Aluminum Strip Heaters

Bucan Aluminum Strip Heaters combine the rugged construction of tubular heaters and the high thermal conductivity of an aluminum housing structure that acts as a heat-sink and uniformly dissipates the heat absorbed from a set of 0.315” diameter tubular elements. Bucan Aluminum Strip Heaters can have different lengths but are only available in four standard widths; 1.5”, 2.5”, 3” and 4”. They can be made with different termination styles and can accommodate thermocouple holes (max 0.25”). In order to secure efficient heat transfer Aluminum Strip Heaters should be fastened to a surface using hold-down clamps or mounting screws. Due to construction limitations mounting holes can only be placed along the dotted lines shown in the diagrams below.

Mounting Slots & Thermocouple Holes

Mounting Slots (9/32” x 5/16”) and Thermocouple Holes (1/4”) can be made along the vertical centerlines or dotted lines within the allowed limits.

B1Style


The standard termination style on Aluminum Strip Heaters. Tubular ends folded at a right angle with terminal lugs and 10-32 binder-head screws.

Stainless Steel Armor leads exiting 90 degrees with copper elbow

B2 Style


Tubular ends exiting straight from the edge of the strip heater with 10-32 stud terminals.

Stainless steel braided leads with strain relief

H Style


Encasing cables in metallic flexible tubing is the ideal method to protect leads from abrasion and contamination. Sharp bending is not possible with this type of leads.

Stainless steel armor leads exiting straight

E1 Style


Tubular ends folded at a right angle with Stainless-steel braids which provide strength and protect leads from abrasion. Sharp bends are possible with this type of lead.

European plugs

E2 Style


Tubular ends exiting straight from the edge of the strip heater with stainless-steel braids. To prevent failures, leads should never be pulled or used as transportation handles.

Terminal boxes with stainless steel or armored leads

G1 Style


NEMA-1 enclosures provide protection against exposed electrical wiring and terminals. Enclosure dimensions can change with heater size.

Installation tips

  • Aluminum Strip Heaters are relatively less vulnerable than Mica Strip Heaters to forming hot-spots; nevertheless, the surfaces being heated must be clean, perfectly flat and without any holes or cavities.
  • Whenever possible, hold-down clamps should be used to firmly secure an Aluminum Strip Heater onto a surface. Otherwise, heaters with mounting slots (optional) should be selected in order to be able to use fasteners.
  • To avoid detachment (arching) of an Aluminum Strip Heater from the heated surface due to thermal expansion, the mounting screws on the terminal side should be tightened firmly, while the screws on the opposite end should be tightened to secure the heater on the surface but allow for linear expansion.
  • Although they are contamination proof (apart from their terminations), the accumulation of dirt, oils or plastics on Aluminum Strip Heaters are fire hazards and should be prevented.
