Your Bottom Line

OTA understands how operating costs affect your bottom-line. We have engineered our equipment to ensure that we are competitive in price and low in operating costs while offering a far superior product. We use components that have been vetted and proven reliable over long operating hours in the field.


OTA produces our own control panels and have developed best-in-class PLC program logic and sequencing of events so our VRUs can operate over a much larger range of conditions than competitors’ products. By changing just a few parameters, the OTA VRU can be configured for wellhead compression applications or vapor recovery applications for tank vapors, BTEX streams, glycol units, or VRTs, which gives it a high degree of flexibility to be used in a variety of operations or moved to other sites as needed.
