The cooling tower efficiency of the Energy Recovery Unit evaporative cooler is a breakthrough for the low wet bulb temperature regions, says the company. The ERU 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 perform up to 100 percent efficiency. For colder climates, the ERU can be fitted with cross flow, heat pipe, or heat wheel exchangers as required by individual applications.
