• Foundries

Providing the ventilation requirements for heavy industrial environments requires an understanding and knowledge of the specific application.

There are a number of application solutions in place for ventilating many individual processes; the challenge involves incorporating the diverse systems found within these facilities into easily understood and maintainable ventilation solutions.

The ventilation requirements must be flexible enough to meet process and occupant needs during both summer and winter months, whilst protecting workers from the severe environments encountered in these facilitates.

Particularly challenging environments include the foundry industry, operating in severe conditions with demanding process requirements. By providing inadequate ventilation, this can lead to the premature wear of equipment, excessive maintenance costs and compromised product quality, as well as exposure of the workforce to airborne contaminants.

Foundry work occurs in a very hot, noisy and potentially hazardous environment. In particular, the furnaces and molten metal in a foundry create a hot working environment.

Dehydration, heat cramps, heat exhaustion and heat stroke are some of the health effects foundry workers can experience from exposure to this excessive heat. By removing unnecessary sources of radiant heat and changing the working environment will help reduce heat in work areas using local ventilation, spot coolers, blowers and fans to reduce the air temperature.

Hazardous substances are widely used in foundries. Exposure can have a damaging effect on the health of foundry workers if they are not properly protected. Ways to help protect workers from exposure to hazardous substances include using local exhaust ventilation to remove contaminated air directly from the source.

The foundry industry encounters some additional material-handling issues:
Foundries include facilities for the pouring of molten metal - primarily steel, cast iron or aluminum into a sand mould. Metal castings are common in most manufacturing processes and are used for making parts of all sizes, shapes and materials.

Commonly, foundries have problems with the ventilation of work zones. Usually, there is an imbalance between fresh air and exhaust air. The problem is often compounded by a dusty atmosphere and sometimes high carbon monoxide (CO) content.

Excessive air exhaust results in high under pressure in the building and draught problems. In production areas inside foundries, the existence of too many exhaust points and the lack of a system for air supply may have created this negative pressure. At the same time that the production creates a heat surplus (wasted by the exhausts) additional heat must be supplied by other means to the fresh make-up air being brought in from the outside in the winter.

Elta Fans provide a wide range of ventilation products for foundry applications, specifically designed around the type of foundry, and the arduous environmental conditions to which workers are exposed, 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.
