IMW’s Bulk Gas Transportation systems have enabled customers worldwide to take advantage

of the tremendous cost reduction and environmental benefits of converting to natural gas without

waiting for expensive pipeline of LNG infrastructure. IMW’s Pressure Reducing System (PRS) is

designed for pressure let-down of CNG delivered via CNG trailer at pressures up to 3600 psig.

The PRS is comprised of two main components, the Pressure Reducing Module (PRM) and the

Heat Control Module (HCM). These systems are skid-mounted and have different electrical zone

characteristics. The PRM creates a Class I Zone 2 area for 15 feet* in all directions from the edges

of the skid.*Based on the applicable NFPA52 code used in the USA

IMW’s Mobile PRMS includes proven CNG systems in the ease of a mobility package. Each pack-age has an industrial CNG compressor, high-pressure CNG storage, multi-point CNG dispensing, gas controls and electrical controls, all on a unique, purpose-built transport trailer.

In conjunction with IMW’s compressors, our Pressure Reduction Systems allow

Maximum Offload Capacity, ensuring that only a minimal amount of gas is left on the trailer before it is

disconnected. This is achieved by using two line unloading methodologies where possible, designing

systems for minimal pressure drop, and employing scavenging compression where necessary to remove

remaining gas.

Along with IMW’s compressors, our Pressure Reduction systems have proven

scalability to provide standard product to custom applications. This provides redundancy. Standard prod-

ucts ensure excellent reliability and quality. It is easy to add more units if demand increases and remove

equipment and move to several smaller sites once gas pipeline arrives.

Technical

Features- System mobility

- Self-contained fueling system

- Trailer decant hose is the interface between CNG trail-ers and the PRS

- User friendly touch-screen HMI for set-point and alarm control

- Boiler utilizes natural gas from the tube trailer

- Emergency Shutdown System (ESD)

- Uses 2-stage regulation for maximum consistency of outlet pressure

- Oversized components to retrieve maximum capacity from mobile storage units by allowing mobile storage to drain to lower pressure levels while maintaining rated flow through the PRS

Benefits- Reduces capital costs in site construction

- Easily accessible controls for rapid fine tuning of performance

- System designed for fast response to fluctuating site conditions

- Deployment/re-deployment made simple by the use of 1 ton trucks

APPLICATIONS

Permanent Site Deployable Site Mobile SiteIndustrial application where natural gas pipeline infrastructure is not available, yet significant cost savings can be realized by utilizing natural gas as the energy source instead of conventional fuels such as bunker oil. IMW’s compression and decompression equipment can be used together with mobile storage to create a virtual pipeline in order to recognize these cost savings.

Multiple modular PRS units that are easy and cost-effective to transport can be installed in par-allel at temporary sites in order to allow rated capacities in multiples of IMW standard equipment rated flowrates. Individual units can be re-deployed to other sites with different capacity requirements once the need at the original site changes.

The IMWDifference

IMW non-lubricated compressors set the global standard for minimum oil carry-over without the waste, cost and negative environmental issues of additional filters, auto oil drain systems and supplementary oil tanks. Only 5 PPM or less vs. 100 PPM or more.

IMW is the largest and only exclusive manufacturer of non-lubricated CNG compressors globally making us a proven manufacturer with the world class experience you need supporting you.

IMW has the best durability and reliability in the industry.

IMW is the only manufacturer offering advantages of twin & triple configura-tions. This allows for variable supply for higher efficiency at low demand periods and full redundancy and enhanced reliability.

IMW is the only manufacturer that covers the widest spectrum of compression requirements with a single block instead of multiple, unique machines. Less training is required and there are more common parts.
