Quest 200 50Hz Dehumidifier – 90L/Day Commercial Humidity Control

Quest 200 50Hz is a high-performance commercial dehumidifier designed for demanding humidity-control applications. Delivering powerful moisture removal, high energy efficiency and flexible installation options, it is ideal for indoor growing environments, drying rooms, commercial horticultural facilities, storage areas and other controlled spaces.

Rated to remove 90 litres of water per day at 26.7°C and 60% relative humidity, the Quest 200 provides substantial dehumidification capacity while achieving an energy factor of 3.9 litres per kWh.

Powered by Quest's patented M-CoRR® multi-coil technology, the Quest 200 combines efficient refrigeration performance with a compact footprint, onboard digital controls, MERV-13 filtration and built-in hanging points for straightforward overhead installation.

Key Features & Benefits

90L/day moisture removal: Rated at 26.7°C and 60% RH.
High energy efficiency: Delivers 3.9 litres of moisture removal per kWh under rated conditions.
Patented M-CoRR® technology: Multi-coil refrigeration recovery improves dehumidification efficiency.
500 CFM airflow: High-volume air movement for consistent humidity control.
Digital onboard controls: Fine-tune humidity setpoints in 1% increments.
MERV-13 filtration: Helps capture dust, pollen, mould particles and other airborne contaminants.
Integrated hanging points: Suitable for overhead installation without a separate hanging kit.
Freestanding or overhead placement: Flexible installation to suit different environments.
Dark Mode: Turns off display lighting for light-sensitive environments.
Auto restart: Returns to previous settings after a power interruption.
External control compatible: Includes a low-voltage terminal block for compatible controllers.
Maintenance alerts: Includes filter-change reminders and system-status indicators.
3-year limited warranty: Manufacturer-backed professional equipment.

90 Litres Per Day Moisture Removal

The Quest 200 50Hz is designed for environments where large amounts of moisture need to be removed continuously.

At 26.7°C and 60% relative humidity, it removes up to 90 litres of moisture per day. At the lower test condition of 23.9°C and 50% RH, Quest rates the unit at 57.7 litres per day.

This makes the Quest 200 particularly suitable for environments where irrigation, plant transpiration, drying processes or other activities continually add moisture to the surrounding air.

High-Efficiency M-CoRR Technology

Quest's patented M-CoRR® Multi-Coil Refrigeration Recovery technology is designed to improve the efficiency of the refrigeration process.

Rather than relying on a conventional coil arrangement, the system uses a multi-coil configuration to recover and reuse energy within the dehumidification cycle.

At rated conditions, the Quest 200 achieves an energy factor of 3.9 litres per kWh, helping reduce running costs while maintaining high moisture-removal capacity.

Designed for Indoor Growing Environments

Controlling humidity is an important part of maintaining a stable indoor growing environment. Plants continuously release moisture through transpiration, particularly as plant size and irrigation rates increase.

The Quest 200 removes excess moisture from the air, helping growers maintain more consistent environmental conditions and reduce large humidity fluctuations.

Suitable applications include:

Indoor grow rooms
Hydroponic growing facilities
Commercial horticultural environments
Propagation and nursery areas
Drying rooms
Storage spaces
Climate-controlled commercial facilities

Digital Onboard Humidity Control

The Quest 200 features a modern onboard digital control system designed for straightforward operation and accurate adjustment.

Humidity setpoints can be adjusted in 1% increments, allowing the user to fine-tune the target relative humidity for the environment.

The digital control system includes:

Precise RH setpoint adjustment
Visual defrost indicators
Self-diagnostic feedback
Filter-change reminders after 2,000 fan hours
Auto and continuous fan modes
Optional Dark Mode
24V external control capability

Dark Mode

The built-in Dark Mode disables the display lights while allowing the dehumidifier to continue operating normally.

This makes the Quest 200 particularly useful in light-sensitive growing environments where unnecessary light from control panels may be undesirable.

MERV-13 Air Filtration

The Quest 200 uses a MERV-13 air filter measuring approximately 45.7 × 45.7 × 5.1cm.

The filter helps capture airborne particles as air moves through the dehumidifier while also protecting internal components from dust and contamination.

Quest recommends regular filter inspection and replacement to maintain maximum performance. The onboard control system provides a filter reminder after approximately 2,000 fan hours.

500 CFM Airflow

The Quest 200 moves approximately 500 CFM of air through the unit.

High airflow helps circulate humid air through the dehumidifier efficiently, allowing moisture to be removed continuously from the surrounding environment.

Integrated Hanging Points

The current Quest 200 features integrated lift and hanging points, eliminating the need for a separate hanging kit.

For overhead installation, Quest specifies the use of suitable 3/8-inch threaded rod installed directly into the built-in mounting points.

This makes overhead installation simpler while helping maximise valuable floor space.

Important: Any overhead support structure must be capable of safely supporting the full installed weight of the dehumidifier. Use suitably rated fixings and follow Quest's installation instructions.

Freestanding or Overhead Installation

The Quest 200 can be positioned directly on the floor or suspended overhead depending on the layout of your room.

Overhead mounting is particularly useful where floor space is occupied by plants, reservoirs, irrigation equipment or other climate-control equipment.

Continuous Condensate Drainage

The Quest 200 uses a 1.9cm / 3/4-inch threaded NPT drain connection for continuous condensate removal.

The drainage system should be installed according to Quest's current installation instructions, including the correct P-trap arrangement where required.

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

Operating Temperature Range

The Quest 200 is designed to operate between approximately 13°C and 35°C.

For best performance, ensure airflow around the unit is unrestricted and excessive outside-air infiltration or uncontrolled water ingress is addressed.
