1 INTRODUCTION
1.1 General Description
CAPITAL CONTROLS® Series 71V3B Electrically Heated Vaporizers are used to convert liquid Chlorine, Sulfur Dioxide
or Ammonia, as specied at time of purchase, into a superheated gaseous state. The Vaporizer consist of a vaporizing
chamber housed within a self-standing vented water chamber heated by an integrally mounted electric immersion
heater. The Vaporizers are equipped with controls and gauges to provide safe operation under normal conditions and
close supervision.
Functionally, liquid chemical from the supply system is directed into the bottom of the vaporizing chamber, absorbs
heat from the hot wall of the chamber, is converted from liquid into gas, and is discharged through the gas outlet
opening at the top of the chamber to the gas handling components of the system requiring the gas.
The maximum capacity of these Vaporizers, all similar in design and construction, is related to the liquid chemical
being handled and the rating of the electric immersion heater. These capacities are listed in Table 1-1.
WARNING: All components of the Vaporizer System are constructed of materials capable of with standing the
corrosive action of the particular gas for which the system has been specied. Never use any component for
handling a gas dierent from which it has been purchased.
