DP-CD1131 350-PPD Dehumidifier for Large-Loss and Industrial Drying

The DP-CD1131 removes up to 350 PPD (176 PPD AHAM at 80°F/60% RH) and moves 750 CFM across spaces up to 30,000 sq ft. A built-in pump lifts condensate 16.4 ft, backed by a 2-gallon tank and a 3.28 ft gravity hose. Its 176 PPD AHAM rating clears the LGR threshold that maps to Xactimate code WTRDHM>XL. It draws 1450W on a 220V circuit.

350 PPD, 750 CFM, and 16.4-Ft Pump Lift

  • 350 PPD moisture removal (176 PPD AHAM) — top-of-range output for the largest water losses and warehouse humidity control, with 420 PPD at saturation
  • 750 CFM airflow across 30,000 sq ft — single-unit coverage for distribution centers, gymnasiums, and industrial floor plates
  • 16.4-ft pump lift — continuous automatic drainage to elevated sinks, windows, or drain lines
  • 2-gallon tank and 3.28 ft gravity hose — a gravity drain runs alongside the pumped removal for flexible setup
  • 10–90% RH control, 41–95°F range — holds setpoint from flood drying down to maintenance humidity
  • R32 refrigerant with rotary compressor — 1450W (220V/6.8A) draw with auto-restart, auto-defrost, and overload protection
  • Steel housing, 60 dB single-speed fan — washable filter and industrial-grade chassis for long-term deployment

DP-CD1131 Applications and Environments

Large-loss restoration contractors specify the DP-CD1131 for commercial water losses in big-box retail, school gymnasiums, and hospital wings, where a single high-capacity unit cuts equipment deployment logistics and the 176 PPD AHAM rating supports Xactimate WTRDHM>XL billing. Cold-storage managers deploy it in staging and receiving areas where repeated door openings drive sustained high humidity through warm months. Manufacturers run it in production areas where humidity above 50% RH causes failures in coatings, adhesives, and precision assembly. Convention centers and event venues use it for humidity management in large exhibit halls during high-dew-point periods. The 750 CFM airflow and 30,000 sq ft rating are what let one DP-CD1131 stand in for several smaller units on a large loss, which cuts the number of machines a crew has to haul, power, and monitor on site. It draws 1450W on a 220V circuit rather than a standard 115V outlet, so confirm the receptacle before deployment. The 16.4-ft pump lift drains continuously to an overhead line, backed by the 2-gallon tank and gravity hose for setups where a pumped run does not reach. Auto-restart, auto-defrost, and overload protection keep it running unattended through the long duty cycles these jobs demand. The unit measures 25.5 × 16.9 × 62 in, weighs 183 lb, and is backed by a 1-year parts and labor warranty.

Frequently Asked Questions

How many gallons per day does 350 pints represent?
350 pints equals 43.75 gallons of water removed per day — approximately 1.8 gallons per hour at rated capacity. This is one of the highest portable dehumidifier outputs available in a single commercial unit.
What type of commercial water loss events require a 350-pint dehumidifier?
Large Category 1–2 commercial losses covering 3,000–6,000+ square feet of wet materials — flooded gymnasium floors, retail store slab-on-grade water intrusion, or multi-office floor commercial pipe breaks — typically specify a 350-pint unit as the primary dehumidifier.
How does the DP-CD1131 compare to the DP-CD1130 (290 PPD)?
The DP-CD1131 removes 60 more pints per day and covers 6,000 more square feet than the DP-CD1130. Both use a built-in pump and dual-speed fan. The DP-CD1131 is the better choice for very large floor plates or high-moisture-load environments.
Can mold grow while this unit is running?
Mold requires relative humidity above approximately 60% RH to grow. If the DP-CD1131 maintains the environment below 50% RH, new mold growth is effectively inhibited. However, it does not remediate existing mold — only prevents new colony development.
Does continuous 24/7 operation at 350 PPD create heat?
Yes. All dehumidifiers generate heat as a byproduct of the refrigeration cycle — typically 10–15°F above ambient. In enclosed spaces, this heat accumulation can increase ambient temperature and slightly reduce dehumidification efficiency. Ventilation or air conditioning in conjunction with dehumidification is recommended for temperature-sensitive restoration jobs.
What circuit amperage does the DP-CD1131 require?
Contact us or review the product spec sheet for exact amperage draw. High-capacity commercial dehumidifiers in the 290–350 PPD range typically require a 15–20 amp dedicated circuit at 115V. Do not share a circuit with other high-draw restoration equipment.
Is the DP-CD1131 suitable for outdoor or semi-outdoor use?
The DP-CD1131 is rated for indoor commercial use. Use in semi-outdoor environments such as covered loading docks is possible if ambient temperature stays within the 41°F–95°F operating range, but prolonged exposure to rain or direct moisture is not recommended.
