Product Overview

Type DH and DL elements are straight silicon carbide rods or tubes with a central hot zone and low-resistance cold ends. They provide a practical base geometry for many new furnaces and routine maintenance programmes.

Applications

Typical uses include ceramic kilns, glass processing, metal heat treatment, research furnaces and general industrial heating where straight wall-to-wall installation is available.

Selection Data

Quote diameter, hot-zone length, cold-end length, overall length and nominal resistance. Installation orientation, element spacing and the range of the power-control system should be checked before ordering matched groups.

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

Dimensions from a Kanthal Globar, I2R or Tokai EREMA straight element can be used for cross-reference review. The customer should retain the original equipment manual and confirm circuit grouping.

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 DH DL SiC 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.
