Important Autoclave Differences

TEC Autoclaves Competitors Autoclaves  
Computer Control Touch screen
TEC is the only supplier who offers a PLC Touch Screen as part of all ACCS computer control upgrades and on all new Autoclave Systems.
Dual Control to prevent part load loss
ACCS offers PC and PLC control of your Autoclave system. This process means that if the computer fails during your critical part run the Autoclave will continue to monitor and record all events in order to save your expensive load.
Full radial annulus
TEC engineers design each and every fan motor around the part criteria to create a uniform internal airflow of approximately 200 feet per minute. The flow modeling performed by our engineering team has determined that a system with a full radial annulus is the only way to ensure that the system performs to the required specifications with room to spare. TEC has found this design provides superior airflow and the only proven method which achieves uniform temperatures throughout the Autoclave.
Autoclave Doors that won't deform
All TEC Door Systems are designed to prevent deformation as opposed to other suppliers who simply design around the allowable stresses, thus reducing the effective useful life in a real time production application. TEC doors provide long term reliability and performance in a heavy production environment.
Zero Maintenance Door Hinges
TEC's standard oversized hinge assemblies incorporate Oilite bushings for zero maintenance and exceptional performance for the life of the Autoclave.

Improved Door Closure and Wedges
All TEC door closure and wedges are oversized to reduce stress levels and ensure long-life over many production cycles.
Indirect Gas Fired Combustion Systems
Standard with all TEC gas Autoclaves. TEC uses only 321SS materials for our custom engineered heating coils which includes 20% excess capacity and are manufactured by TEC to last decades without the need of removing for servicing.
Vacuum Pass-Throughs
TEC's standard ACCS for our computer control systems utilizes Allen Bradley (AB) brand products. Not only are AB products superior in this application, spare parts are readily available all over the world.
Interior anti-corrosion aluminized steel sheet metal
Sheet metal is installed with thermal expansion joints to allow material to expand and contract during heating and cooling. This prevents buckling and gaps in the internal vessel sheet metal walls.
Rockwool and / or Kaowool insulation
This insulation will keep the shell temperature at an average of 140ºF or lower during normal operation.
Several layers of safety into every door
TEC’s door and closure design exceed all ASME requirements for a comfortable margin of safety not found anywhere else.
Several layers of safety into every bridge system
TEC’s bridge systems are designed to prevent over extension for maximum safety. TEC includes check valves to prevent draw bridge from falling in the event of a failure.
Autoclave cooling coil and fan motor cooling coil are full floating designs
This design allows for thermal expansion. Cooling coil is made of carbon steel as the standard design which is the preferred material for this application that offers superior cooling properties as well as longer life with proper water treatment. Standard on all TEC Autoclaves are thermocouple sensors to prevent overheating and damage to the fan motor.
Cooling valve system
TEC's standard cooling system includes a main cooling valve, trim cooling and coil drain valves. This multiple valve design provides optimum cooling performance and protect the system from unnecessary stress that can lead to premature failures.
Independent over temperature protection system
All TEC Autoclave have an independent over temperature protection system. Type “J” thermocouples jacks are installed in the interior for part feedback.
