Prevent Freezing Valves with CATCO Catalyic Heaters

The primary issue that leads to freezing valves is pressure drops in the gas flowing through them. All gas carries some element of moisture in it. This means that when your set-up includes significant pressure drops, you need to be aware of the potential for freezing valves.

Valve Bodies are Vulnerable

A spot particularly vulnerable to freezing is your control valve body. When you have a large pressure cut across a valve and it’s already cold outside, you’re going to run into solidification issues.

In fact, for every 100 psi cut across a valve, you get a temperature drop of 7 degrees. Frozen instruments can lead to significant production downtime (and accompanying frustration). And while freezing ambient temperatures don’t help the situation, freezing valves can happen anytime during the year.

How to Prevent Freezing Valves

To prevent freezing, some operators use heat tape wrapped around insulation. This can be an inefficient and messy way to prevent freezing. If you need to repair your control valve, you will have to cut the tape and insulation away to get access to the valve, and then replace it when you are finished.

A good alternative to this option is using a CATCO Catalytic Heater. These heaters use supply gas to provide a flameless heat that keeps the valve warm, and feature a hinge door with two clips on the top to provide operators with easy access for maintenance or repair.

  • With no moving parts, the heaters will operate indefinitely with a clean fuel supply.
  • The surface of the heater reaches a maximum of 700°F, approved for hazardous environments.
  • You can focus the CATCO’s radiant heat on the valve or pipeline, whichever areas most likely to freeze. This increases efficiency as you can use smaller heaters, lowering initial costs and fuel consumption.
  • CATCO heaters are custom designed for Kimray valves.

CATCO Catalytic Heaters provide a cost-effective solution to freezing valves. Install them on your site, and when pressures drop, you can rest assured your valves are warm and flowing.
