ModulAIR is a water cooled chiller that brings robust serviceability and ASHRAE 90.1-2010 efficiency into a single compact package. Standard features such as cleanable shell & tube condensers and replaceable filter driers means that customers no longer need to sacrifice reliability when choosing a modular design. Each module can be used as a stand-alone chiller or combined with the optional header system for installations up to 550 tons. The unique control algorithms are duplicated in each chiller module eliminating the need for any master controller which improves redundancy for critical applications.

Built for Service

Other commercial or industrial units are built as throwaway units or are so hard to service that it is easier to just replace the unit. All AIR units are designed and built with the service technician in mind. We are able to do this by take the learning and difficulties that we see in the field and pass that information to our engineering team to enhance our units.

1. Cleanable shell & tube condensers
2. Serviceable compressors for industrial reliability
3. Replaceable filter drier with isolation valves
4. Condenser isolation valves for in-operation service
5. Service clearance required at front of unit only

The ModulAIR Heat Recovery Series delivers significant energy savings by recovering energy for applications where heating and cooling are required. Condenser heat that would otherwise be wasted can now be used for space heating, domestic hot water, or any other heating process. Because of its advanced controls, the ModulAIR can perform as a conventional chiller when cooling is required and switch into heat recovery mode when heating and cooling are both required. For ultimate flexibility, the unit is available with a dual condenser option. This allows users to recover heat when needed or reject the heat through the second condenser when there is no heat load.
