Resources ERU Catalog     Cooling tower efficiency of the Energy Recovery Unit evaporative cooler by United Metal Products is a breakthrough for the low wet bulb temperature regions. The low temperature cooling tower performance gives United Metal Products' Energy Recovery Unit an edge over any other air to air energy recovery unit. In the development of indirect evaporative cooling, United Metal Products has devised a method of transferring temperature at the lower wet bulb levels. The principle is simple. By exchanging temperature at the wet bulb, the energy recovery unit can increase efficiency up to 75% over a standard dry bulb exchanger. This means big savings for the building owner. Over the past 20 years, energy recovery strategies have largely been centered on sensible energy recovery at dry bulb temperatures. Although this works well in the colder climatic regions of the world, where one is concerned about heat loss, it has not been effective in areas where a higher dry bulb temperatures exist. The United Metal Products' ERU evaporative cooler can be manufactured in configurations of 2,000 to 80,000 CFM and be provided with options like chilled water coils, DX, gas heat ,single point power and control logic. In applications where energy recovery is needed for colder climates, the ERU can be fitted with cross flow, heat pipe or heat wheel exchangers as required by individual applications. A pplications Energy Recovery Units have the following benefits and features:      • Airports      • Clean Rooms      • Factories      • Hospitals      • Kitchens      • Prisons      • Terminals      • Call Centers      • Convention Centers      • Indoor Pools      • Offices      • Schools      • Theaters      • Casinos United Metal Products' Energy Recovery Units have the following benefits and features:      • 0-100% outside air      • 5,000 to 40,000 CFM and higher      • Production or custom design      • Package or split system      • Energy recovery: heat pipe, air to air, air to water, heat wheels      • Engineered primarily for high outside air requirements: 30%-100%      • Powder coated      • ETL - labeled under UL 1995      • Fabrication When the application requires high energy recovery, the ERU is the outside air solution. Rely on the cooling tower power and evaporative cooling efficiency in all applications with a low wet bulb level.
