Oven Construction:

Outside:

Oven to be constructed of heavy gauge carbon steel and structural members and painted a slate gray. The face of the unit will be painted a high temperature black.

Inside:

Oven to be constructed of Stainless Steel. The chamber will be welded & sealed.

Circulation system:

A 24” Dia fan and shaft, Horizontal airflow from right to left. All pressure and return walls will be louvered for adjustability. The circulation system will be monitored by a pressure differential switch in the event of the loss of circulation air the heating system will shut down.

Heating system:

12- 2500W Incoloy sheathed heating elements will be housed in the plenum to heat the air to desired temperature.

Doors:

The unit will have one door held closed by a two or three point positive cam latching system. The unit will have an inner door seal of ceramic fiber covering a stainless mesh core. The outer gasket will be silicone bullet shape to ensure a positive seal.

Control Console:

The control panel for the oven will be on the right hand side of the chamber. The panel will house the electrical components and be NEMA 1 and UL rated.

Inert Atmosphere:

The unit will have an inert atmosphere option. The unit will be supplied with a purge and process solenoid valve, regulator, filter, gauges for incoming pressure and chamber pressure and delivery system; the chamber will be welded and sealed to ensure a positive pressure in the chamber. A relief valve will also be supplied in the event the chamber pressure exceeds the desired limit. The unit will have a purge cycle before allowing the heat to come on.

Purge flow rate of 150 SCFH

Process flow rate of 120 SCFH

Assisted Cool down:

The unit will have an air jacket around the liner. There will be an intake damper and a forced exhaust that will come on during the cool down cycle. The dampers will be motorized and close during the heating cycle and open during the cooling cycle.
