This HC ultra-low temperature freezer can be used as a laboratory freezer, ultra-low medical freezer, or deep freezer. It is suitable for use in hospitals, health and disease prevention systems, colleges and universities, research institutions, the electronics industry, biological engineering, and more. The Jindal -86°C HC ultra-low temperature freezer SMI-165EJ-677 introduces advanced upgrades to the ultra-low freezer series. Designed for laboratory and medical use, it features a newly structured design with four independent inner doors. The enhanced foaming insulation within the doors ensures superior temperature stability. This ultra-low freezer/lab freezer is specifically engineered to provide long-term, secure storage for high-value medical and laboratory materials.
High-efficiency frequency conversion compressors automatically adjust operating power based on the heat load, making the equipment energy-efficient.
The combination of 130mm CFC-free PU foam and high-quality vacuum insulated panels provides superior insulation, preventing rapid temperature increases and ensuring low energy consumption. The design of foam inner doors, built-in vacuum insulation board and triple independent silicone sealing strip design make the insulation performance excellent.
The ULT freezer uses natural green gases as refrigerants to meet safety requirements for usage. These natural hydrocarbon refrigerants are SNAP-compliant according to U.S. regulations. Additionally, this is supported by European Union regulation (EU-517/2014). The foaming agents used during manufacturing are fully controlled to ensure they are environmentally friendly.
The intelligent control of the inverter compressor optimizes its running speed based on the conditions. When the inverter compressor is operating normally, it runs for longer periods than a conventional compressor but at a minimal speed. This reduces power consumption and helps maintain a stable freezer temperature. When the door is opened, the compressor adjusts its speed to quickly bring the temperature inside the freezer back down to the set value before resuming its normal cycle.
The cascade system consists of two independent refrigeration cycles: a low-stage cycle and a high-stage cycle. These cycles are connected through a cascade condenser. The high-stage and low-stage systems operate separately using different refrigerants, with the evaporator of the first cycle cooling the condenser of the second cycle. The first stage lowers the temperature to -40°C, while the second stage further reduces it to -86°C using natural refrigerants.
Equipped with an Embraco compressor and high-quality EBM fans from Germany.
Utilizes a patented CFC-free hydrocarbon refrigerant for fast cooling and eco-friendly operation.
