Raymax Radiant Panel Heater

Radiant Raymax Panel Heater

Raymax® Radiant Panel Heaters

Watlow's Raymax® Radiant Panel Heaters are ideal for process heating requiring "hot-face" temperatures above 1000°F. Applying radiant panel heaters can be complicated. However, Valin’s engineering staff has the level of training and expertise required to meet most application requirements. Valin provides a high degree of technical support such as calculating the watt density and temperature requirements and recommending system components such as sensors and controllers.

Performance Capabilities

  • Maximum face temperature up to 2000°F (1095°C)
  • Maximum watt densities up to 30 W/in² (4.7 W/cm²)

Features and Benefits

  • Engineering and application support helps projects run smoothly
  • Sensors and controllers are completely compatible with RAYMAX heaters for a single-source, customized thermal system
  • Light weight, Low mass design
  • Variety of styles match the ideal temperature and watt density requirements of the application

Typical Applications

  • Thermoforming
  • Food warming
  • Paint and epoxy curing
  • Heat treating
  • High-temperature furnaces
  • Tempering and annealing processes


  • Moisture and Explosion Resistant Terminal Enclosures and High temperature stand-off enclosures
  • Alloy 800 and 840, Laminated alloy 600 (high-temp), Hastelloy® C276, 304, 316 and 321 stainless steel sheath materials
  • Type J or K thermocouples, inserted in the thermowell, to accurately sense element sheath temperature for over-temperature conditions.

Raymax Radiant Heaters Series 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—exposed sinuated, embedded coil or foil elements—watt density and temperature capabilities can be tailored to meet a specific radiant application.

Performance Capabilities

  • RAYMAX 2030 (uses sinuated or coil elements): temperatures up to 2000°F (1095°C); watt densities up to 30 W/in² (4.7 W/cm²)
  • RAYMAX 1220 (uses an etched foil element): temperatures up to 1200°F (650°C); watt densities up to 20 W/in² (3 W/cm²)
  • Maximum voltage up to 600V

Features and Benefits

  • Lightweight, low mass design allows fast response to controllers
  • Self-insulation with 21/2 in. (64 mm) thick mounting case provides high efficiency
  • Thermocouple mounting clamp makes process system control easier
  • Aluminized steel case handles temperatures up to 1100°F (595°C)
  • Special hot-face heating patterns provides a design made specifically for an application using an etched foil RAYMAX 1220

Typical Applications

  • Conveyor furnaces
  • High-temperature vessel heating
  • Tempering and annealing processes for glass, wire, ceramics and metals
  • Coating, curing and drying of inks, paints, plastics and films
