Pool-Spa Installation

With easier installation and maintenance, the bypass line assembly provides better protection and security as well as ensures a smooth flow of water around the sensors

SIMPLE Installation 

We want to make the installation of CHEMTROL® controllers as simple as possible. This is why we have everything mounted onto a customised assembly manifold ready for connection.

This assures proper water sampling around the sensors and makes for a hassle free installation that minimises the integration work needed to get your water treatment system up and running.

Listed below are a number of different installation options for use by architects and engineers in the preparation of requests for bids.
