Tube Heat Exchangers

For the past decade Valutech has been working closely with Doyle & Roth Manufacturing Co., one of the "old-timers" in the heat transfer industry. Over the years we have supplied custom designed shell and tube heat exchangers for a wide range of industries and applications.

We have successfully met the process equipment and stringent heat transfer demands of the following industries:

• Chemical
• Petrochemical
• Pulp and Paper
• Food
• Power Utility
• Pharmaceutical

With a fabrication facility extending to 360,000 sq. ft., equipped with state of the art fabrication equipment, and Code qualified welders with experience in carbon steel, low and high alloy steel, nickel and nickel alloys, copper, copper alloys, hastelloy, titanium and stainless steel, Doyle & Roth offers a wide variety of tube heat exchangers.

Applications
Doyle & Roth heat exchangers have been used as vent condensers for the pharmacetical industry, as a condenser for nuclear reactors, and feed and reactor heaters fo the petrochemical industry. Some recent interesting projects of shell and tube heat exchangers executed by Valutech / Doyle & Roth include:

Petrochemical Industry:

• Reactor Condenser
• Feed Preheater
