About HVAC & Geothermal

Glycol-based coolants, antifreeze, and heat transfer fluids for HVAC systems, geothermal loops, and chiller applications.

Frequently Asked Questions

How do I choose between ethylene glycol and propylene glycol?

Choose the fluid specified for the system and application. Evaluate freeze protection, heat-transfer performance, equipment compatibility, applicable safety requirements, and whether the system has food-contact or other restricted-use considerations.

What glycol concentration should an HVAC or geothermal loop use?

The required concentration depends on the design freeze-protection target, operating temperatures, system water quality, and equipment requirements. Establish the concentration from the engineered design and verify it with the responsible operator or contractor.

Why does water quality matter in a glycol system?

Water quality can affect corrosion control, scale formation, and inhibitor performance. Use the water quality and fluid preparation requirements specified for the system rather than assuming all water sources are interchangeable.

What should be checked before adding or changing coolant?

Confirm the existing fluid type, inhibitor chemistry, materials compatibility, target concentration, and equipment manufacturer guidance. Review the product Safety Data Sheet and do not mix fluids without documented compatibility.
