Description
Rhino 2EC + RH Fan Controller
The Rhino 2EC + RH Fan Controller is a high-precision digital climate controller built for growers who want stable, automated control of temperature, humidity, and airflow. Designed to work with EC extraction and intake fans, this controller constantly monitors your environment and adjusts fan speeds in real time to keep conditions exactly where you set them, even when the space is left unattended.
Once calibrated, the controller automatically responds to changes in heat or moisture by increasing or reducing each fan’s speed independently. This maintains a balanced grow environment, protects plant health from stress, and ensures consistent performance across the day and night cycle. Separate day and night settings allow you to run distinct climate targets without manual switching, reducing shock during lights-off transitions.
A key advantage of the Rhino 2EC + RH system is its built-in fan balancer, which maintains stable negative pressure. This prevents tent ballooning or collapse, especially in lightweight grow tents. The controller only activates the intake fan when required, balancing pressure within around 1% of fan speed. This intelligent operation lowers energy use, reduces wear on your fans, and keeps the entire system running efficiently.
Compatible with Rhino EC Ultra fans and suitable for grow spaces of any size, the Rhino 2EC + RH Fan Controller is a reliable upgrade for growers aiming for professional-grade climate stability.
