ASPERA - EMC 3117U R290 COMPRESSOR
The Aspera EMC 3117U compressor is a hermetic refrigeration compressor designed primarily for use in low- and medium-back-pressure (L/MBP) systems, operating with the environmentally friendly refrigerant R290. Its construction is based on a small piston displacement — just 3.97 cm³ — which makes the unit compact and relatively lightweight (around 8.2 kg).
In terms of performance, under typical operating conditions (evaporation at −6.7 °C and condensation at +54.4 °C), the nominal cooling capacity is 331 W. Additionally, data is available for various evaporation temperatures (e.g., from −25 °C to 0 °C), showing variations in capacity, power consumption, and gas flow. The compressor is powered by 220–240 V, 50 Hz.
