R134A Screw Type Water Or Geothermal Source Heat Pumps
Product Performance:
A. Optimized design
Fully follow international standards, combined with Chinese design, and actual national conditions.
The technical idea of "large temperature difference, small flow" saves resources to the maximum for users.
The system adopts independent modules and has high reliability.
Computer-aided optimal design to ensure that the unit is in good condition under any working conditions.
B. Sophisticated options
Imported compressors and refrigeration components to ensure efficient and reliable operation of the unit.
The high-quality controller combined with the special control program of the water source heat pump is more convenient in terms of intelligence and networking.
The high-efficiency heat exchanger is jointly developed with professional supporting manufacturers.
C. Simple operation and reliable operation
Fully computer-controlled and equipped with a backup manual operating system.
Perfect computer control and multiple protections make the whole machine safe and reliable.
D. Flexible and convenient parameter setting
More than 80 variable built-in parameter settings can adjust the working status of the unit at any time.
Power-off memory protection can maintain the continuity of the running state.
