LPA® Liquid Refrigerant Pumps

Many thousands each year are installed as a retrofit option which comprises of a LPA® pump and a controller to improve system performance and save energy in refrigeration or process equipment when minimum head pressure controls are set to reduced head pressures or if liquid lines are long or have high vertical rises to the expansion valves. The LPA® pump eliminates the usual problems of capacity loss and poor oil return due to operating with low condensing pressures also known as Floating Head Pressures.
