90° Very High Temperature Water Source Heat Pumps

Leomon’s water-source heat pumps are premium solutions for district heating networks and industrial process heating (with temperatures reaching up to 90°C).

Applications

* Industrial process heating

* District heating networks

* Inlet temperatures up to 29°C

Design

* Ultra-low GWP (Global Warming Potential) R1234ze refrigerant

* Screw compressors designed for continuous, heavy-duty, high-temperature operation

* Cooling system with internal circuitry

* Robust shell-and-tube heat exchangers

Output Range

* Heating capacity ranging from 410 kW to 735 kW

Our high-temperature heat pumps are suitable for domestic hot water and space heating applications. They also serve specialized industries—such as food processing, electric forging, spray coating, packaging and printing, chemicals, and slaughtering—that require hot water at temperatures exceeding 55°C.

Advantages

1. Compressors

Our large-scale heat pumps utilize US-made Copeland scroll compressors, while smaller models use compressors; both are specifically designed for heat pump applications and offer high operational efficiency.

2. Electrical Control System

The control system enables easy management of circulation pumps, water make-up, water supply, auxiliary electric heating, and PID-based automatic defrosting. Users can configure parameters to meet specific project requirements and achieve full system automation.

3. Shell-and-Tube Heat Exchanger

The heat pumps feature high-efficiency shell-and-tube heat exchangers with a heat transfer area 3.7 times that of bare-tube designs. Their unique configuration and compact spiral structure ensure optimal refrigerant heat exchange.

4. Electronic Expansion Valve

We utilize Sanhua expansion valves combined with our proprietary control system to implement a specialized electronic expansion controller. This system employs digital technology to adjust refrigerant flow based on temperature factors, ensuring optimal flow rates and achieving a higher Coefficient of Performance (COP).
