Daughter Station CNG Compressors

General Description

Daughter Stations are installed where a CNG fill station is desired but there is no natural gas pipeline. Natural gas is brought to the CNG station by mobile storage.  A daughter station compressor quickly and efficiently moves the natural gas from the mobile storage to a ground storage.  The daughter station compressor can also be used to directly fill vehicles.


1.On the basis of our four decades experience in compressor manufacturing industry, we have produced and supplied over 2500 sets of CNG compressors for domestic and overseas clients.  We have won 40% of the market share in China. 
2. Due to our powerful development capacity as well as our close cooperation with China famous universities such as Xi'an Jiaotong University, Sichuan University, Sichuan University of Science and Engineering, etc., we have achieved a leading position in compressor manufacturing technologies. In the filed for CNG filling stations, we were the earliest Chinese developer of horizontally symmetrical type D CNG compressor for mother stations and type XD CNG compressor for daughter stations. 
3. We operate in strict conformation with TQM (Total Quality Management), TPM (Total Productive Management), and TPS (Toyota Production System) management systems which are widely used by American, Japanese and Korean enterprises. 
4. Before leaving factory, all of our compressor has to undergo heavy load tests to avoid any possible failures. This is one of the reasons why our range of compression equipment has reliable performance. 
5. Our gas compressors are available with performance test reports provided by a third party, as well as pre-delivery tests such as SGS and OMIC. According to clients' specific requirements, we can also provide ABS and CCS certifications. 
6. Our compressor systems are equipped with key components of international or domestic famous brands to offer enhanced reliability. By now, we have established cooperation with ParKer (American), HOERBIGER (German), DK-LOK (South Korean), mercer (American), STAUFF (German), Siemens (German), Jiamusi Electric Machine Company Limited, Wuxi Xi Shan Anda Explosion-proof Electrical Equipment Co., Ltd., Nanyang Explosion Protection Group Co., Ltd., Xi Chi Electric Co., Ltd., and Sichuan Injet Electric Co., Ltd. The partnership with national and international industry leaders provides us great advantages in market competition. 
7. We have a complete after sales network in mainland China, covering all provinces and areas. Also, we have built after sales centers in countries such as Thailand, Pakistan, Uzbekistanbekistan and so on. Chinese or local personnel are available for equipment maintenance and repairing. Technical supports and assistance in Chinese, English, Russia, etc. are available. Free maintenance and operation trainings are provided as well.
