Gas Chlorine

Most pools in the country have veered away from gas chlorine as method of chemical treatment in pool, due to health hazards and fire marshal rating. The local market which uses gas chlorine is Arizona. The local supplier is AES (Aquatic Environmental Systems).

Designing a gas chlorine system, many safety features are required; they include as a minimum of design: audible & visual gas leak alarm, air scrubbers to clean the air, high flow air exchangers for room (refer to local fire marshal), eyewash and shower station, fire rated rooms and doors, fire sprinklers (if required).

Gas chlorine, a yellow-green gas which is two and a half times heavier than air, is the most effective sanitizer on the market, providing 100% effective chlorine delivery.

Chlorine gas is extremely corrosive and has been known to corrode all metal within an equipment room.  All metal within the room should be specified as top-grade stainless steel, but expect the life span to be very short.

Chlorine gas is shipped and stored in pressure tanks, generally 150 pounds.  Smaller tanks are available, but not practical.  The tanks rest on a scale, which indicated when the tank is near empty.

Because the gas is heavier than air, locate the fans/vents near the floor for adequate ventilation.

Gas chlorine use for swimming pools is prohibited by the NYC Health Department.
