Asin Aqua Profi Professional Chlorine & PH Automatic Pool Dosing & Pool Management System


1. Description

The ASIN AQUA Profi is the top of the range professional swimming pool automatic dosing system for commercial or large domestic pools.

It provides fully automatic control of pool dosing as well as control of the pool circulation pump and pool heating.

It is internet enabled allowing remote monitoring of the pool chlorine, PH and temperature via a smart phone or the internet.

The ASIN AQUA doesn’t come with any dosing pumps and can be connected to any number of external dosing pumps to provide an unlimited capacity for even the largest pools.

The ASIN AQUA Profi has an easy to use colour touch-screen control panel

It comes with a flow meter to detect when the pool circulation pump is running so that dosing only occurs when the pool water is flowing.

The ASIN AQUA Profi can be used for large private or  commercial pools up to an unlimited pool size.

It has simple and clear operation, whilst measuring and regulating the Chlorine and PH levels in your pool.

This is an automatic dosing system which can be used for both indoor or outdoor pools

The system automatically monitors the level of chlorine and PH in the pool and adds the required amounts of chemicals to maintain the pool at the desired levels.

It has an easy to use touch screen control panel, which allows you to set the desired level and monitor the current levels of chlorine and PH in the pool.

The ASIN AQUA Profi measures:-

  1. pH
  2. Free and total chlorine
  3. Redox potential
  4. Pool water temperature (with optional water temperature sensor)
  5. Pool Water level (with optional water level sensor)


As well as controlling the level of liquid chlorine, the The ASIN AQUA Profi can also control one or more salt chlorine generator cells

It can control PH+ and PH- as well as flocculent

Chlorine control and dosing

The ASIN AQUA provides highly effective disinfection treatment of pool water for public and private pools. Precise measuring of chlorine content in the pool water by the free chlorine probe combined with the system digital intelligence.

pH control and dosing

ASIN AQUA Profi is adjustable to dose pH MINUS or pH PLUS. Treatment for stabilizing of pool water acidity at the optimum level. Precise measuring by pH probe combined with the system digital intelligence controls the preset pH level of the circulating pool water in all pool operation modes and variable environment conditions.

Algaecide daily dosing

The ASIN AQUA can dose a small amount of algaecide to both outdoor and indoor pools using a dosing pump. The regular addition of algaecide prevents the growth of all types of algae, mould and bacteria.


Adding a small amount of flocculant to the pool water improves the efficiency of the filtration process.

The effect of this is to greatly improve water clarity.

Slow continuous dosing of flocculation and coagulation aids that improves the capability of filtering so even the smallest invisible water impurities that are in standard conditions become unable to pass through the filter.

5. Optional Dosing Pumps

The Asin Aqua Profi can be connected to most types of pool dosing pumps.

We can supply a range of dosing pumps which are compatible with the Asin Aqua Profi:-

5.1 PP60 Dosing Pumps


These are available in 12v or 240v models

High-performance and high-quality peristaltic pump with output of 60 – 120 ml/min.

Ideal for dosing of pool chemicals. Up to 1 bar of pressure.

Unique design and construction of the pump ensures long-lasting durability and stable performance. For dosing of disinfection, flocc and pH fluids

The PP60 pumps are suitable for pools up to 200 m3

5.2 DDE Membrane Dosing Pumps

The DDE dosing pumps have an output of 5 l/hr.

Two models are available – for PH and Chlorine

Membrane pump DDE-CL 5l/h – for liquid chlorineMembrane pump DDE-pH 5l/h – for pH control

Membrane dosing pump for pools up to 800 m3 or in the systems where pressure exceeds 1 bar.

Teflon membrane and viton body with ceramic valve allows it to work with aggressive pool chemicals.

5.3 Membrane pump DDA 30l/h

The DDA membrane dosing pumps have a higher output of 30 l/hr


Membrane dosing pump for pools over 800 m3 or in the systems where pressure exceeds 1 bar.

Teflon membrane and viton body with ceramic valve allows it to work with aggressive pool chemicals.

6. Optional Remote Display

An optional remote display panel can be connected to the ASIN AQUA via a cable

The display has an attractive glass design and is normally located in the pool hall

The remote display shows:-

  1. Pool Water temperature
  2. PH level
  3. Redox or free chlorine level (depending on model of ASIN AQUA purchased)


7. Optional Items

Various optional items are available with the ASIN AQUA range of pool dosing systems


  • Remote display – see section above
  • Pressure type sensor – measures the water level in the pool and can allow the ASIN AQUA to operate an automatic water top up valve
  • ZPM coagulation mixer – mixes the flocculant into the water
  • Inserting DN50 plug 1/4″ threaded – cap to go into a 50mm t-piece. Allows the dosing injection valves to be screwed into the cap. Provides a neater solution than drilling and tapping into a pool pipe elbow
  • PH7.00 and redox buffer solution – used to calibrate the probes. The probes are inserted into some of the solution to provide a reference level to check the calibration of the probes
  • Air thermometer – allows the ASIN AQUA to act as a frost stat to turn the pool circulation pump on when the outside air temperature falls towards zero. It also allows the ASIN aqua to control the pool heating based on the outside air temperature
  • Total chlorine probe (CLT) displays the amount of total chlorine in the pool

We also sell a drill and tap set to allow you to drill and tap the correct thread into a pool pipe fitting (eg elbow)


Prices shown for optional extra items are for when they are ordered together with the ASIN AQUA dosing system. Additional delivery charges will apply if the optional items are ordered on their own.

8. Pool Heating Control

The ASIN AQUA Profi includes the ability to measure the pool water temperature and then control the heating to turn the pool heating on and off as required to maintain the desired temperature.

A volt-free relay in the ASIN AQUA can be connected to virtually any type of pool heat pump or pool heater. (please contact us for further advice on how to connect this to your particular pool heat pump or pool heater).

This is inserted into the pool pipework so that the pool water temperature can be measured.

Pool Water Temperature Sensor and Pocket Connection of temperature sensor to pool water

Please contact us for more information on these options

9. Remote Monitoring via Smartphone and Internet

The ASIN AQUA Profi comes with an RJ45 Ethernet socket. This allows for connection to your internet router.

This allows remote monitoring of your pool chlorine, PH and temperature levels via either an app on a smartphone or via an internet web browser

The IPool Live App is available free of charge to all ASIN AQUA Home users.

Watersens Chlorine & PH Automated Dosing Systemipool-live-app-pic2.JPG

The app allows the user to remotely monitor the levels of chlorine and PH for the pool

Alerts can also be set so that if the chlorine or PH fall below or above a set level, an alert is sent to warn the operator.

This data can be viewed for a 30 day period using the iPool app or web browser.


If you do not have an internet connection where the ASIN AQUA will be located, an easy solution is to use a pair of powerline adaptors. One of the plugs goes into a socket in the pool plant room. The other plug goes next to the wifi router in the house.

An Ethernet cable is then connected from the powerline adaptor to the router and the ASIN AQUA to deliver internet connectivity.

Please contact us if you would like advice on the best way to get internet connectivity to the pool plant room.

11. Chemical Bund Tanks

We recommend that you purchase two (or more) chemical “bund” tanks

These allow the standard 20 and 25 litre containers of liquid chlorine and acid to simply be placed inside the bund tank

This makes it very easy to swap the containers when they are empty

The bund tank is designed to hold all of the 20 or 25 litres of pool chemical should the container leak or split.

The bund tank then prevents the chemical from spreading over the floor of the pool plant room which could cause damage to the equipment in the plant room.

We have two types of bund tank available:-

  1. Rectangular bund tank (without the raised back)
  2. Carboy bund tanks (with a raised back)

Rectangular Bund Tanks


The rectangular bund tanks measure 210mm high x 300mm wide x 500mm deep

Carboy Bund Tanks

The carboy bund tanks have a raised back
