We’re introducing OUB, a new range of high-performance oil separators and receivers for CO₂ transcritical systems, helping OEMs and system designers protect compressors, maintain stable operation and improve efficiency.
Part of our CO₂ oil management ecosystem, OUB offers up to 140 bar operating pressure, advanced filtration and flexible options across serviceable and hermetic types, delivering a robust, high-pressure solution for demanding CO₂ environments.
Built for performance and serviceability
OUB is designed for CO₂ transcritical systems with:
- Up to 140 bar operating pressure
- Stable performance in high-pressure environments
- Long service life supported by advanced filter construction
- Straightforward installation and maintenance in serviceable models
"With OUB, we’re giving OEMs a technically advanced oil management solution that integrates seamlessly into high-pressure CO₂ systems. It’s engineered for reliability, serviceability and long-term performance in demanding applications."
Two construction types, three core variants
Our OUB range includes:
- OUB-TSR - Serviceable, with receiver
- OUB-TSN - Serviceable, without receiver
- OUB-THR - Hermetic, with receiver
Serviceable models feature:
-
Filtration capacity down to 0.3 microns
-
Three-stage coalescing filtration for progressive oil droplet growth
-
Advanced multi-layer filter design with stainless steel mesh, fibre fleece and perforated metal for strength and clog resistance
-
Over 3300 cm² filtration area in a V-shape design for extended service intervals
-
Technician-friendly design with clear access points, replaceable filter inserts and standardized connections
Hermetic models use demister technology for 3–10 micron filtration, offering maintenance-free operation and long service life.
“We’ve focused on proven engineering and practical usability. For technicians, that means clear access, efficient servicing and confidence in long-term operation.”
Part of our complete CO₂ system portfolio
OUB complements our CO₂ oil management ecosystem, including COM oil management controls, level sensors, filter driers and valves - reinforcing our role as a complete partner for high-pressure CO₂ systems.
