HYDOGEN EMBRITTLEMENT RELEF OVEN

·Features

Two chambers can be operated separately at the same time.( Two chamber effects!)

1. By using Digital P.I.D temperature controllers provides excellent temperature precision, and can be freely set temperature raising and temperature maintenance.

2. The PID Controller is a multifunctional temperature controller with built-in precise temperature control, Timer, Alarm, Auto Tuning, etc. and display the set temperature (SV), present temperature (PV) at the same time.

3. Auto Tuning : It is an operation function that calculates the PID integer required for optimal control by measuring the thermal characteristics and thermal response rate of various controlled objects on its own, and sets the value produce fast response and stability.

4. The temperature distribution is uniform and the drying time is fast as the air inside the chamber is forced to circulate by the sirocco fan.

5. Perfect double insulation treatment prevents internal heat from being transferred to the external.
Offering even temperature distribution, perfect and safe design.

6. The height of the shelf can be adjusted and additional shelves can be ordered.

7. Time range selectable(4 digits) → 99Hr59Min, 99Min59Sec, 99Day99Hr

8. Automatically return to set mode in case of power failure

※About HYDOGEN EMBRITTLEMENT RELEF OVEN?

Normally in electroplating, the hydrogen generation of the cathode causes hydrogen to penetrate on the materials. In the case of galvanization, a certain amount of time passing after hydrogen penetrates into the inside of the iron. If iron contains hydrogen, it may lose ductility and become vulnerable, so iron may break, shattar, or crack to exist. Two chambers can be operated separately at the same time.( Two chamber effects!) Hydrogen Embrittlement Relief Oven is equipment that produce as perfect and superior products by removing these hydrogen from materials or components

A material or component that is put into a 'Hydrogen Embrittlement Relief Oven’ to remove hydrogen.
