Temperature Control Panels – Standard Design For Industrial Process Applications

Design Features
  • NEMA 12 enclosure
  • Model TEC-4100 1/4 DIN or TEC-9100 1/16 DIN temperature control, dual display with auto-tuning
  • Model TEC-410 1/4 DIN or TEC-910 1/16 DIN high limit control with FM approval and manual reset pushbutton switch
  • Main Power: 240 or 480 VAC, single or three phase
  • Fused turn handle disconnect



Heater Power Output
  • SCR output device and fused sub-circuits
  • Solid state relays with individual relays per fused sub-circuit
  • Mechanical or Mercury relays
These standard control panels range in capacity from 4.8KW through 332KW and use NEMA 12 enclosures.
The general purpose control panels are set up to run process heating systems such as circulation, duct heaters or any other resistive load.
All control panels are shipped factory pre-wired according to the National Electrical Code, eliminating the need by the customer to design your own control system, purchase separate components and construct your own working temperature control system.
The standard temperature control systems are supplied with the standard features listed. They are based on SCR power controls, solid state or mechanical relays. Panels designed using Mercury Relays are available on request.
  • Power on pilot lamp
  • Control transformer, fused secondary
  • Power output connections hardwired to fuse holders
  • Sensor input connections at labeled terminal strips
  • Ventilation fan and filter standard for systems over 15KW
  • Tagging of door-mounted parts with 2-color engraved phenolic labels
  • 1 set of wiring schematics and control manuals


Silicone Controlled Rectifier (SCR) Power Controls are a solid state device that provides infinitely variable power to accurately maintain setpoint temperature and extends heater life by maintaining a stable process temperature. Control panels with SCRs that utilize cooling fans require a minimum of 6 inches clearance on both sides to allow for proper air flow.
    • Single-phase systems use single-phase zero cross
       SCRs.
    • Three-phase systems use 2-leg three-phase zero
       cross SCRs.

Solid State Relays offer many of the benefits of SCRs but often at a lower cost. Maintenance costs are potentially lower due to less costly SSRs used per control circuit.

Mercury Relays offer a low-cost alternative to SCRs and SSRs for process heating applications and provide longer life than a mechanical contactor due to their self renewing mercury contacts.
