Zhejiang Maidi Refrigeration Technology Co., Ltd. is a Hi-tech enterprise, founded in 2009. We specialized in manufacturing and exporting the household refrigerator compressors, commercial refrigeration compressor & unit, which used in R134A, R600A, R404A, R290 systems, the voltage range from 220V-240V, 110V, 12-24V. Also we manufacture a variety of liquid line refrigeration spare parts such as filter drier, liquid accumulator, Liquid Receiver, oil separator, vibration absorber and condensate pump.
We are located in Hangzhou city, who has the reputation of China Heaven. It will take one hours to Shanghai or Ningbo port by train, and 45 minutes to Hangzhou Xiaoshan International Airport by car.
We own the standard plant and office building which covering 21, 000 square meters. With abundant technique force, we have our own researching, developing, manufacturing, inspecting and testing centers, and imported the international advanced equipments. Our whole factory is managed according to I S O 9 0 0 1, I S O 1 4 0 0 1 international management systems. The products are certified by CCC, CE, UL, ETL and CB. Our products are not only selling strongly in more than 30 provinces and municipality, but also largely exporting to Europe, America, Australia, Middle East, Africa and South Asia. We have won an excellent reputation from the customers and friends by our product quality, price versus performance ratio and service.

Quality
1 ,Characteristic
Characteristic is measured by rated voltage, rated frequency, the value of the characteristic must be in standard value in the characteristic table.
2 ,Insulation
a . Insulated resistance
The insulated resistance must be more than 200MQ at the time of normal temperature and humidity.
b . Electric strength
The motor is under 1500VAC for one minute or 1800VAC for one second.
c . Damp proof
The insulated resistance must be 100MQ or more when the test piece is exposed to the temperature of 40±3C and humidity of 90% for 48 hours.
3 ,Life
When driving at the normal rated ,normal load conditions, continuation drive is possible, the operation time is 60000 hours or more.
4 ,Supply voltage
When the supply voltage changes at the rate of±10%, the motor keeps operating normally.
5 ,The lead wire tension strength
When the lead wire is pulled at the force of 5.0N per one wire for 3 second, it must that no failure occurs on the connection.
6 ,Temperature condition
The temperature for use:-40ºC~60ºC .
7 ,Relative humidity
The relative humidity in the dampest month is 90% (The lowest temperature every month is 25ºC or less.)
8, Noise
When the motor is operating under no load, the noise is less than 45db(A)
Measuring Manner: Taking the corresponding motor to the Un-echoic Room,
obtains internal environment noise is 10dB first, again uses a decibel reflectoscope
reflector to survey the motor's sound, demonstrated the data subtracts the
environment noise, is the motor's noise.
Welcome to visit us through exhibitions. We take part in many exhibitions every year.
