Variable Speed ​​Pumps ITT has released a variable speed pump controller for HVAC and pressure-driven equipment. The variable speed pump controller from ITT is less expensive and more energy efficient due to its clever combination of hardware platform and advanced software operating system. The new 502 pump controller and the adjustable drive from ITT provide controllers for four parallel pumps, including four input modules, including zone sensors, flow sensors, suction sensors, user records, etc., to solve the second Level, the third level, high temperature, cooling water, booster pump some specific applications. The built-in protection keeps the pump free of water pressure disturbances caused by excessive flow rates.
