Why do gas regulators ice over? ❄️

When high-pressure gas drops to a lower pressure, the temperature drops too. This is called the Joule-Thomson Effect, and it can cause regulators, valve bodies, and other pressure points to frost or ice over.

Once equipment freezes, gas flow can be restricted or stop completely which is why directed heat matters.

One small component can make a big difference in heater safety.
Our shutoff valve is designed to work with the thermocouple to stop gas flow when the heater is not properly heating. After the problem is resolved and the correct temperature is restored, the valve can be manually reopened.
It’s one more way CATCO helps support safe and dependable operation in the field.

Need better control over your heater temperature?

Our CATCO thermostat allows you to set your desired temperature and automatically regulates fuel flow to maintain it.

Install the probe in the gas stream to get an accurate reading, and the system will adjust as needed.

Reliable heat starts with controlled heat.

If you're looking for precise temperature regulation, CATCO’s Steady Heat Controller is your best friend.

It regulates heated gas and ambient gas to maintain a controlled temperature throughout your system — preventing excess heat from damaging sensitive equipment.

Because reliable heat is good.
Controlled heat is better.

One job. One shell.
The CATCO Weather Cover protects your instrument gas heater from dust, water, debris, and whatever the environment throws at it—keeping performance high and downtime low.
Everything inside stays protected. Exactly how it should be.

Correct placement = correct data = reliable operation.

Happy New Years from our Catco Family to yours.

Stay warm and Thank you for being apart of our energy journey.

Winterization for gas systems isn’t just about buying new equipment — it’s about maintaining what you already have and preparing before the freeze hits.

We break down what winterization really means and the three categories every system falls into.

We got you an early Christmas gift — here it is.

These slides walk through a simple winterization checklist designed to help teams stay proactive, catch small issues early, and keep equipment running when cold weather hits.

The full checklist is meant to be shared internally so everyone knows what to look for this winter.

If questions come up along the way, we’ve got you covered — our team is happy to help you get winterized this season.

Wishing you a safe, warm, and reliable holiday season. 🎁❄️
