FAQ
if the fans doesn't work well, what shall I do ?
If happens within one year, we will take in charge of the
maintenance, or send you a new machine freely.
If after one year, we will supply you the right parts to replace at
low price.
What about delivery date?
Product can be sent to you within a week if there is stock after
receiving deposit or 100% payment from customer. If there is no
stock, the delivery date will be 15 to 30 days.
Air performance curves
Our performance curves are tested in test camber according to DIN
24163 and refer to an air density of 1.2kg/M3. Testing conducted
with inlet cone in airflow direction A, without protection guard
How does this affect energy efficiency?
1. Doubling the speed of a motor increases its power input by a
factor of 8 so it’s very wasteful to run a fan faster than is
required. If you can tailor the fan speed to match the demand, the
potential for energy saving is huge. Even when compared to on/off
operation, EC speed modulation is much more efficient.
2. EC fans can also contribute to increasing the overall efficiency
of an application. In a cooling system for example, keeping the
refrigerant pressure constant rather than having it rise and fall
as fans switch on and off has been found to reduce the load on the
compressor resulting in even greater energy saving.
3. If two motors are producing the same output but one has a
greater power input then you can be sure that the surplus energy is
being dissipated as heat. If an application is designed to remove
heat then it will have to do extra work just to remove the heat
produced by the fan motor itself, so EC fans will improve the
efficiency of the whole system.
EC Motor – Principle
With an EC motor the electronic circuitry stands in lieu of the
traditional mechanical commutation meaning the right amount is
being supplied in the right direction at exactly the right time
providing precise motor control.
Permanent-magnet brushless DC motor within the rotor
The stator is driven by electronic switches (which replace the
Carbon brushes), controlled by a microcontroller.
Electronic system (hall effect sensor or software is used to
recognize the rotor position)
AC operated (230Volts Single phase or 380/480Volts 3phase, 50/60Hz)
