Multiaqua is an air-cooled chiller system designed to satisfy the requirements of the global residential and commercial markets including, but not limited to, new construction, retrofit, add-on, process, hydronic and Do-It-Yourself (DIY) market segments.

Multiaqua is available in 3, 4, and 5-ton cooling capacities and is matched with a variety of indoor fan coils, unsurpassed in application flexibility. Multiaqua is a self-contained chiller unit with no add-on modules or additional assembly needed to make chilled water. Multiaqua is designed with great care to provide easy service access and readily available components. Multiaqua works using the basic refrigeration cycle. R-407c refrigerant is circulated through the system by a Copeland Scroll compressor which increases the pressure and temperature of the refrigerant and pumps it into the condenser coil. In the condenser, the refrigerant vapor is cooled as air passes over the coil using two, fractional horsepower, fan/motor assemblies configured for horizontal discharge. The refrigerant then condenses into liquid. The liquid refrigerant flows through a thermostatic expansion valve where the flow is metered. The pressure and temperature are reduced.

After passing through the expansion valve, the refrigerant flows into a brazed plate heat exchanger where it boils by absorbing heat from the water passing through parallel circuits of the heat exchanger. As the refrigerant starts the trip back through its self-contained cycle, the newly chilled water passes through a stainless steel head, fractional horsepower pump.

The waters head pressure is boosted such that it travels at a specific flow rate (GPM) into the home or other conditioned spaces that are to be cooled. As this chilled water flows through any one of a myriad of fan coil combinations, it passes through a copper coil.

Air is moved across the coil and the chilled water absorbs the heat of the space. Cold, dehumidified air is then supplied to the conditioned space. 

One of the unique benefits of Multiaqua is the fan coil selection. Multiaqua can be matched with any one or a multiple of chilled water fan coils as listed and schematically presented on our Product Page or our Online Catalog.
