1. 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.
Can be pre-configured to suit specific sensors and 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.
The applicable ambient temperature of the fan motors used in condenser is from -30~60
The average service life of motors is over 30000 hours
Our products have got CCC certificate and CE certificate
Can we buy a sample for testing?
Sure, you are welcomed to buy a sample before mass order.
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.
