RAYMAX®1220 AND 2030

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
applications requiring "hot face" temperatures above 540
(1000

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.

Applications and Technical Data

Specifications

Weight: Under 6.5 lbs/ft2(31.75 kg/m2)

oltage and Wattage:Ratings are based on the ceramic fiber

V

heater module, which is mounted in the case. Up to 600V
is possible.

Terminals: Terminals are 1⁄4-20 threaded studs. Two terminals
plus ground for single-phase, and three terminals plus ground
for three-phase, are standard. They will be located on the center
line of the length unless otherwise specified. Terminals can be

ocated anywhere along lines A and B (see illustration), but not

l
closer than two inches (51 mm) to the case ends.

Options

Several options are available with RAYMAX 1220 and 2030
models. Consult Watlow for more information on any of the
options.

Mounting Legs

• One inch (25 mm) standard

• Three inches (76 mm) optional from stock. For made-to-order

units, mounting legs can be supplied in any incremental
length L from

1

⁄2 inch (13 mm) to three inches (76 mm). No

slots are provided in legs less than one inch long.

Application Hints: A thermocouple mounting clamp will be
provided on one end of the case, with holes on both ends for
alternate locations. The standard clamp can be used with
(3.2 mm) O.D. sheath thermocouples. The standard clamp is

3

⁄16inch (4.8 mm) high, but can be removed for flush mounting*.

The maximum recommended surface temperature of the heater
is based on the rating of the ceramic fiber heater module. This
can vary from 1095°C (2000°F) at lower watt densities, to
higher watt densities at reduced surface temperatures. Note that
maximum wattages cannot be achieved at the maximum
temperatures simultaneously.
