Steam Boiler Plant Solutions

High Efficiency, Low NOx Boilers

Our flagship products have been developed to comply with both current UK/EU legislation and expected future regulations, be more efficient and emit lower NOx.

Building on the success of our famous Wee Chieftain and Thermax Steam Boilers, we have developed the ST28, ST37 and ST32. These high output, high efficiency boilers are supported by the ST23 and ST36 which have been specially developed as more cost efficient options for smaller volume applications.

Providing maximised efficiency and reducing fuel usage, Cochran economisers are available for every new boiler, as well as being a cost-effective retrofit option for existing systems.

From a single boiler, to a turnkey project-managed multiple boiler installation, Cochran delivers worldwide. Every installation is precisely engineered to individual clients needs, from fully packaged industrial steam systems, ready to run, or alternatively a boiler with ancillaries on a supply and commission only basis.

Fired and unfired heat recovery boilers for power generation systems are a speciality. All Cochran boilers can be provided with the latest microprocessor control, monitoring and sequencing systems, which can be extended to monitor plant room ancillary supplies and services.
