A High Range of Temperatures for a Wide Range of Applications

As an industrial furnace manufacture, we understand that the number of applications for industrial (and laboratory) furnaces is large. To meet the many needs of our customers everywhere, we've manufactured our end loading tube furnaces with versatility in mind. That means a wide range of temperatures, programmable temperature controls, and other helpful features.

Tube furnaces from Oxy-Gon are rated for a maximum operating temperature of 2500°C (4532°F) and will operate in vacuum, inert atmospheres, or Nitrogen. Common applications for the end loading tube furnace include:

  • Annealing
  • Brazing
  • Melting
  • Sintering
  • Heat Treating
The basic tube furnace system includes the following components:
  • Furnace Assembly
  • Power Supply
  • Heat Zone
  • Evacuation System
  • Inert Gas System

Ceramic Muffle Tube Kits are available for oxidizing/corrosive atmospheres. Vertical mount is also available.

Furnace Assembly

The chamber of this tube furnace is double walled, 304L stainless steel and is electropolished to attain the highest vacuum quality. The power feed throughs, covers, and access lid are all nickel plated copper construction. Ports are incorporated in the chamber and/or access lid for a sight window, thermocouples, or an optical pyrometer.

Heat Zone

The element and insulation are high grade graphite. Heat Zone sized range from 2" ID to 6" ID x up to 48" long with a muffle tube. Without the muffle tube, the size ranges from 2" ID to 12" ID x up to 48" long. Other sizes are available upon request.

Power Supply

Power supplies can be supplied with any of the following characteristics: Single (1) or three (3) phase, 208, 380, or 480 volts, and 50 or 60 hertz. A typical power supply incorporates the following components: Stepdown tranformer, SCR power controller, circuit breaker, contactor, pushbuttons, and indicator lights. All components are wired and housed in a free standing cabinet. Temperature Control

Depending on the customer's requirements, OXY-GON INDUSTRIES, INC. can incorporate as a part of the furnace system the programmer/controllers, recorders, and temperature control devices (i.e. thermocouple, optical pyrometer, or power transducer).

Pumping System

Manual through fully automatic (PLC control) pumping systems can be provided for the range of 10-20 Millitorr (rough vacuum with mechanical pump) through 10 -5 Torr (high vacuum with diffusion and mechanical pumps). Our typical standard system is automatic and consists of a diffusion or turbomolecular high vacuum pump, mechanical pump, the necessary valving, and a vacuum gauge controller. The system will consistently operate in the 10-5/ 10-6 Torr range.

Inert Gas/Nitrogen System

To allow operation using inert gases or Nitrogen, a kit which includes inlet/outlet valves and a pressure/ vacuum gauge is supplied as well as a glovebox interface kit.
