]]> Ther are three options for temperature control on an Instrument Gas Heater.

Catco recommends our Steady Heat Controller, which mixes a hot and cold stream of gas to provide a constant outlet temperature around 135° F. This is warm enough to prevent freezing, but below the temperature that would damage most equipment.

Another method is using a thermostat. A probe is placed on the tubing to sense the temperature of the gas. Once it gets higher than the set point, a valve reduces the fuel input to the heater by about half. Then once the gas temperature drops, the heater returns to full power.

The final option is the turndown valve. It operates the same way as the thermostat, but manually. When the valve is in the closed position, it cuts the fuel input to the heater by about half. Open the valve to give the heater full fuel.

Low ambient temperatures increase the risk of freezing, but the driving factor is usually a combination of a high pressure cut and water content in the gas. […]

]]> There’s a phenomenon called the Joule-Thomson (or JT) effect that causes the temperature of a gas to drop when its pressure is reduced in a valve or regulator. Low ambient temperatures increase the risk of freezing, but the driving factor is usually a combination of a high pressure cut and water content in the gas. Every 100 psi of pressure drop causes natural gas to lose 6-8° F, so even in very warm weather frozen equipment can still be a problem. The JT effect is happening inside the valve, so in a lot of cases insulation jackets can make the problem worse.
