APPLICATION

Cold-chain transportation

Refrigeration compressors are used in logistics centers for  refrigerated vehicles and cold storage facilities. They are used  to maintain the appropriate temperature of goods during  transportation, ensuring the quality and safety of the goods.

commercial refrigeration

Refrigeration compressors are used in supermarkets and  convenience stores for refrigeration and freezing equipment,  such as refrigerators, freezers, and refrigerated shelves, etc.  They can maintain the appropriate temperature for food and  beverages, ensuring the freshness and quality of the products.

Medical refrigeration

In pharmaceutical refrigeration, the compressor is the core  component of pharmaceutical refrigeration equipment, mainlThe performance test station has also been calibrated by a  nationally recognized metrology testing center to verify the  rationality of the design, manufacturing, and assembly of  the refrigeration compressors, ensuring that the performance index of the refrigeration compressors meets the  industry's advanced standards!y  used to provide refrigeration effect, ensure the storage and  transportation of drugs within the appropriate temperature  range, thereby ensuring the quality and effectiveness of drugs.

industrial refrigeration

Refrigeration compressors play an important role in industrial fields such  as high & low temperature alternating test chambers. They are usually  used to simulate different environmental temperature conditions for  testing and evaluating products in industries such as electronics,  automotive, aerospace, etc., providing stable and reliable refrigeration  effects to ensure the performance and reliability of products under  different temperature conditions.

R & D STRENGTH

Briliant's professional production and processing technology and  outstanding design quality are the cornerstones and premise of  Briliant's refrigeration industry. Briliant adheres to the scientific  testing method, which is the best quality assurance and commitment of Briliantto customers. Briliant will open the first brand of  refrigeration compressors, so that customers can truly understand  the true meaning of quality.“GB/T10079-2018Single-stage reciprocating refrigerant  compressor (unit)” new national standard for the first time put  forward the concept of "accelerated life", mainly for the domestic  industry generally on the compressor body, crankshaft and other  materials on the application of low standards, strict requirements,  appeared It can be used at the beginning, and after a period of  time, the quality of the life cycle is generally severely declining. The  new national standard stipulates that the range of noise and  cooling capacity in the life cycle of the compressor does not  exceed 3dB(A) and 5% of the new machine respectively.

TESTING CENTER

Briliant insists on scientific and professional testing  methods constantly. The company has built three refrigeration compressor performance testing stations and an  online testing assembly line. The refrigeration compressor  performance testing stations covering semi-hermetic  refrigeration piston compressors and semi-hermetic refrigeration screw compressors. Our online testing process  covers key parameters such as airtightness testing, forward  and reverse voltage, current, oil pressure, and volume flow  rate for each refrigeration compressor. We also monitor  and record the performance of refrigeration compressors  under different operating conditions in real-time. By  obtaining real-time data five times and generating an  average value, we can more accurately evaluate the  conventional performance indicators of refrigeration  compressors, ensuring that each refrigeration compressor  leaves the factory without any quality defects.The refrigeration compressor performance testing stations  differ from the online testing assembly line in that the  former adopts imported high-precision measuring instruments. The performance testing stations are built based on  the “GB/T5773-2004The method of performance test for  positive displacement refrigerant compressors” and the  refrigeration compressor performance testing is conducted  based on the " GB/T 10079-2018 Single-stage reciprocating  refrigerant compressor(unit) "and" GB/T19410-2018  Screw refrigeration compressor".
