Carrier Corp.’s new system, the AquaForce 30XW water-cooled screw chiller, produces hot water at a controlled temperature to maximize heat recovery and increase the overall system efficiency. The chiller uses a non-ozone-depleting HFC-134a refrigerant to exceed ASHRAE 90.1 standards. The system measures 48 inches wide and is available in 150- to 400-ton models. All models comply with International Building Code and ASCE 7 seismic qualifications in concurrence with ICC ES AC156 Acceptance Criteria. According to company officials, the AquaForce 30XW is 20-percent more efficient than its competitors, resulting in paybacks as low as one to two years or three to four months with an auxiliary chiller. carrier.com; 800.227.7437.
