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 reliable 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. All components work together to provide lower initial cost, longer pump life, reduced maintenance, maximum efficiency and quieter operation for the end user.
