* Minimum cooling water flow
Notes:
- Fuel input is based on HIGHER HEATING VALUE of gas.
- Specifications are based on water in all circuits and fouling factor of 0.0005 ft2hr.°F/Btu.
- Do not exceed 114 psi operating pressure in any water circuit.
- Chilled/hot water flow limits are 80~120% of standard rating.
- Cooling water flow limits are 100~120% of standard rating.
- Two or more modules may be installed in parallel for larger capacities.
- Standard natural gas supply pressure is 7.0 in. wc.
- Sound pressure noise level measured in a free field at a point 39 in. in front of the chiller-heater and 59 in. above the ground.
