Benefits<br />

� Extends the application of mechanical<br />

(vapor-compression) cooling equipment<br />

• Lowers achievable dew point by 5°F to 10°F<br />

� Uses less energy than cooling plus reheat<br />

• Less cooling tons, no reheat, warmer coil temperature<br />

� Does not require a separate exhaust airstream<br />

• It is NOT exhaust-air energy recovery<br />

� Typical applications: zones that require lower dew<br />

points (surgery rooms, supermarkets, laboratories,<br />

pharmacies, libraries, museums, archive storage)<br />
