Prevent Freeze Damaged HVAC Coils

Stop worrying about frozen HVAC coils!

Freeze Block Coils are designed to prevent freeze-damaged coils. Available for fluid, steam, and face and bypass coils for new air handlers and replacement coils.

How Freeze Block Coils Work

 
Cooney Freeze Block Logo

 

  • Dramatically reduce future maintenance, downtime and coil failure
  • Freeze Block Valves sense changes in both pressure and temperature
  • The valves discharge a controlled volume of water as a coil begins to freeze 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
  • Add a Smart Coil System and receive 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.

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!
