Shell & Tube Heat Exchangers
Altex is High Spec Shell & Tube
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.
