Performance Curve - CPEEC31DD

Description

The ECOtronic EC Series of square plate axial fans incorporates an IE5* rated Electronically Commutated (EC) shaft motor delivering ultra energy efficient operation with the benefit of in-built variable speed control. Via a range of common control signals, the ECOtronic can be easily designed into a Demand Control Ventilation system without the need for a VSD and motor overload protection. The ECOtronic EC fans are a simple “plug and play” system which means installers do not need to have specialised control programming knowledge. The series is available in 8 sizes ranging from 250 to 630mm diameter.

Features

Ultra energy efficient by combining aerofoil “Series 1” impeller blades and IE5* rated EC motor
EC motor features reverse polarity protection, locked rotor protection and soft start
No additional protection such as motor overload protection is required
Can be manually speed controlled by pressing 2 internal motor buttons
Can be remote speed controlled with either a 2-10V, 4-20mA,or 80-1600Hz input signal
Can be run as an independent ventilation source or integrated into most building management systems
Maximum operating speed can be adjusted from 1800rpm to 200rpm
On board fault identification LED will flash according to fault type
Integrated “Fire Mode” function forces motor to continue working under adverse conditions (at set speed)
Guard is incorporated as standard.
Units are light weight and can be mounted at any angle.
Robust galvanised steel construction with polyester epoxy finish.
Operating temperature: -20 oC to +60 oC when air velocity exceeds 5 m/s, otherwise -20 oC to +40 oC

Construction
The ECOtronic square plate manufactured from durable galvanized steel with a high quality polyester epoxy finish. Impellers are of high performance composite material.

Motors
Type - electronic commutated (EC) motor.
Electricity supply - 220-277V single-phase, 50/60Hz.
Bearings - sealed-for-life, ball.
IP55 rating.

Internal Thermal Protection
Integral thermal overload protection is supplied as standard.

Testing
Air flow tests to ISO5801: 2007
Noise tests to BS848:Part 2, 1985

Special Features

EC motors should be directly connected to their appropriate AC supply. EC motors should not be regularly power cycled.

Reverse flow: Derate the air flow by at least 25% if the air flow direction is reversed from standard. Add the suffix “R” to fan code.

* The IE5 Efficiency level is not currently defined by the IEC Standard, however the intent is for IE5 motors to have approximately a 20% reduction in losses against IE4 motors.

Suggested Specification

The square plate wall mounted axial fans shall be of the ECOtronic EC Series as designed and manufactured by Fantech Pty Ltd and be of the model numbers shown on the schedule/ drawings.

The axial impellers shall be made from high performance composite material. They shall be driven by an EC shaft motor with integrated speed controller and motor overload protection. Square plates shall be galvanised steel with a polyester epoxy finish.

All models shall be fully tested to ISO5801:2007 for air flow and to BS848:Part 2, 1985 for noise.
