Vortair EC Series – CUEEC50
Performance Curve - CUEEC50
Description
The Vortair® EC Series of In-Line Mixed-Flow fans 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 fully integrated, infinitely variable speed control which eliminates the need for external VSDs, current overloads and motor phase protection.
Optional matching sensors monitor the ambient conditions
and provide real time feedback to the fan. The fan's on-board
microprocessor adjusts the speed and therefore modulates the
ventilation rate to match the specific requirements of the area.
The Vortair® EC fans are a simple "plug and play" system which
means installers do not need to have specialised control
programming knowledge.
Vortair EC Series feature a heavy duty galvanised steel circular
fan casing that can be retrofitted into axial fan installations that
may require greater static pressure. They are available in 5 case
sizes ranging from 450 to 710mm diameter (280 to 450mm
impeller diameters).
Features
- Innovative mixed-flow impellers produce powerful airflows without generating high noise levels.
- EC motor features reverse polarity protection, locked rotor protection and soft starting.
- No additional electrical protection such as contactors are required.
- All models supplied standard with 0-10V control input. Diameter sizes from 400mm 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.
- Heavy duty galvanised steel construction.
- Can be retrofitted into standard 450 to 710mm axial fan installations.
- Mixed-Flow impellers suit applications where medium to high air pressure is required.
- Can be mounted in any position.
Construction
Mixed-Flow impellers are made from high performance injection
moulded composite material. Casing made from heavy duty
galvanised steel.
Motors
Type - electronic commutated (EC) motor.
Electricity supply - 200-277V single-phase, 50/60Hz
Bearings - sealed-for-life, ball.
Integrated EC-Controller providing infinite speed control.
Internal Thermal Protection
Integral thermal overload protection is supplied as standard.
Testing
Air flow tests based on ISO5801: 2007
Noise tests based on ISO13347: Part 3, 2004
Special Note
Diameter sizes 630 and 710mm can be pre-configured to suit
specific sensors and specific applications. Please advise
Fantech 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.
