A series of high efficiency Danfoss Optyma condensing units without a case, cooled by air, equipped with hermitic reciprocating compressors and micro-channelled condensers. The units are adapted for low and medium temperate cooling applications, such like: industrial cooling, milk cooling, refrigeration compartments in the stores, retail cooling furniture. Dedicated to operating with a lot of refrigerants, also with low GWP.

Danfoss condensing units facilities cost reduction, lower energy consumption, lower maintenance costs and silent work, thanks to 6-pole motor in AC fan. High efficiency micro-channelled condensers can operate in high temperature environment up to +46°C.

A variety of factory tests and quality components ensure a longer service life and lower warranty repair costs. High COP energy efficiency, low energy consumption and low GWP refrigerants guarantee cost savings and care for the environment.

The package of standard Danfoss Optyma condensing units includes hermetic reciprocating compressor (MTZ/NTZ), base plate, microchannel condenser, fan (one or two) with 6-pole AC motor, dual pressure control, electrical box and liquid reservoir.

Optimized microchannel condenser, easy access to components, metric and inch valves and check valves facilitate assembly and maintenance of the units. The compact design and small dimensions make it easy to carry and transport the unit. Corrosion-resistant microchannel heat exchanger designed for indoor and outdoor use.

Advantages of microchannel condenser:

  • system COP optimization (lower condensing temperature)
  • higher thermal efficiency compared to plate capacitors
  • up to 35% less refrigerant in the cooling system
  • much stronger and lightweight than conventional fins
