models.
2. Capacity at standard conditions of 95
°
F ambient temperature. Chilled water Outlet temperature 45°F, chilled water Inlet
temperature 55°F. Actual capacity will vary with ambient (condenser) air temperature and leaving water temperature. Capacity
characteristics are shown in the table below. Interpolations between tabled values are permissible, but do not extrapolate. For
capacities at ambient temperatures higher than in table, contact Robur or your authorized distributor.
3.
Fan speed is reduced when external temperature is less than 91.4°F.
4.
Units are factory-wired for 208-230 volts operation.
5.
May vary by ±10% as a function of both power supply and electrical motor input tolerance.
6. "Chilled Water" refers to a solution of quality tap water and 10% by volume of inhibited permanent antifreeze. Higher antifreeze
