Pricing for the Deep Freeze 20 Ton Chiller
Pricing for this unit depends on two things: the tonnage (which you've already selected at 20 Ton) and the voltage configuration you need.
Three-phase 480V is typically the most cost-effective option for facilities that have it available — it allows smaller, more efficient electrical components than 208–240V three-phase configurations.
Ordering Guide
All voltage variants share the same 127,500 BTU/hr @ 27.5°F / 70°F cooling capacity and 10°F to 45°F fluid range. Choose the configuration that matches your facility's available power.

Need Different Specs?
These are our in-stock units — but we design and build custom chillers every day. Different capacity, temperature range, voltage, refrigerant, or footprint? Our engineering team can make it happen.
Don't Forget the Glycol
All North Slope chillers require propylene glycol to operate. If you don't already have glycol on hand, we carry a 50/50 premixed solution that's ready to pour — no mixing required.
