Green series

Pro-Edition

With the new „Pro Edition“ you are also on the safe side in the long term regarding the restrictions on use (F-Gas-Regulation). Perfect tailored for respective commercial cooling and air conditioning our series enables by using propane (GWP: 3) or propene (GWP: 3) an almost emission-free refrigerant charge at highest energy efficency.

cooling capacity5 kW to 1.800 kW

outlet temperature+ 15 to – 20 °C / 0 bis – 25 °C
Umgebungstemperatur- 10 to + 42 °C

Cascade chiller (low temperature)

Our cascade chillers specially designed for the commercial cooling and freezing use only natural refrigerants and provide the generated cooling capacity in two temperatur ranges.

  • normal temperature: +15 to -25 °C (R290 propane or R1270 propene)
  • low temperature: -10 to -30 °C (R744  available as indirect system or direct evaporation up to -50 °C)
cooling capacity5 kW to 750 kW
refrigerantR290 / R1270 and R744
outlet temperature+ 15 to – 20 °C / 0 to – 25 °C and – 10 to - 30°C
ambient temperature- 10 to + 42 °C

Cascade chiller (ultra low temperature)

Our product portfolio contains a cascade chiller based on ethane (R170) for the ultra low temperature cooling below - 30 °C (e.g. test chamber). In addition to air conditioning and normal cooling by propane/propene, the use of ethane also allows the temperature to be reduced to - 60 °C.

  • normal temperature: +6 to -10 °C (R290 propane or R1270 propene)
  • ultra low temperature: to -60 °C (R170 ethane available as indirect system or direct evaporation up to -70 °C)
cooling capacity5 kW to 250 kW
refrigerantR290 / R1270 and R170
outlet temperature+ 15 to – 20 °C / 0 to – 25 °C and – 20 to -40°C
ambient temperature- 10 bis + 42 °C

NH3 - Chiller

Maximum efficiency at minimal costs. Through the implementation of semi-hermetic-screw-compressors, the advantages of the best refrigerant R717 (ammonia) are optimally used. This enables the savings in investment (lower material requirement) as well as in operational costs (higher efficiency).
