Canada "The Process Equipment People" designs,
engineers and manufactures Autoclaves for many of the process industries including
pressure treating of wood, vulcanizing of rubber on to steel rolls, vulcanizing of rubber
treads to original tire casings, curing of various composites and heat treatment of
metals. Our custom built Autoclaves can be Direct Steam Heated, Indirect Steam Heated,
Electrically Heated or Jacketed for heating using either hot water, steam or thermal
fluid. Heat circulation for Indirect Steam Heated and Electrically Heated Units is
provided by a Bell Housing Mounted Fan.
PATTERSON Autoclaves can be fabricated from Carbon Steel, Stainless Steel and other Alloy
Steels, of either solid or clad construction depending on design conditions and cost
considerations. PATTERSON Autoclaves can be built from 36" diameter up to 144"
diameter, in lengths from 72" to 80'0" and up to 100 tons.
Autoclaves are primarily in the Wood, Concrete, Tire Retreading, Composites Curing, Heat
Treatment of Metals and Plastics & Rubber Industries. More specifically they are used
in retreading of truck, bus and trailer tires, rubber coating of rollers for the printing
ink industries, pressure treating of wood, curing of concrete precast products and heat
treatment of metals i.e. nitriding.
- Designed, engineered and manufactured to individual customer's specifications for
Pressure and/or Vacuum Condition and for ambient, or elevated temperatures.
- Fabricated from Low and Standard temperature Carbon Steels, 300 & 400 series
Stainless Steels, Monels, Inconels, Incoloys, Nickels and Hastelloys.
- Construction can be of either solid or clad type.
- Direct Steam, Indirect Steam, Electrically Heated or Jacketed.
- Supplied typically with saddle supports for floor mounting.
- Unique patented Hinge Door Assembly for quick opening and closure designed in accordance
with ASME Code Section VIII Division 1, complete with power-operated Hydraulic Lock Ring Assembly
that closes securely. The Door Flanges are sealed with a Pressurised "0" Ring
for maximum temperature and pressure retention.
- Autoclave door has an integral hinge and bearing assembly for easy alignment and
- System incorporates an interlock design "Zero pressure indicator" that
promotes operator safety by ensuring that the door cannot be opened when the autoclave is

Heating Fan is running, you will see the fan turning. When the Element is heating, the display will flash in red.
This screen is
used to input the Set-Points manually.
The Temperature is set by sliding the bar to the proper
value or touching the Manual Set Point square.
A keyboard will show up and you then can enter the Set Value.
Process Value (P.V.), i.e. the Current Temperature will
show on this bar. The Set
Point Value (S.P.) is shown in the bar to the right.
The Percentage Box indicates the percentage temperature
which has been reached towards the set point.
The Heater and Fan On/Off Buttons can be used to manually turn
the heater and fan on/off.
Air Nitrogen System
screen shows the Vessel Pressure in PSI.
By pressing Air System on/off, the Air System
can be manually turned on/off.
Process Cycle Data
screen is used to start the two pre-set cycles (casting and
annealing). The 2 sets of
squares display the actual running time for each cycle.
The Cycle Start Buttons are touched
when the cycle is to be started i.e. after the product has been loaded
and the Autoclave door closed.
The Stop/Reset Button is touched only after the process
data has been downloaded on to a memory stick which occurs
automatically approximately 10 seconds after the process cycle is
