The principal use of the REGAL Gas Sulphonator is used to dechlorinate water, wastewater and industrial process water with gas sulfur dioxide. The simple, efficient design has made REGAL Gas Sulphonators the industry standard. Built with heavy duty corrosion resistant parts, REGAL Sulphonators provide safe, long-lasting service.

The REGAL Sulphonator incorporates the very best available materials with the latest technology in design and construction, to reduce maintenance, simplify construction and improve operation.

• System Back-up – Each cylinder’s sulphonator has its own vacuum regulating diaphragm and safety/inlet valve insuring that sulphonation can be continued if service should be required on either sulphonator.
• Corrosion-resistant and Factory-adjusted Detent Mechanism – Detent does not require any field adjustment assuring that cylinder switchover will occur at the proper time, and that all available gas in supply cylinder will be used.
• In-Use/Stand-by Indication – Prominent indicator on face quickly tells which is the stand-by cylinder and which cylinder is in use.
