The choice for desiccant dehumidification
Typical Unit Specification
Contractor shall furnish, install and place in operation, acceptable to the engineer, all
dehumidifier units 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 unit 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 desiccant media with process and regenerative sections. Dehumidifier unit shall be as manufactured by Bry-Air, Inc. MiniPAC Series "Model MP-_____" as shown on the plans. B. DEHUMIDIFIER Unit shall be capable of sustained operation of either process or react fan without energized reactivation heat for prolonged periods of operation without damage to the humidity transfer media. The
dehumidifier shall be a fully automatic factory assembled package unit, complete with reactivation heaters, filters, motors, fans, desiccant rotor and rotor drive assembly, access panels, volume dampers, automatic electrical panel, and all component auxiliaries as recommended by the manufacturer for safe, unattended automatic operation. Unit casing shall be constructed of 18 gauge steel to ensure air and vapor tight construction. Air plenums and ducts shall be constructed of 18 gauge steel. Easy-to-remove access panels with vapor proof gasketing shall allow for simple service and inspection. The unit shall have a high grade industrial powder coated finish for corrosion protection. Unit shall not require field piping, pneumatics, or field erection of fans unless specifically requested by the engineer. Field connection of the utilities shall be performed by the installation contractor. The
dehumidifier desiccant shall consist of high efficiency Brysorb fluted desiccant media in a horizontal rotor with a stainless steel rim mounted on a vertical fixed shaft arrangement. The media shall be adsorbent, non-toxic, non-corrosive and non-flammable. An observation window shall be provided to permit visual inspection of the rotor while the unit is in operation. Both reactivation air fan and process air fan shall be factory mounted on the
dehumidifier. The reactivation and process air fans shall be arranged to provide counter-flow air streams.
