Quick-release type designed for pipes of size 10 x 3 mm External water supply flow rate 0.6 l/min/kW (at 12 ºC tap water inlet temperature) External water supply pressure 0.5 - 5 bar KMW3000C Version 1 USER MANUAL Page 5 KMW3000CChiller v1.1.doc... -
Page 10: Technical Description
4.2 Operating Principles 4.2.1 Tap water circuit Tap water from the mains supply passes through a filter on the front of the KMW3000C. The water then enters the unit through a manual cut-off valve, before passing to the temperature-modulated valve. The temperature-modulated valve controls the temperature stabilisation in the closed water circuit, and the consumption of tap water. -
