As an SF6 cylinder is emptied, liquid SF6 vaporizes and cools down the bottle. This reaction in cools the bottle to a point where the liquid SF6 loses the ability to convert to a gas. In order to counteract this, our Gas Cylinder Heater warms the bottle to an ideal temperature.
Our gas cylinder heater is outfitted with a thermostatically controlled thermostat. Once the heater is placed on the cylinder and plugged in, the thermostat will observe the temperature of the bottle which in turn determines the rate of warm-up. Once the temperature of the bottle reaches 120°F, the heater shuts off. If they bottle then drops below 90°F, the heater will turn back on.

Cylinders should be heated under static pressure, meaning no gas is flowing, and the liquid heated to 100-120F. To do this, use a filling regulator as a “thermometer.” Install the regulator onto the cylinder and leave it closed (no gas can flow) . Open the cylinder to see the SF6 pressure on the high side or input gauge. *Don’t forget the obvious step- put the heater on the bottle and plug it in! Monitor the pressure gauge and wait until it is within the range of 500-600 PSIG, which equates to 100-120F liquid temperature. Once you reach this- let ‘er rip, tater chip! A properly heated cylinder can be used until only vapor pressure is left inside the bottle. Questions, need additional support or a regulator, please contact us!
