Gas Feed Equipment
Chlorine Gas – The Safer Choice
- Chlorine gas is not flammable or explosive.
- According to data from the Association of Poison Control Center, gas chlorine has far less chlorination exposures than any other forms of chlorine.
- Cylinder mounted systems draw chlorine from the container with a vacuum, so that a leak of any system component results in the automatic and immediate shut-off of the chlorine.
Key Points:
- Consistency and repeatability of feed rate make it operationally the most reliable.
- Modern gas feeding equipment occupies very little space.
- Doesn’t produce byproducts such as chlorite or chlorate ions
Benefits of Gas Chlorine
- Environmentally friendly – Gas chlorine comes in reusable cylinders so there are no disposal issues.
- Does not degrade – Stays at full strength and does not matter how long it’s stored.
- Saves money – 100% elemental Cl2. Gas chlorine costs less than other forms because bleach or granules are not 100% chlorine.
Gas chlorine is 100% chlorine per pound vs. calcium hypochlorite with is approximately 65% chlorine per pound or sodium hypochlorite (bleach) which contains approximately 12% chlorine per gallon. You need less gas chlorine to do the same job as calcium hypochlorite or sodium hypochlorite (bleach).
Bottom Line: Gas chlorine is the most cost effective option.
