- Model VRUs - Guardian and Sentry Series of Vapor Recovery Unit



AEREON’s GUARDIAN and SENTRY series of vapor recovery units (VRUs) provide a reliable, low maintenance solution for condensate and crude storage vapor recovery in the upstream and midstream markets.

The AEREON GUARDIAN and GUARDIAN HP Series, our top end VRU, is available in both pre-engineered standard designs as well as custom designed options. Our standard GUARDIAN VRU designs are based on very robust and highly reliable rotary screw compressors (most suitable for heavy and wet tank vapors) with both electric (20 - 125 HP) and gas driven motors delivering up to 300 PSIG discharge pressures. Our NEW standard GUARDIAN HP VRU designs are available with electric drives (10-60 HP) and based on industry-proven reciprocating compressors that provide discharge pressures of up to 1200 PSIG. Additionally, the GUARDIAN and GUARDIAN HP Series VRU comes packaged with state-of-the-art Allen-Bradley HMIs for improved infield operability and ease of use. Extreme weather packages are available as optional equipment. These VRU series can also be customized to specific customer requirements.

The SENTRY Series VRU is a more basic and cost effective VRU model that is only available in standard sizes in both electric (10-100 HP) and natural gas drives (4, 6, & 8 cylinder engines). The SENTRY VRU is a very reliable unit based on a rotary screw compressor design that comes with a very compact skid-based footprint. This standard design series is not available with extreme weather packages and cannot be customized.

No matter what VRU you buy from AEREON, they are all backed by leading warranties and local service teams that can help commission and maintain your units. Contact us for a VRU solution to fit your needs. Purchase and/or lease options are available.
