Combined Chilled & Hot Water System

Combined Chilled & Hot Water Packaged Pumping System - Constant Primary / Variable Secondary

EnviroSep HW-CHW, Combined Chilled and Hot Water, Constant Primary / Variable Secondary, Packaged Pumping System is a UL-Listed, factory manufactured system utilized in conventional building heating and cooling systems which uses Chilled Water as the cooling medium and Hot Water as the heating medium. The Model HW-CHW combines both the chilled and hot water systems into a single, pre-packaged system which is factory-tested and ready for start-up. The Secondary Pumps are Variable Speed controlled 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. The Model HW-CHW 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 HW-CHW 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.
