Short Case EC – SCEEC35
Performance Curve - SCEEC35
Description
The Short Case Axial EC Series fans incorporate the latest
state-of-the-art EC motor technology. The range features fully
integrated, infinitely variable speed control which eliminates
the need for external VSDs, current overloads and motor
phase protection. They are an energy saving solution
and are most efficient where conditions vary during the course of the day.
Optional matching sensors monitor the ambient conditions in a space and provide real time feedback to the fan. The fan's
on-board microprocessor adjusts the motor speed and therefore
modulates the ventilation rate to match the specific requirements of the area.
The Short Case Axial EC fans are a simple "plug and play"
system which means installers do not need to have specialised control programing knowledge. They are available in 7 sizes ranging from 250 to 630mm diameter.
Features
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 500mm and above can be pre-configured to suit specific sensors and specific applications.
A full range of sensors are available including differential pressure, temperature, air velocity and pollutant.
Can be run as an independent ventilation source or integrated into most building management systems.
Compact, short case design with light-weight but robust construction.
Low noise, high performance impellers with enhanced aerodynamic design.
An electric junction box is fitted as standard.
Capable of operating at temperatures up to 60 °C.
Units can be mounted at any angle.Construction
The casing is of galvanised steel with a polyester epoxy finish as standard.
Impellers are of high performance composite material.
Motors
Type - electronic commutated (EC) motor.
Electricity supply - 200-277V single-phase, 50/60Hz or 380-480V three-phase, 50/60Hz
Bearings - sealed-for-life, ball.
Integrated EC-Controller providing infinite speed control.
Internal Thermal Protection
Automatic reset protection is supplied as standard.
Testing
Air flow tests to BS848:Part 1, 1980
Noise tests to BS848, Part 2, 1985
Special Note
Diameter sizes from 500mm and above 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.
Suggested Specification
