Heater Control Panel

HEATER CONTROL PANELS

Gaumer Process heater control panels are specifically selected and designed to fulfill the control requirements of most process heating applications. Gaumer Process offers Nema 12, Nema 4, and Nema 7 standard panel enclosure to fit a wide variety of elecric heat control needs.


Nema 12 control panels are gasket enclosed and suitable for most indoor industrial applications. Enclosures are finished with factory applied and baked acrylic resin.


Nema 4 control panels are gasketed enclosure with stainless steel hardware suitable for most outdoor non-hazardous industrial applications. Enclosure is finished with factory applied and baked acrylic resin.


Nema 7 control panels offer a machined aluminum cast enclosure and are rated for hazardous locations. Location classifications include Class 1, Group D, Div. 1 and 2. Contact us for more location information.



Standard features include:

  • Heavy gauge gasketed enclosure finished in grey Epox
  • Integral "Dead Front" switch
  • "Off-On" Control Power selector switch
  • "Power-On" pilot light
  • Illuminated reset button
  • Digital indicating electronic temperature controller Circuit breaker with mechanism
  • Control transformer with fused primary lines and fused/grounded secondary lines
  • "Zero Fire" type SCR assembly with external cooling, Three pole safety magnetic contactor(s)
  • Electronic over-temperature controller
  • Fast acting fuses for circuit protection
  • Terminal strips for customer connections
  • Safety relay button to ensure safe shut down and the ability to enable systems remotely



Some typical methods of power control and/or temperature control are contractor control, stepper SCR control, or full SCR control. Additionally Gaumer Process can custom temperature control panels to meet your specific needs.

HEATER CONTROL PANEL TYPES

Type SCP and SCRP

SCP and SCRP control panels use zero cross (burst firing) solid state relays (SSR's) in conjuction with external heat sinks to remove heat from the panel enclosure. These SSR's are manufactured with direct copper bonding technology and a built in varistor for surge protection. The zero switching relay switches ON when the sinusoidal curve crosses the zero and switches OFF when the current crossed zero. Zero cross SSR's create very low harmonics and RFI and are much more reliable.

Type ZPA and ZPA3

ZPA and ZPA3 series control panels use zero cross (burst firing) three phase analog SCR's (Thyristors). Designed for larger electric heater loads, these panels are available in sizes from 85 to over 2500 amps.

zpa

Analog SCR

  • Four SCR for 2 Leg
  • Six SCR for 3 Leg
  • Sync-Guard to smooth out line current draw when multiple controllers are used
  • Thermostatically protected
  • Shorted SCR Detection
  • UL/cUL,CSA approval

Type ZPD and ZPD3

ZPD and ZPD3 series control panels use zero cross (burst firing) three phase digital SCR's (Thyristors). Designed for larger electric heater loads, these panels are available in sizes from 85 to over 2500 amps.
