Technical specifications

Designed for transcritical CO₂:

LP 100 bar
HP 150 bar

Highest efficiency in the market with COP of more than 1,85
(50 Hz [1450 U/min], evaporating -10°C, gas cooler outlet 35°C/90 bar, superheat 10 K)
Optimised thermal separation and gas flow in the whole compressor for best efficiency
Equipped with oil pump (optimal oil circulation, optional oil pressure control)
Motors for variable speed control with possible frequency range 20-70 Hz
Low oil carry over
Two electronic motor versions for individual applications and operating conditions
3 compressor types:

ML-Version: For medium and low temperature applications at low and medium evaporating temperatures, oil charge C85E
S-Version: For frequency control and extended application range, equipped with more powerful drive motor, oil charge C85E
SH-Version: For heat pumps and at high evaporating temperatures, equipped with more powerful drive motor, oil charge C150E

Suction and discharge line valves with cutting ring or soldering/welding connections (as required)
Equipped with compressor protection tool
