Raymax ® 1220 and
2030—Ideal For Many
Process Heating
Applications Requiring
"Hot Face" Temperatures
Easy to install and capable of high surface temperatures, the
RAYMAX
® 1220 and 2030 are ideal for many process heating
applications requiring "hot face" temperatures above 540 O C
(1000 O F).
Each unit consists of a ceramic fiber heater mounted in a 2.5 inch
(64 mm) deep sheet metal case that provides thermal insulation.
The case includes post terminals for electrical connections and
provides a mounting system that can be used with virtually any
flat ceramic fiber unit, whether it is a stock, standard or a custom
size. Since any of the flat unit heating element configurations can
be used—exposed sinuated, embedded coil or foil elements—
watt density and temperature capabilities can be tailored to meet
specific radiant applications.
