Heat Transfer Fluid for Industrial Laundry Applications
Why use a heat transfer fluid in industrial laundry facilities?
In industrial laundry equipment, fluid-based heat transfer systems are usually employed to transport heat, for example when operating flatwork irons. In this context, thermal fluid systems are preferable to traditional steam-based systems, in that they easily heat up to 230° C compared with the 180° C of steam-based systems.
Moreover, fluid-based flatiron systems operate at a pressure that is approximately 85 times inferior to that required by steam-based systems. Fluid-based systems are therefore preferable, because they reduce health and safety hazards for operators.
Finally, thermal fluid systems reduce common issues in the laundry industry that would be amplified with a steam-based system, such as corrosion, condensate return and steam trap maintenance.
What properties do heat transfer fluids in this application require?
Industrial laundry and flatiron equipment used in the public sector requires the use of heat transfer fluids that can work at the correct temperature for prolonged periods of time. This is especially important for sensitive environments, such as prisons, hospitals and care homes, where washing laundry regularly and at high temperatures is essential to prevent the spread of infection.
As a consequence, heat transfer fluids for industrial laundry applications must have excellent thermal and oxidation stability to operate efficiently at these high temperatures.
