Custom-built gas upgrading modules for engineering-led projects
We manufacture tailor-engineered purification systems that integrate fast, scale easily, and meet demanding project specs, backed by 15+ years of proven field experience.
Gazpack for Engineering Firms
Gazpack is a manufacturer of modular gas upgrading systems built to fit seamlessly into complex energy, waste, and industrial projects. For over 15 years, we’ve helped engineering firms deliver reliable, scalable gas treatment solutions for biogas, oil & gas, landfill, and industrial effluent applications.
We don’t just design systems – we build them. Our Sulago platform and supporting modules (desulfurization, CO₂ separation, odorizing, and more) are developed in-house, with proven performance across international projects. Each installation is tailored to your spec and delivered with full documentation and integration support.
We understand the pressure engineering teams face: balancing tight timelines, evolving environmental requirements, and client demands for high-purity gas recovery or CO₂ reuse. Off-the-shelf systems rarely align. That’s why our modular approach is built around flexibility and project reality – not just theory.
We support you from feasibility to commissioning, working as a trusted partner to deliver complete, field-tested solutions. Our technology is ready to be built into your designs and scaled across markets – with the added value of supporting certification where needed.

We help you succeed across all major segments
01
Biogas Operators
Stabilize output and meet RNG standards. We deliver modular systems that solve biogas inconsistencies, remove H₂S and CO₂, and ensure compliance for grid injection or fertilizer-grade reuse.
02
Renewable Gas Plants
Enable scale-up and meet global specs. Our purification units support RNG and LNG production with lower OPEX, modular scaling, and readiness for diverse regional regulations.
03
Landfill Sector
Turn landfill gas into a valuable stream. We help recover energy from CH₄-rich gas, eliminate sulfur and odor, and deliver a cleaner alternative to flaring or low-efficiency systems.
04
Water Treatment & Filtration
Recover energy from complex effluents. We integrate with wastewater and anaerobic digestion processes to reuse CH₄ and H₂S, cut treatment costs, and meet stricter air/water emission rules.
Our products
Sulago
Small-scale biogas upgrading made modular and affordable
Sulago is Gazpack’s compact solution for facilities with gas flows up to 1,500 Nm³/h. Designed for scalability, low OPEX, and simple deployment, this plug-and-play unit combines high H₂S and CO₂ removal efficiency with a small footprint — ideal for farms, wastewater facilities, or pilot projects needing certified-ready purification.
Sulaway
High-capacity upgrading system for industrial-scale gas purification
Sulaway is built for large-scale operations handling over 1,500 Nm³/h of raw biogas. Tailored to meet grid injection and liquefaction requirements, it provides high-purity output with robust desulfurization, CO₂ recovery, and minimal methane slip. Fully manufactured and assembled by Gazpack, the Sulaway is a proven choice for upgrading at scale.
