Water Drawback Valve, R1/8

An indirect dry cooling system is characterized by the use of a condenser and air-cooled heat exchangers.The cooling system consists of the following main components :condenser (surface or spray type),cooling water circulating pumps and recovery turbines, if applicable,heat exchanger deltas including louvers,natural draft cooling tower,piping and valves,water storage tanks and transfer pumps,electrical equipment,instrumentation and control,accessories such as cleaning system, nitrogen blanketing system,The warm water from the condenser is delivered to the natural draft cooling tower by the cooling water circulating pumps and an underground piping network. After the cooling in the heat exchangers, the cold water returns to the condenser.

This fan speed controller is used to control EC fan speed. The unregulated output can control a water valve or an electric heating element. Via the rotary knob the temperature can be set between 5 - 35°C. Fan speed is regulated manually in 5 steps, there's an Off-position and automatic mode. In automatic mode a temperature sensor PT500 is required. Choice between cooling/heating mode can be done via Modbus communication or a jumper. This controller can be connected to our SenteraWeb or a BMS-system. .
