most versatile & widely used source of
electric heating for industrial,
commercial & scientific application.
These are used in force air heating,
thermal forming M/C, direct immersion in
liquids, comfort radiant heaters, welded
brazed or clamped to tanks & pipes hot
runner molds, radiant & convection
heater for ovens & dryers.
heaters are swaged construction provides
maximum support to resistance wire.
They can be designed in a wide range of
electrical ratings, diameters, length,
terminations & sheath material.
Important & useful characteristic of
tubular heaters are that they can be
formed in to virtually any shape, brazed
or welded to any metal surface and cast
in to metals.
Resistance wire is fusion welded to the
steel terminal cold pins. These coils
assembly is precisely stretched &
centered in the element metal sheath
which is than filled with grade 'A'
magnesium oxide powder (Mgo). Swaged to
reduced diameter into solid mass,
permanently stabilizing the coil in
center while providing excellent heat
transfer & dielectric strength between
the coil & the sheath.
Working Temperature :
temperature upto 200°C
can be used any of the heaters, in the
range depending upon the space
available. Air heater for higher
temperature can be designed on request.
Sheath material are as Inconal :- 800°C;
ss 304; 321; 316; upto 600°C; copper:-
177°C Mild Steel:- 350°C
While Placing Order :
Please mention diameter, length,
wattage, voltage, lead wire length,
special features if any.
