How Freeze Block Coils Work
- Reduce future maintenance, downtime and coil failure
- Freeze Block™ Valves sense changes in pressure & temperature
- A controlled volume of water is displaced from the coil as it begins to freeze, Freeze Block™ valves then reseat to prevent flooding
- In many cases, eliminates the need for glycol which increases efficiency
- All Cooney Freeze Block Coils come with a minimum 30-month warranty against freeze damage
- Add a Smart Coil System for instant notification of freeze events and a 48-month warranty
- Available for Fluid, Steam and Face & Bypass Coils
Don’t Get Ruptured!
Get Freeze Block™
At temperatures 32°F and below, water can freeze and expand, causing excessive pressures that result in coil damage within a matter of minutes. Consequentially, expensive and time-consuming maintenance, coil repair, downtime, and potentially serious subsequent damage from the thaw and flood often occurs.
System failures frequently happen. Thanks to Freeze Block technology, you can add another layer of protection, should a freeze occur.
HVAC Coils Fail Prematurely due to Freeze Damage
Marriott Downtown Philadelphia
“These air handlers were a constant nuisance for the client; coils were rupturing every year. Since installing Cooney Freeze Block in 2011 we have yet to see a failure on any coils that were replaced by Herman Goldner Co., Inc. This product really does work.”
-Rob Scanlan of Herman Goldner / Account Rep for Marriott Downtown Philadelphia
“They [Lancaster Rehab Hospital] called about a coil rupture on Unit #1. When they got there we found out the Freeze Block opened and saved this coil. First experience with this and I am thrilled with the results. The freeze stat failed to operate.”

“Water can freeze and rupture a coil in minutes, often faster than you can respond to a freeze stat alarm, the Cooney Coil helps eliminate this issue, as well as potential flooding and the associated damage.”
-Bill Artowski Vice President of Sales at Tozour Energy Systems

“We originally thought the coils ruptured when we found a patch of ice on the floor of the air handler. We were very happy that when our system failed, our coils did not rupture. Instead, the relief valves had discharged and when we thawed the coils they went back into operation with no leaks. We are happy that we went the extra mile and protected our HVAC coils with the Freeze Block technology. This event made believers out of us.”
-Roy Stein of University of Pennsylvania
“This product did what we hoped by protecting our steam coils from rupturing and kept the heat on as a result.”
-Jim Farrell of Delaware Engineering
