GAS WARMERS

(OLD DEFINITION)

On occasion, the gas in cylinders is withdrawn so fast that the regulator could ice up because of the change in temperature.İf this occurs, an electrically heated gas warmer is available to be installed in-line, and this warmer would heat the gas out of the cylinder before it reached the regulator.The rule of thumb is to consider a warmer if the use of gas exceeds 35 acfm.The actual figure should be based on experience with the specific type of gas being used.Ask the supplier what his or her experience has been.Carbon dioxide is a particular problem.

(NEW DEFINITION)


Ruttan's Air Warmer is a double box-stove, which heats by radiation, and also by air which is brought from without, warmed by passing between the inner and outer plates, and delivered into the apartment. The inventor, however, was so intent upon a "system of ventilation" which implied the adaptation of the house to it, that he failed to make his stoves readily available for ordinary use.
