Heating and Cooling Coils

Heavy-duty heat exchangers for harsh environments or difficult to access locations

Robust Heating Coils & Cooling Coils

Turnbull & Scott custom design and manufacture extended surface, finned, plate-fin and plain tube crossflow type heat exchangers (also known as 'coils') for the broadest range of industrial heating, drying, dry cooling and heat recovery applications. We have the solution for you depending on your application, including steam heat exchangers, water, or more.

Robust, Heavy Duty Coils for OEMs & End Users

Our robust heat exchanger coils and batteries are renowned for their thermal performance, reliability and longevity. They can be found in the most challenging environments.

We supply end-user clients for both new installation and refurbishment projects and also OEM clients who integrate our high-grade coils into their heating, drying, cooling & heat recovery equipment.

Proprietary Cu Al Plate-fin Coil Heat Exchanger Design

Central to the robustness of T&S plate-fin coils is the unique steel encased tube header design which incorporates high grade thick walled copper tubes and BS EH1501-161-430 (EN10028) boilerplate and interference fit steel ferrules.

This unique design ensures integrity at high temperature and pressure and negates the requirement of traditional return bends which have inherent fragility and are notoriously prone to frost damage.

Extend your Plant Life

With over 70 years experience in heat exchanger design and manufacture, Turnbull & Scott is exceptionally well placed to test and determine the root cause of heat exchanger failures.

Plain tube, extended surface as well as shell & tube heat exchanger repairs undertaken.

The company can offer on-site visits and factory testing to determine whether repairs are possible and to undertake repairs and refurbishment of existing coils and headers where feasible or supply retrofit of replacement coils and headers where required.
