Low Temperature Optimized Heat Pumps

Low temperature optimized heat pumps are specially designed to meet the heating and cooling needs of households in cold areas and including domestic hot water.

High-efficiency heat pumps can effectively provide reliable and efficient heat at temperatures as low as -25°C. When the temperature is more than 20 degrees Celsius, such a system can provide heat with an efficiency of 500%, and the efficiency at -25°C may be close to 150% to 200%.

The heat pump adopts the most advanced low-temperature enhanced steam jet compressor technology. This enables the heat pump to effectively produce water temperatures as high as 60 DC in the cold winter.

Low Temperature Optimized Heat Pumps Feature:

1).EVI compressor is specially designed for high water temperature

2). Intelligent controller, fast microprocessor adjustment

3). Water exchanger with high-efficiency pipes in the shell heat exchanger

4). Multiple protections to protect the compressor and heat exchanger

5). Indoor and outdoor split or integrated design, easy to install

6). Including automatic defrost function (with reverse valve inside)

7). It can be used for floor heating, fan coils, water heaters and modern radiators

8). The perfect defrosting system allows the unit to work at an ambient temperature of -20 degrees Celsius

9). R417a or R407c refrigerant, environmental protection-green energy, no CO2 emissions

10). Safety: Water and electricity are completely isolated, and there are no potential hazards such as flammable, gas poisoning, explosion, fire, electric shock, etc. related to other heating systems

Warranty:

1). Passed CE and RoHS certification

2). Service life is about 20 years

3). 2 years warranty, buy with confidence

Heat Pump Components:

1. Silver welding

Silver welding technology makes the unit system more reliable; it is likely that it will avoid refrigerant leakage

2. Intelligent control

Unit adopts intelligent control system: microprocessor-based digital controller, LCD display

3. Efficient and environmentally friendly refrigerant, does not destroy the ozone layer

4. Hot gas defrost

Lanwei defrosting system adopts "SAGINOMAMIYA" four-way valve. It can defrost itself intelligently and efficiently

5. EEV technology

The electronic expansion valve technology adopted by Leomon is a very unique and advanced technology. Through the intelligent control of refrigerant flow, the use of electronic expansion valve (EEV) has many advantages to the system.

1. EEV adds heating output and COP

2. EEV improves overall operational reliability

3. EEV extends the service life of the compressor

6. DC inverter, energy saving

The DC inverter technology enables the unit to obtain higher efficiency and can save more than 30% of energy consumption per year.

7. The famous-brand plate heat exchanger ensures the high efficiency and reliability of the entire heat pump system
