Gamma EC Vertical – CEEC25V
Performance Curve - CEEC25V
Description
The Gamma EC Series of centrifugal roof mounted exhaust fans incorporates the latest state of the art, energy saving EC motor technology. They feature integrated infinitely variable speed control and eliminate the need for external VSDs, current overloads and motor phase protection.
The Gamma EC Series is a simple "plug and play" system which means installers do not need to have specialised control programing knowledge.
Matching sensors can easily be connected to monitor the ambient conditions in a space and provide real time feedback to the fan. The fan's on-board microprocessor can adjust the speed and therefore modulate the ventilation rate to match the specific requirements of the area.
Models come in downflow or vertical discharge configurations and are available in 250, 315, 355, 450, 560 and 630mm fan sizes.
Features EC motor features reverse polarity protection, locked rotor protection and soft start.
No additional protection such as contactors are required.
All models supplied standard with 0-10V control input.
Diameter sizes 315mm and above can be pre-configured to suit specific sensors and specific applications.
A full range of sensors are available including differential pressure, humidity, temperature, air velocity and pollutant.
Can be run as an independent ventilation source or integrated into most building management systems.
Robust and lightweight construction.
Compact, low profile design.
Designed for vertical exhaust applications.
Can be mounted at angles up to 30°.
Supply air units are available
