Muffle Furnace HSHD-YHSX2

1. Overview

The new generation box-type resistance furnace incorporates the company’s years of design and manufacturing experience, integrates advanced foreign technology, and features multiple design patents. It is specially designed for laboratory use in industrial and mining enterprises, universities, and research institutions for chemical element analysis and high-temperature heat treatment processes such as quenching, annealing, and tempering of small steel components. It can also be used for high-temperature heating applications including sintering, dissolution, and analysis of metals, graphite, and ceramics.

2. Feature

1. Unique door design ensures safe and easy opening while preventing high-temperature gas from escaping the chamber.
2. Microcomputer PID controller offers simple operation with precise, reliable, and safe control.
3. Door liner and panel are made of stainless steel, providing corrosion resistance and maintaining shape under high temperatures.
4. Lightweight chamber ensures long-lasting durability (refractory brick chamber or ceramic fiber chamber available).
5. Excellent door seal minimizes heat loss and improves temperature uniformity within the chamber.
6. Optional 30-segment programmable controller allows setting ramp or soak for each segment, offering programmed cycles of temperature, time, and heating power.
7. Optional high-quality stainless steel housing provides corrosion resistance.
8. Optional RS485/232 communication interface, USB port, or embedded printer (choose one) available upon request.Safety Features
   1. The furnace door safety switch automatically cuts off the heating power when the door is opened during operation, ensuring operator safety.
   2. Multiple safety protections such as overcurrent, overvoltage, and overtemperature ensure safe operation of the furnace.
   3. Ceramic fiber board is used as thermal insulation material, offering excellent insulation performance and low outer casing surface temperature.
   4. Short-circuit and open-circuit protection for the thermocouple.
