HRY Meltblown Fabric Heater Details
HRY Meltblown Fabric Heater
Product Materials:
Common outer tube materials include In800, In840, 304, 316L, 310S, aluminum, copper, low carbon steel, etc.
Magnesium oxide powder is selected according to different usage requirements, with high-temperature powder, medium-temperature powder, etc.
The resistance wire serves as the heating element, typically made of two materials: Ni-Cr wire and Fe-Cr-Al.
Lead terminal materials generally include two types: stainless steel and free-cutting iron.
Sealing materials include epoxy, silicone, glass, etc.
Application Range:
Suitable for heating air, oil, water, chemical media, hot press molds, melting salts, alkalis, and low-melting-point alloys, etc. It features high thermal efficiency, long service life, high mechanical strength, easy installation, safety, and reliability.
Classification by shape: Heating tubes can be classified into straight single-end heating tubes, straight double-end heating tubes, U-shaped heating tubes, W-shaped heating tubes, special-shaped heating tubes, and spiral heating tubes.

Structure
It is made by inserting electric heating wire into an outer tube (carbon steel tube, titanium tube, stainless steel tube, copper tube), filling the gaps with magnesium oxide powder that has good thermal conductivity and insulation, then shrinking the tube. After heat treatment (some tubes do not require it), it is processed into various shapes required by the user. It features simple structure and high thermal efficiency.
