The only balance system currently available to meet the CA EVR Phase II requirements.

Springboro, Ohio – USA – May 6, 2008, – Vapor Systems Technologies, Inc. (VST) is pleased to announce the addition of Veeder-Root’s In-Station Diagnostic (ISD) approval for VST’s Phase II Enhanced Vapor Recovery (EVR) equipment with a new certification issued by the California Air Resources Board (CARB). VST is now positioned to support any gasoline dispensing facility (GDF) regardless of annual throughput with Executive Orders VR-203 and VR-204.

The VST ENVIRO-LOC™ Total System Balance Solution has demonstrated a robust efficiency greater than 98%, which exceeds the currently mandated CARB EVR standard criteria of 95%. VST’s EVR system includes all of the necessary hanging hardware for dispensing fuel; including EVR approved, state-of-the-art dripless vapor recovery fueling nozzles, hoses, safety breakaways, and is combined with a unique membrane processor that continuously controls the pressure in underground storage tanks (UST) to below atmospheric pressure levels.
