Abstract
A steam autoclave process chamber in the form of an open metal tank fitted with the necessary technical means to fix the closing lid and to connect the necessary accessories characterised in that there is at least one heater (4) inside the tank walls (1,2,3), where the heater is integrally incorporated with the wall into a single inseparable element. A method of producing a steam autoclave process chamber which consists in the making of an open metal tank with walls in the form of a single casting of any desired shape under a known casting method, followed by subsequent stages which involve mechanical machining of the casting and fitting it with necessary chamber accessories.

A steam autoclave process chamber in the form of an open metal tank comprising technical means to fix a closing lid and to connect process chamber accessories, wherein there is at least one heater (4) inside tank walls (1,2,3) where the heater (4) is integrally incorporated with the wall forming a single inseparable element, 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 the heating elements of the at least one heater (4) there are insulation plates located which contact directly radiators made of aluminium, and wherein
- the each of the pipe heaters (4) is sunk in a molten metal inside each of two larger parallel side walls (1), and wherein
- ends (10) of the heater pipes extend outside the tank, while on a back wall (3) connection stub pipes (6) are extending outside the tank.
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).
