Transfer Cabinet
The aseptic transfer cabinet is used for biological
dirt removal treatment on the exterior surface of materials, so as to prevent
materials from entering class A/B key regions from no-class regions/low-class
clean regions. Taking advantage of hydrogen peroxide in the gas state at normal
temperature having better ability to kill microorganisms than that in the
liquid state, the saturated hydrogen peroxide vapor forms slight cold
condensation coating on the material surface that releases free hydroxyl
groups, which is used to attack microbial cell components including lipids,
proteins and DNA so as to meet the requirements of complete inactivation of
microorganisms. The machine can be used for various clean and dry objects that
need to be transmitted during aseptic production, for example, external packaging
of packing materials, instruments, vessels, packing of raw and auxiliary
materials, fittings, environmental monitoring equipment, and etc.
◆ The aseptic transfer cabinet adopts VHP as the
biological decontaminating agent, which can effectively kill fungal and
bacterial propagules and spores, viruses, mycoplasma and other microbes. VHP
sterilization is a decontaminating process at low temperature and normal
pressure, featured by good material compatibility, broad spectrum, high
efficiency and environment-friendly.
◆ The SIEMENS PLC automatically controls each
operating phase of the aseptic transfer cabinet. Through the simple operation
interface, circulation parameters can be set and obtained. The system runs
precisely, stably and reliably.
◆ A double-door structure is adopted for feeding
and discharging. It is provided with functions of pneumatic sealing, pneumatic
locking and double-door interlocking under the work status.
◆ In a whole circulation cycle, materials are
always under the 100-grade (grade A) environment to prevent materials from
being polluted. The clean environment in the cabinet also prevents the grade
A/B clean area from being polluted after the cabinet door is opened.
◆ The aseptic transfer cabinet is provided with the
cart type material support and the guide rail system inside, which make
material feeding and discharging to be more convenient. The system carries out
real-time monitoring of the temperature, humidity and pressure in the cabinet,
provided with friendly man-machine interaction function. The optional
inspection ports for VHP concentration, dust particles and airborne microbes
would make operation more convenient.
◆ It is provided with the built-in VHP generation
system. The circulation loop technology optimizes the sterilizing time. The
sterilization process can be displayed by diagrams, and the online display of
key parameters is carried out in real time. The data for each circulation cycle
is saved, so that the data records can be traced while the output of data
parameters and diagrams can be obtained.
◆ It has the independent ventilation residue
removing unit, which includes the fan, valve and exhaust pipe, which can
quickly displace VHP gas inside the cabinet and prevent it from entering the
HVAC system. The residues of VHP gas will not exceed the level required in the
occupational health and safety management system while the concentration of
residual VHP≤1ppm.
