The entire system shall be warranted as follows: Sterilizer Vessel and Doors..................... 15 years Sterilizer Control System........................ 1 year Sterilizer Piping, Valves, Etc................... 1 year Labor..................................................... 1 Year EFFLUENT CLEANSING SYSTEM (Discharge) The sterilizer shall be fitted with a steam heated, Effluent Cleansing System. This component is a combination of devices, which form a system to sterilize the discharged waste water, air and condensate, typically found in a sterilizer which is utilized for highly contaminated products. During a typical steam sterilization cycle, there is a certain amount of condensate formed, which is discharged to the drain area, which may contain highly contaminated material. Prior to the attainment of sterilizing temperature within the chamber of the sterilizer, this substance needs to be sterilized, and then cooled, prior to final discharge into the general waste system of the building. As steam under pressure enters the chamber of a sterilizer, it is a normal function for the steam to push out any remaining trapped air, and condensate towards the chamber drain, which is designed to accept this product. As the steam passes over, around, and through potentially contaminated product, the sterilizer drain design allows the flow of air, steam and condensate to flow into a special steam heated heat exchanger which raises the temperature of the discharged products (effluent) to a pre-set temperature of approximately 300 F. Then, the same discharged products flow into a second heat exchanger which is cooled by flowing cold water, to reduce the temperature to approximately 140 F. The remaining mix of cold water and the chamber discharged product, now may pass safely into the general waste system of the building. This design is typically an ongoing process, whenever the sterilizer is in cycle, as the sterilizer never knows if the chamber waste is contaminated or not. Additionally, the system will be fitted with two (2) temperature controllers and two (2) automatic motorized to open, spring to close, ball valves, which will close and isolate the system if the discharge temperature falls below the specified temperature of approximately 300 F. The two temperature controllers and two spring loaded ball valves are utilized as a redundant system to insure containment of the chamber discharge. Once this occurs, the sterilizer will pause and not allow any additional steam to enter the chamber. The automatic chamber drain discharge valves will close and isolate the chamber discharge, until the chamber discharge temperature is again above the set point (nominally 300 F). Once the system is in a paused mode, during the sterilization phase, the chamber temperature will begin to decline. For units equipped with "microprocessor control systems", if this situation remains for a preset time period, the sterilizer control system will alarm, "Low Temperature", to alert the operator of a potential steam issue. On the other hand, if the discharge temperature is below the set point only momentarily, the operator will not be alerted, and the system will continue its cycle once the discharge temperature is again stable. The system also includes manually operated ball valves on the chamber drain piping, steam to chamber piping, air-in piping, and the discharge to drain piping for isolation of the system for component repair and/ or replacement. This helps to insure that the persons performing repairs have the opportunity to completely secure the chamber, if required. One full year of Preventative Maintenance and Repair Service shall be provided at completion of the Standard One Year Parts and Labor Warranty Period. Entry into the installation site, placement in the pit, and final utility connections shall be the responsibility of the sterilizer manufacturer. All utilities (Clean Steam, Facility Steam, Cold Water, Electricity, Compressed Air, and Drains) will be provided within 3' of the installation site (By Others) Unique Features: that are not available from other vendors include but are not limited to: "The entire chamber of the unit is manufactured in the "United States of America" (USA) from thick Type 316L Stainless Steel, highly polished to a mirror finish "The horizontal sliding doors use a pneumatic air cylinder to move the door plates into the open or closed positions. No cables or belts are used that could stretch or fray over time. "The sterilizer is piped with all "T304 Stainless Steel Sanitary Clamp", "rigid brass" or "black" threaded pipe and fittings. No copper solder joints are used with the main pressure piping system that could cause future leaks or cracks in the piping. "Buxton utilizes an industrial grade Allen-Bradley SLC500 microprocessor control system which is known worldwide for its dependability and solid construction. This includes a 6" PanelView Plus 600 Color Touch Screen on both the load and unload sides of the sterilizer. The control includes all 10 Amp, plug in relay outputs with manual overrides for long life and trouble free operation. "Buxton's unique automatic chamber exhaust system will relieve the chamber of all steam if the power is interrupted, or of the operator aborts a cycle. The system will vent the chamber, based upon the specific cycle previously chosen. "The interior chamber is sloped to the drain for complete drainage of moisture from the chamber floor. "The 10.0 HP Water Sealed Vacuum Pump is manufactured with a stainless steel pump housing and 316L impeller, close coupled to a 10 HP tri-wound, heavy duty, high efficiency, RoHS Compliant motor. "The vacuum system and related piping includes stainless steel, sanitary clamp type piping and valves for ease of service and repair. One and one-half inch stainless steel welded sanitary chamber penetrations are used for the validation ports on the chamber. They are tilted into the chamber to prevent any water or condensate to form which could compromise the validation process. "The Buxton Bio-Seal assembly is manufactured for installation from one side of the sterilizer, with the use of stainless steel welded studs spaced approximately 3" apart for a secure and leak free installation.
