Port-A-Cool Explosion Proof Units Offer Cooling Alternative
03 June 2008
Offshore drilling rigs are exposed to some of the most severe environments imaginable. High levels of humidity and salt spray must be continually battled to ensure metal surfaces escape corrosion and permanent damage. No matter what the weather brings, rig operators are challenged every day to protect equipment from environmental damage by repairing or applying protective coatings to equipment. In addition to dealing with the weather, rig operators must take the necessary precautions to avoid potential explosions from the hazardous environments where they work.
Hazardous locations are areas where a potential for explosion and fire are a constant threat due to flammable gases, vapors, or finely pulverized dust in the air. Easily ignitable fibers or flyings might also pose a threat for explosion. Hazardous locations may result from the normal processing of certain volatile chemicals, gases, grains, or accidental failure of storage systems for these materials. Whatever the cause, it is necessary that every precaution be taken to guard against ignition of the atmosphere. So, what can a rig operator do to keep workers cool?
The explosion-proof models manufactured by Port-A-Cool portable evaporative cooling units can help rig operators meet this challenge. The 36-inch or 48-inch explosion proof/hazardous location models were specially developed by Port-A-Cool for use on offshore platforms. Electrical components can be a source of ignition for these hazardous location areas, but Port-A-Cool explosion proof models feature sealed switches, cords and motors to prevent sparking and accidental explosion in highly-combustible areas. In addition, the unit housings are rotationally molded and are leak and rust proof, preventing the rust and deterioration found in metal cooling systems.
The 36-inch explosion proof model is a best seller. cools 2,500 square feet and delivers 9,600 CFM. The 48-inch explosion proof model cools a large 4,000 square feet, delivers 17,500 CFM, and comes standard with heavy duty casters for extra mobility. Both models lower the temperature an average of 15 to 25°F.
