Hot and cold air heater

◎ Uses 60°C low‑temperature hot water to produce 7°C chilled water, with the supply and return pipes on the same side—bottom inlet, top outlet. ◎ Employs a copper‑tube, aluminum‑fin heat exchanger; requires high‑quality water and must be equipped with water‑treatment equipment. ◎ The inlet and outlet pipes are connected via threaded joints; during summer cooling, condensate will form and must be drained through a dedicated pipe.
