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

The REGAL Model 316 Automatic Switchover Gas Ammoniator is a totally vacuum-operated system which is designed to automatically switch the ammonia feed from an empty cylinder to a full cylinder providing uninterrupted supply. Therefore, it is designed to provide system back-up.

The ammoniator regulators are designed for mounting directly to the valve of a REGAL MAN-1A wall mounted ammonia manifold assembly which then connect to the ammonia cylinder valves using a 30″ long flexible connector/yoke assembly (see typical installation drawings). Switchover from one cylinder to the other is self-actuation, eliminating the need for a separate switchover mechanism. A separate gas flow meter and rate control valve panel may be located wherever it is most convenient for the operator and connected between the vacuum regulator junction at the pressure relief valve, and the ejector, by means of safe vacuum tubing.

The ejector assembly contains a back flow check valve. Ammonia gas flow rate is regulated by a spring-opposed diaphragm regulator which is also the automatic safety shut-off valve. A pressure relief valve provides a central interconnection point for the vacuum tubing.

Dual scale metering tubes are provided with the following maximum capacities.
Minimum feed rate is 1/20th of maximum
