Radiant Heaters RAYMAX Panel Heaters RAYMAX 1220 and 2030 Easy to install and capable of high surface temperatures, the RAYMAX 1220 and 2030 panel heaters are ideal for many process heating applications requiring “hot-face” temperatures above 1000°F (540°C). Each unit consists of a ceramic fiber heater mounted in a 21/2 in. (64 mm) deep sheet metal case providing thermal insulation. The case includes post terminals for electrical connections and a mounting system that can be used with virtually any flat ceramic fiber unit. Since any flat unit heating element configuration can be used—...

Radiant HeatersRAYMAX Panel Heaters RAYMAX 1220 and 2030 Applications and Technical Data Application Hints A thermocouple mounting clamp is provided on one end of the case, with holes on both ends for alternate locations. The clamp can be used with 1/8 in. (3.2 mm) outside diameter sheath thermocouples. The clamp is 3/16 in. (4.8 mm) high, but can be removed for flush mounting*. The heater’s maximum recommended surface temperature is based on the rating of the ceramic fiber heater module. This can vary from 2000°F (1095°C) at lower watt densities, to higher watt densities at reduced surface...

Radiant Heaters RAYMAX Panel Heaters Mounting Accessories Terminal Accessories Mounting Studs Standard 1/4-20 x 11/2 in. (38 mm) or (M6-1 x 40) steel studs are welded to the case. For best support, studs should be approximately located on 12 in. (305 mm) centers. Contact your Watlow representative for exact locations on specific heaters. Available with RAYMAX 1220 and 2030. To protect electrical connections, a standard NEMA octagon terminal box is available. The standard size is 39/16 x 39/16 x 11/2 in. (90.5 x 90.5 x 38 mm) with knockouts for 1/2 in. (13 mm) conduit. Other NEMA sizes are...

Radiant Heaters Extended Capabilities for RAYMAX Panel Heaters Zoning Exte n d e d Ca pa b i l i t y Wiring Raceway 3 in. (76 mm) 1¾ in. (45 mm) Watt densities can be varied across the entire width of RAYMAX heaters. If desired, each zone can have an individually controlled power supply. A steel raceway provides electrical and physical protection for all terminal connections. This can be particularly useful for multi-zone panels. Available as an extended capability for RAYMAX 1220 and 2030. Zoning can be very valuable when part of the product requires more heat, or when it must compensate...
