Spring Coil Heater (H series)
3.5×3.5 Ring-Shaped Spring Electric Heater With J Type thermocouple
3.5×3.5 Ring-Shaped Spring Electric Heater With J Type thermocouple
产品概述

Coil spring heater with cross section of 3.5*3.5mm is made of quality stainless steel, German heating wire, American high-purity magnesium oxide and strict technology, manufactured by automatic devices with independent intangible intellectual property rights. It could be used in the temperature as high as 650°C. And K, J or E type temperature control thermal couples can be built in the heater according to customers needs. Integrated thermal couples can ensure accurate temperature control.

It adopts high intensity protective tube to protect heaters outlet wire. The tube can bear temperature as high as 250°C and voltage as high as 2.5kV.

It adopts two-end intense wound form with its non-heating part in L form. It could be used in casting technique and other electric heating industries, especially as hot runner mold system to provide quality electric heating.
