HKT Goeldner-Compressors for hydro-carbon refrigerants, especially propane (R290) are successful in operation since more than 20 years. With the modified models the application range was widened again. This works without any losses neither efficiency nor safety in operation.
With the R290-compressor range “P” HKT Huber-Kälte-Technik fulfilled the strong demand on climate neutrally solutions for refrigeration an air-conditioning applications as well as heat pumps. HKT-Compressor – Manufactory now offers for each customer a suitable product. On Chillventa 2018 HKT will display a high temperature chiller for max ambient temperature up to 100°C, working with a hydro carbon refrigerant being equipped with a semi-hermetic Goeldner-“P”-Compressor.
GOELDNER COMPRESSOR have proven themselves for decades in many applications. Now the semi-hermetic compressors of the 2-cylinder-series HS 12, HS 22, HS 32 and the 4-cylinder semi-hermetic compressors HS 34 are optionally equipped with a frequency instead of the terminal box. Because of the special lubricating system of the type HS 12 and HS 22 and the shaft bearing with ball bearings, has a working range from 20Hz to 60Hz without major restrictions with the refrigerants R134a, R404A/R507, R407C in all the above mentioned types of Goeldner-motion series.
