DOWCAL™ Heat Transfer Fluid

DOWCAL™ is a series of high-performance, inhibited glycol-based heat transfer fluids developed by Dow Chemical Company, designed for low-temperature and freeze protection applications. The primary formulations in the DOWCAL range propylene glycol based DOWCAL™ N, DOWCAL™ 200, DOWCAL™ 200E, DOWCAL™ pGEO and several ethylene glycol-based fluids: DOWCAL 100, DOWCAL 100E, and DOWCAL eGEO. Each product offers distinct advantages for various industrial and commercial applications.

DOWCAL™ N is a propylene glycol-based heat transfer fluid, commonly used in applications where low toxicity and environmental friendliness are essential. It is particularly suitable for use in food and beverage processing, pharmaceutical industries, and other scenarios where potential contact with products is a concern. It offers low toxicity, freeze protection, corrosion inhibition and thermal stability. Also, from the propylene glycol-based heat transfer fluid range, DOWCAL™ 200 specifically designed for application that demand high levels of thermal efficiency and stability and it provides superior heat transfer, low viscosity, comprehensive freeze protection and advanced corrosion inhibition. At the same time, DOWCAL™ 200E heat transfer fluid is specifically formulated for extended temperature range applications, offers enhanced thermal stability and performance under fluctuating temperature. Moreover DOWCAL™ pGEO is the propylene glycol specifically formulated for geothermal applications, where efficient heat transfer and long term stability are paramount.

From the ethylene glycol heat transfer fluid portfolio, DOW offers DOWCAL™ 100 which is designed for various industrial applications and highly recommended to be used in heating applications such as data centers, photo-voltaic inverters, wind turbines, heat and electronic systems and components, snow melting systems, etc. DOWCAL™ 100E on the other hand, exhibits lower viscosity and it is free of Borate, and it is more suitable to operating efficiently over an extended temperature range, being better applicable on applications where higher temperatures or wider temperature differentials are encountered. Moreover DOWCAL™ eGEO is the ethylene glycol specifically formulated for geothermal applications, where efficient heat transfer and long term stability are primordial.

DOWCAL™ heat transfer fluids are suitable for several applications, including:

HVAC systems in residential, commercial and industrial buildings.
Refrigeration systems for supermarkets, cold storage facilities, food processing plants and ice rinks.
Solar energy systems for heating water and generating electricity.
Geothermal heat pump systems for heating and cooling buildings.

Medical equipment such as MRI machines, CT scanners and laser systems for thermal management
Greenhouse heating and cooling systems to regulate temperatures for optimal plant growth and productivity.
Waste heat recovery systems to capture waste heat from industrial processes for energy generation
Electronics cooling including computers, telecommunication equipment and power electronics to prevent overheating and ensure device reliability.

Temperature regulation stability: Maintaining precise temperature control across different processes.

Freeze Protection: Systems can be damaged by freezing temperatures, leading to burst pipes and equipment failure.

Corrosion inhibition: Corrosion of metal components in thermal systems can lead to leaks, reduced efficiency, and costly repairs.

Thermal efficiency: Inefficient heat transfer can lead to higher energy consumption and operational costs.

Environmental and safety concerns: Many heat transfer fluids pose environmental hazards and safety risks if they leak or are improperly disposed of.

Thermal degradation and fluid longevity: Thermal fluids can degrade over time, losing their effectiveness and requiring frequent replacement.

Maintenance and operational downtime: Frequent maintenance due to corrosion, scaling, or fluid degradation can lead to operational downtime and increased costs.
