Description

The Jindal SMI-165EJ-777 Ultra Low Temperature Freezer, with a temperature range of -40°C to -86°C, stands out as a top performer in the ultra low temperature freezer market. Designed with a next-generation refrigeration system, it delivers rapid and reliable cooling. Its advanced microcomputer control system, combined with platinum resistor sensors, allows precise temperature adjustments within the specified range. The freezer features comprehensive thermal insulation, incorporating high-efficiency VIP Plus vacuum insulation panels on all six sides of the cabinet to enhance energy efficiency and maintain stable internal temperatures. This upright freezer is well-suited for hospitals, blood banks, public health organizations, academic institutions, research centers, and biotechnology applications.

High-Performance Refrigeration System

The -40°C to -86°C Ultra Low Temperature Freezer SMI-165EJ-777 features a next-generation refrigeration system that ensures rapid cooling. It reliably maintains internal temperatures within the -40°C to -86°C range. The CFC-free mixed refrigerant delivers excellent cooling performance while being environmentally friendly.

Advanced Vacuum Insulation Technology

The deep freezer is built with high-efficiency VIP vacuum insulation panels on all six sides of the cabinet. Its dual-layer insulated door, combined with a double-sealing design, significantly enhances thermal insulation and ensures uniform temperature distribution within the ultra low temperature freezer.

Advance Insulation System

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.

Eco-Friendly

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.

Energy-Efficient

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. 

Cooling system Diagram

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.
