Freeze Protection - Fire Sprinkler Lines

 

 heatsafe-for-tm-2-.png

RC38 Fire Protection Association recommends the following:

 

Many premises have areas which could be subject to freezing temperatures, for example:

(a)unheated or inadequately heated buildings;
(b)parts of heated buildings exposed to frost, such as ceiling voids or near open doors such as loading bays;
(c)chillers and cold rooms; (d) external pipelines from a remote mains water supply or pump house to a sprinklered building;

(d) the pump house (BS EN 12845, Clause 10.9.2, requires that diesel engines be maintained above  5°C for ease for ease of starting);

(e) areas normally heated but temporarily unheated during out-of-work hours, weekends or winter holidays;

 

1.3 Main frost protection methods

The methods available for protecting areas and water-filled equipment from freezing are:

(a)maintaining adequate heating throughout the building (preferred option, where possible); or
(b) providing localised heating and/or trace heating and lagging to pipes, valves, tanks and ancillary equipment; or

(c) using a dry sprinkler pipe or alternate wet/dry sprinkler pipe installation; or (d) using dry drop    sprinklers.

 

BS EN 12845, Clause 11.1.2.2

Duplication of heating elements BS EN 12845, Clause 11.1.2.2, requires that there shall be duplicate heating elements to protect pipework. Each of the elements should be capable of maintaining the pipework at the minimum temperature and each trace-heating circuit should be separately switched and monitored.
