HxWxD [mm]
¹ Condensing unit; evaporation temperature t₀ -30°C, ambient temperature + 32°C; evaporator superheat 10K; influences of installation location and other refrigeration circuit
components must be considered independently
² Basis of calculation for room size: room temperature -21°C, ambient temperature +25°C
Heat extraction from goods 15K, operating time 16 h/day, goods handling 1/7 per day, inspection and lighting 0.5 h / day
³ Max. compressor inlet superheat 20K
⁴ Based on AR6 / IPCC
⁵ Condensing unit, A-weighted equivalent sound pressure level at a distance of 10m
