Thermal fluid systems are a standard requirement for new facilities and many existing food and beverage processing facilities are upgrading due to the need for precise temperature control. Food and beverage processing requires heat transfer oils that are HT-1 certified for use in these applications and are non-toxic — these usually come in the form of mineral oils.
Heat transfer oils are used for batch processing of pharmaceutical products. Heat transfer fluids with broad operating temperature ranges are necessary because chemical reactions take place at high temperatures and crystallisation occurs at lower temperatures, which is required to make the final product.
Heat transfer oil for chemical processing
Thermal oil is used in chemical processing operations for indirect heating of process liquids and polymers, single-fluid batch processing, pipeline tracing, energy recovery, low pressure cogeneration, drying and heating of bulk materials and gas processing. All chemical processes have operating parameters specific to the application that guide the selection of the most suitable heat transfer oil.
Plastic, polymer and styrene
Plastic, polymer and styrene production uses heat transfer equipment that often requires a broad temperature range in operation. Heat transfer oils provide the high temperature thermal stability necessary to avoid fluid premature degradation at high operating temperatures.
Wood Processing in the construction industry requires a variety of engineered materials for house building and other applications, such as plywood, panelling, oriented strand board (OSB) and medium density fibreboard (MDF). The process of wood manufacturing requires enormous quantities of heat, so heat transfer fluids play an important role
Metal finishing refers to a broad range of industrial processes that alter the metallic surface of a manufactured item to achieve a certain characteristic, such as improved chemical resistance or electrical conductivity. These processes are highly common in the automotive, electronics, telecommunications, heavy machinery and aerospace industries. Metal finishing is essential to extend the lifespan of many products, which would otherwise be damaged by corrosion, leading to a high turnover of many industrial and household equipment. This would negatively impact the economy and the environment.
Industrial heating and cooling processes include laundries, asphalt plants and marine heating applications, as well as the manufacture of engineered wood for use in housing and construction. Examples of this type of manufacturing are medium density fibre (MDF), panelling and plywood along with other speciality wood-based building products. The wood manufacturing process uses compressed strips of wood bonded with wax and resin adhesives that is heat pressed in a thermal fluid system. The heat from the system cures the wood and adhesive by heat activation at high temperatures. The HTO is a vital part of the process because safety, maintenance and output are vital considerations.
HTO in marine applications are an important aspect because safety and maintenance are vital in large applications that are difficult to monitor. Global Heat Transfer’s technical support team provides on-site and remote support for engineers managing heat transfer oil and heat transfer systems in these remote environments.
Concentrated solar power and thermal storage
Concentrated solar power (CSP) plants require heat transfer oils that are designed to work to the correct temperature for prolonged periods. Heat transfer fluids are used in CSP or solar energy generation and solar thermal storage.
Nearly every step of biofuel production requires efficient heating of product. Heat transfer fluids ensure high quality product output in all applications. The most common types of biofuels are ethanol, biodiesel and fuels produced by gasification of biomass.
Oil and gas
Heat transfer oil systems are central to the processing of oil and gas products. Initial production, transport, refining and recycling all require the use of heat transfer fluids. Offshore platforms use liquid phase heat transfer oil to heat reboilers and columns for the distillation of oil and oil-based products. Companies that reprocess and recycle used oils use heat transfer oil in very high temperature distillation facilities. Pumping stations placed along oil pipelines use heat transfer systems to help control the viscosity of the product moving through the line.
Heat transfer systems are used to heat flatwork irons and offer greater productivity per unit of floor space. With heat transfer fluid-based systems, corrosion, condensate return and steam trap maintenance are eliminated and there is no water treatment of discharge problem. One of the key benefits of a thermal oil-based system is reduced operating costs, which is a result of improved system efficiency. While steam systems generally operate to 350 °F, heat transfer oil systems can easily provide up to 450°F.
Bulk terminals used to store and process asphalt (or bitumen) use heat transfer systems to maintain asphalt at specific temperatures. Plants that use asphalt as a raw material to manufacture roofing material require heat transfer systems for heating the storage facility of asphalt and barges. These are used to maintain fluidity of their material with an on-board heat transfer system.
