Product Overview

Type U molybdenum disilicide heating elements combine a thin hot zone with larger cold ends for low-voltage, high-current furnace circuits. Standard U geometry is widely used because it is easy to suspend and replace when the chamber layout is designed correctly.

Applications

Suitable projects include laboratory furnaces, technical-ceramic sintering, powder metallurgy and industrial high-temperature chambers operating in compatible atmospheres.

Selection Data

We supply 1700, 1800 and 1900 grades. Select the grade from element temperature, furnace temperature, atmosphere, cycling, supports and contamination risk; the grade number is not a guaranteed furnace temperature.

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.

Replacement Reference

For Kanthal Super, I2R Moly-D or Tokai MoSi2 replacement evaluation, provide hot-zone diameter and length, cold-end diameter and length, shank spacing, resistance and furnace model.

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.

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.

Supply Scope And Important Notice

Type U MoSi2 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.
