Electric Motor Driven
GasVantage Rotary Screw VRU
Low Cost. High Reliability. Big Returns.
By meeting all of the Environmental Protection Agency (EPA) regulations, you are not only capturing the illegal Volatile Organic Compounds (VOC’s), but you are also able to re-sell the captured gases allowing the Vapor Recovery Unit (VRU) to pay for itself! Featuring our automated precision monitored control system with integrated blanket gas management, these VRU’s are suited to accommodate the tight control needed to maintain the low pressure range of vapor recovery.
General Information
Digital PLC Control and Instrumentation
Compressor control, monitoring, shutdown and protection for:
The BOSS® GasVantage Rotary Screw VRU’s allow your tank batteries to comply with EPA Quad O rulings. Our VRU’s are engineered around our rotary screw gas compressor that is simple to install, operate, and maintain!
The VRU compressor is a self contained, electric motor driven rotary screw compressor yet small enough to be versatile/lightweight. Rotary screw compression is ideal for this application because of its ability to effectively handle wet gas. Two asymmetrical lobe profile rotors, turning at conservative speeds in a bath of lubricant, are the only major moving parts. The rotors seal on a lubricated pitchline virtually eliminating wear since there is no rotor contact. In addition, our VRU’s can be engineered to fit your vapor recovery requirements.
The BOSS VRU Eco-Capture Series is leading the way!
