Gruenberg Ships Two Truck-In Sterilizers for the Medical Industry
Gruenberg, a leading industrial oven and sterilizer manufacturer, is pleased to announce the shipment of two (2) Truck-In Sterilizers for the Medical Industry.
The truck-in sterilizers have a maximum temperature rating of 232°C and interior dimensions of 30” W x 59” D x 79” H. The two units will be placed side by side at the customer’s facility so one unit is designed with a right-hand hinged door and right-side mounted control console, and the other unit with a left-hand hinged door and left-side mounted control console.
The sterilizers utilize electro-mechanical door locks to prevent the door from being opened when the sterilizer is processing, protecting product loads from being damaged due to accidental disruptions in the process occurring when someone opens the door. These sterilizers also feature uninterrupted power supply (UPS) systems which will supply power to the control circuits for a brief period in the event of a power loss. This allows the sterilizer to potentially restart and also allows the temperature controller to continue to record temperature data to help identify quality issues with that batch of product.
The truck-in sterilizers are designed with high-volume, horizontal airflow systems to ensure uniform heat distribution throughout the sterilizer chambers and optimize efficiency. The circulation motors include variable frequency drives and soft starts. The air intake/exhaust systems utilize fiberglass media filters to filter the air entering and leaving the chamber. The system provides pressurized air, ventilation and cooling with a pressure intake blower and air intake blower that uses variable frequency drives for speed adjustments during heating and cooling cycles.
The control panels are UL-certified, and each has a communications module with a USB port, an Ethernet port, and a 120V outlet. The temperature for each sterilizer is controlled by an Allen Bradley CompactLogix PLC with Ethernet capabilities, HMI technology, a user-friendly touch screen, and the ability to store up to 10 recipe profiles. Temperature uniformity within the chamber of +/- 3°C at 121°C and 163°C was documented with a 12-point profile test after a 60-minute soak.
“The electro-mechanical door locks on these Gruenberg sterilizers are a protective measure to prevent accidental disruptions in the process from someone opening a door. If the door is opened mid-process, the product load would be damaged and result in lost product and production time.”
– Mike Schneck, Gruenberg Product Manager
