GEO-30

Propylene glycol fluid for geothermal systems

GEO‑30 is a glycol‑based heat transfer fluid specifically developed for geothermal systems and ground source heat pumps. It ensures reliable heat transfer and freeze protection in closed loop systems operating under varying ground temperatures. The formulation supports long‑term system stability, prevents corrosion and minimizes performance loss in geothermal installations.

Custom glycol concentrations are available depending on required freeze protection levels and system design, and our team is available to advise you on the best options for your application.

Optimized for geothermal and ground‑source systems

Geothermal systems operate in closed underground loops where fluid stability, controlled viscosity and dependable heat transfer are critical for system efficiency. GEO‑30 offers optimized viscosity and thermal conductivity, enabling efficient energy exchange between the ground and the heat pump installation.

The formulation includes a corrosion inhibitor package that protects system components against corrosion and mineral deposits. This protection contributes to reliable long‑term operation of geothermal circuits and helps extend the service life of pipes, heat exchangers and pumps.

Environmentally safer choice for subsurface applications

Because GEO‑30 is based on propylene glycol, it provides an environmentally safer alternative for subsurface energy systems and installations where ecological responsibility is a key consideration. This makes the fluid particularly suitable for renewable energy projects and underground energy storage systems.
