The design & manufacture of Steam Heated Vaporizer meets Chlorine Institute recommendations for liquid vapourization by low pressure steam. The liquid is inside the tube and the heating media is steam vapour which is outside the tube. 
The vapourizer design pressure of 300 lbs meets Chlorine Institute Recommendations with corrosion allowance of 3 mm on chlorine side and 1.5 mm on steam side. 

Series SC 70 Vapourizer is of heavy duty construction. The internal and external surface of the vapourizing chamber can be easily inspected during servicing which is an unique feature of the design. Ease of cleaning is an added advantage to remove the sediments. 
SC 70 can be easily cleaned by removing the top bolt. Suction trap has a sacrificial chamber provided at the gas outlet which protects the main body from corrosion attack.

The Steam chamber has nozzle connections for steam inlet, condensate outlet, pressure gauge, pressure switch and pressure relief valve. Insulation on shell must be done by the client at site.

OPERATING PRINCIPLE 
In operation, liquid is introduced through liquid inlet which is connected to the bottom of the vapourizer tube by a dip pipe. Here the liquid rises to contact sufficient surface to meet the vapour demand rate. After equilibrium is reached vapourizer operates at essentially on container pressure.

As gas demand reduces, vapourizer the pressure at the vapourizer raises thus reducing the inflow of liquid feed. On sudden shut down of gas valve, liquid would be forced out of vapourizing chamber back to the container.

With evaporation, the vapour raises through the vapour baffle to the super heating chamber, enters the suction trap and leaves through the gas outlet. Suction trap collects moisture and prevents such moisture from corroding vapourizer chamber. Since suction trap is not a pressure part it can be severely corroded without impairing operation or safety.
