Sustainability: Swimming Pools and Spas
Sustainability and Cost Benefits of CHEMTROL Controllers: Swimming Pools and Spas
With temperatures and energy bills on the rise we all need to come up with smart solutions to mitigate these impacts on the environment, not to mention increasingly stretched budgets.
A major part of devising a sustainable solution should start with identifying what your energy costs are, especially for large public facilities. From here you can look at where savings can be made, set targets and initiate a management plan that improves your facilities overall efficiency and reduces costs.
With this in mind we want to highlight how our range of smart automated water treatment systems can improve efficiency and help you meet a greener (and less costly) standard of operation.
CHEMTROL PC5100 programmable controller reduces UV energy consumption
In this example we have identified where our CHEMTROL PC5100 programmable controller can help reduce UV energy consumption, and carbon emissions, using three public swimming pools/spa to illustrate this feature. Ultraviolet systems are popular for their ability to harnesses the power of ultraviolet light to disinfect and sanitize pool water, but they do draw power when they operate.
Our analysis of three public swimming pools & spa over the month of February 19, one indoor (top graph), one outdoor (Middle graph) and the other is a spa (bottom graph), show clearly that the UV systems are operating unnecessarily, and drawing power when they could be in standby mode/off.
The reality is that UV systems only need to operate when Combined Chlorine levels are more than 0.8ppm (above the red line).
In our examples below the outdoor pool and the spa’s UV systems should only be activated a few days per month, while the indoor pool’s UV system should only be operating every day for a few hours. In both cases, there are opportunities to realise significant energy savings given these systems should be turned OFF when measurements are between 0 ppm – 0.8ppm, so there is no need for these systems to work 24/7.
Operators must bear in mind that these three case studies are only used to illustrate the potential of our product. Every facility and pool has its own set of unique circumstances and conditions.

CHEMTROL PC5100 programmable controller
The CHEMTROL PC5100 has a range of unique features, including the ability to measure both Free and Total Chlorine – a unique technology to control dual ppm and measure combined chlorine. It is also incorporates all the monitoring, control and communication functions into a single integrated command center designed around a powerful microprocessor, with an industry-leading 5 year electronics warranty.
The CHEMTROL PC5100 programmable controller can be connected to your facilities UV system via a dedicated relay to automatically control it based on combined chlorine measurement. The menu on this unit also has a UV cooldown period to protect the UV system in case it needs to be repeatedly turned on and off.
In addition the PC 5100 can connect to UV systems that include 4-20mA electronics, and facilitate automatic control of the UV Sterilization System using a 4-20mA output to ramp up and down the system based on the prevailing chloramine measurement.
