Double spiral type SIC lab heating element manufactured by Yuhao

YUHAO Brand  SiC heating element has many types,such as GD type,GC,U,W,SG,SD type.The SiC heating elements have hot and cold zones.Its main material is selected super quality green silicon carbide.So it can be used in various high temperature electric furnaces and other electric heating devices.

Double Spiral Silicon Carbide Heating Elements are made from very dense silicon carbide, featuring a return spiral groove allowing connection at one end. The resistance and allowable surface loadings of the Double Spiral Shape Type are substantially higher than other silicon carbide elements, consequently operating voltages are higher and current draw lower. This feature can lead to significant savings in both control equipment and wiring. Double Spiral Shape elements are energy conserving, convenient and easy to install due to the same-end terminal structure.

When you place an order of the Double Spiral SiC Heating Element, please give following information:

OD(mm): Outer Diameter
HZ(mm): Hot Zone length

CZ(mm): Cold Zone length
OL(mm): Overall Length

If you have the special requirement for the resistance, please tell us!

The Advantages of Silicon Carbide Elements from YUHAO:

--No fuel availability or storage problems
--No noxious fuel exhaust to be ducted away
--High strength and excellent shock resistance
--Economical, dependable, high-quality, excellent after-sale service
--One of the highest hot: cold ratios in the industry
--Efficiently handle a wide range of products and atmospheres without any protection atmosphere

Notes for using and installing the heater:

1. Heater should be protected against damp during storing or installing to ensure the performance of the heater.

2. In order to be sure of well-distributed lod of each and groups, heater should be divided before assembling. The tolerance of the resistance of each one cannot exceed by 10% each other.

3. Heater is hard and brittle, please be careful when assem bling and maintaining so as to avoid damage.

4. When operating the electric furnace at the beginning, the voltage should be increased slowly and cannot be fully loaded at once. Otherwise the larger current will be resulted in the damage of heater.

5. When heater is damaged and need to be changed, the resistance of new ne should follow the increasing resistance. If many are damaged or resistance increased too much, heater should be changed.

6. Silicon Carbide (SIC) heating elements is a non-metal electric heating element made from SiC as its main raw materials. It has some specific properties, such as low expansion coefficient, little deformation, stable chemical property, long service life, easy installation and maintenance, etc.
7. Usage: Silicon Carbide (SIC) heating elements can usually make use for furnace which temperature from 600-1600. It can be directly used in an air atmosphere, without any protection atmosphere. It is extensively used in the fields of metallurgy, ceramics, glass, machinery, analysis test, semiconductor, science & research and so on.
