Rhino 2EC Fan Controller – Dual Fan Thermostatic Controller with Negative Pressure Management

The Rhino 2EC Fan Controller provides advanced thermostatic control over both intake and outtake EC fans simultaneously, giving growers precise management of the grow room environment. Like the Rhino 1EC, it features analogue dials for setting minimum and maximum fan speeds and target temperature — but the 2EC goes further with an additional offset dial specifically for managing negative pressure.

Negative pressure is created when more air is exhausted from the grow environment than is being supplied. Maintaining the correct balance is essential to prevent “ballooning” or structural stress on the grow space. The offset dial ensures both fans run in tandem to maintain the correct differential, keeping the environment stable and properly ventilated.

The controller runs directly off the power supplied by the connected fans, eliminating the need for an external power supply. Compatible with the full range of Rhino EC Ultra fans.
