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.
Big and Ugly
Large-diameter, high-pressure, heavy, challenging metallurgy, and/or high-spec heat exchangers – this is our bread and butter.
To chew through this type of work you need serious engineering and technical horsepower, which is why Altex has over a dozen Professional Engineers in-house!
You also need technical experts throughout the organization to drive projects successfully.

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.
