CAMX 2019 exhibit preview: LEWCO

 

LEWCO (Sandusky, Ohio, U.S.) is featuring its line of convection oven systems for out-of-autoclave (OOA) composites curing application. The company is emphasizing its knowledge and experience with composites fabrication, and its ability to meet common aerospace specifications for temperature uniformity, heat-up rates, controlled cooling rates, vacuum controls, etc. Additionally, LEWCO Ovens are designed to meet current standards, such as AMS2750E and BAC5621.

LEWCO’s composites curing control package includes a multiple recipe ramp/soak temperature controller, redundant high-limit controller and a multiple-input digital data logger, which continuously records temperature and other process data. The data logger also allows downloading of digital data files through USB or Ethernet connection. The company’s stantard programmable logic controller allows easy control of processes with numerous inputs and outputs, or processes that require automation of material handling equipment. The PLC can also allow for Ethernet connectivity for remote system monitoring.

Circulation and exhaust fans include air-proving circuits that are electrically interlocked with the heating circuit. All controls are housed in a NEMA 12 enclosure and employ a full voltage-lockable disconnect switch. Controls are wired to NFPA 70 and 79 electrical standards. Other third-party certifications are also available.
