Shand & Jurs (L&J Technologies & L&J Engineering) products

The Shand & Jurs Model 94261 Vapor Recovery Regulator is a float-operated pressure regulator utilizing a weight balanced float to establish a set point. This highly accurate and extremely sensitive regulator is used to maintain close pressure control of low pressure tanks and meets requirements for vapor recovery.

Gas blanketing systems are used to prevent the escape of liquid vapors into the atmosphere or to prevent moisture from entering a tank and contaminating its contents. A tank blanketing valve maintains an inert gas blanket (usually nitrogen or carbon-dioxide) in the vapor space of a pressure-tight liquid storage vessel. This process is accomplished by utilizing a steady high-pressure gas source and the Shand & Jurs Model 94270 "VAPOR GUARD" so that flow is limited to a constant value when the main valve is opened below the set point.

The Shand & Jurs Model 94320 Dehydrator absorbs moisture from the air that is drawn into a storage tank during the unloading of product or by "thermal breathing" conditions.

The Shand & Jurs Model 94321 Air Dryer absorbs moisture from the air that is drawn into a storage tank during the unloading of product or by "thermal breathing" conditions. Desiccant of high absorptive capacity is used as the drying agent. The hard ball shaped form of the desiccant minimizes the pressure drop, permitting more efficiency. This is a function of material surface area and retention time. The nature of the desiccant does not change the flow of gas up to the point of maximum saturation since the moisture is absorbed within the pores of the material. The desiccant is contained in a perforated stainless steel basket that can be easily removed for cleaning or maintenance.
