Air Cooled Heat Exchangers (ACHE)

Answering The Needs Of Our Customers

CUST-O-FAB has been an expert in heat transfer and fabrication since 1972.  Based on the overwhelming demand from our customers to build air coolers, also called fin fans, air heat exchangers, and air coolers, we officially launched our dedicated ACHE product line in 2020.  We offer a full-service approach to our customer’s ACHE needs, utilizing both our dedicated air cooled heat exchanger facility located in the Port of Catoosa, Oklahoma and our on-site service.

Decades of experience in designing, building, and servicing air coolers gives us and our customers a distinct advantage.

Full-Service ACHE Offering

We are combining our extensive fabrication capabilities and on-site field expertise to provide a full-service offering to the industry for air cooler needs. This offering goes through the OEM design and build stage for complete units and can be supported by our field personnel for the on-site work required, from site prep to ACHE installation. 

We also offer on-site and factory retubing, as well as parts supply for ACHE needs. Our approach to an ACHE project is to assign one project manager for either the OEM offering or a combination of OEM fabrication and on-site work—one person to contact and one company to trust for all your ACHE projects.
