Operating on a \u003cstrong\u003e460V 3-phase\u003c\/strong\u003e power supply, this 4.5 HP \u003cstrong\u003eManeurop MTZ series\u003c\/strong\u003e unit is factory-charged with \u003cstrong\u003e175PZ polyol ester oil (POE)\u003c\/strong\u003e, making it compatible with a broad range of HFC, HFO, and HCFC refrigerants including \u003cstrong\u003eR404A, R407C, R134a, R407A, R448A, and R513A\u003c\/strong\u003e. Its robust construction features a large internal free volume that effectively mitigates the risk of liquid hammering, while the 100% suction gas-cooled motor ensures thermal stability during high-demand cycles. Designed with \u003cstrong\u003erotolock connections\u003c\/strong\u003e (1-3\/4\" suction, 1-1\/4\" discharge), this \u003cstrong\u003ecommercial HVAC compressor\u003c\/strong\u003e facilitates rapid installation and field serviceability. Whether you are performing a \u003cstrong\u003ereplacement compressor\u003c\/strong\u003e install or building a new rack system, the \u003cstrong\u003eMTZ50HK4EVE\u003c\/strong\u003e provides the high torque and volumetric efficiency required for reliable 24\/7 operation in demanding environments.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Refrigerant Compatibility:\u003c\/strong\u003e Optimized for use with a wide array of modern refrigerants, allowing for flexible inventory management and future-proofing against shifting regulations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnhanced Liquid Handling:\u003c\/strong\u003e The large internal volume and circular valve design provide superior protection against liquid refrigerant migration and slugging.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal Motor Protection:\u003c\/strong\u003e Integrated overload protection safeguards the 3500 RPM motor from electrical fluctuations and overheating.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandardized Fit:\u003c\/strong\u003e \u003cstrong\u003eRotolock\u003c\/strong\u003e suction and discharge ports, along with a 3\/8\" NPT oil equalization connection, ensure seamless integration into existing \u003cstrong\u003eManeurop\u003c\/strong\u003e system layouts.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the primary difference between the MT and MTZ series?\u003c\/strong\u003e\u003cbr\u003eThe MT series is typically pre-charged with mineral oil for R22 applications, whereas the MTZ series is charged with \u003cstrong\u003e175PZ POE oil\u003c\/strong\u003e to support HFC and HFO refrigerants. Using the wrong oil type in a system can lead to lubrication failure and mechanical breakdown.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan the MTZ50-4VI be used for low-temperature applications?\u003c\/strong\u003e\u003cbr\u003eNo, this specific model is optimized for \u003cstrong\u003emedium and high evaporating temperatures\u003c\/strong\u003e. Attempting to run this unit in low-temperature conditions may lead to insufficient motor cooling and premature failure.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat components are included with the compressor?\u003c\/strong\u003e\u003cbr\u003eTypical shipments include the compressor with an initial oil charge, a mounting kit (grommets and bolts), and rotolock nuts with solder sleeves for suction and discharge connections.\u003c\/p\u003e\n\u003cp\u003eDisclaimer: While we strive for 100% accuracy, product data and specifications are subject to change.
