Monitoring the Air in Indoor Swimming Pools


Source: PPM Technology

PPM Technology are co-operating with our long-standing partners Tennants Distribution Ltd in an exciting new project for monitoring the indoor environment in indoor swimming pools. We have recently supplied 2 monitoring units for use in a swimming pool environment, a large IAQ monitoring unit containing sensors for Temperature, Humidity, Chlorine, Ammonia, Carbon Dioxide and Carbon Monoxide, and a Mini IAQ Monitor with sensors for Temperature, Humidity, Carbon Dioxide and Carbon Monoxide.

Chlorine products are used in swimming pool to prevent growth and spread of bacteria and viruses. Nitrogen pollution produced from organic derivatives. (sweat, urine) The combination of the Cl2 & N2 containing compounds reacting together can produce Trichloramine (NCl3). NCl3 can produce the same effect as Tear gas and is found in dangerous levels in indoor pools. We are currently sourcing sensors for NCI3 that coul be used in this environment.

Continued exposure to high levels of chlorine, are though to cause long term health issues for swimmers and pool employees. Including respiratory problems such as asthma.

The Wireless IAQ Profile Monitor system is a integrated wireless system for monitoring multiple indoor air quality (IAQ) parameters, including but not limited to -

  • Temperature
  • Humidity
  • Carbon Dioxide
  • Carbon Monoxide
  • Formaldehyde
  • Nitrogen Dioxide
  • Sulphur Dioxide
  • Ozone
  • Ammonia
  • VOC’s
  • Glutaraldehyde.
  • Chlorine.
  • Methane.
  • Smoke.

There are currently two instrument models available, the full-size IAQ Monitor (containing up to 7 sensors) and the Mini IAQ Monitor (Up to 5 sensors). A large number of monitoring units can be networked together to enable complete monitoring of an entire building. Each monitoring can come with unique sensor options if necessary.

One unit is connected to the controller PC; the PPMonitor sofware allows the entire wireless system to be managed from a single PC, the PC can pre-set a number of different exposure levels to trigger when limits are exceeded; these could be visible or audible alarms or to control 3rd party systems such as ventilation systems. The software enables the data to be viewed graphically, produce reports and statistical data.
