Heat Transfer Fluids

A coolant is a substance that is used to reduce or regulate the temperature of a system. Ideally, a coolant has high thermal capacity, low viscosity, is non-toxic, chemically inert and neither causes nor promotes corrosion of the cooling system. Some applications also require the coolant to be an electrical insulator.

While the term "coolant" is commonly used in automotive and HVAC applications, in industrial processing "heat-transfer fluid" is also used as a technical term more often used in high temperature as well as low-temperature manufacturing applications. With purity, safety and efficiency to consider, it is imperative that you trust the quality of the coolants you use in your business, as well as rely on your chemical distributor for accurate, on-time service, customer support and supply chain expertise.

    Key Considerations for Selecting Heat Transfer Fluids

    Choosing the right heat transfer fluid for closed-loop systems requires careful consideration of several factors:

    1. Thermal Properties: The effectiveness of a heat transfer fluid depends on its thermal conductivity, specific heat capacity, and viscosity. These properties influence how well the fluid transfers heat and operates under varying temperatures.

    2. Freezing and Boiling Points: An ideal heat transfer fluid should have low freezing and high boiling points to function effectively across a wide temperature range, preventing damage from freezing or boiling.

    3. Compatibility: The fluid must be compatible with system materials to avoid corrosion and degradation, which can lead to leaks and system failures.

    4. Health and Safety: Non-toxic and volatile organic compound (VOC)-free fluids are crucial to ensure the safety of occupants and maintenance personnel.

    5. Environmental Impact: Biodegradability and low global warming potential (GWP) are important for reducing environmental footprint.

    6. Sustainability: The production and lifecycle of the heat transfer fluid should align with sustainable practices, helping to ensure minimal environmental impact.

    A stable temperature range in your industrial application is essential when running your operations. Equipment performance and lifetime can be highly dependent on the right choice of heat transfer fluid, customized for your specific needs. Regardless industry, our offering and technical support will help you every step of the way.
