Product Description

Introduction to the Danfoss Refrigeration Compressor Model MT/MTZ 125 HU

The MT/MTZ 125 HUis a classic open-type reciprocating piston refrigeration compressorfrom the Danfoss Maneurop series. This compressor model has a long history of application in the commercial and industrial refrigeration sectors and is renowned for its robustness and high reliability.

Here are the detailed specifications for the Danfoss Maneurop MT/MTZ 125 HU:

Core Overview

Model:MT 125 HU / MTZ 125 HU
Type: Open-type reciprocating piston compressor. This means the compressor and the electric motor are separate units, connected by a shaft seal and coupling, facilitating maintenance and motor replacement.
Brand History:This compressor was originally produced by the Maneuropcompany, which was later fully acquired by Danfoss. Therefore, it is now commonly referred to as a Danfoss compressor. You may find compressors bearing both "Danfoss" and "Maneurop" logos.
Status:A well-proven, stable-performing medium to large commercial compressor.

Key Technical Parameters (Typical Values)

The following parameters are based on standard conditions with specific refrigerants (e.g., R22). Exact values must be checked against the official technical documentation.

Refrigeration Capacity:Approximately between 10 kWand 15 kW(depending on evaporation temperature, condensation temperature, and the refrigerant used). This makes it suitable for applications requiring significant cooling capacity.
Piston Displacement: 125 cm³(This is what the "125" in the model number signifies).
Suitable Refrigerants:

Traditional Refrigerants: R22, R12, R502 (the latter two are largely phased out).
Modern Alternative Refrigerants:With necessary modifications (e.g., changing lubricant), it can also be suitable for R404A, R507, R134a, etc. Strict adherence to official guidelines is mandatory when selecting and using alternative refrigerants.

Lubricant:Typically uses Mineral Oil (for R22) or Alkylbenzene Oil. If changing refrigerants, it must be switched to a compatible lubricant like POE ester oil.

Main Features

Open-Type Design:

Advantages:The motor is separate from the compressor. If the motor burns out, it doesn't contaminate the entire refrigeration system; only the motor and filter-drier need replacement, resulting in relatively lower repair costs. Allows for higher power ratings.
Disadvantages:Requires a shaft seal, which poses a potential risk of refrigerant leakage. Requires a belt or coupling for drive, making the structure relatively more complex.

Robust and Durable:

Cast iron body with a sturdy internal structure, designed for industrial-grade continuous operation and long service life.

High Energy Efficiency:

For its time, this compressor offered competitive energy efficiency ratios.

Wide Range of Applications:

Suitable for various medium and low-temperature applications.

Typical Applications

Given the MT 125 HU's significant displacement and cooling capacity, it is typically used in medium to large commercial refrigeration systems:

Condensing units for medium-sized cold storage rooms
Process cooling in the food industry
Equipment within large supermarketrefrigeration systems
Marine refrigeration
Ice rinkrefrigeration systems

Model Number Interpretation

MT/MTZ:Series code for Maneurop open-type compressors.
125:Piston displacement, in cubic centimeters (cm³) - a key indicator of compressor size.
H:Often indicates the compressor series or design version.
U:May indicate specific electrical configuration or mounting dimensions.

Important Notes

Modern Alternatives:The MT/MTZ 125 HU is an older model. With increasing environmental and energy efficiency requirements, Danfoss has introduced more modern and efficient alternatives, such as scroll compressorsor semi-hermetic/hermetic variable-speed compressorsdesigned for new environmentally friendly refrigerants (like R448A, R449A).
Selection Requires Caution:Selection must never be based solely on the model name. It is essential to consult the latest official Danfoss technical manuals and selection softwareto determine the compressor's exact performance parameters (capacity, power input, current, etc.) based on your specific refrigerant, evaporation temperature, and condensation temperatureconditions.
Maintenance:For this open-type compressor, the shaft sealis a critical point for periodic maintenance to prevent leaks. Additionally, ensuring the motor bearings are properly lubricated is crucial.
