Enviro-Kool High Performance Fluid
For Heat Transfer Applications

Enviro-Kool, a new high performance fluid from Clearwater, Inc., is designed for secondary cooling systems, process cooling, and other heat transfer applications at operating temperatures of -70°F to 300°F. The high thermal conductivity enhances heat transfer efficiency compared to glycol/water systems, effectively increasing the system capacity. Enviro-Kool's low viscosity at low temperatures reduces pumping requirements, which reduces energy costs and can allow the use of smaller pumps in newly installed systems or retrofitted applications.

Enviro-Kool is a non-toxic and non-flammable ready to use fluid that can be used as a direct replacement for glycols without any modification to equipment. A specially designed inhibitor package assures the protection and long life of metal components, and the fluid complies with the ASTM D-1384 standard. Enviro-Kool is compatible with all commonly used elastomers in its operating temperature range.

Enviro-Kool can also be used for winterization of HVAC equipment. Its biostatic nature prevents bacterial growth and the associated odors, and the use of Enviro-Kool should simplify recommissioning procedures by not requiring a separate disinfection step.

The Benefits of Enviro-Kool

• Increased Heat Transfer Efficiency
• Reduced Power Requirements
• Low Toxicity
• Biodegradable
• High Compatibility with System Materials
• No Emissions

Properties Important to Heat Transfer

The table below lists the values of commonly used ethylene glycol and propylene glycol fluids, along with those of a standard Enviro-Kool system. The parameters are listed in decreasing importance to heat transfer.

Health, Safety and the Environment

Toxicity toward humans and other species is important in protecting the environment in case of an unanticipated release of any line heater fluid. Enviro-Kool has a low toxicity toward mammals and fish, and is not nearly as dangerous as ethylene glycol to humans. In addition, if Enviro-Kool is released to the environment, it biodegrades rapidly, with much less oxygen demand than the glycols, as shown in the following table. Low oxygen demand means little chance of fish kill in rivers and streams through oxygen deprivation.
