High-Efficiency Portable Dehumidification for Demanding Grow Environments

The Quest Hi-E Dry 140 Portable Dehumidifier removes 135 pints of moisture per day at 110-120V, drawing only 6.8 amps for exceptional energy efficiency. Delivering 300 CFM of airflow and 8,850 BTU of thermal capacity, it handles serious humidity loads without monopolizing your electrical panel. MERV 10 filtration captures dust, mold spores, pollen, and other airborne contaminants to keep your grow environment clean and healthy. With integrated handles and a compact footprint, the Hi-E Dry 140 moves easily between grow rooms, drying chambers, or wherever humidity control is needed most - and auto-restart after power outages keeps conditions stable around the clock.

Key Features & Benefits

• 135 Pints/Day Moisture Removal - High-capacity dehumidification precisely manages relative humidity to minimize mold, mildew, and pathogen pressure in your grow environment.
• MERV 10 Air Filtration - Captures dust, pollen, mold spores, and contaminants to maintain healthier air quality without restricting system airflow.
• 110-120V Plug-and-Play Operation - Standard outlet connection allows flexible placement anywhere in your facility without dedicated wiring or installation.
• Low 6.8-Amp Draw - Energy-efficient 780-watt operation leaves headroom on your panel for lighting, irrigation, and other critical equipment.
• Portable Design - Integrated handles and compact form factor make it easy to reposition between grow rooms, drying chambers, or wherever dehumidification is needed most.
• Auto-Restart - Automatically resumes operation after power outages, maintaining your humidity setpoints without manual intervention.
• R454B Refrigerant - Uses environmentally preferred lower-GWP refrigerant consistent with current sustainability standards.

Who Should Use This

The Quest Hi-E Dry 140 is ideal for cultivators who need flexible, high-capacity humidity control without permanent overhead installation. Perfect for grow rooms, drying and curing spaces, propagation areas, and operations where portability is an advantage. The low amp draw makes it suitable for both residential and commercial grow setups running on standard circuits.

Compatibility

Requires a standard 110-120V outlet with adequate amperage. Compatible with Quest digital humidistats and environmental controllers for integrated humidity management. MERV 10 replacement filters available separately. Supports gravity drain via included hose connection; use with an external condensate pump when routing water uphill or over longer distances.

Frequently Asked Questions

Does the Hi-E Dry 140 include an onboard humidistat?

The Quest Hi-E Dry 140 includes onboard humidity controls for setting your target relative humidity. For centralized management, it pairs with Quest digital humidistats and wall controllers available separately.

How do I drain collected water continuously?

The unit supports continuous gravity drain via a hose connection, eliminating manual bucket emptying. An external condensate pump is recommended when drain lines need to run uphill or over longer distances for uninterrupted 24/7 operation.

How often should I replace the MERV 10 filter?

In typical grow environments, inspect the filter monthly and replace every 1 to 3 months depending on particulate load. Regular filter maintenance ensures consistent airflow and dehumidification performance.

Can this unit run 24/7 in a commercial grow room?

Yes - the Quest Hi-E Dry 140 is engineered for continuous commercial operation. Auto-restart and durable construction ensure reliable round-the-clock performance in demanding cultivation environments.
