THE LATEST INNOVATION FROM POWEREX LABORATORY VACUUM SYSTEMS OPTIONAL AUTO PURGE CONTROLS • Extremely reliable because of proven claw and oil sealed rotary vane technologies • Great for applications in the research field—from simpler applications like a high school chemistry lab to more complicated applications in biomedical research and everything in-between • Multiplex systems have built in redundancy capabilities • Systems built under same standards as all our medical air and vacuum life support systems • HMI, PBMI and Basic controls available • Optional auto purge control feature available with HMI or PBMI controls Knowing the type of research, application and what process gases are being used are key in determining the best vacuum pump technology—lubricated vane or claw—to use for your laboratory application. Our sales team can help you select one of our standard systems or work with our engineers to design a custom a system to fit your needs. Oil Sealed Rotary Vane Pump • PLC controller and 6” color HMI (Human Machine Interface) touch screen displays the operating status of the unit • UL508 listed and labeled, NEMA 4/12 enclosure • Visual and audible alarms for: - System overload trip - High temperature conditions - Service intervals • Panel door includes: - Audible and visual alarms with an acknowledge button - HOA switch for each pump Product Selection Guide • Air or electric auto purge control options available Auto purge controls are available as an option for those processes requiring a fresh air flush before shutting down the off load pumps. The minimum run and auto purge functions are combined in the control as appropriate. Pumps will run through an automatic purge cycle every 60 minutes (after alternation phase), to purge any gases from the pump to atmosphere. A 3-position switch is provided to select automatic purge, manual purge, or purge off modes. The screen shot to the left simulates a quadplex system, with pumps 1 and 2 making vacuum to meet demand, pump 3 purging and pump 4 in ready mode should demand increase. Auto purge features include: Claw Pump Laboratory Vacuum System Design • Includes: - Vacuum pumps - ASME receiver - Control panel (HMI, PBMI, or Basic) - All interconnecting piping and wiring - Vibration isolation pads and flex connectors • Built in redundancy in multiplex systems • Manufactured in ISO 9001 UL certified facilities • Optional auto purge feature (air or electric) with HMI or PBMI controls • 15 min. purge cycle per pump • Pump will be put away clean (after completed purge cycle) when it is not needed to meet demand • Low vacuum alarm which indicates high usage or service requirement for other pump(s) Control Panel Options: HMI, PBMI Or Basic Powerex offers three different control panel options for our Laboratory Vacuum Systems — HMI controls as our standard and optional PBMI or Basic controls. Standard HMI Control Panel: Laboratory Vacuum Systems • Provides extra protection for pumps by performing a fresh air flush before shutting down Optional PBMI Control Panel: • All features of the standard HMI control panel • Building automation gateway with BacNet® protocol • Email notifications for alarms and service alerts Powerex Building Management Integrator (PBMI) Our standard auto purge option will use a pneumatic actuated valve. The electric auto purge option will use an electric valve. Optional Basic Control Panel: *Please specify which (air or electric) auto purge option you would like when ordering. • UL508A listed and labeled, NEMA 12 enclosure • Power on light • Timed lead/lag pump alternation • Reserve pump in use alarm— NOTE: This option is available for systems with Standard HMI controls or Optional PBMI controls. It is not available on systems with Basic controls. visual and audible • Redundant control circuit transformers • Dry contacts for remote alarm monitoring • Horn silence and lamp test pushbuttons • Each pump provided with: FOR MORE INFORMATION, CONTACT YOUR LOCAL DISTRIBUTOR OR POWEREX SALES REPRESENTATIVE. - Externally operable motor circuit breaker - Hand/Off/Auto selector switch • Packages that leverage proven Dry Claw and Oil Sealed Rotary Vane Technologies • Easy to use product guide with control panel options and product specification charts to help you find just the right product - Minimum run timer - Run hour meter • Vacuum systems customized specifically for Laboratory Applications
