The principal use of the REGAL Gas Ammoniator is to provide a chloramination disinfection process.

The REGAL Model 310 Ammoniator is a vacuum-operated solution feed system designed for mounting directly to the valve of a REGAL MAN-1A wall mounted ammonia manifold assembly. The MAN-1A manifold includes a 30″ long flexible connector (MS-30) and a yoke assembly (Y-150A) for connection to the outlet valve of the ammonia cylinder (see typical installation drawings).

A highly efficient water operated, vacuum-producing ejector is close coupled with the ammonia solution diffuser. The ejector contains a back flow check valve. Ammonia gas flow rate is manually set using the rate adjustment valve and regulated by a spring opposed diaphragm regulator which is also the safety shut-off valve.

Dual scale metering tubes are provided with the following maximum capacities.
