Heat Transfer Fluid - Global Heat Transfer

Global Heat Transfer supplies premium thermal oils for a range of sectors including solar, pharmaceutical processing, food and beverage processing, industrial manufacturing, composites manufacturing such as Medium Density Fibreboard (MDF), carbon fibre and resins, chemical processing, as well as the plastic, polymer and styrene industries. As experts in thermal fluids and heat transfer systems, we can help you choose the correct fluid for your application.

Choosing a thermal oil

One of the first considerations should be thermal fluid temperature. For example, thermal oils for solar applications must provide high temperature stability to avoid fluid degradation at high operating temperatures. Degradation can reduce overall fluid life and heat transfer system efficiency. It can also impact system safety and increase maintenance costs. You should also consider whether the chosen fluid is safe for your application. In food and beverage processing, a H1 or HT1 certified food grade thermal oil should be used as they are non-toxic. This regulation also applies for thermal oils used in pharmaceutical processing to ensure consumer safety. Select your application here to determine the requirements of your thermal oil.

Once you’ve chosen the correct thermal oil, it’s important to maintain it. Over time, the molecules in thermal oil will break down. This is a process called thermal cracking. This creates volatile light ends and heavy ends in the oil, which can cause the fluid to degrade. It also produces carbon molecules that can stick to the pipes, which reduces the efficiency of the system.

Thermal fluid analysis

It’s hard to know whether thermal oil has degraded without regular representative thermal fluid analysis. In fact, you may only notice oil degradation once it begins to impact production, for example, when a food product is not cooked consistently, or chemicals are not blending properly.

Thermal oil regulations

Failure to carry out regular thermal fluid analysis will not only impact production, it also puts you at risk of noncompliance against The Dangerous Substances and Explosive Atmospheres Regulations (DSEAR) of 2002 and the Explosive Atmosphere Directive (ATEX 137). These standards set the minimum requirements for protection against risks of fire, explosions and similar events arising from dangerous substances in the workplace.

Preventative maintenance 

Global Heat Transfer can help manage your thermal oil and keep production running with our proactive condition-based fluid lifecycle management plan, Thermocare. There are three packages to choose from — Essential maintenance, Optimum lifecycle maintenance and Ultimate lifecycle maintenance. Our Essential maintenance plan acts as an early warning system to help manage your heat transfer fluid and maintain production. With Optimum, you’ll receive a proactive condition-based approach to managing your fluid. Finally, with Ultimate, Global Heat Transfer will take complete ownership of the maintenance of your heat transfer fluid for a fixed price.   Find out more about Thermocare here.
