Gamma Ultra EC Supply Series - Variable Speed Fans
Description
The Gamma Supply Ultra EC Series of mixed-flow roof units can
be used for supplying fresh air to an air handling unit or to an air
conditioning system. They incorporate the latest state of the art,
energy saving EC motor technology and are most efficient where
conditions vary during the course of the day.
They feature integrated infinitely variable speed control and
eliminate the need for external VSDs, current overloads and
motor phase protection.
The Gamma Supply Ultra 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.
They are available in 3 sizes extending from 450 to 560mm
diameter.
Typical Application
Supplying fresh air to an air handling unit or to an air
conditioning system in commercial buildings. Also suitable
where make-up air or positive pressure is required in the
ventilated space.
Features- Robust, lightweight construction.
- EC motor features reverse polarity protection, locked rotor
- protection and soft start.
- No additional protection such as contactors are required.
- All motor sizes can be pre-configured to suit specific sensors and specific applications, and are supplied standard with 0-10V control input.
- 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.
- High performance mixed-flow impellers fitted.
- Can be mounted at angles up to 30°
