ESCO Weighing Balance Enclosure Powdermax 0.9Laboratory operations involving weighing, mixing and dispensing hazardous or nuisance powders can now be performed safely and economically with the Esco Powdermax 1 Powder Weighing Balance Enclosure. The enclosure?s unique design maintains balance stability to 4 decimal places without compromising containment.
Designed specifically for powder containment applications, the Powdermax Enclosure employs carefully directed inward airflow at the face of the enclosure to protect the operator from exposure to hazardous powders or potent pharmaceutical compounds. The aerodynamically designed enclosure reduces airflow turbulence for maximum containment while minimizing the effect that air drafts may have on sensitive weighing balances. The enclosure design exceeds the containment requirements of ANSI/ASHRAE 110 as proven by independent type testing. All exhaust air is HEPA-filtered, removing virtually all particulate matter, before recirculation to the laboratory.
Designed for Enhanced Usability and Efficiency The Powdermax 1 is designed specifically to provide the operator with a high level of usability, comfort and visibility.
- A 13-degree sloped front allows easy access to the work zone, eliminating operator fatigue and increasing productivity.
- Transparent 6 mm (0.2") frameless acrylic front and sides enhance visibility and operator comfort during longer periods of operation. The self-supporting pre-tensioned hinges on the front window provide easy access during loading and start-up.
- Ergonomically designed apertures for hands simultaneously provide maximum movement within the work zone while protecting the operator. The curved front edge minimizes airflow turbulence and improves user comfort.
Electronic ballast for the fluorescent lighting provides zero flicker with increased energy efficiency, reliability and service life with a lower heat output.
- Two electrical pass throughs on the back wall of the unit provide convenient access to power sources for equipment.
- The spacious interior dimensions will easily accommodate large analytical balances.
Enhanced Filtration System The enclosure?s unique filtration system ensures the highest level of protection for the operator.
- The Powdermax 1 provides enhanced safety to laboratory personnel by drawing air across the front opening in the hood at a controlled rate, preventing the escape of powders and particulate matters into the general laboratory environment.
- A unique filter mounting system eliminates bypass leaks inherent in conventional clamping systems.
- The Powdermax 1 is equipped with a generously sized HEPA filter system, rated at > 99.99% efficiency for 0.3 micron sized particles.
- The aerodynamically designed system constructed of 1.2 mm (16 gauge) epoxy powder-coated electrogalvanized steel delivers maximum containment by ensuring airflow uniformity throughout the work chamber of the cabinet.
- Since HEPA-filtered air is recirculated to the laboratory, the enclosure does not have to be connected to an extraction/ exhaust system, resulting in low operating costs and mobility.
User-Friendly Control System
The user-friendly Esco Sentinel
TM micro-processor based control system is fully configurable according to operator?s requirements and comes equipped with a number of enhanced features to promote cabinet usability.
- Accurate true airflow velocity sensing technology measures all critical cabinet airflow parameters allowing superior monitoring. Temperature compensated sensors ensure increased accuracy.
- Password-protected administration can be set to restrict access to the main menu.
- Solid state variable speed controllers offer superior control over conventional "step" controllers. The built in RFI and noise filters eliminate interference with adjacent instrumentation.
- A bright, easy-to-read, LCD display provides continuous monitoring of cabinet airflow.
- Audible and visual alarms ensure operator and environmental protection by alerting the user in the event of low airflow or unsafe sash positions.
- When the cabinet is switched on, its automatic warm-up cycle is activated, purging all contaminants from the work zone prior to use.
- An automatic post-purge cycle can be configured on shutdown, purging all residual contaminants before deactivation.
Highest Quality Enclosure Construction All Esco cabinets are constructed to the highest quality using the finest materials.
- The enclosure's head unit is constructed of electrogalvanized steel with abrasionresistant powder-coated finish.
- External surfaces are coated with Esco IsocideTM antimicrobial coating to protect against surface contamination and inhibit bacterial growth. Isocide eliminates 99.9% of surface bacteria within 24 hours of exposure.
- The enclosure is supplied with a chemical and abrasion resistant phenolic resin removable work surface. The solid work surface minimizes transmission of fan vibration to the user?s weighing balance.
Blower Efficiency
The Powdermax 1 incorporates an energy efficient external rotor motor design which reduces operating costs and has extremely low noise and vibration levels. The cabinet blower system creates an inflow of air from the ambient environment into the cabinet with an average velocity of 0.4 m/s (80 fpm).
Designed and Built to Exceed Safety Criteria All components used in Esco products meet or exceed all the applicable safety requirements and are UL listed/recognized. The Powdermax 1 is compliant with International Standards. The cabinet is designed to meet the general safety requirements of EN 61010-1, EN 61326 Class B.
