DEPYR

DEPYR are Depyrogenation Tunnels for ampoules, Small Volume Parenteral (SVP) vials and larger bottles.

Main features:

Tubular stainless steel frame with hinged doors on front side and easy removable panels on the maintenance side, to guarantee total free access to every area of the tunnel;
Filters installation from operator side, all instruments, sensors, validation ports and controls are accessible from the 2 openable sides. No need of intervention or installation on top of the machine.
Inspection glass doors on pre-heating and cooling chambers;
Fully integrated on board design for quick installation; only one exhaust duct is required; also the air extracting fan is installed on board;

Standard constructional specifications:

Expansion compensation system of the metal structure during heating with no particle generation;
Automatic pressure compensation systems with the highest overpressure into the hot zone and in cascade to cooling and infeed chamber. That guarantees a perfect process repeatability and the maximization of depyrogenating capacity.
Symmetrical air recycling (50% left and 50% right side) into the hot chamber to guarantee a very constant temperature distribution across the tunnel conveyor.
Cooling chamber realized with 100% air recycling to:
guarantee a better temperature control;
achieve a very low glass temperature at the exit of the tunnel;
do not influence the tunnel room making room balancing easier;
offer a longer life time of HEPA filters
reduce energy consumption.
Innovative Dry-Heat Sterilization with dedicated resistors and separated air-ducts to implement a double air loop, one for cold air during the normal process, one for hot air during DH cycle. That makes possible to:
start the DH cycle quickly without draining the chilled water loop;
perform a forced cooling at the end of the DH cycle;
