Fast heat cartridge heater

Description

Cartridge heaters can be considered as the "heating elements" or "component heaters" that are used to place the heating roles in the limited room of many different applications and equipment. They are made of crimped-on or swaged-in lead construction that consists in a high-grade nickel chromium resistance wire wound around a high-quality MgO core to ensure the high quality and long service life time.

We can make the cartridge heaters based on your temperature requirements, the high temperature can be up to 760℃.

We can make wide range of diameters, the minimum down to 3mm and maximum diameter up to 35mm.Most popular sheath material is SUS304, SUS316 and Incoloy840. So our cartridge are durable and reliable.We keep the length and diameter precise in order to perfectly fit on your application

Production of cartridge heater must consider the diameter of the tube and template aperture, the diameter of the electric heating tube is too large, resulting in the electric heating tube can not be loaded into the hole, and consider the expansion factor of the tube after heating, for late maintenance inconvenience; In addition, the pipe diameter should not be too small, and the vacancy between the hole wall and too large should not be reserved, or it will affect the heat transfer effect and service life of the electric heating tube. More to consider the size of the power of the single head electric heating tube and the size of the voltage.

The heating speed is one of cartridge heater's important performance indicators, which determines how much time it can reach the predetermined heating temperature under a specific working environment.

The heating speed is closely related to its power density. The greater the power density, the more heat generated per unit time, and the faster the heating speed. Therefore, when designing the fast heat cartridge heater, it is usually considered to increase its power density to improve the heating speed. However, excessive power density can also lead to overheating or damage to the heating element, so it needs to be optimized under the premise of ensuring safety.The heating speed is also affected by the surface area of the cartridge heater. The larger the surface area, the greater the heat exchange area with the surrounding environment, and the faster the heat transfer rate. Therefore, the design of a reasonable shape and size to increase its surface area is an effective way to improve the heating speed.

The working environment is also an important factor affecting the heating speed of the fast heat cartridge heater. Environmental temperature, fluid flow speed and other factors will affect the heat transfer speed. For example, in the case of lower ambient temperatures, the heating element needs to consume more energy to overcome the impact of the ambient temperature, so the heating rate may be reduced. The faster the fluid flows, the faster the heat is taken away, which also affects the heating rate.

Although it has a faster heating speed, it still needs to pay attention to its safety and stability in actual use. Excessive heating speed may lead to overheating or damage , and even cause safety accidents. Therefore, when using it, its working conditions should be strictly controlled to ensure that it operates within a safe range.

Structure

Nickel-chromium resistance wire is precisely wound on high purity magnesium oxide cores and filler materials swaged inside stainless steel sheath. The compacted design gives maximum heat transfer. Nickel-chromium resistance wire gives maximum heater life. High-temperature lead wires or nickel pins are swaged into the heater. End discs are welded to prevent contamination.
