Namco P649 330-Pint Commercial Dehumidifier – Auto Pump, Digital Controls, R-410A

Namco P649 330-Pint Commercial Dehumidifier with Auto Pump-Out

The Namco P649 removes up to 330 pints of moisture per day using R-410A refrigerant with an automatic pump-out system that continuously drains collected water without manual emptying. Digital controls allow humidity setpoint selection with real-time display. At the 330-pint capacity class, the P649 targets large commercial spaces, industrial facilities, and serious flood remediation where smaller-capacity units cannot keep pace with moisture load.

P649 Moisture Removal Capacity, Refrigerant, and Controls

• Capacity: 330 pints/day — high-volume moisture extraction for large warehouses, industrial spaces, and post-flood environments with heavy structural moisture.
• Refrigerant: R-410A — modern refrigerant with no ozone depletion potential; commonly specified in commercial HVAC and dehumidification equipment.
• Auto pump-out — continuous water removal without manual bucket emptying; connects to standard drain line.
• Digital controls with LCD display — set target humidity level (typically 50–60% RH for structural drying) and monitor current conditions.
• Max operating temperature: 105°F — works in warm, humid environments including sun-exposed storage areas and summer-temperature basements.
• Power: 6.75A at 110–125V — runs on standard commercial outlets without dedicated circuit requirements.
• Dimensions: 22" × 20" × 40" — positioned on wheels for repositioning between areas.

Industrial and Commercial Moisture Removal Applications

330-pint dehumidifiers target environments where ambient moisture load exceeds what smaller consumer-grade units (50–150 pints/day) can manage: active flood remediation sites, large cold storage areas with condensation problems, industrial facilities with process moisture generation, and large basements or crawl spaces with chronic groundwater infiltration. The auto pump-out eliminates the labor cost of bucket emptying that makes manual-drain units impractical in continuous 24/7 operation. For water damage restoration (WTRDHM billing category), the P649's capacity places it in the large commercial dehumidifier class for Xactimate estimating purposes.

Dual Functionality as Dehumidifier and Dryer

At 330 pints/day, the P649 functions as both a dehumidifier (maintaining target relative humidity) and a structural dryer (rapidly reducing elevated moisture in walls, floors, and contents after a flooding event). In restoration contexts, the machine is placed in the affected space immediately after water extraction and run continuously until moisture meter readings in affected structural materials return to normal range—typically 8–12% moisture content in wood, under 0.5% in concrete. The LCD setpoint display allows contractors to set and document target conditions for insurance claim records.
