9. A method of producing a steam autoclave process chamber consisting of:
making of an open cuboid metal tank with walls in the form of a single casting of any desired shape under a known casting method
drilling holes in the casting
mechanical machining of the casting
fitting the casting with chamber accessories
placing, before the casting is initiated, at least one pipe heater (4) in the casting mould so that the at least one pipe heater (4) is found inside a cast wall of the tank, and that ends (10) of the heater pipes extend outside the casting mould, and
filling the mould with molten metal in which the pipe heater (4) gets sunk inside each of two larger parallel side walls (1), wherein
each of the pipe heaters (4) is wavy in shape, with a number of straight sections running parallel to one pair of edges of larger side walls (1), where straight sections are interconnected with arches, wherein
on both sides of heating elements of the at least one heater (4) there are insulation plates located which contact directly radiators made of aluminium, wherein
on a back wall (3) connection stub pipes (6) are extending outside the tank, wherein
the larger side walls (1) have ribs (11) shaped on their external sides, where the ribs run perpendicular to the straight sections of the pipe heater (4), wherein
on a back wall (3) there is one mounting opening (8) made and additional mounting protrusions (7), wherein on each of the larger side walls (1) there are additional positioning protrusions (13) located, and wherein
there are extending tabs (5) shaped on smaller side walls (2).
