Kilfrost GEO is an advanced low viscosity heat transfer fluid specifically engineered to enhance the performance and safety of closed-loop ground and water source heat pumps. Designed for renewable energy applications like Ground Source Heat Pumps (GSHP), Kilfrost GEO reduces system pressure drops, lowers pumping energy and costs, and improves overall efficiency.By replacing traditional fluids like mono ethylene glycol (MEG) or mono propylene glycol (MPG), customers will see immediate improvements in system performance, leading to long-term energy savings.
Enhanced performance and safety for heat pump systems
A Ground Source Heat Pump (GSHP) system extracts heat from the earth through a network of pipes buried underground. These pipes, filled with a heat transfer fluid, absorb naturally occurring heat, which is then extracted by a heat exchanger and transferred into the heating system. Kilfrost GEO’s low viscosity ensures that the fluid flows efficiently, even in cold temperatures, and reduces the energy needed to pump the fluid through the system – so lowers operational costs.
Similarly, Kilfrost GEO can be used in water source heat pumps, delivering the same benefits.
The fluid’s ability to maintain low viscosity even in colder temperatures means that the required depth of ground loops can be reduced, which can significantly lower construction and installation costs. This makes it a cost-effective solution for new and existing systems.
An eco-friendly and sustainable low viscosity heat transfer fluid
Kilfrost GEO is non-toxic, bio-derived, and classified as non-hazardous according to CLP/REACH standards, ensuring minimal environmental impact. Whereas some alternatives contain toxic chemicals that pose risks to the environment and wildlife if released. Compared to traditionally used glycol and ethanol-based products, GEO is rapidly biodegradable with a significantly lower Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD). This means if GEO was unintentionally released into the environment, its impact would be greatly reduced in comparison to a leak with MPG or MEG. So, whether used in residential or commercial heat pump systems, Kilfrost GEO helps reduce the environmental footprint of renewable energy applications and is less harmful to the environment than traditional products.
