• Plant Rooms

It is important that plant room areas are carefully ventilated as required, so as to ensure the correct operation of plant, as well as the safety, health and comfort of personnel.

Within a plant room environment, individual staff may be exposed to a variety of contaminants. There are a number of common airbourne contaminants, which include carbon monoxide from poorly-turned forklifts, welding smoke, dust, process vapours, and volatile organic compounds.

The levels or these types of contaminants may be typically low enough not to create a hazard to employees, although there are instances when levels can rise, which could lead to discomfort.

Many manufacturers ventilate plant rooms with mechanical ventilation, utilizing wall mounted or ceiling extract fans. However, as outdoor temperatures decrease, employees often shut doors and windows to keep the plant warm. As doors and windows are closed, extract fans can be starved for air if there is not a sufficient supply of makeup air.

Consequently, the performance of ventilation systems can then degrade and the building pressure may decrease to a point where down drafting of combustion vents occur, creating an additional health risk.

Dilution by ventilation is an effective means of decreasing exposure to indoor air contaminants. This approach is conceptually simple - provide sufficient make-up air to the plant room to dilute contaminants to safe levels.

There are a number of specific plant room applications where Elta Fans can assist, in particular:

Boiler rooms and other areas holding fuel-burning appliances should be provided with sufficient fresh air in order to meet the needs for combustion, as well as preventing overheating of the space. Furthermore, the compliance with those regulations which govern the ventilation of these appliances must be maintained. Where rooms exist containing gas installations, these should be ventilated to prevent the build up of gas which could occur as a direct result of minor gas leaks. Ducts containing gas pipe work should be ventilated to a safe position, preferably direct to outside air.

Refrigeration plant rooms should have adequate ventilation as required for the safety, health and comfort of personnel, as well as for emergency purposes in the event of a major leak.

Battery rooms, depending on type of batteries present, ventilation should be provided so that any potentially explosive gaseous mixtures are dispersed safely below non-hazardous levels. Battery life can also be reduced by high continuous space temperatures, for e.g. temperatures greater than 25°C.

Electrical plant rooms, it is important to ensure there is adequate ventilation for rooms which contain electrical plant, thereby preventing the build up of heat generated by equipment. Specific examples where ventilation would be required would include:

  • IT, communications rooms and incoming frame rooms that have active heat generating equipment
  • Transformer rooms
  • Uninterruptible power supply (UPS) rooms
  • Electrical switch rooms

Elta Fans provide a wide range of ventilation products for plant rooms, so for more information, please look at examples of typical products that could be used for these applications or alternatively, please contact us to discuss your specific application requirement.
