The unit can raise the temperature of geothermal water from 30-50°C to 70-80°C. It is compatible with various heating systems and can replace coal-fired boilers for geothermal heating in cold regions while retaining the original radiator systems. The discharge temperature of geothermal tail water is as low as 20°C, better than the national standard of below 30°C, with heating COP ≥ 3.0.

Geothermal energy combined with high-temperature heat pumps replaces coal-fired boilers, featuring environmental and economic advantages. It eliminates pollution from flue gas and waste residues of coal combustion, and cuts costs for fuel transportation, storage, dust removal and residue treatment. It supports winter heating, summer cooling and heat recovery. One unit replaces both air conditioner and boiler, greatly improving equipment utilization rate.

Equipped with specially designed compressors. The operating pressure is below 26 bar and discharge temperature is lower than 120°C under high-temperature conditions, ensuring stable and efficient operation. The mixed working fluid is safe and eco-friendly with low toxicity, non-flammability and non-corrosiveness. It delivers strong cooling capacity and good oil solubility, and the temperature fluctuation is less than 1.5°C under high-temperature working conditions.

Adopts user-friendly microcomputer control system with high automation level for easy operation and fewer operators. It has an attractive appearance and saves installation space.
