The YORK YVWH Water-to-Water Dual Variable Speed Screw Heat Pump supports simultaneous heating and cooling functions and can be operated in three modes: heating only, cooling only or simultaneous heating and cooling. Especially advantageous for high-temperature hot water heating applications, it is the first screw heat pump that can provide water temperatures up to 176 degrees Fahrenheit (80 degrees Celsius). At that temperature, the unit can provide 4,050 MBH of heating while simultaneously providing 200 tons of chilled water cooling at 41 degrees Fahrenheit (five degrees Celsius). It also features variable-speed drive and has excellent turndown that allows it to run with as low as 25 percent of the design-heating load.
