The Danfoss MT125-3VI is a high-performance hermetic reciprocating compressor primarily designed for medium to high evaporating temperature applications. As part of the Maneurop MT Series, this 4-cylinder unit is engineered to handle R22 refrigerant using a pre-charged mineral oil (160P) lubricant. This three-phase compressor operates at 200-230V and 60Hz, delivering a nominal capacity of 124,678 Btu/h. Its fully gas-cooled motor ensures total motor protection by passing all suction gas through the windings before compression, effectively eliminating the need for external cooling even in high-demand refrigeration cycles. For field installations, the MT125-3VI features versatile rotolock connections, including a 1-3/4" suction port with a 1-1/8" ODF sleeve and a 1-1/4" discharge port with a 3/4" ODF sleeve. The inclusion of a 3/8" NPT oil equalization port and a threaded sight glass makes it an ideal candidate for parallel manifold configurations. The large internal free volume provides superior resistance to liquid slugging, a critical factor for technicians managing systems with significant refrigerant charges. Key Benefits: High Volumetric Efficiency: Advanced circular valve plate design reduces internal pressure losses and heat transfer. Robust Liquid Handling: Massive internal housing protects components from damage during liquid refrigerant migration. Standardized Fit: Rotolock valves and supplied solder sleeves simplify direct replacement in existing HVACR systems. Advanced Motor Protection: Built-in internal overload protector guards against overheating and electrical fluctuations. Parallel Compatibility: Pre-drilled oil equalization connection allows for easy integration into multi-compressor racks. Common Questions: What oil is required for the MT125-3VI? This model is specifically designed for mineral oil. If you are converting to HFC refrigerants, the MTZ series with POE oil is typically required. Is this unit compatible with 208V systems? Yes, the 200-230V/3/60Hz motor rating is fully compatible with standard 208V three-phase commercial power supplies. Does this compressor include a mounting kit? Yes, the package includes the motor-compressor, rotolock nuts, gaskets, solder sleeves, and the necessary rubber grommets and bolts for installation. This item is not eligible for free shipping.
