Notes: Evaporator ΔT = 5 K The evaporator is protected against frost down to -20°C. Legend: Standard unit operating at full load. Operating range, units equipped with options 28, 28B, 28C “Winter operation”. Option 28 (with variable-speed lead fan for each circuit) allows operation down to -20°C outside temperature. Options 28B, 28C (with two-speed lead fan for each circuit) allows operation down to -10°C outside temperature. In addition to options 28, 28B, 28C the unit must either be equipped with the evaporator frost protection option (for units without hydronic module option) or the evaporator and hydronic module frost protection option (for units with hydronic module option) or the water loop must be protected by the installer by adding a frost protection solution.
For application requiring operation at less than 8 or 6.8°C respectively, contact Carrier for unit selection using the Carrier electronic catalog. ** For an application, requiring operation up to +15°C leaving water temperature, contact Carrier for the selection of the unit. *** For operation from 0°C to -10°C the units must be equipped with options 28B, 28C “Winter operation”. For operation from 0°C to -20°C the units must be equipped with option 28 “Winter operation”. For both options the unit must either be equipped with the evaporator frost protection option (for units without hydronic module option) or the evaporator and hydronic module frost protection option (for units with hydronic module option) or the water loop must be protected against frost by the installer, using an anti-freeze solution. Maximum outside temperature: For transport and storage of the 30RB units the minimum and maximum allowable temperatures are -20°C and +48°C. It is recommended that these temperatures are used for transport by container. **** Unit with fans with available pressure up to 200 Pa. † 30RB 162 units use options 28B, 28C for outside temperatures below 10°C.
