Type D CNG Compressors

General Description Available with capacity between 700 and 4500Nm3/h, the type D CNG compressor is ideal for medium and large sized CNG filling stations as well as CNG mother stations. As a kind of horizontally symmetrical reciprocating compressor,it is mainly composed of the compression unit, anti-explosive electric motor, cooling unit, lubrication unit, internal connection pipeline, safety valve, and the blow-down valve. All these components are skid-mounted on a common base, thus facilitating installation and transportation. The PLC control cabinet is usually positioned inside the control room of CNG filling stations so as to realize remote control on the CNG compressor.

Features:

Our compressors feature large capacity, low vibration, high efficiency, aesthetical design, and compact structure. Also, they support long term continuous operation due to reliable and stable performance. User-friendly designed, they are convenient for maintenance, and require low operation cost. Their parts are available at very competitive prices. The PLC control system ensures higher safety and stability.

Advantages

1. We have been in compressor manufacturing industry for over four decades, and up to now, we have supplied over 2500 sets of compressors for national and international 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. UAccording to clients' specific requirement, 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.
