Series of high-performance Danfoss condensing units without housing, equipped with hermetic reciprocating compressors and microchannel condensers. These units are designed for low- and medium-temperature refrigeration applications such as industrial process cooling, milk cooling, cold rooms in stores, and commercial refrigerators and freezers. The units support a wide range of refrigerants: R448A, R449A, R452A, R134a, R407A/C/F, R404A/R507, R22, R290, R513A. Danfoss Optyma units ensure lower energy consumption, reduced operational costs, and quiet operation thanks to the use of a 6-pole AC fan motor. High-efficiency microchannel condensers enable operation in higher ambient temperatures up to +46°C.

Extensive factory testing and high-quality components ensure a longer service life and reduced warranty repair costs. High energy efficiency (COP), low power consumption, and low GWP refrigerants guarantee cost savings and environmental protection.

The standard equipment of Danfoss Optyma condensing units includes a hermetic reciprocating compressor (MTZ/NTZ), base plate, microchannel condenser, one or two fans with a 6-pole AC motor, dual KP pressure switch, electrical box, and liquid receiver.

Optimized microchannel condenser, easy access to components, metric and imperial valve connections, and shut-off valves provide easy installation and service of the units. The compact design and small dimensions ensure easy handling and transport. The corrosion-resistant microchannel heat exchanger is suitable for both outdoor and indoor use.

Advantages of the Microchannel Condenser

  • Optimization of system COP (lower condensing temperature)
  • Higher thermal efficiency compared to finned condensers
  • Up to 35% less refrigerant volume in the system
  • Significantly stronger and lighter than traditional finned condensers
