CRA is an authorized packager and distributor for Ro-Flo Compressors. The authorization reflects a relationship built on delivered projects.

‍

The partnership exists because proven compression technology requires an engineering team that knows how to put it to work.

‍

The Partnership

‍

Ro-Flo Compressors manufactures rotary sliding vane compressors and all associated OEM parts, with applications across biogas, vapor recovery, landfill gas, and wastewater treatment. The sliding vane design delivers continuous compression with no valves, handles gas gently, and suits the saturation and variability that biogas streams bring.

‍

As an authorized packager and distributor, CRA engineers the complete system around the Ro-Flo compression unit. That scope covers inlet filtration, dehumidification, gas train design, skid fabrication, controls integration, and commissioning, all built in house. CRA holds a direct technical relationship with Ro-Flo's engineering department, and Ro-Flo provides full technical support throughout project execution. OEM parts are used exclusively for all supply and aftermarket servicing.

‍

Ro-Flo engineers the compression. CRA engineers everything around it.

‍

Proven in the Field

‍

Two projects demonstrate what this combination delivers.

‍

For Mazoon Dairy in Oman, CRA engineered a 443 Nm³/hr compression skid to transport biogas across a pipeline spanning 4 kilometres at 2.5 bar, operating continuously in desert heat with a duty and standby Ro-Flo configuration. The system has run without interruption since commissioning. Read the case study →

‍

For Adani Infra's anaerobic digester facility in India, the requirement was more complex: biogas recirculated sequentially through multiple lances across three RCC digesters, with a dedicated Ro-Flo unit and standby per channel, controlled by a modulating rotary sequential valve system. The project delivered a 15% increase in biogas yield and 54% cost savings against the alternative. Read the case study →

‍

Both systems are successfully commissioned and in operation today.

What This Means for Your Project

‍

Most biogas compression projects involve at least two parties: the compressor supplier and the system integrator. When those are separate, the risk sits in the gap between them. Inlet gas specifications that don't match the compressor's actual requirements, preconditioning that is adequate in isolation but not designed to the machine's inlet needs, controls that treat the upstream system and the compression unit as separate equipment rather than one process. That gap is where most field problems originate.

‍

As an authorized packager, CRA closes that gap. The technology selection, the preconditioning design, and the controls architecture are engineered together, by one team, to one set of process conditions. There is no split between a compressor supplier and a balance of plant contractor. The accountability for the outcome sits in one place.

‍

For the customer, the authorized packager relationship delivers three things.

‍

Full system integration from inlet gas to discharge, with the compressor and all surrounding engineering under one scope and one accountable party. No split responsibility between a compression supplier and a balance of plant contractor.

‍

Genuine OEM parts and direct Ro-Flo technical support throughout the project lifecycle, so there is no gap between the equipment manufacturer and the system integrator during design review, commissioning, or long term servicing.

‍

A formalized supply chain, not an improvised one. Authorized distribution means lead times and parts availability are managed as part of the project from the start, not treated as procurement risk during execution.

‍

What's Next

‍

Biogas compression requirements are growing, across India's CBG programme, across wastewater and landfill gas projects regionally, and in markets where biogas to energy infrastructure is scaling at commercial pace. Each of those projects requires a compression system that performs to specification reliably, across variable feedstock, seasonal gas compositions, and load cycles.

‍

CRA is positioned to deliver that system, with Ro-Flo compression engineered at its core, and one point of accountability for the outcome.
