RWD CONTROLLER’S

  RWD CONTROLLER’S

•The RWD family of Universal Controllers are intended for heating, air conditioning, ventilation and refrigeration in comfort control applications.

•OUR WORKS( HUMIDIFICATION PLANT AUTO CONTROL)•Based on the Department Relative Humidity the pump & Fan are ON/OFF Automatically.•Single pump(Fan ON/OFF) Control.•TWO pump(Fan ON/OFF) Control.

•RWD controllers and other types of controllers

APPLICATIONS

•RWD62U/68U/82U main loop control applications are designed for temperature, static pressure, humidity, air pressure, fluid pressure, refrigeration, air quality and air fluid velocity control. The controller contains pre-programmed applications.

•The universal RWD32/RWD82/RWD68 controllers are used for comfort control in HVAC systems.

•Two digital outputs selectable between 2 stages of on/off control or as a single 3 point controller.

•The main analogue input can be set as °C, °F, % or no specified unit.
