The refractory board and bulk insulation behind the heating element help prevent back heat loss. This eliminates the need for external reflectors. 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. The light weight building block approach allows for a modular installation which is easily expandable.
CPHI heaters mount only so that the coil direction is in the horizontal plane.
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. CPHI heaters produce micron levels between 2.5 and 6.0. At these micron levels the majority of the CPHI heaters fall into the middle of the IR spectrum, categorizing them as medium wave heaters.
