TWSCO Specialty Gas Cylinder Jackets are designed to heat and insulate cylinders in order to prevent gases from condensing inside the cylinder.
Cylinder jackets are commonly used with hydrocarbon and protocol mixtures to protect against inaccurate calibration and process control when cylinders are exposed to low temperatures.
These cylinder jackets are constructed with a self-limiting heating element that prevents over-heating. As temperature increases, element resistance rises resulting in lower amperage to the heater. Lower amperage causes a wattage drop, thus limiting maximum attainable temperatures.
Our jackets may be used to maintain cylinders at 60°F during outdoor winter conditions or to heat cylinders up to 120°F in ambient temperatures. They are constructed of materials approved by Underwriters Laboratories Inc. for Class I, Division 2, Group B, C and D.
Blankets with Class I, Division 1, Group B, C and D ratings are also available.
