In the world of hydronic and heat transfer systems, fluid choice matters. Whether you’re designing a geothermal loop, chiller, or HVAC system, your heat transfer fluid directly impacts efficiency, reliability, and total cost of ownership.
For nearly 100 years, ethylene glycol has been a go-to standard for heat transfer systems. But today’s demands for greater sustainability, efficiency, and safety require a smarter approach. That’s where COREFROST™ ALV comes in: our Advanced Low Viscosity fluid, powered by Kilfrost technology. Designed for modern hydronic systems, COREFROST™ ALV delivers superior performance, energy savings, safety, and environmental responsibility, when compared to traditional ethylene glycol.
Lower Viscosity, Higher Efficiency
COREFROST™ ALV is a glycerin-based, low-viscosity fluid that stays remarkably thin and free-flowing, even in freezing temperatures. Traditional ethylene glycol thickens as temperatures drop, forcing pumps to work harder and increasing energy consumption.
Safe, Sustainable, and Non-Toxic
Ethylene glycol has long been valued for its performance, but it comes with one major drawback: toxicity. It is highly poisonous to humans, animals, and aquatic life, requiring strict handling and disposal procedures.
COREFROST™ ALV eliminates those concerns. It’s made from renewable, food-safe ingredients; and it’s available in a food processing version (COREFROST™ ALV+), specifically designed for applications where incidental food contact could occur.
Proven Savings and Real-World Results
Real-world testing has shown that COREFROST™ ALV doesn’t just perform better on paper – it delivers measurable savings in actual systems. In independent NYSERDA field studies comparing COREFROST to traditional glycol fluids, systems using COREFROST used up to 6% less pumping energy per year, while maintaining reliable freeze protection down to about 15°F. When both fluids were tested at the same freeze point, COREFROST achieved even greater efficiency – saving 11–15% more energy overall.
Beyond top-tier performance, COREFROST™ ALV+ is NSF HT1 certified for incidental food contact, making it safe for use around people, animals, and the environment. It’s a non-toxic, eco-friendly fluid that delivers reliable protection in geothermal, snow melt, and industrial refrigeration systems. Many companies are making the switch from Ethylene Glycol to Propylene Glycol, but the change often comes with hidden costs. Because Propylene Glycol doesn’t perform as efficiently, it can require expensive upgrades to pumps, heat exchangers, and piping. That’s where COREFROST ALV comes in. Designed for superior performance, COREFROST ALV eliminates the need for costly equipment upgrades – while outperforming both Ethylene and Propylene Glycol, especially in low-temperature conditions.
