Product Detail

Commercial Air Energy Water Heater-Circular

Performance characteristics:
1. Three innovative variable flow technologies: W / A / R (Water, Air, Refrigerant) are used to overcome the weaknesses of circulating products, improve the equipment's low thermal efficiency in cold conditions, and solve high temperature conditions The two major problems of easy overload operation of the lower compressor ensure the water temperature is constant and durable;
2. The application of W / A / R variable flow technology makes the unit lower in noise and vibration during operation;
3. The new SAC refrigerant circuit technology effectively solves the precise distribution of energy supply in part load and achieves the lowest system operating cost;
4. Fast defrosting technology makes the unit run well in low temperature and humid environment.
