safe - CNG TECHNOLOGY is a result of years of experience with state-of-the-art technology and on-going Research and Development (R&D). Today, safe CNG Compressors are called the “Work-Horse” for CNG service for their efficiency and ability to run longer hours with minimum maintenance costs.

Complete safe systems are engineered, manufactured, packaged and tested in-house using our advanced standards and custom designs. These products conform to the stringiest quality standards and thoroughly inspected by third-party inspectors prior to delivery. 

A BROAD RANGE OF SOLUTIONS TO VARIOUS PROBLEMS

Multiple configurations are available to suit various site conditions including low inlet pressures with high capacity requirements, hydraulic compressors for daughter stations and small compressors for private fleets. Components are interchangeable between compressor models wherever possible, maximizing availability of parts.

 

Single compressors with flow rates from 15 ~ 6000 stm3/hr are vastly developed. Our multiple compressor systems offer higher overall flow rates plus equipment redundancy. Compressor systems are available with electric or gas engine drives to address the varying power requirements.

EXCLUSIVELY DESIGNED AND MANUFACTURED FOR CNG INDUSTRY

Many compressors currently operating as CNG compressors were originally designed for air compression, and simply modified for use with CNG. safe compressors were originally designed especially for use with CNG, and address the special requirements of clean fuel technology. Our compressors' record of dependability testifies to their superior design.

SUPERIOR DESIGN COMPARED TO OTHER BRANDS

The non-lubricated crosshead cylinder design of the compressor results in the lowest levels of oil carry-over (5 ppm or less) or contaminants to the vehicle. This design produces the cleanest possible downstream gas to avoid oil build-up in storage cylinders as well as ensuring cleaner combustion. Lubricated compressors require complex filtration systems to remove harmful oil carryover and tend to increase maintenance costs for CNG powered vehicles.

safe compressors offer a better alternative by using state-of-the-art Teflon® rod packing and piston rings that require no lubrication yet offer long service life.

Configured for Efficiency and Longer Life

safe compressors use single- and double-acting piston configurations for optimum efficiency and long life. These reciprocating compressors are designed to achieve excellent flow capacities while operating at slower speeds, dramatically increasing the life of piston components while substantially reducing noise and vibration.

 

Reliability testing has shown piston ring, packing ring and valve life in safe compressors to be substantially greater than other non-lubricated compressor designs. On safe compressors, the operational life of these consumable components is typically 4,000 to 10,000 hours.
