Barber Industries' 'Rigsaver' Assures Mobile And Stationary Engine Overspeed Protection

Barber Industries' Rigsaver® is a positive spring-operated, engine intake air-shutoff device, intended primarily for emergency shutdown service. This protective device provides unrestricted straight-through air flow with minimal pressure drop. The Rigsaver will positively stop a diesel engine when the presence of hydrocarbons in the atmosphere or mechanical failure causes engine runaway. The Rigsaver can be manually or automatically controlled, responding to a variety of fault or hazard conditions. Over 4,000 Rigsavers have been sold worldwide, providing reliable service on and offshore under the adverse conditions associated with locations in the Canadian Arctic, the Gulf of Mexico, the North Sea, etc.

The Rigsaver is available in a wide range of sizes to accommodate virtually the entire range of available engine displacements—from the small fork-lifts to giant offshore platform engines. The Rigsaver is offered in two series: the GT series, available in through-port diameter from 2.5 inches to 8 inches, and the new compact SG series, available in through-port diameters from 3 inches to 14 inches.

The SG (swing gate) series Rigsaver was developed to permit easier installation on engines crowded with turbochargers and other accessories, and for use in tightly cowled installations. When compared with the GT series, the SG series offers several additional advantages. The SG series will withstand considerable higher ambient and induction air temperatures.
