Emerson 4DK3R22ME-TSK-800 Semi-hermetic Discus Compressor

Product Description

The EMERSON 4DK3R22ME-TSK-800 is a semi-hermetic Discus compressor designed for refrigeration and air conditioning systems using R22 refrigerant. Semi-hermetic Discus compressors are known for their serviceable construction, allowing field access to internal components without full replacement. This unit operates on a three-phase electrical supply rated at 208-230-460 volts, making it suitable for a range of commercial power configurations. It is installed by licensed HVAC-R technicians in commercial refrigeration or large commercial cooling applications where robust, serviceable compressor technology is required.

This compressor is intended for commercial HVAC and refrigeration systems running R22 refrigerant. The three-phase voltage rating of 208-230-460 volts makes it adaptable to multiple commercial power supply configurations. Suction and discharge connections measure 1-3/8 inches and 2-1/8 inches respectively, which are standard sizes for commercial semi-hermetic compressor installations. This unit fits into mid-to-large commercial refrigeration racks, condensing units, and central cooling systems where field-serviceable compressors are specified.

Key Features

• Semi-hermetic Discus design allows field service and internal component access
• R22 refrigerant compatibility for existing legacy commercial systems
• Three-phase operation at 208-230-460 volts for commercial power flexibility
• 1-3/8 inch suction connection and 2-1/8 inch discharge connection
• Robust construction suited for continuous commercial duty cycles

Compatibility

Designed as an OEM-style replacement semi-hermetic Discus compressor for commercial R22 refrigeration and air conditioning systems requiring a three-phase 208-230-460 volt compressor with 1-3/8 inch suction and 2-1/8 inch discharge connections.

Installation Notes

Installation must be performed by a licensed HVAC-R technician holding the appropriate EPA Section 608 certification for handling R22 refrigerant. Disconnect and lock out all power before beginning any compressor replacement work. Recover all refrigerant from the system in compliance with EPA regulations before disconnecting refrigerant lines. Follow the equipment manufacturer's specifications and local mechanical codes for oil charge, suction and discharge line sizing, and electrical connection torque requirements.
