LEWCO recently designed, built and installed a pair of custom curing ovens for an aerospace materials manufacturer.  The ovens are heated with thermal fluid and deliver horizontal airflow to the workspace. Strict customer design and performance specifications had to be followed.

Some Key Features of this Project Included:

  • Workspace dimensions:  60” wide X 180” deep and 100” tall
  • A circulation flow uniformity of -0% + 25% across the entire workspace—a requirement  due to the exothermic nature of the process
  • A sealed oven chamber maintaining <.1”w.c. to contain volatiles emitted throughout the curing process
  • A consistent and even heat up rate of +10°F per minute
  • material cooling from 385°F to 110°F in 10 minutes using a series of Integral bypass and fresh air dampers
  • Guillotine entry door with integral gravity roller conveyor hearth for material loading
  • OSHA compliant guardrail and access ladder to platform around oven for service/maintenance

Additionally, LEWCO’s team worked with the customer to interface this new oven with an existing PLC and PLC program, and provided a total project time of 4 months including turnkey installation services. 


  • Utility:  Electric, 480/3/60; thermal fluid
  • NFPA 86 Class A Oven, max solvent load 20lbs/batch
