Features and Benefits
Design
The compact and low profile GL Gamma EC Series is a simple “plug and play” system which means installers do not need to have specialised control programing knowledge. They are suited to ducted vertical exhaust applications, include a removable windband that provides easy access for cleaning and maintenance.
Sensors
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.
Protection
Integral thermal overload protection is supplied as standard.
Testing
All units are tested to ISO 5801:2007 (airside performance) and ISO 3744:2010 (sound performance).
Specification

Motor
The fans are built with electronic commutated (EC) motors with sealed for life ball bearings. The motor requires an electricity supply of 200-277V single-phase, 50/60Hz for 315 to 450mm sizes. Electricity supply of 380-480V three-phase, 50/60Hz is required for 560 and 630mm sizes. Maximum ambient temperature is 60°C CDEC56VGL cannot exceed 16.8r/s at 60°C
