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 hot water, chilled water and steam 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.

TESTIMONIALS
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
Penn Medicine
“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.”
Scott Lankfordof Spangler & Boyer Mechanical, Inc.
Tozour Energy Systems
“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
University of Pennsylvania
“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

Frequently Asked Questions
What makes Freeze Block Technology Unique?
Cooney Freeze Block was developed and patented by Cooney Technologies over a period of years. Unlike obsolete technologies on the market, it responds to both of the following freezing scenarios: freezing from the outside in and freezing from the inside out. Our solution has been proven to respond to both pressure and temperature threats simultaneously.
How much maintenance do Freeze Block coils require?
Once a Freeze Block coil has been installed onto your existing HVAC units, maintenance is minimal. Because Freeze Block contains very few moving parts, and no complex or motorized valves, it requires little or no maintenance.
Has this technology been deployed?
Cooney Freeze Block Technology is installed in HVAC systems all over the continent.
From Ford Motor Comany to GlaxoSmithKline to The White House our technology has found its way into a large number of HVAC systems.
We have thousands of active installations with 100% success.
Can I retrofit Freeze Block
Infield installation of this technology would be expensive and difficult due to the amount of brazing required and the general lack of access to existing coils. At this time, Freeze Block™ Technology cannot be retrofitted onto existing coils.
What does the Freeze Block Warranty Cover?
All Cooney Freeze Block™ Coils are backed by a 30-month warranty against freeze damage. If you add the Smart Coil freeze alert system, we will extend that to 48-months protection against freeze damage!

Why Do HVAC Coils Freeze?
Stay one step ahead of frozen temperatures in the winter and prevent the need for HVAC coil replacement with our patented Freeze Block coils. Why commercial coils freeze is a complex question, but the result can be detrimental to your building. Common reasons why steam or fluid coils freeze include: controls failure, plant failure, power outage, human error, and improperly drained coils. Our Cooney coil freeze protection coils ensure that your fluid or steam coil last many winters with minimal maintenance required.
At Cooney Engineered Solutions, we understand how costly frozen HVAC coils can be to replace. Our Freeze Block technology is the perfect solution for protecting your coils from rupture at freezing temperatures. Our Freeze Block provides the ultimate freeze protection and eliminates any worries or stress associated with burst coils, potential flooding, and downtime. Our technology is as freeze-proof as possible, preventing your HVAC coils and heating coils from needing costly repairs.
Make It a Smart Coil
To prevent ruptured coils, Freeze Block automatically alerts your building maintenance team when it detects freezing conditions and communicates with the BAS to disengage specific systems. With fast reporting and instant coil protection, you’ll be able to diagnose the root cause of freezing. Cooney Freeze Block coils, our revolutionary alternative to coil freeze plugs, keep your building operational even in frozen temperatures.
Frozen HVAC Coils Are a Thing of the Past
Our Freeze Block works with all types of fluid and steam coils. Backed by an impressive 30-month freeze protection guarantee, Cooney Coils are as close to freeze-proof as possible and can be constructed using the material that best fits your system. Our Cooney Coil technology will prevent rupture in freezing conditions so you can identify the cause of the freeze and return to normal operations as quickly as possible.
