High Temperature Steamers

Designed and built according to the European and American quality codes POZZI BR
autoclaves have contributed in the past 60 years to the refinement of textile
steaming technology.

A series of subsequent developments has brought todays shape.

The construction gives the choice of one or two doors both with either automatic
clamp locking or vertical sliding mechanism.

The standard working pressure allows working up to 140°C, if requested the
machines can be supplied with higher pressure and temperature characteristics.

The door locking mechanism is designed in such a way to guarantee maximum
security.

In the standard unit, vacuum generation is obtained through a liquid ring pump
with a pre-condensing stage.

Optionally the machine can be supplied with steam ejector pumps to reach higher
vacuum levels.

With all options, gasket design of the machine is tight to a few Torr.

Efficient removal of air from inside the package is one of the basic requirement
to guarantee total and uniform steam action.

Without effective air removal every residue remaining trapped inside the package
behaves as an effective impenetrable boundary to the diffusion of steam thus
impeding the uniform rise of temperature.

On the other hand POZZI autoclaves can treat with perfect uniformity packages of
very large dimensions using "air-wash" vacuum techniques.

Evenness of the action and care not to generate thermal shocks lend to the
control shrinkage of stretch yarn avoiding the uncontrolled deformation of
tubes.

Using saturated steam, the temperature of all the packages is reached in the
most uniform way: the coldest package receives a higher quantity of steam in
such a way as to level its temperature with the rest of the load.

The need for steam ventilation inside the autoclave is thus removed.

A fully programmable microprocessor control governs the insertion of all
functions ,including intermediate vacuum operations and the process control of
the temperature gradient.

To reduce the energy consumption and increase the uniformity of treatment the RA
option can be fitted to the machine.

All machines can be networked to the PDLX control data logger software to
provide ISO level standard of quality control
