Who This Is For

  • You are sourcing high-voltage units because your 277V facility wiring limits your choice of standard plug equipment.
  • You are prioritizing M-CoRR tech because your cooling system cannot handle the extra heat load from older dehumidifiers.
  • You are installing overhead units because floor space is at a premium and you need clear walkways for crop maintenance.

What We Found

  • The 277V model is what we recommend when you need to keep your limited 120V circuits free for lighting and fans.
  • The MERV 13 filter is a massive step up for keeping the internal coils clean compared to standard MERV 11 setups.

What Users Say

  • Facility managers who switched to 277V say they stopped tripping breakers when all their equipment runs at once.
  • Operators tell us the overhead mounting freed up floor space they desperately needed for more tables and walkways.

Quest 335 277V Industrial Dehumidifier — 345 Pints/Day

Struggling to manage humidity in a commercial facility with 277V infrastructure? The Quest 335 277V Industrial Dehumidifier is engineered specifically for this challenge, delivering powerful moisture removal that integrates perfectly with your existing electrical systems.

This high-efficiency unit removes up to 345 pints of moisture per day with an impressive 8.0 pints per kWh rating, making it one of the most efficient industrial dehumidifiers on the market. Its patented M-CoRR™ multi-coil technology recycles excess heat, boosting efficiency while reducing the heat load in your space.

Engineered for continuous operation, the Quest 335 runs effectively in temperatures from 56°F to 95°F. It features integrated MERV 13 filtration that captures mold spores, dust, and other airborne contaminants, which is 20% more effective than MERV 11 filters.

Proudly assembled in Madison, Wisconsin, this plug-and-play unit includes onboard digital controls and an energy-saving variable speed fan. The 277V configuration draws only 6.3 amps, freeing up electrical capacity for other equipment. If your facility uses a different voltage, consider the powerful Quest 335 208/230V model.

FAQs

How do I know if this is the right size dehumidifier for my space?+

Sizing a dehumidifier depends on your room size, plant count, and target humidity. The Quest 335 is a high-capacity unit ideal for large commercial spaces. For a detailed breakdown of different models and how to choose the right one, check out our complete guide to Quest dehumidifiers. For even larger areas, you might consider the Quest 876.

How does the Quest 335 277V's M-CoRR™ technology reduce facility cooling costs?+

The M-CoRR™ technology recycles excess heat during dehumidification, reducing the unit's heat output into your space. While removing 345 pints per day, it outputs only 21,500 BTUs total with just 5,800 BTUs from motor load. This lower heat output reduces the burden on your cooling system, lowering overall HVAC operating costs.

Why choose 277V over standard 208/230V dehumidifiers for my facility?+

The Quest 335 277V is ideal for commercial facilities that already have 277V outlets installed for lighting systems. The higher voltage operation draws only 6.3 amps compared to higher amperage requirements of lower voltage units. This frees up electrical panel space for other equipment and integrates seamlessly with existing 277V infrastructure.

How does the Quest 335 277V compare to the 208/230V version?+

The Quest 335 277V offers the same quality, features, and M-CoRR™ technology as the 208/230V version but is specifically configured for 277V electrical systems. Both units deliver identical performance (345 pints/day, 8.0 pints/kWh), but the 277V model is optimized for facilities with existing 277V infrastructure.

What makes the Quest 335 277V suitable for plug-and-play installation?+

The Quest 335 277V features onboard digital controls with an integrated dehumidistat, eliminating the need for external control installation in many applications. The unit comes with a 6-foot power cord with NEMA L7-15P plug for direct connection to 277V outlets. It also includes integrated handles for easy positioning.

How effective is the MERV 13 filtration compared to standard filters?+

The MERV 13 filtration is significantly more effective than lower-rated filters: 20% more effective than MERV-11 and 65% more effective than MERV-8. It captures harmful particulates including mold spores, dust, allergens, bacteria, and virus carriers while maintaining 900 CFM airflow.

What control options are available with the Quest 335 277V?+

The Quest 335 277V offers flexible control options, including onboard digital controls with an intuitive interface, an integrated dehumidistat for automatic humidity maintenance, and a low voltage terminal block for integration with building management systems.

What does the 5-year warranty cover?+

The Quest 335 277V includes a comprehensive 5-year manufacturer warranty covering defects in materials and workmanship. The unit is engineered and assembled in Madison, Wisconsin, providing direct manufacturer support and service for reliable operation in demanding commercial environments.
