Note
:
1. The nominal cooling capacities (stated above) are at chilled water temperatures of 12/7˚c and ambient of 46˚c.
2. Fouling Factor of evaporator is 0.086 m2.·k/kW.
3. Specification may be changed without further notification.
4. The unit conforms to standard ARI 550/590-98.
5. The cooling capacity and power supply is measured with the economizer at the nominal operating conditions defined in Note 1 above.
6. Noise dB : Sound pressure level at 10 meters.
