MAS can help get you design ERVs that land between standard and custom. Historically we have a high success rate with units over 10,000CFM.
We're good at optimizing dimensions, and we have several design tricks to accomplish this. Every design is a little different, and we configure the selection file for you!

Indoor Side-by-Side
Up to 60,000 CFM
Uncommon configuration for standard manufacturers (at higher CFM)
Effective for lower height applications
Single-side access available
Height limitations drove this design, as a wheel would not fit. The flexibility of the stacked Core arrangement saved length and fit the space.

40,000 CFM DOAS
This design utilizes our Split Core Design. Because enthalpy plates ship in pieces, we don't need a full width heat exchanger section. This allows us to get larger capacities, and makes rigging a lot easier.
Wheels cannot be split!

This image is an example of a "full width" heat exchanger module that was split down the middle. They mate together in field and function as if it was a single full width piece!
Indoor Stacked
Up to 60,000 CFM
Much more flexibility than other standard manufacturers' stacked capabilities
Effective for lower width applications
Utilize variable height tunnels to combat competition

30,000 CFM
Partial OA (15,500 CFM)
The supply air tunnel required 80"H (coil face velocity). The tunnel above it only has filters so we can angle them, requiring only 42"H.
We always use the most effective combination of aspect ratio to shrink unit dimensions. This is zero special, and actually a configuration in your selection software!

44,000 CFM DOAS Dual Wheel
We can utilize width, and our custom configuration to make dual wheel units!

7,000 CFM DOAS
Wheel and plate re-heat
7,000 is a little low on the CFM scale, but if you absolutely need a low footprint unit, we can help. We will not be the cheapest option, but we will be the most compact.
