DRK137 Vertical High Pressure Steam Sterilization Pot

Test items: Suitable for sterilization of high temperature resistant culture medium, inoculation equipment, etc.

DRK137 vertical high-pressure steam sterilizer [standard configuration type / automatic exhaust type] (hereinafter referred to as sterilizer), this product is a non-medical equipment product, only suitable for scientific research institutions, chemical institutions and other units. This product is suitable for sterilization of high temperature resistant culture medium and inoculation equipment.

Sterilization Principle:
Using the principle of gravity displacement, the hot steam is discharged from top to bottom in the sterilizer, and the cold air is discharged from the lower exhaust hole. The discharged cold air is replaced by saturated steam, and the latent heat released by the steam is used to sterilize the items.
The sterilizer is manufactured in accordance with the relevant provisions of technical specifications such as GB/T 150-2011 “Pressure Vessels” and “TSG 21-2016 Safety Technical Supervision Regulations for Fixed Pressure Vessels”.

Technical Features:
1. The working environment temperature of the sterilizer is 5～40℃, the relative humidity is ≤85%, the atmospheric pressure is 70～106KPa, and the altitude is ≤2000 meters.
2. The sterilizer is a permanent installation device and is permanently connected to the external power supply. A circuit breaker larger than the total power of the sterilizer power supply must be installed on the building.
3. The type, size and basic parameters of the sterilizer meet the requirements of the “Regulations for the Safety Technical Supervision of Stationary Pressure Vessels”.
4. The sterilizer is of quick-opening door type, equipped with safety interlocking device, and has screen graphics, text display and warning lights.
5. The pressure indicator of the sterilizer is analog, the dial scale is from 0 to 0.4MPa, and the pressure gauge reads zero when the atmospheric pressure is 70 to 106KPa.
6. The control system of the sterilizer is controlled by a microcomputer, with water level, time, temperature control, water cut, over temperature alarm and automatic power cut functions, and low water level has double protection.
7. The sterilizer adopts digital key operation, and the display is digital.
8. The sterilizer is marked with warnings, warnings and reminders in conspicuous places to inform the operator of the importance of mastering the essentials of operation and complying with safety precautions.
9. The maximum working pressure of the sterilizer is 0.142MPa, and the noise is less than 65dB (A weighting).
10. The sterilizer has reliable grounding protection and an obvious grounding mark (see Chapter 3).
11. The sterilizer is a lower exhaust steam type, with two exhaust methods: manual exhaust and automatic exhaust with solenoid valves. ([Standard configuration type] Without automatic exhaust steam mode)
12. The sterilizer sterilizes items with steam generated by water with a boiling point of 100°C.
13. The sterilizer is equipped with a temperature test connector (for temperature test), marked with the word “TT”, and is usually sealed with a cap.
14. The sterilizer is attached with a sterilization loading basket.
15. The protection level of the sterilizer is Class I, the pollution environment is Class 2, the overvoltage category is Class II, and the operating conditions: continuous operation.

Maintenance:
1. Before starting the machine every day, check whether the electrical components of the sterilizer are normal, whether the mechanical structure is damaged, whether the safety interlocking device is abnormal, etc., and everything is normal before it can be powered on.
2. At the end of the sterilization every day, the lock power button on the front door of the sterilizer should be turned off, the power circuit breaker on the building should be disconnected, and the water source shut-off valve should be closed. The sterilizer should be kept clean.
3. The accumulated water in the sterilizer should be removed every day to prevent the accumulated scale from affecting the normal heating of the electric heating tube and affecting the steam quality, and at the same time affecting the sterilization effect.
4. As the sterilizer is used for a long time, it will produce scale and sediment. The water level device and the cylinder body should be cleaned regularly to remove the attached scale.
5. The sealing ring is relatively fragile to prevent cuts from sharp tools. With the long-term steaming at high temperature and high pressure, it will gradually age. It should be checked frequently and replaced in time if damaged.
6. The sterilizer should be operated by trained professionals, and record the operation of the sterilizer, especially the on-site conditions and exclusion records of abnormal conditions for traceability and improvement.
7. The service life of the sterilizer is about 10 years, and the production date is shown on the product nameplate; if the user needs to continue using the product that has reached the designed service life, he should apply to the registration authority for a change in the registration certificate.
8. This product is the product warranty period within 12 months after the purchase, and the replacement parts during this period are free of charge. Product maintenance must be carried out by contacting the manufacturer’s professional after-sales personnel or under the guidance of the manufacturer’s professionals. The replaced parts must be provided by the manufacturer, and the local supervisory inspection department (safety valve, pressure gauge) can be inspected regularly by the local supervisory inspection department where the product is used. The user can disassemble it by himself.
