Energy Savings  •  Lower System Friction Losses
Water Temperature in Individual Units  •  Diversified Fan-Coil Product Line
Temperature Control  •  Superior Humidity Control

The Whalen rise heat-exchanger system is fully compatible with both variable speed pumps and multiple pumps piped in parallel so that individual pumps can be shut down under part-load conditions. The small reduction in Whalen unit capacity when the riser water flow is reduced is usually more than offset by the capacity increase that results from reduced average water temperatures at part load (when some units on the riser will normally be turned off or their thermostats will not be calling for cooling). Instead of attempting to force the chilled water pump back up its curve far enough to trip a pressure switch, all that is required with the Whalen system is a return water temperature sensor to control the chilled water pump (similar to most chiller controls). The Whalen Company recommends that the system designer consider possible energy savings with reduced pump horsepower at part-load conditions within the building envelope.
