Waterco's Chemflo fresh water chlorination and pH controller

The Chemflo range includes: ORP & pH controllers, ORP controllers & feeders, pH controllers & feeders.

Chemflo Chlorination and pH Controller
Chemflo automatic control systems measure and precisely control set levels of sanitiser (chlorine) and pH balance (acid) through feedback from inline sensors. This ensures the safest possible swimming conditions. Costs are reduced by minimising chemical use and preventing excessive addition of chemicals that may damage the pool and its equipment.

Power requirements are minimal, Chemflo's control systems only operate occasionally to adjust ORP and pH levels to an optimal set point. Chemflo pumps can easily cope with sudden demands, dosing liquid chlorine quickly during high pool usage.

Chemflo pH / ORP Controller - Automatically monitors and controls pH and ORP levels.

• Combination pH and ORP sensor.
• Injection and sensor tee.
• Automated pool pump timer output.
• Super chlorination function (not included in Chemflo pH controller).
• Pool filter backwash function.
• Pump to waste function.
• Dosing pump shut off feature.
• Alarm function.

Sensor and Injection Tee
The Chemflo controller's sensor has a threaded cap for easy in-line mounting into the injection tee which has injection points for pump output tubes. The injection points have built-in non-return values. The sensor has a leak proof seal and can be easily removed for cleaning.

Automated Pool Pump Timer Output
A pump timer controls the main pool pump, chemicals are only added when the pump is running. There is the option of Summer, Winter, Auto and Custom modes.

• Summer mode: pump operates 4 hours in the morning, 4 hours in the afternoon.
• Winter mode: pump operates 4 hours in the afternoon only.
• Auto mode: automatically changes to Winter mode on 15th May and returns to Summer mode on 15th August. (15th November & 15th February respectively for the Northern Hemisphere).
• Custom mode: allows user to enter 1 or 2 pump cycles per day at times of their choice.

The Automated Pool Pump Timer eliminates the need for a separate pool timer. A battery back-up is incorporated so there is no need to re program it, if there is a power failure.

Super-Chlorinate Function (Excludes Chemflo pH Controller)
No need to handle liquid chemicals for super-chlorination. The Chemflo controller handles it for you, and returns to normal control operation afterwards.

You can enter the number of litres of Chlorine you wish to add. The pool pump is set to operate for 4 hours once super chlorination is complete, ensuring total mixing.

Pool Backwashing Function
The Chemflo controller prompts the user to set the filter control to Backwash, Rinse and Normal Filtration as required. The pool pump is switched off whenever the filter control is being changed. Chemical addition is disabled while backwashing.

Pump to Waste Function
The Chemflo controller prompts the user to set the filter control to "Pump to Waste" and Normal Filtration as required. The pool pump is switched off whenever the filter control is being changed. Chemical addition is disabled while pumping to waste.

Dosing Pump Shut Off feature
If the Chlorine and/or Acid pumps pump chemicals continuously for more than the selected time, the pump(s) will shut off. This prevents excessive chemicals being added to a pool in the event of an instrument or probe fault.

Alarm Function
If the ORP and/or pH readings go beyond the Set Point(s) by a preset amount for a preset time, the display will show an alarm message. The Chemflo controller continues automatic control to attempt to bring the reading back within the Set Point.

The alarm safeguards against overdosing or under dosing in the event of an instrument or probe fault.
