The Commercial Dehumidifier 90L 138L is a high-capacity environmental control system designed for research facilities requiring precise humidity management. This unit removes up to 90 liters of moisture per 24-hour period while maintaining adjustable humidity levels between 10% and 90% relative humidity across areas up to 150 square meters.
Built with cold rolled plate coating construction and utilizing R410A refrigerant, this dehumidifier provides reliable environmental control for laboratories, storage areas, and research facilities where consistent humidity conditions are critical for experimental protocols and equipment protection. The unit operates on standard laboratory power requirements with optional voltage configurations to accommodate different facility specifications.
How It Works
This commercial dehumidifier operates on the refrigeration principle using R410A refrigerant to condense water vapor from ambient air. The system draws humid air through an evaporator coil where moisture condenses as the air temperature drops below its dew point. The condensed water is collected in a reservoir while the dried air passes over a condenser coil to return to room temperature before being circulated back into the environment.
The unit maintains precise humidity control through an integrated sensor system that monitors ambient relative humidity levels and automatically cycles the refrigeration system to maintain setpoint conditions. The adjustable range of 10% to 90% relative humidity allows researchers to establish specific environmental conditions required for their protocols or equipment specifications.

Practical Tips
Verify humidity sensor accuracy using calibrated reference instruments at multiple setpoints within your operating range.
Why: Sensor drift over time can affect environmental control precision for sensitive experiments.
Clean air intake filters monthly and inspect condensate drainage for blockages during routine facility maintenance.
Why: Restricted airflow reduces dehumidification efficiency and can cause system cycling problems.
Position unit away from heat sources and ensure adequate air circulation around intake and exhaust vents.
Why: Proper airflow maximizes the effective coverage area and prevents hot spots that reduce efficiency.
If humidity control becomes erratic, check for air leaks in the controlled space and verify drainage system function.
Why: External humidity sources and drainage problems are common causes of apparent equipment malfunction.
Monitor both inlet and outlet air conditions to verify system performance matches facility requirements.
Why: Independent monitoring confirms the unit is achieving target conditions across the full coverage area.
Ensure electrical connections match the unit's voltage requirements (220V/50Hz or 110V/60Hz) and provide appropriate circuit protection.
Why: Incorrect voltage can damage the refrigeration system and create safety hazards.

Compliance
What is the humidity control accuracy and response time for setpoint changes?
The unit maintains adjustable humidity between 10-90% RH with automatic cycling. Consult product datasheet for specific control accuracy and response time parameters.
How does the 1300W power consumption compare to facility electrical capacity requirements?
The unit draws 1300W on either 220V/50Hz (standard) or 110V/60Hz (optional) power systems. Verify facility circuit capacity can support continuous operation at this load level.
What maintenance schedule is required for the R410A refrigerant system?
R410A systems typically require annual professional service for refrigerant level checks and coil cleaning. Follow manufacturer maintenance protocols for optimal performance.
Can multiple units be coordinated for larger facility coverage beyond 150 square meters?
Each unit covers 90-150 square meters independently. Multiple units can be installed for larger areas, though coordination systems may require separate environmental controls.
How does ambient temperature affect the 90L/24H removal capacity?
Dehumidification capacity varies with ambient temperature and initial humidity levels. Consult product datasheet for capacity curves at specific operating conditions.
What condensate drainage options are available for continuous operation?
The unit requires drainage system for the 90L daily condensate removal. Options include gravity drain connections or condensate pumps for facilities without floor drainage.
Is the cold rolled plate coating compatible with laboratory chemical environments?
Cold rolled plate coating provides corrosion resistance for typical laboratory environments. Evaluate compatibility with specific chemical exposures in your facility.
