Heater Control Panel

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.

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.

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.
