CHICAGO (Aug. 1, 2:20 p.m. EDT) — Logic Corp. Inc. of Sandy Hook, Conn., is beginning field testing of its Vac-U-Safe negative-pressure hot oil and water unit. The system aids molding operations lacking central air conditioning.
Logic President Paul Allen exhibited a Vac-U-Safe prototype. He started work on the idea in January and applied for a patent in June. Vac-U-Safe prevents the temperature in a molding environment from governing processing parameters. It can overcome changes in cooling water temperature, water pressure and power voltage changes. A plant operator programs set points to trigger adjustments as room temperature or cycling changes occur.
