Copeland—an Emerson brand—is a global leader in HVACR compression technology, trusted for supermarkets, cold rooms, process cooling, and transport refrigeration. The portfolio spans semi-hermetic reciprocating compressors (D-/3D/4D/6D families), scroll compressors, and complete condensing units engineered for high efficiency, long service life, and easy serviceability. Semi-hermetic models such as the D-series (e.g., D3…/D4…/D6…) feature robust valve-plate/discus designs, wide operating envelopes for LBP/MBP/HBP applications, integrated motor protection, crankcase heaters, and oil-management options—making them ideal replacements or upgrades in legacy racks and new builds alike. Copeland supports common refrigerants used in commercial refrigeration (R404A, R407F, R448A/R449A, R134a, and selected low-GWP alternatives), helping end users meet efficiency and compliance targets while maintaining reliable pull-down in hot climates.
