Freeze Prevention for Control Valves
Catco keeps control valves working. Any application, any size, anywhere.
No matter the application, whether it’s pressure reducing, back pressure, dump, or anything in between, Catco has a solution to prevent freezing from shutting you down.
Heated Enclosure Packages
The most popular (and usually most effective) way to prevent freezing in control valves is with a Catco Heated Enclosure Package. A stainless steel enclosure houses a catalytic heater that directs safe, flameless, infrared heat at the body of the regulator. Simplicity and reliability have made Heated Enclosure Packages the industry standard for decades. Some of our most common units are shown below, and more can be found on the product page.
For 2” NPT high pressure control valves used in any application. Fits valves from any manufacturer including Kimray, Fisher, Belgas, BMD, Norriseal, and others.
5000 or 10,000 BTU/hr.
For 1” NPT high pressure control valves used in any application. Fits valves from any manufacturer including Kimray, Fisher, Belgas, BMD, Norriseal, and others.
2667 or 5334 BTU/hr.
For 1″ to 4″ flanged high pressure control valves used in any application. Fits valves from any manufacturer including Kimray, Fisher, Belgas, BMD, Norriseal, and others.
6000 or 12,000 BTU/hr.
Instrument Gas Heaters
Cold instrument gas or instrument air can cause issues for control valves. A Catco Instrument Gas Heater makes sure freezing pilots and instrumentation aren’t the problem. Stainless steel heat exchange tubing passes through an insulated enclosure, and a catalytic heater raises the temperature of the gas or air flowing through it.
2600 Series Single Coil Pilot Preheaters
Single or Dual Heat Exchangers
Single heat exchangers heat one stream of gas; ideal for a single piece of equipment. The dual heat exchanger is a popular choice when there are multiple instrument supply lines feeding your valves.
2600 Series Dual Coil Pilot Preheaters
High-Pressure Fuel Manifolds
Catco Instrument Gas Heaters offer several options for high-pressure manifolds and include both a regulator and relief valve. Stainless-steel and brass options are available from several top manufacturers.
5000 Series Single Coil Pilot Preheaters
Temperature Control
Only Catco offers the Steady Heat Controller. A hot and cold stream of gas are combined to provide a steady supply of heated gas that stays at a constant 135-140° F regardless of your operating conditions. Traditional thermostats are also available.
5000 Series Double Coil Pilot Preheaters
2600 or 5000 Series
The Catco 2600 Series has been the industry standard for decades and continues to work brilliantly in most conditions. The 5000 Series delivers more BTUs to keep you operational in especially harsh conditions and demanding applications.
Pipeline Packs
If there is intermittent flow or your valve is in a difficult-to-access location, heating the gas upstream of your control valve can be the better solution. Catco Pipeline Packs mount onto the pipe upstream of your equipment. This delivers heated gas while avoiding direct heat to a no-flow valve. Pipeline Packs are easy to install to an existing length of pipe, so installation is fast and simple.
For light-duty applications. Uses one or two 6×12 catalytic heaters. Installation requires a 15″ length of pipe upstream of the regulator. 3000 or 6000 BTU/hr. Available in a variety of starting voltages. See data sheet for full specifications.
For medium-duty applications. Uses one or two 6×24 catalytic heaters. Installation requires a 27″ length of pipe upstream of the regulator. 6000 or 12,000 BTU/hr. Available in a variety of starting voltages. See data sheet for full specifications.
For heavy-duty applications. Uses four 6×24 catalytic heaters. Installation requires a 27″ length of pipe upstream of the regulator. 24,000 BTU/hr. Available in a variety of starting voltages. Multiple units can be applied in series for higher BTU requirements. See data sheet for full specifications.
Custom Solutions
Whether you need a modified version of one of our common enclosures, a completely custom box for a unique installation, or a custom solution built from the ground up, Catco is here to help. Every year we deploy hundreds of custom solutions to optimize the performance of control valves in upstream, midstream, pipeline, and utility applications.
To begin the process for a custom solution, contact us with information about your application, or give us a call at 888-436-2095.
