SSfcg^s^/IP2'®(oI\B®(^© Hai£'S@'iaIlftm5^© RUBBAIR DOOR REPRESENTATIVES WILL CALCULATE ENERGY SAVINGS RubbAir Door Division, Ayer, Mass., announces the availability of their new, free energy audit service of having a factory-trained repre- sentative inspect your building to determine the potential energy sav- ings that RubbAir Doors can pro- vide. These computations will include the typical loading dock/receiving area for heat loss in the winter and also the newest applications for shock absorbing, insulated traffic doors: walk-in cooler boxes. The RubbAir Door representa- tive is trained and equipped with tables, data and an energy slide rule computer to calculate the energy consumption for heat or refrigera- tion for each opening, factoring important components such as humidity, air velocity and cost of fuel to provide energy consumption figures three (3) methods: millions of BTU loss per hour; cost of fuel loss; BTU loss per square foot. Refrigeration savings are based on common box temperatures rang- ing from 45° to -20° F. and prove that when RubbAir Doors are used in coolers, it is one of the best temperature and money saving ideas you'll ever bump into. An added feature of the audit service is a noise attenuation chart for determining the effective sealing and sound absorbing characteristics of RubbAir Doors. RubbAir Doors are custom built traffic doors used for all applica- tions and, even after 25 years, these doors are still "hanging in" for customers and meeting their envir- onmental control needs. All doors are individually fabricated accord- ing to customers choice of model, window, color and features, de- pending on each application. Presently there are over 160 de- signs. The doors and the door energy audit service are available for all types of uses from food processors to supermarkets to industry.
