DC Low Temperature Car Freezer -25/-40/-60 ℃

DC low-temperature car freezers are crucial for transporting temperature-sensitive goods, especially in fields like pharmaceuticals, medical supplies, food preservation, and research. These freezers, designed to operate efficiently in mobile environments, offer a wide range of temperature settings, including -25°C, -40°C, and -60°C. Such flexibility allows users to store a variety of materials, ranging from vaccines and enzymes to frozen foods and biological specimens, during transit.

One of the key advantages of these DC low-temperature car freezers is their ability to run on a vehicle's DC power supply, typically from a 12V or 24V system, which makes them highly versatile for transportation. Unlike traditional AC-powered freezers that require external power sources, these DC units draw power directly from the vehicle's battery, making them ideal for long-distance travel or remote locations without reliable access to electricity. This feature ensures that materials can be stored at the required low temperatures, even when conventional power sources are unavailable.

The temperature ranges offered by -25°C, -40°C, and -60°C models allow for precise control over the conditions inside the freezer. While -25°C is typically sufficient for food items and some pharmaceutical products, the lower temperatures of -40°C and -60°C are crucial for materials that require more stringent conditions, such as biological samples, vaccines, or cryogenic materials. Maintaining such low temperatures over long distances is made possible by advanced insulation systems and efficient compressor technology that minimizes energy consumption while ensuring stable internal temperatures.

Safety Certification of Portable Ultra Low Temperature Freezers

Portable ultra-low temperature freezers are widely used in medical, pharmaceutical, and research settings to store valuable, temperature-sensitive materials. These materials may include vaccines, biological samples, enzymes, and certain food products, all of which require precise temperature control. Given their critical role in preserving the integrity of such materials, it is essential that portable ultra-low temperature freezers meet stringent safety standards and certifications. These certifications not only assure reliability and performance but also ensure the safety of both the stored goods and the users.

The safety certification of portable ultra-low temperature freezers typically includes several factors, such as electrical safety, mechanical safety, and temperature control accuracy. These units must comply with various international and regional standards set by regulatory bodies, including the International Electrotechnical Commission (IEC), the Underwriters Laboratories (UL) in the United States, and the European Union's CE marking. These organizations ensure that the freezers meet specific safety requirements, including proper insulation, electrical grounding, and protection against electrical shocks.

One important aspect of safety certification is the approval of the freezer's electrical components. Portable ultra-low temperature freezers are equipped with powerful compressors and electrical circuits to maintain temperatures as low as -40°C or -86°C. For this reason, the freezers must undergo rigorous testing to ensure that their electrical systems are protected against short circuits, overloads, and malfunctions. Certifications like UL 60950-1 in the U.S. or IEC 60335-2-89 internationally ensure that the electrical systems are safe to use and comply with industry standards.

Another critical certification aspect is the freezer's mechanical integrity. This includes testing for pressure resistance, stability, and durability under normal operating conditions. For example, the freezer must be able to handle the constant operation of compressors without risk of mechanical failure. Safety certifications ensure that the construction materials used, such as the insulation, outer casing, and seals, are durable and resistant to physical damage, preventing leaks or loss of cooling power.
