Finned Air Heaters

 

FINNED AIR HEATERS


APPLICATION
For air heating installations requiring electric heat such as forced air duct heating, recirculating drying ovens, packaged air conditioning equipment, convecto heaters, load testing equipment, as well as any other air heating application where the sheath temperature does not exceed 400 ° C.

CONSTRUCTION
Our elements are manufactured in the following materials as standard:
Stainless steel element with stainless steel fin.
Other sheaths and fin materials may be used, provided these are available and suitable for manufacturing finned heating elements.
To ensure long life it is important to select the correct materials and KW rating required for each application.
Please consult our engineering office when considering the design of any new requirement.

BENDING

Our finned heating elements can be bent in any shape provided the final formation is mechanically pratical. There are, however, limiting tolerances as well as maximum and minimum bending radii which must be respected. Since over bending can cause elements to break or crack, we recommend that all elements are bent in our workshops. Tooling already exist for bending the more common customes' requirements, but in certain cases, particularly for multibent elements, it is for elements to have close tolerances after being bent, our sales department will advise on special tooling costs.

MOUNTING
Our finned heating elements may be fitted with any terminals or maounting arrangements. Customers fitting elements in their own equipment should ensure that they are well spaced across the duct face and if mounted in rows are staggered. Care should also be taken to ensure adequate clearance exists between the element and the air duct wall. The layout of the elements can materially effect resistance to airflow and pressure drop through the system. Our engineering department are available to advise customers.

FINNED AIR HEATERS
Air Heating Elements

ILF Finned Air Elements come complete with standard stake-on bushes.
Mounting bushes are fixed to each end of U, W or Triple U form elements, While Straight elements have one fixed and one floating bush.

31 Kw per Sq.Metre Series, Max. Sheath Temp 400°C at 20°C Ambient.
Nominal Sheath Diameter 8.2 mm, Nominal Fin Diameter 26 mm.
