Home ≫Ultra Low Temp. >Deep Freezer -86°C >Cascade ULT Freezer SMI-165EJ-1007
The Jindal ULT freezer features a two-stage cascade cooling technology using natural hydrocarbon refrigerants, R290 and R170. Its inverter compressors are programmed to optimize energy efficiency during long-term preservation and to enable rapid temperature recovery when the door is frequently opened, ensuring specimen viability.
The Jindal ultra-low temperature freezer is designed for a wide range of applications, functioning effectively as a laboratory, medical, or deep freezer. It is well-suited for hospitals, public health and disease control organizations, research centers, academic institutions, the electronics and biotechnology industries, military facilities, and deep-sea fishing operations.
High-efficiency frequency conversion compressors automatically adjust operating power based on the heat load, resulting in significant energy savings.
An ergonomic handle, smooth sliding track, and high-precision pressure relief valve make door operation easy and effortless
Three adjustable dividers create four storage layers for organized sample placement. Two inner doors help minimize frost buildup during door openings
The interior is made of durable, easy-to-clean stainless steel (SUS304)
The unit is equipped with four heavy-duty casters and two leveling feet, allowing for easy mobility and stable positioning
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.
