Custom packages

Roots Systems excels in the design and assembly of custom packages for challenging environments. Our packages are designed with the protection of your process, personnel and equipment in mind. We can supply you with all the necessary safety features and instrumentation for monitoring, control, alarm and shut down.

We supply compressor packages both inside and outside of Europe that comply with local legislation and the standards used both onshore and offshore in the chemical and petrochemical, energy/power generation and oil and gas industries. Packages conforming to the latest edition of API Standard 619 are available.

Our custom packages are designed and engineered using the latest CAD technology reducing time and cost.

We offer:

We fabricate our own silencers in house and our own acoustic enclosures, complete with doors, forced ventilation systems, lighting, fire and gas detectors, and oxygen-depletion sensors.
