Water Sample Cooler

If there is a requirement to sample hot or boiling waters, the installation of sample coolers is essential for the following reasons.

Safety:

To ensure compliance with health and safety regulations. The health and safety act 1974 requires employers to provide a safe method of sampling water in boiler plants.

Accuracy:

A significant portion of any heated water sample will be lost to atmosphere as steam flashes off which means that the resultant sample will not be representative.

Convenience:

Opening of drain plugs or loosening of pipe can be extremely difficult regardless of the safety hazard.

Application:

Sample coolers should be installed whenever it is necessary to obtain a sample of water from a system where the operating temperature exceeds 60 degrees. C. i.e. steam boilers, steam and condensate mains.
Closed heating circuits, and water systems.

Installation:

The sample cooler should be installed as close as possible to the system take of point at a height to facilitate convenient operation; the unit must be mounted vertical.

An isolating valve capable of withstanding the full system pressure should be installed immediately to the take of point.

The cooling water should be taken to a suitable drain through a tundish.
