Crossflow Blower Heaters by Farnam

Crossflow Blower Heater

The Crossflow Blower Heater (CB Series) was developed for maximum design flexibility. These air heaters utilize multi-purpose mounting brackets to attach directly to the exhaust of a crossflow blower without the need for additional accessories. Or, use the extra mounting holes and the heater can function as a stand-alone duct heater.

Single wattage, dual wattage, or dual voltage combinations are available. Over-temperature protection can be provided with an integral thermal fuse and hi-limit thermostat.

These crossflow blower heaters are tailored to meet your specific heating requirements. Size, wattage, and voltage are matched to your specifications for optimal system performance.

We can provide heater/blower packages. See the part number and ordering information for available stock blowers.

B - 70°C (158°F)
C - 80°C (176°F)
D - 85°C (185°F)
E- 90°C (194°F)
F - 100°C (212°F)
G - 120°C (248°F)
H - 130°C (266°F)
J - 150°C (302°F)

If a thermostat is specified,
it must be used in conjunction with a thermal fuse.

Thermal Cutoff
(Thermal Fuse)
X - No fuse
D- 93°C (199°F)
F - 104°C (219°F)
H - 117°C (243°F)

L- 152°C (306°F)
N - 192°C (378°F)
R - 229°C (444°F)

Fuse setpoint is a minimum 25°C above thermostat setpoint or routine temperature spike.

Heater Size
5-5.55" long
7-7.91" long
10-10.32" long
12-12.72" long

Termination
M - Standard. Stripped leads. Contact factory for options.

Lead Length
Specify length required. Standard lead length is 6". Ex. 12=12" long leads.
