AquaForce® High-Efficiency Indoor Liquid Screw Chiller
30HX

75 to 265 Nominal Tons

30HXA - Condenserless
30HXC - Water-Cooled

The 30HX units are high-efficiency, indoor water-cooled or condenserless chillers. The units have a quiet, low-vibration design featuring screw compressors. The 30HX chillers are compact enough to fit through a standard door, making them great replacement units.

Water-cooled chillers within the scope of the AHRI WCCL certification program are certified in accordance with the AHRI Water-Cooled Water-Chilling and Heat Pump Water-Heating Packages Certification Program, which is based on AHRI Standard 550/590 (I-P) and AHRI Standard 551/591 (SI). Certified units may be found in the AHRI Directory at www.ahridirectory.org. Condenserless versions of these units and 50 Hz. units below 200 Tons are not certified under the AHRI certification program.

NOTES
1. Rated (60Hz unit) in accordance with AHRI Standard 550/590 at standard rating conditions.
2. Standard rating conditions are as follows:

Evaporator Conditions:
Leaving Water Temperature: 44°F (6.7°C)
Flow: 2.4gpm per ton (0.043 L/s per kW)

Condenser Conditions:
Entering Water Temperature: 85°F (29.4°C)
Flow: 3.0gpm per ton (0.054 L/s per kW)

Fouling Factor (Evaporator):
0.00010 hr x sq ft x °F per Btuh (0.000018m² x K per W)

Fouling Factor (Condenser):
0.00025 hr x sq ft x °F per Btuh (0.000044m² x K per W)

3. IPLV is a single number part load efficiency value calculated from using the efficiency values at 100%, 75%, 50%, and 25% of load when the chiller is operating in AHRI conditions.
4. All data in the above table was generated in Packaged Chiller Builder version 3.59i. Please refer to the most current version of the Packaged Chiller Builder for the most up-to-date data.
