Typical Unit Specification
The air handler manufacturer shall furnish, install and place in operation, acceptable to the engineer, all
dehumidifier sections with flexible connectors, filters, volume dampers, control panel, and all necessary controls for proper operation of the system, as shown on contract drawings and as specified herein. The
dehumidifier section shall be arranged to provide continuous dehumidification with constant outlet temperature and humidity for a given inlet condition. The unit shall be a two compartment type using Brysorb Plus fluted desiccant media with process and regenerative sections. Dehumidifier cassette unit shall be as manufactured by Bry-Air Inc. VFB Series "Model VFB________ " as shown on the plans. B. DEHUMIDIFIER Dehumidifier section shall be capable of sustained operation of either process air flow or react air flow without energized reactivation heat for prolonged periods of operation without damage to the humidity transfer media. The
dehumidifier cassette shall be a fully automatic factory assembled unit, complete with desiccant rotor, desiccant rotor drive assembly, reactivation heat source, reactivation inlet filters, reactivation fan and motor, access panels, volume damper, _____________ (dust-tight or weatherproof) electrical enclosure, and all component auxiliaries as recommended by the manufacturer for safe, unattended automatic operation. Unit casing shall be constructed of continuously welded 0.125" thick aluminum to insure air and vapor tight construction. Air plenums and ducts shall be constructed of .080 or .125 solid welded aluminum. Easy-to-remove 0.125" thick aluminum access panels with vapor proof gasketing shall allow for simple service and inspection. Process insulation to be foil faced polyisocyanurate foam with an insulating R-value of not less than 6.5 per inch of thickness. Reactivation insulation shall be high temperature glass fiber with foil liner. The unit shall have weather and U.V. resistant paint over the exterior for corrosion protection. Independent pressure gauges for indication of process and reactivation air flow rates shall be included. Gauges shall have the normal operating range of the unit at approximately the midpoint of the gauge scale. Unit shall not require field piping, desiccant charging, pneumatics, or field erection of fans unless
