Mainstream - The Leaders in Custom Air Handling

CTM Series Custom Air Handlers

Our CTM Series Custom Air Handling Unit delivers years of reliable, trouble-free performance in situations where large volumes of precisely conditioned air are critical. There is virtually no limit to the available options since each unit is manufactured specifically for a particular application

The CTM Series Unit can be furnished as a complete factory-fabricated unit or in modules for field assembly. Accessories such as variable frequency drives, vapor-proof service lighting and convenience receptacles can be factory installed, reducing installation time in the field and ensuring correct functionality at startup.

CTM Aluminum Air Handling Unit

The CTM Aluminum Air Handling Unit features an all-aluminum, thermally-broken casing (no thru-metal) for optimum performance. The foam injected panels provide structural integrity and a high R-value. Aluminum diamond-tread floors, thermally broken access doors and frames, and heavy-duty components produce a unit that is in a class of its own.
