The energy-optimised compressor series from Danfoss is especially designed for less stable supply voltage and tropical conditions. The …KTK series using R600a is reliable and efficient even under high ambient temperatures or large voltage fluctuations and therefore perfectly suitable for regions with more critical operating conditions. 

Building on many years of experience with hydrocarbon refrigeration systems, the Danish-based company is now adding the …KTK compressor series to the hydrocarbons21.com database. Thanks to the optimisation of the motor, pump and gas flow, the compressors are even more efficient and quiet. The compressor series has been particularly designed for critical operation conditions, such as high ambient temperatures up to 43 °C or 110 °F. Even heavy under voltages due to less stable power supply in general can be handled easily by offering the well-known Danfoss quality, high efficiency and cost optimisation.

Applications for the Danfoss’ …KTK compressor series are mainly household refrigerators and freezers, while the 115 V 60 Hz types also can be used in bottle coolers and similar shop equipment.
