Control System

LEWCO’s standard control package includes a single set-point process temperature controller and redundant high-limit controller. Circulation fan(s) and exhaust fan(s) include air proving circuits that are electrically interlocked with the heating circuit. All controls are housed in a NEMA 12 enclosure employing a full voltage lockable disconnect switch. Controls are wired to NFPA 70 and 79 electrical standards in our own UL508A certified panel shop. These models meet the requirements of NFPA 86, Class B ovens Independent third party inspections available.


  • Batch Timer: Infinitely adjustable up to 100 hours; includes illuminated On/ Off switch to indicate timed operation and audible alarm when time has elapsed.
  • Data Logger: Multiple input digital data logger continuously records temperature and other process data. Allows downloading of digital data files through USB or Ethernet connection. Data can also be viewed on a full color display or on a web server when connected to a network.
  • Door Switch: Automatically disables heat when door is opened.
  • Ramp/ Soak Controller: Programmable ramp/ soak temperature controller with capability to store different recipes with multiple segments.
  • Zero Speed Switch for Fans: Minimizes nuisance tripping associated with standard airflow switch(s).

Standard tote oven construction includes an all welded 1/8″ steel shell with 4″ x 6# mineral wool insulation. Heat loss is minimized by a proprietary wall design featuring a welded inner shell and a completely isolated outer frame and covers. This model features top-mounted lifting eyes for easy installation and transportation.

LEWCO High-Performance Tote Ovens are designed and manufactured to industry standards. Our engineers stay current with the latest revisions to these standards. If there is a specific industry standard or code compliance that you require for your process heating application, please contact one of our highly knowledgeable Applications Engineers to learn how LEWCO can help!

As standard, High-Performance Ovens are designed and manufactured to meet the requirements of NFPA 86, Class B ovens. This model is not suitable for applications involving the off-gassing of flammable volatiles, or for installation in electrically hazardous locations. Consult factory for non-standard features required for compliance with NFPA 86, Class A ovens.

About NFPA 86

The National Fire Protection Association’s standard, NFPA 86, documents the guidelines for the safe operation of industrial ovens and furnaces. Oven and furnaces in which flammable volatiles or combustible materials are present in the work space are classified by NFPA 86 as “Class A.” Similarly, ovens and furnaces in which no flammable volatiles or combustible materials are present are classified as “Class B.” Due to the risk of fire or explosion, NFPA 86 requires specific safety equipment for all Class A ovens and furnaces.

  • Powered exhaust of capacity determined by maximum solvent loading.
  • Explosion relief of adequate area determined by oven or furnace workspace volume.
