In the event of a fire, significant amounts of water may be discharged from a building’s elevator sprinkler system. This discharge can create several safety challenges for firefighters needing constant elevator access during emergencies. ParkUSA’s EleVader® is a product used to pump out liquids (usually oil and water) from the elevator pit. The unit is a passive gravity flow system for the separation of oil from oil-water mixtures. The design utilizes the difference in specific gravities between oil and water (buoyancy force) enhanced by the use of patented coalescing plates. The separator is designed to receive oily water by gravity flow and to process it on a once-through basis. The separator vessel is constructed of high strength precast concrete. The coalescing plates are manufactured of an oleophilic polypropylene.
The system is a complete, fully integrated, and packaged system which contains required alarm features. Per the ASME A17.1 Safety & Building Code, a sump pit and pump (50 GPM each shaft) shall be provided for all elevators with firefighter emergency operation. The code is to ensure the removal of water from the shaft, regardless of what contaminants are present. The EleVader is specially designed for this application.
The system is compliant to all plumbing codes (i.e. UPC, IAPMP). Providing high efficiencies on oil removal and flow treated, the ParkUSA EleVader is leader in the market for these types of applications.

The ParkUSA Elevator Oil-Water Interceptor is available with the following components:
- Steel Separator: The Separator is located freestanding (Model ES) on the floor near the shaft, floor or wall mounted (Model EX) or can be located outdoors (Model EC) & buried below grade. The separator is rated from 50 to 400gpm depending on the quantity of elevator shafts to be served.
- High Oil Alarm Panel (intrinsic safe): Indicates “High Oil Level” of the separator, in the event of a high accumulation of oil. The panel has a “Separator High Level” light & horn, a “Silence” button, and an auxiliary contact for a BAS System.
- Pump Control Panel (intrinsic safe): The Control System consists of float sensors and a unifi¬ed control panel (NEMA 4X weatherproof) that is wall mounted near the elevator shaft.
- Elevator Sump Pump (explosion proof): Submersible Sump located in the sump area of the elevator. Each hoistway is required to have a pump capable of removing all fluids at 50 GPM per elevator car.
The Oil-Water Interceptor is generally sized according to the local plumbing code. States that have adopted ASME A17.1 require that each elevator be able to remove 3,000 gal/hour. A typical method to determine the total fixture unit loading of the interceptor is to multiply the number of elevator cars times 50 gpm and allow for any additional fixture units designed to drain to the interceptor.
