About product

Main features

High safety class
ECM motors adopt thermoplastic for housing and the protection level has achieved class II, therefore the earth conductor will be unnecessary and the cost will be reduced.
High protection class IP65

Enclosed motor design will have a better moisture-proof effect and make It possible to work in the high humidity and dust environment

High reliability

The dual-chamber design(Patented) leads the motor can be effectively separated from electronic control area in order to avoid dust and humidity enter in to the cavity of control board.Regarding oomponencs selection. We cooperale with the world' s leading suppliers in order to offer the best quality.Our R&D department has done various of tests to simulate the real working conditions of the fans (such as temperalure, vibration, lifetime, etc.) in order to make the design more reliable.All of our products are designed with high quality and long lifetime We work over everypart of our ECM motor, carefully cloose devices and materials, together with suitablecontrol board and intelligent protection system, our motors had achieved a life expectancy over50,000 hours in continuous working conditions.

Constant speed control

constant speed control means the motor mintains a constant speed across a wide range of vollages and fan blades, it will help the coolng system work properly and avoid the noise generated by the fluctuation of motor speed

Reverse on start

ECM motors an run backwards automatically when start-up through pre-set of the programme This important functlon can help to blow away dust from the heat exchanger of the condenser in order to make the refrigeration system more efficient. Further more, there is no extra signal control needed to achieve this function.

Reverse on demand

With this feature you can determine the time and duration of reverse running. For example, during the compressor "off" period or Ihe defrost cycle, you can start reverse running to blow away dust.Moreover, without needs of extra relays can save more cost.

Two speeds

ECM motom can run both in high-speed and low-speed through pre-set programme by Supplier, this ruction would be very useful in the relrigeration system application which has daytime and nighttime modes. thus to save more energy and reduce the noise.

O-lOVdc Full speed control

ECM 0-10V step-lass speed regulation motors include AC and 24VdC power supply.operators can control the O-10Vdc to control the signal light to process step-less speed regulation It will intelligently control the cont rol system and result in better energy saving effect.
