Where there’s a mill, there’s a way

04 November 2019

Babcock Wanson has supplied flour millers Whitworth Bros. Ltd. with two TPC thermal fluid heaters for a flour heat treatment process. 

The original thermal fluid heater at the Whitworth Bros site had been installed in 2004 as part of a complete process install project. 

“Support from the other company had been very poor over the years,” explained Alan Boyce, engineering manager at Whitworth Bros. “In August 2018 the heater suffered a catastrophic failure of the heating coils rendering it useless.”  With the incumbent company unable to supply a swift solution, and Whitworth Bros. productivity directly affected, the company turned to Babcock Wanson.
Babcock Wanson’s Thermal Fluid Heating System rental service provided a good solution.  Two ‘plug and play’ TPC 400B thermal fluid heaters were delivered to site and set up by Babcock Wanson’s commissioning engineers.  “The service from Babcock Wanson was excellent the company helped us out when we could not produce, and thermal oil heaters are not readily available to purchase but are made to order,” said Boyce.
Following installation of the rental heaters, Babcock Wanson TPC 600B and TPC 1000B thermal fluid heaters were ordered by Whitworth Bros.  These are now in- situ and are being used to pre-heat filtered air, which is then used as part of the heat treatment process of flour which changes the baking properties for suitability in different food products, such as sauces, batters etc.  “The thermal fluid heaters have performed to our expectations and have proved to be cost effective,” said Boyce.
Thermal fluid heating was selected over other methods for this process due to its lower maintenance requirements, its non-corrosive nature and ability to run at low pressures.
