Namco P646 110-Pint Portable Commercial Dehumidifier with 50-Foot Drain Hose

The Namco P646 removes up to 110 pints of moisture per day with an automatic pump-out system and a 50-foot drain hose that allows drainage to a distant outlet without repositioning the machine. Digital humidity controls with an internal thermometer display real-time conditions and allow setpoint programming for continuous moisture management in water damage restoration and large commercial facilities.

P646 Capacity, Drain Hose Reach, and Control System

  • Capacity: 110 pints/day — commercial portable class suitable for large basements, warehouses, and water damage restoration sites.
  • Drain hose: 50 ft included — allows drainage to a distant floor drain or exit point without manual water handling or machine repositioning.
  • Auto pump-out — built-in pump pushes collected water through the 50-foot hose continuously without manual drain cycles.
  • Controls: digital LCD with internal thermometer — set target humidity level, monitor current humidity and temperature; programs humidity setpoints for automated control.
  • Max operating temperature: 105°F — operates in warm environments including sun-exposed areas and high-heat industrial spaces.
  • Power: 6.75A at 110–125V, NEMA 5-15P — standard residential/commercial outlet compatible.
  • Wheels included — repositions between areas without lifting.

Water Damage Restoration and Industrial Humidity Control Applications

The 50-foot drain hose is the key differentiating feature of the P646 portable. In water damage restoration environments, drain access points are often distant from the drying zone—a floor drain may be 30–40 feet away from the damaged area where the dehumidifier needs to be positioned. The 110-pint capacity combined with the long drain hose allows the P646 to be placed directly in the affected area and drain continuously without hose extension or repositioning. For industrial facilities managing process humidity or seasonal condensation, the 50-foot hose reach provides enough flexibility to position the machine optimally and route drainage to a permanent drain without custom plumbing.

Internal Thermometer and Humidity Setpoint Management

The P646's digital display provides simultaneous humidity and temperature readings, which is useful in restoration contexts where both metrics need documentation for insurance claims and IICRC S500 structural drying logs. Setting a humidity target of 50% RH in a water-damaged space allows the machine to cycle on and off automatically as conditions change, rather than running continuously regardless of moisture level. This reduces energy consumption during recovery drying and extends compressor life compared to machines without humidity control setpoints.

Frequently Asked Questions

How long is the drain hose included with the Namco P646?
The P646 includes a 50-foot drain hose. The built-in pump pushes collected water through the full 50 feet to a distant drain point without requiring the machine to be repositioned closer to the drain.
How much moisture does the Namco P646 remove per day?
The P646 removes up to 110 pints of moisture per day—commercial portable class suitable for large basements, warehouses, and water damage restoration sites.
Does the P646 display both temperature and humidity?
Yes. The P646's digital LCD displays real-time humidity and temperature readings simultaneously using the internal thermometer. This supports documentation requirements for IICRC S500 structural drying logs and insurance claims.
Can the humidity setpoint on the P646 be programmed?
Yes. The digital controls allow you to set a target relative humidity level. The machine cycles on and off automatically to maintain the setpoint, reducing energy consumption compared to units that run continuously without humidity control.
What is the difference between the P646 portable and the P646-95 crawl space model?
The P646 portable removes 110 pints/day and includes a 50-foot drain hose with a higher-powered pump system. The P646-95 removes 95 pints/day and uses a compact form factor for crawl space installation. The P646 portable is better suited for restoration work and large open areas.
What refrigerant does the Namco P646 use?
The P646 uses R-410A refrigerant—current standard with no ozone depletion potential, serviceable throughout the US.
