MRR engineers and delivers complete odorization systems for natural gas utilities, propane and LNG facilities, and the full spectrum of RNG applications.
From permanent odorization buildings to large custom skids and complex specialized applications, every system is engineered around site conditions, applicable codes, maintainability, and long-term performance.
Consistent, measurable odorant injection across changing flow rates and operating conditions keeps gas reliably detectable throughout the system.
Equipment layouts engineered for access, containment, and routine maintenance protect personnel, reduce downtime, and support safe operation for the life of the system.
Flexible system architectures accommodate new gas sources, future capacity, and evolving operational needs without compromising reliability.

Every project begins with a clear picture of the operating requirements. Our engineers work with owners, operators, and consulting teams to evaluate flow conditions, odorant demand, site constraints, and applicable codes before defining the system scope.
MRR develops the complete design package: process configuration, equipment selection, station layout, controls integration, P&IDs, specifications, and installation requirements. Every design is engineered for the application rather than forced into a standard package.


MRR manages fabrication, quality control, installation, and startup as one coordinated scope. Formal QA/QC and factory acceptance testing confirm the completed system is fully documented, ready for service, and aligned with the approved design.
MRR develops specialized odorization solutions for unique operational requirements, including low-flow systems, odorant delivery trucks, custom injection equipment, and other engineered systems built to address site-specific challenges.
MRR provides engineering support and consulting services, including system design reviews, odorization performance assessments, and guidance for industrial, commercial, and institutional gas systems where odor fade risks may occur.
For larger installations, MRR designs permanent odorization facilities housed within dedicated buildings or station infrastructure, supporting long-term utility operations with safe access for maintenance, monitoring, and equipment servicing.
Designed and fabricated by MRR, odorization skid systems may incorporate specialized technologies such as bypass odorizers to improve operational flexibility, reduce refill frequency, and maintain consistent odorization performance over time.
Fully engineered, PE-stamped odorization packages: designed, fabricated, and installed by MRR, from CSA and CRN certified bypass odorizers to complete stations. Optional orbital welding reduces field joints and potential leak points.
