As our team has been on the road for various trade shows, we’ve received great interaction about our new product. People are interested in low-viscosity fluids, but they also want to see it prove out before taking the leap. That’s why we’re excited to share the results of a rigorous, third-party study.
NYSERDA—the New York State Energy Research and Development Authority—is a nationally respected public agency known for advancing clean energy innovation and supporting objective, science-based analysis. Their work is highly regarded among engineers, policymakers, and clean energy professionals across the country. When NYSERDA puts its name on a study, it’s because the findings meet a high standard of technical credibility and practical relevance.
NYSERDA conducted an independent evaluation of the benefits of COREFROST™ compared to traditional antifreeze solutions in ground source heat pump (GSHP) systems. Here is a snapshot of their findings, with emphasis on real-world results.
Note: CORECHEM Inc. has received exclusive U.S. distribution rights to this Kilfrost product, which is now marketed domestically as COREFROST™. The link to the published NYSERDA report can be found at the conclusion of this article.
Superior Freeze Protection
COREFROST™ can effectively reduce pumping energy while maintaining freeze protection down to 15°F, when compared to the energy required to pump propylene glycol with protection down to 20°F. That means:
- More confidence in system reliability during extreme cold
- Greater operational safety margin in variable conditions
Energy Savings: Lower Pumping Power
Because of its lower viscosity, COREFROST™ reduces the energy needed to circulate the fluid:
- Up to 6% annual pumping energy savings when compared to propylene glycol with equivalent freeze protection
- 11–15% savings when both fluids are compared at the same freeze point (20°F)
Improved Heat Transfer = Shorter Boreholes
COREFROST™’s ability to maintain turbulent flow at lower temperatures improves heat transfer efficiency. As a result:
- Borehole lengths could be reduced by as much as 27%, cutting drilling costs
- Designers can plan systems with lower entering water temperatures (EWT), without sacrificing performance
Enhanced System Reliability
Lower viscosity at cold temperatures helps maintain turbulent flow, even in extreme conditions. This:
- Prevents fluid freezing even when temps dip below protection levels
- Avoids costly shutdowns and system failures due to low flow rates or laminar conditions
Safety and Sustainability Built In
Unlike methanol, which is flammable and toxic, COREFROST™:
- Uses food-safe, renewable ingredients
- Is non-toxic and safer for installers and the environment
- Avoids regulatory concerns in states with strict chemical use guidelines
Design Flexibility Without Compromise
COREFROST™ enables geothermal system designers to:
- Use smaller pipes and still maintain efficient flow
- Push design boundaries confidently, knowing performance won’t suffer
- Reduce overall installation and lifetime operating costs
