Hexid Heat Transfer Fluids
Applied Thermal Control supplies a carefully selected range of heat transfer fluids designed to protect cooling equipment, extend serviced life, and ensure safe, efficient performance across diverse applications. Developed for use in recirculating chillers, heat exchangers, and airblast coolers, ATC fluids provide reliable thermal stability while minimising risk of system damage and downtime. Our portfolio includes fluids tailored for different environments - offering protection against freezing, biological growth, and corrosion, while also supporting applications requiring operation at extended high or low temperatures. Each fluid is tested for compatibility with ATC systems to deliver optimal flow, consistent cooling, and long-term reliability. By using the correct heat transfer fluid, customers can: • Optimise performance - ensure accurate temperature control and efficient heat exchange • Protect equipment - prevent scaling, corrosion, microbial contamination • Extend service life - safeguard pumps, seals, and internal components • Operate safely - benefit from formulations designed to reduce risk and support regulatory compliance. ATC heat transfer fluids are available in a variety of specifications to match application needs, with full technical support to guide selection and use.
Chiller Service, Maintenance, and Installation
At Applied Thermal Control, we believe that the performance, safety, and longevity of your cooling systems rely just as much on expert installation and ongoing care as on high-quality equipment. Our end-to-end service and installation solutions are designed to deliver peace of mind from the moment your chiller arrives through every year of its working life. Installation and Commissioning: From the initial site assessment through to integration, testing, and calibration, our certified engineers ensure that your new system is installed with precision. We can manage hose connections, secure fittings, system calibration, and operational checks, so your ATC unit works safely and efficiently from day one. When it's time to upgrade or retire existing equipment, our decommissioning services and UK-wide scrappage scheme make disposal compliant and environmentally responsible. Servicing & Maintenance: Regular, preventative servicing is essential to keeping performance high and avoiding unexpected downtime. ATC offers flexible maintenance contracts (1-3 years) delivered by F-Gas certified engineers, covering emergency support, scheduled service visits, and spares at preferential rates. Whether for ATC chillers or third-party equipment, our global service partner network ensures fast, reliable maintenance wherever you are. Proper installation sets the foundation for optimal performance and safety. Routine maintenance extends equipment lifespan, improves efficiency, and ensures compliance with regulations. ATC's commitment to both means that you benefit from lower running costs, fewer surprises, and better return on your investment.
