CBH Series heaters are constructed
of rugged metal sheathed tubular 
elements homogeneously combined 
with a metal sleeve that has been 
accurately dimensioned to provide a 
proper clearance and ease of 
inserting into standard drill hole 
sizes so large bolts or studs may be 
rapidly expanded and tightened with 
a wrench, providing ‘’shrink fit 
tightness” when cool
Useful in assembly of large 
compressors, presses, turbines, die 
blocks, cylinders, engine heads, 
pressure vessels, etc. Quick heat-up 
is important to avoid heat drain-away 
of surrounding metal. CBH heaters 
are generally used in sets to permit 
uniform tightening of mating parts.

†
Hole diameter should be held as close to heater diameter as possible for maximum heat 
transfer and heater life.
Designate voltage, Insert “120” for 120 Vac or “240” for 240 Vac. 
*
Those model numbers containing /120, /240, or /480 are available only in that voltage.
