Product Overview
Type W elements use three or more connected legs to distribute heat across a wider furnace zone while keeping terminals on the accessible side. Junction geometry and resistance balance between legs are critical to uniform operation.
Applications
Common enquiries involve float-glass systems, wide ceramic kilns and industrial furnaces that require multi-leg coverage or replacement of a discontinued assembly.
Selection Data
Send the number of legs, spacing, individual hot lengths, terminal arrangement, total resistance and circuit diagram. Support locations and expansion allowance should be reviewed before dimensions are frozen.
Installation And Service Considerations
Element spacing, terminal ventilation, support design and expansion clearance affect operating stability. New and aged elements may have different electrical behaviour, so circuit grouping and transformer adjustment should be reviewed during maintenance. Avoid mechanical stress during unpacking and installation, and keep conductive contamination away from terminals and insulation.
Replacement Reference
A W-type replacement for systems previously using Kanthal Globar, I2R or Tokai EREMA components must be reviewed as an engineered assembly. No universal drop-in compatibility is claimed.
Quotation Checklist
For a faster technical response, include the furnace manufacturer and model when known, photographs of the complete element and both terminals, a sketch with dimensions, the required quantity and the reason for replacement. If an old sample is available, retain it until the proposed dimensions and resistance have been agreed.
Technical Review Before Production
A heating element should not be selected from appearance alone. Send the existing drawing, readable markings, overall and sectional dimensions, nominal resistance, voltage, power and quantity. Also identify the furnace temperature, atmosphere, cycle frequency and mounting orientation. These details allow the proposed geometry to be checked before a quotation or production drawing is issued.
Supply Scope And Important Notice
Type W SiC Heating Elements can be supplied in standard or customer-specific dimensions after technical confirmation. The final proposal applies only to the reviewed drawing and operating conditions. Brand and furnace-maker names, when mentioned, identify the customer’s existing equipment; they do not imply authorization, endorsement or a universal drop-in replacement.
