The range of hermetic reciprocating compressors Danfoss MTZ was designed for different applications in medium and high evaporating temperature refrigeration systems. Compressors are adapted to work on refrigerants from the A1 group: R448A, R449A, R452A, R134a, R407C, R407A, R407F, R513A, R404A and from the A2L group: R454C, R455A with a lower GWP coefficient. Models with capacity range from 5.3 to 47.3 m³/h are characterized by a low energy consumption optimizing labor costs, compact design, ensuring good acoustic parameters. The compressors are intended for small, commercial refrigeration installations: refrigeration cabinets, low – temperature racks, freezers and cooling chambers, ice cream machines.

Applications:

  • high and medium evaporating temperatures
    • (R404A from -30 °C to 10 °C)
    • (R448A/R449A from -30 °C to 10 °C)
    • (R134a from -25 °C do 15 °C )
  • Walk-in freezers and cold rooms
  • Frozen food processing and storage
  • Blast freezers
  • Low temperature racks
  • Ice cream machines
  • Display cabinets
  • Water chillers
  • Large packaged air condition

MTZ series features:

  • displacement from 5,3 to 47,3 m³/h
  • cooling capacity:
    • from 1,9 kW to 20,3 kW (for te=-10 °C, tc=45 °C, SH=10K, SC=0K, R404A)
    • from 1,8 kW to 20,1 kW (for te=-10 ºC, tc=45 ºC, SH=10K, SC=0K, R448A/R449A)
  • filled with polyester oil (175PZ)
  • 100% suction gas-cooled motor

MTZ compressors are characterized by a large internal volume, large oil sump and sturdy design. They are powered by 100% refrigerant gas-cooled motor,  which means that they do not require additional cooling. No need for air circulation around the compressor. Long lifetime expectancy and reliability.

Small commercial compressors are available with a wide range of cooling capacities. Operation under extreme conditions. They are characterized by low energy consumption optimizing labor costs, compact structure and ensure good acoustic parameters.

Standard equipment

  • rubber vibration absorbers
  • oil sight glass
  • oil equalization

Optional equipment

  • crankcase heater
  • belt type heater
  • Rotalock valves
  • soft-start kit
  • accoustic hood

MTZ series advantages:

  • Large internal volume, and oil sump
  • Internal motor protection
  • 100% suction gas-cooled motor
  • High efficiency circular valve design
  • Operation under extreme conditions
  • No need for air circulation around the compressor
  • Long lifetime expectancy and reliability
  • The compressors fit in lots of different applications
