Hydronic snow-melt glycol that protects the slab and the loop.
Hydronic snow-melt loops embedded in pavement run on glycol that has to survive deep cold and protect buried metal for years. Burst protection sizing and inhibitor longevity are everything.
Talk to a SpecialistWhat you're up against
- Embedded loops are expensive and disruptive to repair, so get the protection right once
- Deep-cold burst protection has to be sized to the local design temperature
- Mixed-metal manifolds need durable corrosion protection
A snow-melt loop is poured into the slab. You protect it once, and it stays protected for years. PGHD gives embedded hydronic systems deep-cold freeze and burst protection with a long design life and full ASTM documentation. Use our calculator to size the concentration to your local design temperature.
The spec
PGHD delivers freeze and burst protection to deep-cold design temperatures with a ~15-year design life and ASTM D1384/D8039/D8040 compliance. PGAL is available where aluminum manifolds require phosphate-free chemistry. Size it with our freeze/burst calculator.
