​Shell & Tube Heat Exchangers

We’re expensive, but we’re worth it.

Heat exchangers aren’t getting any easier.  Regulations, specifications, and technical requirements are ever growing in scope and complexity and require significant engineering horsepower to transform the documentation into a fabricated shell & tube heat exchanger. 

Altex has over two-dozen professional engineers and technologists across departments and throughout the organization.  We have been designing, building, and servicing shell & tube heat exchangers for over 20-years.
