| Desiccant Dehumidifier Units - Shall be provided with the following capabilities, features, and specifications: |
| YES |
| NO |
Must be capable of outputting a minimum of 200 cubic feet per minute (CFM) and a maximum of 400 CFM of heated air at 0.24 inches of water +0.02 to -0.01 external static pressure.
Unit shall have a minimum of 2(ea.) blowers (i.e. inlet & outlet).
Unit shall have an electronic humidity sensor with digital display.
Unit’s heater element shall be positive temperature coefficient style heating elements, 1.75KW @ 440V.
Electrical Requirements: Power requirements for the dehumidifier are 440 Volt / 3 Phase / 60 Hz as supplied through remote disconnect with a current rating of not less than 4.7 amps.
Unit shall be provided with electrical circuit breaker.
Unit shall be provided with a pig tail with plug end IAW electrical requirements above.
Unit shall have at a minimum an “ON/OFF” switch with “POWER ON”, “UNIT RUNNING”, “HIGH HUMIDITY”, “HIGH TEMPERATURE”, “LOW AIRFLOW” indicator lights.
Unit shall have at a minimum manually set HIGH HUMIDITY set point and UNIT RUNNING set point controls.
All controls (i.e. ON/OFF switch and indicator lights) shall be mounted on the unit.
Inlet and outlet must be 4” flanged.
