defrosting cycles, it maintains output even in humid or low-temperature conditions. Mean time between failures (MTBF) exceeds 30,000 hours.

2. Massive Energy Savings

Compared to an electric boiler (COP = 1.0), this heat pump achieves a COP of 1.6 (65/40.5 = 1.6), reducing electrical consumption by ~38%. While the lift to 150°C is high, the savings are significant over the lifetime. For customers currently using diesel or gas boilers, the savings are even greater (up to 50–70% depending on fuel price).

3. Integrated Safety & Protection

The unit includes high-pressure cutout, low-pressure protection, compressor overcurrent protection, anti-freeze protection, and a manual reset high-temperature thermostat. Compliant with CE and international industrial safety standards.

4. Flexible Installation Options

Despite its size, the unit can be installed outdoors on a concrete pad or steel frame. The anti-corrosion casing (similar to 304 stainless steel) resists rust. Multiple units can be cascaded for higher total steam output.

Ideal Application Scenarios

Dairy & Beverage Plants

Perfect for pasteurization, UHT preheating, and CIP (clean-in-place) steam heating. The 100kg/h steam flow meets the demand of medium-sized milk processing lines.

Rubber Vulcanization

Provides 150°C saturated steam for curing presses. The heavy-duty compressor and defrost system ensure reliable operation even in humid factory environments.

Wood Drying Kilns

Ideal for preheating and conditioning wood veneers or lumber. The unit’s continuous output reduces drying time compared to electric heating.

Installation & Maintenance

The FKH-65II/TGW requires a reinforced concrete pad (min. 3m×2m) due to its 1180 kg weight. Installation takes 3–4 days, including piping, electrical, and integration with existing steam headers. The unit includes an automatic blowdown valve to simplify daily operation. Weekly maintenance: check safety valves, drain condensate from the steam separator, and record operating pressures. Every 3 months, inspect the evaporator fins and clean with compressed air. Annual professional service recommended. A remote monitoring module (optional) allows predictive maintenance alerts, reducing unplanned downtime.

FAQ About Energy-Efficient Steam Heat Pump FKH-65II/TGW

Q1: What is the actual steam pressure?
A: At 150°C saturated steam, the pressure is approximately 4.8 bar absolute (3.8 bar gauge). The unit can be adjusted to lower temperatures (e.g., 140°C) for reduced pressure if needed.

Q2: Can this unit replace a 100kg/h electric boiler?
A: Yes, directly. It will use roughly 60% less electricity for the same heat output. However, initial capital cost is higher. Payback is typically 1.5–2.5 years depending on electricity rates and run hours.

Q3: What is the noise level in practice?
A：75 dB(A) measured at 1m distance. This is similar to a large air conditioner. In an industrial setting, it is not disruptive.

Q4: Does the unit require a water softener?
A: Strongly recommended. Scale will degrade performance over time. We can supply an optional water softening system.
