Laboratory Electric Oven (Perfect System up to 3500C & 4500C): SMI 121



Jindal ovens are sturdy, with double-walled construction. The inner chamber is made of an ALUMINUM or STAINLESS STEEL sheet. The outer chamber is made of mild steel sheet, duly powder coated.

The gap between the walls is filled up with special-grade glass wool for proper insulation to avoid heat losses. The inner chamber has ribs for placing the shelves at convenient levels. Supplied with 2 or 3 removable shelves. The oven door is mounted on heavy hinges with a handle. The door is duly insulated.


Heating elements are made of high-quality nichrome wire and are put inside beads and placed at the bottom and in both side ribs for a uniform temperature all over the work space. Other types of heaters, like jacket heaters, rod heaters, and sheet heaters, are also available for specific requirements.

Temperature Control:

The temperature range of the hot air oven shall be from 500 C to 3500 C/4500 C, controlled by a digital PID controller along with an air circulation system for best accuracy.

Forced Air Circulation:

In this system, there is one path for circulating hot air between the inner chamber and the insulation with the help of an air duct. Forced air moved by the motorized blower is called the Perfect System.” It results in a minimum temperature variation at any point in the working space.

Control Panel:

consisting of a switch to turn on or off the power, a rotary switch to select high or low rates of heating, a thermostat control knob, and indicators for mains and thermostats. Supplied with a cord and plug.
Designed to operate on a 220 volt, single-phase, 50 Hz AC supply. (Please specify any customization.)
