FREEZE-FIGHTER RTU-PG35 is ideal for water-based systems requiring maximum freeze and corrosion protection without the risk of environmental contamination.

  • Closed Loop Solar Systems
  • Hydronic HVAC Systems
  • Potable Water Lines
  • Sprinkler Systems

FREEZE-FIGHTER RTU-PG35 is a pre-blend to allow for direct replacement of water in the system with equal amounts of FREEZE-FIGHTER RTU-PG35 for burst protection down to -60°F (-51°C).  The direct replacement of water with anti-freeze, without having to measure or calculate the amount of anti-freeze needed, provides for an error free method to protect the system.  FREEZE-FIGHTER RTU-PG35 can also be diluted to offer higher freeze points and burst protection in warmer climates (see freeze and burst protection chart).

Lubricates pumps, valves and moving parts. Will not harm plastic or rubber seals, o-rings, or gaskets.
