CASTING INNOVATIONS
operators excellent control over the airflow. Te fan runs at 9200 CFM (260.50 CMM), and creates a long, directed airstream which then slowly disperses in the same general direc- tion. Te long-ducted fan enhances airflow and control, which standard open-face fans don’t. Most industrial fans on the
market are engineered with a short outer shell large enough to house the motor and sizeable fan blades, protected by a mesh cage on either end. Some mod- els do away with the metal shell altogether and only have a mesh cage. These units disperse air in a wide pattern, creating a breeze over a large area. This method is effective for generating broad cir- culatory airflow or cooling when directed at specific stations, but has difficulty precisely directing
airflow over extended distances. Trace Die Cast set cannons at
both entrances and pointed them at each other to create an airstream down the central aisle. That created positive flow from the ground. Te KoolBoss is designed with
a powerful 7.5 horsepower fan, set in the rear of a specially engineered cone-shaped steel barrel, with the fan blades shielded by a heavy mesh guard. Te unit draws air from the wide opening in the tail and forces it down the cone toward the narrower mouth in front, where the shape increases the air velocity and directs the discharge. Either mounted on a mobile car-
riage or a square steel tube skid, the golf-cart sized unit weighs approxi- mately 800 lbs. (363 kg) and can be relocated where needed. The units were run 24/7 over
a three-month period, without disruption and with only the oc-
casional position adjustment. The units pulled air from the entrances and delivered a strong airflow that extended down the length of the work aisle and prevented hot air from forming into pockets, boost- ing positive flow out of the roof vents. The circulation lowered the overall temperature of the facility and created a more controlled and comfortable work environment. That raised morale and made work stations more pleasant. Te warmth of the summer
started earlier and ended later than predicted, so operators report their rental period would have been even longer if the forecast had been more accurate. Trace Die Cast is budgeting to purchase a unit.
