Dehumidifier shall be of the non-cycling sorption type with a single desiccant, rotary structure. The casing shall be fabricated as a unitized body with welded aluminum construction for maximum strength and durability. Suitable access panels on both sides of the unit shall allow access for inspection or servicing without disconnecting ducting or electrical wiring. Airflow balancing dampers to be furnished. The dehumidifier shall be designed for continuous operation. The rotary structure shall be a monolithic fabricated extended surface composite consisting of inert silicates reinforced with uniform diameter glass fibers for maximum strength. The fabricated structure shall be smooth and continuous in the direction of air flow without interruptions or sandwich layers which restrict airflow or create a leakage path at joining surfaces. Desiccant shall not channel, cake or fracture due to repeated temperature and moisture cycling. The materials of construction shall be non-toxic. Design shall be modular in approach to readily allow connection to accessories such as face and bypass, pre- or post-cool modules. Electrical components shall be UL/CSA recognized and wiring methods in accordance with the latest edition of the National Electrical Code. Power supply shall be ___Volts/3Phase/___Hertz. Full face contact pressure seals shall be provided to separate the process and reactivation airstreams and eliminate detrimental leakage of air or moisture with static pressure differentials of up to 8" of water gauge. Dehumidifier shall be factory assembled, fully automatic, complete with laminar flow desiccant wheel, reactivation heaters, reactivation energy control system, roughing filters, motors, fans, non-ratcheting desiccant rotor drive unit, automatic controller and all components’ auxiliaries. Dehumidifier shall be functionally tested at the manufacturer's factory and shipped complete with all components necessary to maintain normal operation. *Continual engineering and research product improvement may result in design and specification changes.
