CI H-150 Non-Toxic Glycol Solution −33°C
Moderate-protection propylene glycol heat transfer fluid for closed-loop systems requiring non-toxic chemistry.
CI H-150 is an inhibited propylene glycol antifreeze and heat transfer fluid formulated for freeze protection to −33°C. It sits in the middle of the non-toxic glycol line: stronger than a dilute field blend, but not pushed to the deeper-freeze concentrations used where extreme low-temperature protection is required. The inhibitor package provides the corrosion protection untreated glycol cannot. Clear, colourless, and odourless, H-150 is well suited for heating systems, recreational vehicles, and other closed-loop applications where −33°C protection is the right answer and anything colder would be unnecessary overbuild.

Operational Notes
• H-150 is the moderate-protection propylene glycol in the line — stronger than a light field blend, but not built for severe low-temperature duty
• Strong fit for heating systems and recreational vehicles where −33°C protection reflects the actual winter exposure
• The inhibitor package is the reason this is a system fluid rather than just glycol and water; untreated glycol does not protect against corrosion on its own
• Compared with H-55, H-150 is the less concentrated non-toxic option for systems that do not need deep-freeze protection
• Clear, colourless, odourless fluid profile supports clean use in enclosed and equipment-adjacent service environments
• Commercially, this is the right answer when the buyer wants non-toxic glycol and moderate protection — not a colder, heavier solution than the job requires
Practical Fit
CI H-150 is the moderate-protection non-toxic glycol in the line: a propylene glycol solution for closed-loop systems that need real freeze protection and corrosion resistance, but do not need to be pushed into deep-freeze concentrations to get there.
