Behind the panels: 6 Cooling system manifolds

This "Behind the panels" blog shows 6 Cooling system manifolds on two panels.

A solution for a centralized measurement and control of the water quality from 6 cooling systems. A bypass from the circulation line is brought to the panel.

1 Panel has 2 sample manifolds and a XS controller. The other panel has 4 sample manifolds and a MT controller.

Each sample manifold includes the conductivity sensor, a sample valve and a flow switch.

Sample manifold

Functions of the controller in this application:

• Measure the conductivity and control a motorized blowdown valve

• A biocide timer program activates a dosing pump to inject biocide in the system

• Pulse water meters on the incoming and blowdown water line are connected to the controller to log the water consumption and calculate the evaporation.

• An inhibitor program activates a dosing pump to inject inhibitor in the system, based on the incoming water flow rate

• Both the inhibitor and biocide programs have a bleed lockout or pré-bleed function in order to prevent to bleed away freshly added chemicals right after injection

• The flow switch interlocks dosing or bleeding actions when the system is not running

• All measurements and relay actions are logged and visible on the controller, online or through download
