Rhino Controllers is the fan-control product line of Rhino Ventilation, a UK brand focused on horticultural grow‑room ventilation. Founded in 2005, Rhino expanded from carbon filters into fans and controllers in 2010 and, in 2024, launched a refreshed controller range. The lineup includes the Rhino EC Fan Controller (touchscreen, up to four fans), 1EC and 2EC controllers for single or dual EC fans, the 2EC+RH model with temperature and humidity control plus fan‑balancing for precise negative pressure, an EC Dimmer, and the AC RC‑1 controller. Designed to plug directly into Rhino Ultra EC fans, these units provide automatic or manual speed control to stabilize temperature and humidity in indoor gardens, including cannabis grows. Rhino products are distributed globally from Rotherham, England by Global Air Supplies.
