Quest 70 Overhead Dehumidifier – 26L/Day | 230V 50Hz

Quest 70 Overhead Dehumidifier is a compact, professional dehumidifier designed for reliable humidity management in indoor growing areas, drying rooms, storage spaces and other controlled environments. Combining efficient moisture removal with a compact footprint, the Quest 70 can be positioned on the floor or suspended overhead to maximise usable space.

The UK-compatible 230V, 50Hz Quest 70 removes up to 26 litres of moisture per day at 26.7°C and 60% relative humidity, while consuming just 480 watts under the manufacturer's stated test conditions.

Featuring MERV-13 filtration, continuous drainage, onboard humidity controls and flexible installation options, the Quest 70 provides commercial-grade humidity control in a remarkably compact unit.

Key Features & Benefits

  • 26 litres per day moisture removal: Rated at 26.7°C and 60% RH.
  • Energy efficient: Published efficiency of approximately 2.22 litres per kWh.
  • Low power consumption: Rated at 480W with a 2.1A current draw.
  • 230V / 50Hz UK-compatible model: Designed for international electrical supplies.
  • Compact dimensions: Approximately 31cm wide × 31cm high × 54cm long.
  • Overhead installation: Compatible hanging accessories allow valuable floor space to be retained.
  • Freestanding option: Can also be positioned at floor level where appropriate.
  • MERV-13 filtration: Helps remove airborne particulates as air passes through the unit.
  • Continuous drainage: Condensate is discharged through a dedicated drain connection.
  • Wide operating range: Designed to operate between 5°C and 35°C.
  • Compact commercial construction: Ideal where powerful dehumidification is required without a large equipment footprint.

26 Litres Per Day Moisture Removal

The Quest 70 is rated to remove 26 litres of water per day at 26.7°C and 60% relative humidity.

This makes it well suited to environments where plants, irrigation, drying processes or other sources continuously add moisture to the surrounding air.

As with all refrigerant dehumidifiers, actual extraction performance varies according to room temperature and relative humidity. Warmer, more humid air generally allows greater water removal than cooler or drier conditions.

Efficient Humidity Control

Quest rates the 50Hz Quest 70 at approximately 2.22 litres of water removed per kWh under its published test conditions.

The unit consumes approximately 480 watts and draws only 2.1 amps, helping provide effective humidity management without placing excessive demand on the electrical supply.

Proper dehumidifier sizing remains important. Choose equipment according to the amount of moisture entering the environment rather than simply the room's floor area.

Ideal for Indoor Growing Environments

Controlling relative humidity is an important part of maintaining a stable indoor growing environment. Plants release substantial quantities of moisture through transpiration, particularly as foliage develops and irrigation rates increase.

The Quest 70 helps remove excess airborne moisture so growers can maintain more consistent environmental conditions.

It can be particularly useful in:

  • Indoor grow rooms
  • Hydroponic growing environments
  • Propagation and nursery areas
  • Drying rooms
  • Storage areas
  • Commercial horticultural spaces
  • Other humidity-sensitive indoor environments

Overhead or Floor-Standing Installation

One of the main advantages of the Quest 70 is its compact format and flexible installation.

The unit can be used as a conventional freestanding dehumidifier or suspended overhead using a compatible Quest 70 Hanging Kit.

Overhead mounting can be particularly useful in indoor growing environments where floor space is already occupied by plants, irrigation systems, reservoirs and other equipment.

Please Note: Hanging hardware is available separately unless specifically included with your chosen package.

Optional Ducting

A compatible Quest 70 Duct Kit can also be used where air needs to be drawn from or discharged into a particular part of the room.

Ducting can help provide greater flexibility when positioning the dehumidifier away from the main growing or working area.

Keep duct runs appropriately sized and follow Quest's installation instructions to avoid restricting airflow.

MERV-13 Air Filtration

The Quest 70 incorporates a MERV-13 air filter measuring approximately 23cm × 28cm × 3cm.

The filter helps capture airborne particles as room air passes through the dehumidifier while also helping protect the internal components from contamination.

Check and replace the filter regularly. Restricted airflow caused by a dirty filter can reduce performance and place unnecessary strain on the equipment.

Continuous Condensate Drainage

Water removed from the air is discharged through a 3/4-inch threaded NPT drain connection.

The condensate line should be routed to an appropriate drainage point according to the manufacturer's installation instructions.

Where gravity drainage is not possible, a suitable condensate pump may be required.

Wide Operating Temperature Range

The Quest 70 is designed to operate within temperatures of approximately 5°C to 35°C, giving it a broad operating range for different controlled environments.

For effective humidity control, excessive outside-air infiltration or water ingress should be addressed before relying on the dehumidifier.

Compact Commercial Dehumidification

At only 31 × 31 × 54cm, the Quest 70 provides significant moisture-removal capability from a compact enclosure.

Its 25kg weight and overhead-mounting capability make it particularly useful where larger floor-standing dehumidifiers would take up valuable working or growing space.

Maintenance

Regular maintenance helps keep the Quest 70 operating efficiently.

  • Check the MERV-13 filter regularly.
  • Replace dirty or restricted filters.
  • Keep air intake and discharge areas unobstructed.
  • Check the condensate drain and hose for restrictions.
  • Keep the unit clean and dry.
  • Have refrigeration and electrical servicing completed by suitably qualified personnel.
