The refrigerant system modulates the speed of dehumidification based on the precise load conditions of your grow environment, allowing for robust VPD performance across all grow conditions. The compact design keeps your dehumidifiers running during the challenging late flower stage where single-speed dehumidifiers require frequent defrost cycles. This increases capacity, efficiency, and most importantly, the stability of your grow environment.
The PREAIR ZETA series is the best investment across all grow conditions compared to any dehumidifier available, removing 480 liters of moisture per day at 30℃/80%RH.
Energy Efficient
Removes up to 4 liters per kilowatt hour, helping minimize operational costs.
Yield Enhancement
Setup is simple, and humidity is constantly controlled to help prevent crop disease and pests.
Flexible Installation
The pre-installed electrical plug is simple to remove for hard-wired applications. Plus, options for suspended, freestanding, or ducted installation.
Safety Checks
Terminals on the dehumidifier make it easy to install a float switch to protect against overflows.
Digital Interface
On-board monitoring enables precise settings and simple diagnostics.
Remote Control
The temperature and humidity sensor is available to measure relative humidity at canopy height for optimum control of your grow environment, and relays diagnostics from the dehumidifier.
Built to Last
Dependability is at the heart of what we do.
