ULTRA LOW TEMPERATURE DEEP FREEZER
Make Dinesh Scientific
DESCRIPTION
An ultra-low-temperature laboratory deep freezer is a specialized piece of equipment designed to attain and maintain extremely low temperatures, down to -80°C (-123°F) or even lower. These freezers are essential because they preserve biological samples, reagents, and other temperature-sensitive materials, which is crucial in many scientific and research applications. The following are crucial features and components of typical ultra-low temperature laboratory deep freezers. The AC room has a temperature range of -40˚C to -80˚C, with a constant operating temperature of -80˚C. MOC Outer: CRC sheet with appropriate powder coating. MOC Inner: Trays and Chamber Made of Stainless Steel (SS-304). Insulation: PUF insulation with a high density for more precise temperature regulation. Temperature control options include HMI (PLC TFT Touch Screen Display) or an LCD-based microprocessor-based digital temperature indicator/controller. Digital LED display Process value (PV) and set value (SV)
RANGE OF TEMPERATURE:
Since the freezer may drop temperatures considerably below the freezing point of water, sensitive goods will be protected.
INSULATION:
To reduce heat exchange with the outside world and avoid temperature swings, these freezers have a lot of insulation.
COMPRESSOR SYSTEM:
uses cutting-edge compressor systems and refrigerants made specifically to withstand extremely low temperatures.
PANEL FOR DIGITAL CONTROL:
including an easy-to-use control panel that enables accurate temperature monitoring and settings. For particular uses, some models might offer programmable temperature profiles.
NOTICES AND MONITORING:
Integrated alarm systems that notify users when temperatures deviate from predetermined ranges, protecting materials kept.
INTERIOR STORAGE:
Designed with movable shelves or drawers to maximize sample and container storage of varying sizes.
SAFETY FEATURES:
May come equipped with features like backup power systems, door locks, and password protection to guarantee the integrity of samples that are kept during power outages.
A UNIFORM DISTRIBUTION OF TEMPERATURE:
superior ventilation systems to eliminate temperature gradients that can jeopardize sample integrity and provide even temperature distribution throughout the freezer.
ENERGY EFFICIENCY:
In order to save long-term operating expenses, manufacturers frequently incorporate energy efficiency into the construction of these freezers.
FEATURES:
- Numerous research and storage applications, including low-temperature scientific experiments, the preservation of red and white blood cells, skin, bone, bacteria, semen, biomedical products, ocean products, electronic devices, and low-temperature testing of special materials, can be affordably solved by the Ultra-Low temperature Freezer. It can be useful for blood banks, hospitals, sanitization centers, anti-epidemic stations, electronic companies, university labs, military industries, and pelagic fishing enterprises.
- The external layer is made up of appropriately powder-coated CRC sheet.
- The inner chamber and trays are made of stainless steel (SS-304 grade).
- The quantity of cold air leakage is substantially reduced by using thicker insulation.
- The device is outfitted with a microprocessor-based controller and digital temperature meter.
- Digital display of temperature.
- Simple mobility is provided by casters fitted on wheels.
- Cooling coils are positioned between the inner side of the stainless steel chamber and the foamed-in-place PUF insulation to prevent any chance of FROST FORMATION on the evaporator, which could clog the compressor/condensing unit.
- Helpful in the quick freezing of blood components, vaccines, biological and medical specimens, and other common laboratory freezing applications at low temperatures.
- The cooling chamber’s increased temperature is caused by a more evenly distributed evaporator.
- Eco-friendly compressor and CFC-free refrigerant.
