The proprietary technology of the E-Star® HiPerForm® condensing unit has historically made it the most energy-efficient milk cooling system in the world. As technology has developed, so has the HiPerForm. The mechanical subcooling valve has been replaced with an electronic subcooling valve and control. The electronic control processes data for a tenth of a second, making the proper adjustments to the electronic valve. These advancements result in nearly no install setup and provide the highest energy efficiency with faster milk temperature pulldown times.
