G-Series Specifications

Glass is the standard face on the G-Series panel heaters. The G-Series uses a high-temperature (1202°F/ 650°C, continuously operating temperature) black glass. The construction of the G-Series heater is similar to that of the F-Series heater with the exception that glass replaces the quartz composite fabric as the face material.

The glass face G-Series heater is used for industrial applications in which there is a possibility that materials will fall onto the heater's face. A glass face allows for easy clean-up and prevents damage to the heater or heating element. Common applications for the G-Series heater include operation as the bottom oven in a thermoforming machine and as the bottom heater in a wave solder oven.

The G-Series heater can be constructed as wide as 24" (610 mm) and as long as 36" (914 mm), though not that width and length in the same heater. For example, a 36" (914 mm) long heater is commonly 12" (305 mm) wide. This heater has a maximum watt density of 20 watts/in2 (31 kW/m2) and a durability defined by a typical life expectancy of 25,000 hours. It has a high radiant efficiency of 77.5%. Because the heater's design does not depend on an external reflector, the heater maintains a consistently high radiant efficiency over time. The G-Series heat transfer rate for 20 watts/in2 (31 kW/m2) is 1.9 Btu/ft2/sec. delivered to the product.

M-Series Specifications

Metal is the standard face on the M-Series panel heaters. The face can be manufactured using either hard-coated aluminum or porcelanized steel. The remaining construction is exactly the same as that used in the G-Series heaters. The heater's face can be provided with air holes for forced airflow, as is done in the FBA's construction.

A metal face is used for industrial applications in which there is a possibility that materials will fall onto the heater's face. Although a metal face heater is more durable than a glass face heater, a disadvantage, however, is that the radiant efficiency of metal is slightly lower than that of glass. Because a glass face heater allows a portion of the infrared energy to transmit through the glass, only a segment of the infrared energy is absorbed by the glass and re-radiated. A metal face heater, on the other hand, absorbs all of the energy and re-radiates it to the process. Especially demanding applications sometimes require a slightly different design that makes use of a hard-coated aluminum face constructed in a cap (pan) style. This design ensures that materials definitely can not penetrate the heater.

The M-Series heater can be constructed as wide as 24" (610 mm) and as long as 48" (1219 mm), though not that width and length in the same heater. For example, a 48" (1219 mm) long heater is commonly 12" (305 mm) wide. This heater has a maximum watt density of 10-15 watts/in2 (15.5 - 23 kW/m2), depending on which metal face is used, and a durability defined by a typical life expectancy of 25,000 hours. It has a radiant efficiency of 64%. Because the heater's design does not depend on an external reflector, the heater maintains a consistently high radiant efficiency over time. The M-Series heat transfer rate for 10 watts/in2(15.5 kW/m2) is 0.786 Btu/ft2/sec. delivered to the product.

G-Series and M-Series Panel Heaters

Heaters in the G-Series and M-Series product lines use a high-temperature material for their surface face. All heaters provide a uniform coverage with a convenient, cleanable surface.

Features:

  1. Glass or metal emitter surface material
  2. Ceramic standoffs used to keep electrically conductive material separated from resistance wire
  3. High-temperature cement bond
  4. Refractory board to hold resistance wire
  5. Precision-resistance wire
  6. Heavy gauge aluminized steel frame
  7. Blanket insulation layer
  8. Ceramic bushings to insulate terminals
  9. Stainless steel terminals
  10. Quartz thermowell tube (optional)

Glass Face Warm-up Curve

The warm-up curves are measured from heaters running facedown in open air. The thermocouple is located in a standard location inside a thermowell behind the coil. The curves will change depending on the environment and thermocouple location.
