Cleanable valve launched

Mac Process, North America’s largest design/build pneumatic conveying and air filtration systems engineering firm, today launched the new CRA (Cleanable Round Airlock) valve.  During the past two years, Mac Process engineers have increased the use of de-mountable-style valves in dry material pneumatic transfer systems to help customers meet challenging requirements for sanitation and inspection. With the launch of the CRA valve, Mac Process has taken an important step in a visionary Clean Design Initiative, which will supply a complete line of engineered and manufactured cleanable solutions for food and pet food customers.

Offering the largest cubic feet per revolution capacity —a critical improvement —the CRA can handle extremely high process rates on products. Now high end food and pet food manufacturers can use cleanable technology in systems where high product volume demand may have prevented their use in the past. The tool-free CRA valve operation makes it easier for customers to clean their equipment after a campaign is finished to prevent bacterial growth and facilitate inspections.

“We listened to customer requirements and are bringing to market Clean Design Initiative manufactured solutions that addresses their needs. When 3A Dairy equipment isn’t required by the application, the CRA valve brings a new standard of safe food design without added cost or complexity,” said Jay Brown, President and CEO of Mac Process. “Best of all, as a single source supplier and manufacturer, we’re able to improve control over lead time and quality.”

The high quality, high performance CRA valve is available in four models: CRA8, CRA10, CRA12, and CRA14. Oversized rotor shafts create a naturally radiused rotor pocket, promoting product release and sustaining throughput efficiency. Mac Process CRA valves have considerably less rotor deflection than other valves on the market. Components used in product contact areas, including the seals, are constructed of FDA approved materials and all lubrication in and out of product zones are NSF H1 and H2 rated. Design is also available for NFPA 69 isolation valve requirements.

Also part of the new Clean Design Initiative from Mac Process— the newly designed SEntry filter will be on display at the 2012 PXTi show. Patent pending revolutionary design will help food and pet food producers comply with today’s challenging industry sanitation requirements, while minimizing operating and maintenance costs.

The SEntry is a side entry cartridge filter with tool-free cartridge removal. Confined space entry safety concerns are eliminated. Unique cleanable design model significantly decreases maintenance and provides easy access for cleaning and inspection.

Designed for low headroom applications, this versatile collector can be used as a dust collector or as a primary receiver in pneumatic conveying applications. Vertical explosion venting makes the SEntry collector ideal for applications within a plant where there is no access to an exterior wall to vent through.
