An airconditioning specialist can evaluate the entire facility to estimate the size and number of cooling units needed, with average temperatures and air quality factored in. Soper stated that the searing temperatures at Breinigsville negatively affected the workers, who often had to walk the equivalent of ten miles every day just to get items from the many shelves. The OHSA inspections in June, 2011 prompted the temporary installation of three 440-ton screw chillers; however, the machines were not powerful enough for the entire facility. Consultations with your Ontario air conditioning contractor can determine where to install new or replacement commercial-grade air conditioners. An industrial engineer familiar with the Breinigsville project said that the facilityâ¤™s new airconditioners were airlifted by helicopter and carefully set up. The machinesâ¤™ potential cooling loads were unknown.
