The Grundfos PACOpaQ® is a fully-integrated and compact HVAC packaged pumping system designed for chilled and hot water distribution, condenser water, geothermal loop, district heating and cooling, and many other water-based systems. The system pairs centrifugal pumps with the intelligence and efficiency of a dedicated HVAC control, which automatically determines the most efficient speed and optimum number of pumps needed to meet desired flow and pressure.

Ideal for HVAC pumping applications in schools, hospitals, commercial buildings, and industrial plants, the system offers multiple configurations — with up to four pumps in parallel — to accommodate a complete range of end suction and vertical in-line pumping needs.

Heat exchangers are included in the PACOpaQ as well as expansion tanks, hydraulic separators, and tangential air separators — also available separately. The company says these components work together to provide lower initial cost, longer pump life, reduced maintenance, maximum efficiency, and quieter operation for the end user.
