1. GENERAL INFORMATION 1. 1 TECHNICAL INTRODUCTION A. J. Costa (Irmãos), Lda. steam sterilizers are designed to cover a large field of applications for hospitals and medical centers as well as pharmaceutical and biotechnological industries and research laboratories. They meet the latest features in state-of-the-art sterilization technology. A. J. Costa (Irmãos), Lda. sterilizers are available as multi-functional steam sterilizer with pre-vacuum and post-vacuum technology for healthcare facilities applications and gravity capabilities as laboratory liquids steam sterilizer. All sterilizers are...

1.2. CONSTRUCTION SPECIFICATIONS 1.2.1. Frame The sterilizer pressure vessel and components are secured to a welded structural frame. The frame is constructed in stainless steel. It is mounted on threaded leveling screws with supplemental stainless steel weight distribution footpads. The frame is mechanically rectified by a CNC precision-machine, for perfect alignment of all mounted devices. 1.2.2 Sterilizer Pressure Vessel The steam sterilizer is prepared to operate with saturated steam as sterilizing agent, condensate free, 97% to 100% steam quality and working at a temperature range from 105º...

The automatic condensing system, consisting of a stainless-steel heat exchanger, converts chamber steam to condensate and disposes condensate to waste. Cooling water flow is regulated by the waste line temperature control system to minimize water usage. On double door units the end frame bulkhead of the chamber are constructed of solid AISI 316L stainless steel and entirely welded on the pressure vessel. On single door units, back of chamber is fitted with welded, 316L stainless-steel head. The complete pressure vessel is then mechanically rectified and all mechanical dimensions are controlled...

The pressure vessel is constructed in accordance with PED 2014/68/EU and the European Standard EN 13445, for unfired pressure vessels. 1.2.3. Doors Doors are constructed of AISI 316L stainless steel and reinforced, mechanically rectified by a CNC precision-machine which provides uniform quality of inner surface and precise mechanical dimensions. Doors are insulated with Rockwool fiber insulation and covered with a finish stainless steel panel. The steam sterilizer is equipped with one or two vertical or horizontal sliding doors, depending on the model. Vertical or horizontal sliding door AJC...

Double door configurations are supplied with controls and security systems at both ends of the sterilizer to prevent the possibility of cross-contamination. As a single door steam sterilizer, equipment can be mounted as a freestanding unit with covering panel frame (OPTIONAL) or recessed on wall. The single door steam sterilizer will produce loads from and to the same area. Provisions must be taken to have clear identified circuits for load the goods to sterilize and unload sterile materials for storage and distribution. Double door steam sterilizer is mounted through a recessed wall. The two...

If a cycle fails, only the non-sterile side door can be opened and operated. After a test cycle, only the non-sterile side door can be opened and operated. A door cannot be opened at the end of the cycle if the chamber temperature is higher than the preset final temperature. Double door configurations are supplied with controls and security systems at both ends of the sterilizer to prevent the possibility of cross-contamination. 1.2.4. Insulation Superior heat loss reduction to the surrounding environment and heat conservation is achieved with rigid Rockwool fiber insulation, overlaid with AISI...

connectors to simplify sterilizer piping, and can be serviced individually. Water control valves are 24V DC operated. Safety valves are approved, stamped, and sized for the vessel design pressure. As buyer’s option the steam sterilizer can be equipped with an Automatic Self-Cleaning Drain Strainer which is commonly designed for Animal Care applications. Water is back flushed through the main drain strainer circuit. This feature does not eliminate the need to perform the cleaning of the chamber. 1.2.6. Vacuum System Rapid evacuation of chamber air and moisture is achieved with a liquid ring vacuum...

As buyer’s option the steam sterilizer can be equipped with an electrical heated built-in stainless steel AISI 316L steam generator. Depending on the option, the built-in steam generator can act as a standby unit if building steam is not available for the sterilization process or can be the main source of saturated steam for the sterilization process. If the steam sterilizer has a DUAL OPTION for steam source, the steam sterilizer is built to receive two steam supply sources, namely from the building, or from the internal built-in steam generator. There is a selector function on the user interface...

1.2.8. Control System The gauges, touchscreen and printer are mounted in the stainless-steel panel. The electronic control system and software monitors and controls all sterilizer operations and functions and are designed to operate up to 25 different factory-programed standard sterilization and test programs. The control system of the sterilizer is based on PLC technology, ensuring a highly reliable and safe operation. The computerized control unit ensures a fully automatic operation through the entire process; hence, after setting the pre-selected parameters and starting the operation, no further...

In addition to laboratory work cycles, the sterilizers AJC are also programmed with test work cycles, Bowie & Dick and vacuum cycles, along with sterilization cycles for glassware and wrapped or unwrapped instruments for immediate use, with drying phase assisted by vacuum. As optional, the sterilizer can be equipped with sterilization work cycles specially designed for animal cages. These cycles enable the operator to program different process parameters, including temperature, contact time of sterilization and drying time. The process of air exhaustion is automatically controlled and implemented...
