25,000 BTU/hr — the largest chiller in the standard range, built for commercial-scale plunge use and multi-tub setups.
Penguin Chillers has been building water chilling equipment in Knoxville, Tennessee since long before cold plunging went mainstream. The 2.5 HP is what a gym, recovery studio or multi-tub facility runs when a 1 HP unit cannot keep up. Choose the titanium coil for normal treated water, or the 316 stainless shell and coil for higher pressure systems.
Electrical — this one is different
Unlike every other chiller in this range, the 2.5 HP runs on 208–240V single phase, 14.7A, 3,200W, through a NEMA 6-30 style receptacle. This is not a household outlet. You will need an electrician to run a dedicated 240V circuit before installation. Please confirm this is in place before ordering — a unit that cannot be plugged in is still subject to our return terms.
Read this before you buy — what is not included

Delivery
