The manual contains information about purpose, technical details, operating principle, design, and installation of the WKH unit and all its modifications.
PURPOSE Device WKH with water as heat carrier and round or rectangular connection to the air duct is designed for heating of air in the air- conditioning, ventilation and hot-air heating systems and in drying units and warm air curtains.
There is also a air-relief nipple with thread G1/2 (4), a water-drain nipple with thread G1/2 (5) from the butt end of WKH. The air is heated during its passage through the heat exchanger in the process of interaction with copper tubes and aluminum plates.
For WKH a surface mount sensor is possible to apply instead of immersion sensor. Water heaters are supplied without temperature sensors and frost protection. To avoid emergency situations during exploitation of WKH, please provide the water flow excluding a possibility of freezing of WKH.
