High Intensity Quartz Faced Radiant Heater

Highest Watt Density Available of any Medium Wave Infrared Radiant Panel Heater — Due to thermal and electrical properties of the grooved quartz face plate, CPHI has the highest watt density (5.76 kW/Ft2) of any medium wave infrared radiant panel.

Uniform Radiation Pattern Assured with a wide flat infrared surface versus the line pattern given in normal radiant heaters. This eliminates uneven heating of the work and allows uniform heating of a stationary surface such as in an indexing process.

Lower Operating Cost with up to 80% of the input energy transmitted to and absorbed by the work material. The maximum amount of radiant energy is transferred to the work with very low heater convection losses. Typical installation distance of two to four inches from the work surface significantly reduces the energy input.

External Reflectors Not Required — The refractory board and bulk insulation behind the heating element help prevent back heat loss. This eliminates the need for external reflectors.

Costly Downtime Minimized — There is no deterioration of the output radiation level with heater life and no reflectors to clean which could cause downtime and increased maintenance costs. The unit is resistant to vibration because of the compact homogeneous construction.

Easy Installation — The light weight building block approach allows for a modular installation which is easily expandable.

Note — CPHI heaters mount only so that the coil direction is in the horizontal plane.

Repeatable Process Performance Assured — Used with closed loop control, the system automatically compensates for ambient temperature ranges and line voltage fluctuations. Maximum energy transfer requires matching the peak wavelength output to the specific material absorption characteristics. Because the peak wavelengths of the flat surface heater are repeatable and adjustable, the quality output of the process is assured.

Heating Element — Precision iron base resistance wire, designed to give extended life and uniform emission over entire radiating surface.

Emission Surface — Grooved fused quartz face plate for CPHI type heaters. Special ratings with aluminum emission surfaces are available for applications such as in the food industry.

Frame — Heavy gauge, heat-resistant aluminized steel.

Heating Element Support — Fibrous ceramic material specially developed for high insulation qualities, durability, shock resistance, asbestos free.

Insulation — Hight temperature insulation to minimize heat loss from back of heater.

Terminals — Stainless Steel terminals in a 4 x 4" junction box are provided with CPHI type heaters.

Thermowell — Quality tubular quartz thermowell, with strain relief, to accept a Chromalox C-700JU or C-700KU thermocouple on units with suffix T in model number. Standard placement of thermowell is on side of heater. Specials are available with thermowell exiting back of heater.
