Emerson 4DE3R18ME-TSK-800 Discus Compressor R22 3-phase

Product Description

The EMERSON 4DE3R18ME-TSK-800 is a Discus-style refrigeration compressor designed for commercial and industrial refrigeration systems using R22 refrigerant. It operates on 208-230-460 volts at three-phase power, making it suited for commercial equipment rooms and rooftop systems where three-phase service is available. The suction connection measures 1-3/8 inches and the discharge connection measures 1-5/8 inches. Discus compressors are known for their semi-hermetic design with efficient valve technology, and this unit follows that same construction. Installation is typically performed by licensed refrigeration or HVAC technicians.

This compressor is intended for commercial refrigeration applications where R22 is the system refrigerant. The three-phase voltage configuration supports 208, 230, or 460-volt service, giving installers flexibility across different electrical setups. Typical use cases include walk-in coolers, reach-in cases, and other commercial refrigeration equipment requiring a semi-hermetic reciprocating compressor. It is field-serviceable, which is a standard characteristic of the Discus product line. Only technicians certified to handle refrigerants under Section 608 of the Clean Air Act should service this unit.

Compatibility

Designed as an OEM-style replacement compressor for commercial R22 refrigeration systems requiring a three-phase Discus semi-hermetic reciprocating compressor with 1-3/8 inch suction and 1-5/8 inch discharge connections.

Installation Notes

Installation must be performed by a licensed HVAC or refrigeration technician holding EPA Section 608 certification for handling R22 refrigerant. Disconnect and lock out all electrical power before servicing the system. Follow NEC guidelines for three-phase wiring and verify that the available voltage matches the compressor nameplate rating before energizing. Do not operate the compressor without confirming proper refrigerant charge, oil level, and system pressures according to the original equipment manufacturer specifications.
