Overview

The GL Gamma EC Series of centrifugal roof mounted exhaust fans incorporate 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 units are available in 315, 355, 450, 560 and 630mm fan sizes.

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

Construction

The cowl is a vertical discharge design and manufactured from galvanised steel. Steel components shall be corrosion protected. The windband incorporates a quick-release toggle clamps to provide easy access for cleaning and maintenance.

Impellers

Impellers shall be made from high performance composite material. Backward-curved centrifugal design.

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

Control

Integrated EC-Controller providing infinite speed control.

Additional Information

Backdraft shutters are an optional extra. The pressure loss across the shutter has to be added to the system pressure before making selections. All GL Gamma EC models can be pre-configured to suit specific sensors and specific applications. Please advise Elta Fans of these parameters at the time of order. EC motors should be directly connected to their appropriate AC supply. EC motors should not be regularly power cycled.
