The Rheem H2AC™ Rooftop Unit featuring eSync™ Integration

The Rheem H2AC Packaged Rooftop Unit™ with eSync Integration Technology™ works by taking the heat removed from the HVAC system—which would normally be rejected into the atmosphere—and then uses it to heat water. Specifically, the unit switches from a refrigerant-to-air system, to a refrigerant-to-water system, when a restaurant has demand for air conditioning and hot water.

YORK® YVWA variable-speed water-cooled screw chiller

The Johnson Controls’ YORK® YVWA variable-speed water-cooled screw chiller has a variable-speed drive that saves energy during the 99 percent of operating hours spent at off-design conditions, when building loads and/or tower-water temperatures are lower. It increases sustainability by using HFC-134a refrigerant, and the design reduces the number of potential leak points by 35 percent, said the company. The YVWA screw chiller is capable of handling a higher pressure lift than a centrifugal chiller, it can be used in both thermal-storage and heat-pump applications, while delivering the highest efficiencies available, the manufacturer stated.

TT400 380V

The TT400 380V model is an oil-free, variable-speed, magnetic bearing centrifugal compressor. It uses HFC-134a refrigerant for an optimum environmental solution and provides outstanding part load and full load efficiency. The compressor is lightweight, emits low sound and vibration, includes self-contained intelligent controls, and utilizes a small footprint compared to other compressor technologies. Its oil-free design makes it very low maintenance and its small stature allows for hassle-free installation. Its self-contained intelligent controls allow for constant monitoring, making diagnosis and repairs in the field much easier than conventional compressor applications.
