Hypogen System

Liquid Chlorine New Zealand’s range of onsite sodium hypochlorite generators, Hypogen® can produce up to 48kg per day of chlorine and are designed as an alternative to chlorine gas or commercial sodium hypochlorite.

The Hypogen® system is made up of the following components:

Control System:
The Hypogen series of onsite sodium hypochlorite generators are fully automatic and are controlled using a PLC and colour operator touch screen. The colour touch screen makes the system extremely easy to understand and operate, while giving the operators detailed graphical information on the system. There are numerous alarm conditions that lockout the system, including low mains water inlet flow, low brine, high water pressure and high and low electrolyte temperature alarms. The system is also able to automatically re-start for a set number of re-tries due to low water flow and water temperature alarms, before shutting down.  

Operator Interface Overview Touch Screen

4G Modem:

The Hypogen system comes with a 4G modem to enable the system to be remotely monitored and controlled. This allows the system to send out email alarms, push notifications, which once received by the operator or Liquid Chlorine New Zealand the system can them be remotely interrogated and alarms reset, giving operators freedom, while having the knowledge of the generators current status at all times

Electrolyser Cell: 
The key component in any electro-chlorination system is the electrolyser cell. We offer both standard non-membrane electrolyser and membrane eletrolyser. 

The Hypogen S system produces onsite low strength up to 1.0% sodium hypochlorite through the electrolysis of the brine solution in a non-membrane cell, which takes place in a once-through process. The brine solution enters the electrolyser cell, and as it travels through the cell electricity converts the brine solution into low strength sodium hypochlorite.

The Hypogen M and pH systems use membrane cells. In a membrane cell, the cell is divided in two via the membrane, on one side of the cell sodium hydroxide and hydrogen gas are produced and on the other side of the cell sodium hypochlorite. Depending on the configuration of the systems depends on how the two products are combined after the membrane reaction.

Positive Hydrogen Removal & Dilution:
A by-product of any electrolytic chlorine generation process is the production of hydrogen. To eliminate any concerns with the accumulation of the hydrogen to create a potentially hazardous concentrations, all Hypogen systems utilise an air blower to dilute any hydrogen to well below its flammability limit. Combined with sealed bulk storage tanks, the diluted hydrogen is force ventilated to a safe outdoor discharge point. Air flow monitoring is used to check the blower is operating, along with a current sensor to ensure there is no risk to safety and the system can operate.

A water softener is installed where the brine solution hardness is greater than 17mg/l. This is to ensure the maintenance free operation of the Hypogen system and protect the electrolyser cell scale buildup.

Salt Saturator: 
Liquid Chlorine New Zealand install large saturators which allows the salt to be stored indefinitely, while having enough capacity to provide continual production and requiring minimal refill cycles from the operators. The make-up water operates automatically and is sensed via a level sensor. The water passes through the salt bed forming a saturated brine solution of approximately 32% strength.

Storage Tank: 
The bulk chlorine storage tank allows chlorine to be stored for future use and to provide the release and removal of the hydrogen produced from the generation process. A level sensor is installed in the storage tank that start and stop the Hypogen system. The storage tanks are generally size to provide 3-4 days storage, although this can be increased or decreased to suit available space and site requirements.

Installation & Service:
The Hypogen series of onsite sodium hypochlorite generator are easily installed into your existing system or new plant. The main components are pre-assembled with only the main connections and interface piping between the supplied components required. Liquid Chlorine can organise the complete installation and system changeover service if desired.

The Hypogen system needs to be serviced on a six-monthly basis. This is to confirm the system is operating correctly and clean the electrolyser cell if required. All that is required from the operator onsite is the regular addition of salt into the salt saturation tank.
