Danfoss MT18-1VI Compressor

Professionals in clinical and commercial refrigeration depend on the Danfoss MT18-1VI Compressor for its reliable 1.5 HP output and consistent medium to high evaporating temperature performance. This hermetic reciprocating compressor, specifically the MT18JA1PVE model, is engineered for 208-230V single-phase operation at 60Hz. It provides a nominal capacity of approximately 15,903 BTU/hr, making it a staple for R22 refrigerant systems utilizing 160P mineral oil. Built with a large internal free volume, the unit effectively mitigates the risk of liquid hammering, while its 100% suction-gas cooled motor facilitates quiet operation and high efficiency without the need for additional external cooling.

Danfoss MT18-1VI Technical Specifications:
The unit features 1" Rotolock connections with a 1/2" ODF suction sleeve and 3/8" ODF discharge sleeve. Its standard VE configuration includes an oil sight glass and a 3/8" flare SAE oil equalization port for seamless installation in parallel systems. With a 30.23 cm³ displacement and a maximum current continuous (MCC) rating of 13A, this compressor delivers the high torque necessary for demanding start-up conditions in field replacements and new builds.

• Optimized for R22: Specifically designed for R22 refrigerant applications using mineral oil to ensure long-term mechanical compatibility.
• Superior Protection: Equipped with an internal motor protector to prevent damage from overheating or electrical overloading.
• Installation Versatility: Features Rotolock valves for quick, secure mechanical connections in tight mechanical rooms.
• Efficient Gas Management: A unique circular valve design improves volumetric efficiency and reduces internal pressure losses.

What is the correct oil type for the Danfoss MT18-1VI?
The MT series is factory-charged with 160P mineral oil. If you are converting to HFC refrigerants, the MTZ series with POE oil is typically required.

Does this compressor require a hard start kit?
For single-phase 230V applications where high starting torque is required due to unbalanced pressures, a CSR (Capacitor Start Run) or dedicated start kit is recommended.

Can I insulate this compressor for noise reduction?
Yes. Because it is fully suction-gas cooled, you can install an acoustic jacket without the risk of motor overheating.
