The PolyCool superheat package controls and lowers the outlet temperature of compressors, lowers the condenser pressure, has precise superheat at all load conditions and reduces the risk of flash-gas with more sub-cooling. The package controls superheat in dry expansion evaporators, preventing expansion in chillers or direct expansion for air applications. The package includes the hermetic M2FE valve which ranges from capacities 7 kW (2.0 TR) to 100 kW (28.4 TR). The PolyCool Superheat package is pre-programmed in the controller for the following refrigerants: R22, R134a, R404a, R407c, R507, R290, R717, and R1270. It features control of maximum operating pressure and security shut-off for the compressors.
