Pool-Spa Installation
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.
