Evair® Dehumidification System

DriSteem’s refrigerant-based dehumidifiers are an excellent fit for any commercial application requiring capacity from 100 pints / day to 710 pints / day @ 80°F, 60% RH

DriSteem offers a full line of refrigerant dehumidifiers to take on humidity in any size application, in a variety of environments such as storage, manufacturing, retail, education, water treatment facilities, and more. The RQ Series represents the highest‑efficiency platform in the lineup, delivering maximum moisture‑removal capacity per kWh while maintaining performance across the widest operating temperature range.

Our innovative design also creates the lightest heat load on your HVAC, pulls less energy, saving money on utility bills, and helps to prevent overload on your state’s energy grid, often qualifying you for energy rebates. The compact mechanical design provides increased capacity within a smaller physical footprint, supporting more efficient space utilization in both retrofit and new‑construction applications.

The RQ series digital control panel delivers precise humidity management with:

    Adjustable RH setpoints in 1% increments
    Filter change and defrost notifications for easier maintenance
    Self-diagnostics to speed up service and reduce downtime
    Dark Mode for reducing light in sensitive environments
    Low voltage terminal block for optional external control connection,
    ideal for overhead installations

Maintaining a controlled environment will:

    Prevent damage to sensitive instruments in processing environments
    Support the plant grow cycle for indoor agriculture such as cannabis
    Minimize the risk of equipment failure in manufacturing facilities
    Preserve important materials and artifacts in storage space and museums
    Safeguard against the spread of viruses and bacteria in dry storage and warehouses
