OCAP™ Non-Welded Heat Exchangers

Durable. Dependable. Efficient.

The Open Channel Air Preheater (OCAP) offers a dynamic solution for all of your heat recovery needs. Modular and custom-designed to meet your application, OCAP units are compact and available in both cross flow and counter flow configurations. This modular design offers the most flexible and efficient flow arrangements. It also offers significant improvements in design and operational flexibility, including the freedom to select appropriate materials of construction for each heat transfer zone.


MECS acquired the OCAP technology from North Atlantic Technologies (NAT) in 1999. We are happy to provide quotations for new applications in addition to MECS/NAT replacement units.
