MCH (Cermet Heater) heating element is manufactured by the following process. First, a high-melting-point metal (tungsten or molybdenum-manganese) thick film circuit is printed on the AL2O3 ceramic slurry by screen printing, and the design of the printed pattern and the circuit should be consistent. The ceramic green sheets printed with the metal circuits and the ceramic tubes were then pressed together in a hydraulic press and sintered in a high temperature hydrogen furnace at 1650 ° C for 22 hours.

Finally, nickel leads are brazed at 1000 °C onto the metal end and put on with Teflon sleeve, which make it a MCH heating element. It is a new type of high efficient heating elements, which can save more than 20%-30% power effect compare to PTC ceramic heaters.

The temperature can reach 200 °C in seconds and 500 °C in 30 seconds, the max and steady temperature can be up to 600-800 °C which depends on the heat sink. Ceramic heater pass 1 minutes 'ON', 1 minutes 'OFF' for 20000 cycles life test at around 280 °C.

    Perfect for scientific research in lab environment due to its small size, high power density, high temperature and excellent insulation.

Our alumina ceramic heaters have many excellent features that do not exist in the sheath heaters:

1. High power density, excellent thermal efficiency

2. Rapid heating, non-hotspot temperature distribution

3. High temperature, small size, light weight

4. Excellent insulation (the leakage current is<0.5 mA under voltage 4500V/1S testing with no breakdown)

5. High reliability, stable resistance, no electric noise

6. Good chemical resistance

7. full compliance with EU RoHS (no lead, cadmium, mercury, hexavalent chromium, PCBS, and other harmful substances)

8.Surface is not charged, safe and reliable.

The MCH is widely used in all kinds of applications nowadays, such as: intelligent bidet seat, electric water heater, medical machine, dryer, electric heating splint, electric iron, vacuum flask, electric cooker, electric bonder, capper, UTR cylinder condensation-proofer, IR physiotherapy equipment, intravenous injection heating, quick food heating, mini thermostatic bath for special crystal parts, automatic exhaust oxidation sensors, industrial equipment heater, and small heating appliance, etc. To know more, please contact me:

========================== Questions and Answers ========================

1. What is the operating voltage for a heater?

    Approximately, square root of P*R, where P is the power you need and R is the resistance of the heater.

A heater only has a fixed resistance R at room temperature. Generally, there is no fixed operating voltage for a heater and it all depends on the heat transfer application (which determines the power P you need). Then roughly, the operating voltage V for your application would be the square root of P*R. The thing matters the most to a heater is the highest temperature it can endure. As long as the temperature at the hottest location (usually the geometry center of the internal winding coil in heater) is below that highest endurable temperature, it can output any power you need if you have a proper power supply and heat sink (thermal load). The above statement assumes a steady-state situation. For transient case (e.g. temperature rising process), large voltage jump should be avoided in case the large thermal shock or current shock. There are also other uncommon limits/properties which need to be considered in special situation. Please see physical properties next to the main product image.

2. How to determine the power I need to heat my objects to a certain temperature (e.g. 200 Celsius)?

    Estimate the heat loss from your objects at a certain temperature (e.g. 200 Celsius) to environment or supporting frame through thermal radiation, conduction and convection. Please educate yourself by google if you are not familiar with these terms. You can definitely design your system to manipulate the three types of heat transfer to suit your need (e.g. reducing heat loss by using thermal insulation or thermal shield or polished surface, making temperature more uniform by using high thermal conductivity substrate). The power you need should be at least 30% over of your heat loss estimation for safety (1.3X).
