Constant Primary / Variable Secondary (CPVS)

Model #CPVS
Chilled Water Packaged Pumping System Constant Primary / Variable Secondary

EnviroSep Model CPVS, Constant Primary / Variable Secondary, Chilled Water Packaged Pumping System is a UL-Listed, factory manufactured system utilized in conventional building cooling systems which uses Chilled Water as the cooling medium. The Model CPVS provides significant power savings by automatically controlling the speed of the Secondary Pumps based on the actual building system demand. Differential Pressure Transmitters (or alternate sensors) signal the Non-proprietary PLC-based, Variable Speed Controller to operate the pumps at the appropriate conditions to meet demand. Chilled Water Return is supplied to the System Chiller(s) and the Chilled Water Supply is decoupled through a common header. The Model HTS-CPVS 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 is utilized for simple operation. The Model HTS-CPVS 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.
