Rapid cooling
VIP
- Heat insulation index is 13 times as high as traditional PU foamed materials and thermal conductivity is＜0.0018W/m•K
- Thickness of foamed wall is decreased to 70mm without cooling performance reduction or external dimensions change
User-friendly design
- Ergonomic latch plus optional padlock provides more user-friendliness
- Standard electronic code lock (VH smart series) for card-swiping or fingerprint unlock
- Controller with delay start function enables off-peak start for 0~30min, significantly reduces the load on electric circuit from simultaneous start-up
Safety design
- Original import compressor plus cascade cooling system with HC refrigerants realizes rapid pull-down after door opening and ensures sample safety Standard expansion tank to absorb system pressure in case of excessive pressure caused by extremely high ambient temperature or any other reasons, to maintain normal compressor operation and ensure sample safety
- Core parameters protection with password to avoid losses caused by mis-operation
Sealing design
- Quadruple-pane door gaskets are distributed on different planes to form a vacuum protection area to prevent cold air loss and reduce frost growth
- Wholly foamed inner door with thickness ≥30mm
Environmentally friendly
- Compared to products with the same capacity, energy consumption is reduced by 30%;sealed refrigerant is significantly reduced (less than national standard 150g), safe and reliable
- Freon-free refrigerant
- Energy consumption for each cryo-tube is reduced to a new low
I. Application Scope
The equipment serves for preserving biomacromolecules, cells, tissues and organs (e.g., human organs, tissues, whole blood, plasma, serum, biological fluids or treated biological samples (DNA/RNA/protein, etc.)).
II. Key Indexes
1. The freezer is controlled by microcomputer with digital temperature display. The adjustment unit is 0.1℃. The temperature inside is adjustable within the range from -86℃ to -50℃. The wide climatic zone design is suitable for operation under ambient temperature from 10℃ to 30℃.
2. The freezer adopts the cascade refrigeration system with fast cooling speed. It takes fewer than 270 min to drop the temperature from 25°C to -80°C.
3. The freezer is equipped with standard expansion vessel to maintain normal operation of compressor when the refrigeration system experiences an excessively high pressure due to high ambient temperature or other reasons.
4. Available Volume: 861 L.
5. External Dimensions (W × D × H): 1180 × 875 × 1990 (mm).
6. Internal Dimensions (W × D × H): 1040 × 600 × 1380 (mm).
7. Net Weight: 370 Kg.
8. Power: 920W.
9. Exterior Materials: Galvanized steel sheet, polyurethane foam and VIP vacuum insulation structure.
10. Interior Materials: Galvanized steel sheet painted with polyester resin powder.
11. There are 2 interior doors (both with lock catches) made of stainless-steel framework and ABS resin plate, and 1 outer door (with lock catch available for padlock) made of galvanized steel sheet, polyurethane foam and VIP vacuum insulation structure.
12. The freezer is designed with three-dimensional door strip seal rather than planar multi-layer. The holistic 4 layers of door strip seals are distributed in different planes and forms multiple airtight protective layers, so as to avoid the leakage of cold air and frosting to its largest extent.
13. The “innovative design” of integrated door lock handle and compact caster is flexible and more convenient, and available for padlock.
14. Thermal Insulation Layer: Rigid foaming polyurethane and VIP (vacuum thermal insulation layer) technology; the formed layer is not thicker than 70 mm; thus, the storage space is increased by over 20% and the sample storage capacity is increased by over 25%.
15. Inspection Hole: With a diameter of 17 mm (at the back and the lower left corner).
16. The compressor imported from Japan matches the original and mature Japanese cascade refrigeration system, which guarantees stable and safe operation. Refrigerant: Hydrocarbon refrigerant, which is completely environmentally friendly and pollution-free. Refrigeration Mode: Direct cooling. Energy Consumption: Lower than 10.9 kW·h/24h.
17. Condenser: Finned copper tube condenser, with good heat dissipation performance. The filter screen of condenser is easy to replace and rinse.
18. Safety Devices: There are multiple fault alarms, including high/low temperature alarm, high ambient temperature alarm, compressor protection alarm, abnormal sensor alarm, outage alarm and remote alarm output. Two types of alarm methods (Buzzer alarm and code-displaying alarm); all individual components are well earthed.
19. Standard Configurations: 3 layers of shelves, 1 defrosting shovel, 1 set of keys and 1 user manual.
20. Power Supply (V/Hz): Single-phase source at 220 V/50 Hz.
21. The freezer is equipped with casters and standing legs for supporting and stabilization.
22. Controller Functions: The controller is designed with the boot-up delay and can be set with a peak-shifting boot-up for 0 ~ 30 min, reducing the load to circuit due to simultaneous boot-up; the password protection mechanism for display can designate different permissions based on operators; temperature data output via MODBUS communication (optional); USB data export.
23. Users can choose their freezing storage boxes.
24. Gas： R290and R170
