Description
Blast Freezer
Blast Freezer are used for instant freezing of blood plasma, food products etc. it freezes the blood plasma and other samples to -20oC in not less than 60 min. Chest Freezer offer a breakthrough in sample preparation for use prior to cold storage including flexible design, accelerated air flow and a self-contained refrigeration system. Slow freezing forms big ice crystals in the product. The crystals are forming cells and destroy the structure of the product but in blast freezer Fast freezing forms many small ice crystals which keeps the original product safe.
Blast Freezer is double walled cooled units. Outer body of our laboratory refrigerators are constructed out of thick PCRC, pre coated corrosion resistant GI sheet duly pre-treated with primers and rust proofing and painted with long lasting stove enamel or elegantly powder coated. The inner construction is made of stainless steel sheet-304. The 100 mm gap between the walls is filled high grade polyurethane insulation, which ensures maximum thermal efficiency.
Features:
- Microprocessor based control system.(HMI+PLC optional)
- Defrost cycle can be initiated to shut down the compressor and keep the cabinet defrost free.
- Ergonomic and easy to use.
- Superior freezing shelves and anodized aluminum plates
- Fully programmable PLC and USB ports for PC connectivity.
- RS 232/485 connectivity
- CFC/HCFC-free refrigerants maximize cooling and minimize environmental impact
- chart recorder for better temperature monitoring (optional)
- Corrosion resistant interior and exterior
- Incident monitor provides visual and audible warnings of system abnormalities for increased sample protection.
- Digital display and direct settings for maintaining desired operations.
- Castors for ease of movement
- Lockable hinged doors
- 93/42/EEC directive and amendments
- BS 4376-2:1996

Applications:
Cryogenic Freezer
Cryogenic Freezer with temperature range -140oC to -155oC offer mechanical cryopreservation for long-term biological storage. Cryopreservation is the process where cells or whole tissues are preserved by cooling to sub-zero temperatures. The freezer also known as Cryogenic Storage Freezer. At low temperatures, any enzymatic or chemical activity which might cause damage to the material is effectively stopped. Liquefied gases, such as liquid nitrogen and liquid helium, are used in many cryogenic applications.
