Technical data Cooling capacity Speed 30 RPS NOTES: * Preliminary data of VZH 4-7TR, subject to change. Cooling capacity Speed 25 RPS Efficiency High pressure ratio Efficiency Low pressure ratio RATING Conditions: (1) Part load: Evaporating Temp: 45°F/7.2°C; Condensing Temp 95°F/35°C; Superheat 20°F/11.1K; Subcooling 15°F/8.3K - The cooling capacity of the small platform can be modulated from 100 to 15RPS, thus the minimum cooling capacity for the VZH044, for example, will be of 1TR. (2) ARI: Evaporating Temp: 45°F/7.2°C; Condensing Temp 130°F/54.4°C; Superheat 20°F/11.1K; Subcooling 15°F/8.3K...
