Why us
Why cold plunge practitioners trust FrigePath
Temperature performance
Minimum temperature actually reached in a stated tub volume at a stated ambient, taken from owner reports and published performance data rather than the headline rating, with the gap flagged when the two disagree.
Sizing and compatibility
A half-horsepower chiller that works in an 80-gallon indoor tub will not hold temperature in a 110-gallon outdoor setup in summer. We match products to real use cases, not the smallest tub on the spec sheet.
Build and material quality
Titanium versus copper heat exchangers, 600D fabric versus single-layer PVC, rotomolded versus blow-molded plastic. Material grade is the durability signal that marketing copy obscures.
