Variable Flow Heat Transfer Systems (HTS-VF)

EnviroSep Model HTS-VF, Variable Flow Heat Transfer System provides significant power savings by automatically controlling pump(s) speed based on the actual building system demand. Typically, Differential Pressure Transmitters are placed across the building heating system zone loops, signaling the Variable Speed Controller to operate the pumps at the appropriate conditions to meet demand. The Model HTS-VF may be controlled by other system variables, such as Total System Load (BTU/hr), System Pressure, or System Temperature via a customized Controller. Variable Frequency Drives may be incorporated with Manual or Automatic Bypasses. A User-friendly, Color Touch Screen Operator Interface and Non-proprietary, PLC-based Controller is utilized for simple operation. The Model HTS-VF Controller may be furnished with Interface to any Building Management System. This fully integrated turn-key system speeds installation and start-up which provides significant, initial-investment savings to contractors, engineers, and building owners.
