Deep Freezer-86°C (Dual Compressor) Vertical SMI-165EJDUAL



Jindal Ultra Low Temperature Freezers are ideally suited for use for storage of various samples, sensitive stem cells, plasma, semen, virus, bone graft and other biological samples. The outer body is made of heavy gauge steel sheet with tough powder coated exterior finish and vacuumed polyurethane foam panels and inner chamber and shelves are made of Stainless Steel (304G) sheet. Freezer has 4 nos. of inner individual compartment with insulated doors and adjustable height. Freezer has Triple silicon door seal with double gasket for less loss of cold air during opening and closing of doors. Freezer door latch allow one hand opening & closing. Door is fitted with heavy duty handle include door key lock as well as padlock provision for added surety and sealed with multiple layers rubber gasket to avoid temperature leakage for sample security. Exterior illumination of freezer ensure for long term viability and enhanced temperature uniformity and stability is ±2°C. The complete body is mounted on heavy duty lockable castor wheels for easy movement. Freezer has 100mm ground clearance.
The Freezer is insulated with high density 125mm polyurethane vacuum insulation in conjunction with Environmentally-Friendly Water Blown Foam nanogel VIP panels which help in preventing the loss of temperature, thermal protection and structural strength. Enhanced acoustic insulation helps to reduce compressor sound. The down-feed coil evaporator for efficient refrigerant flow and air-cooled condenser filter to maintain low peak protects samples. Freezer has frost management with adjustable cabinet heater. The filter also is washable for economy and do-it-yourself maintenance.

Freezer has pressure sensitive mechanisms to protect the compressor in long run. The freezer system is H-Drive Information Center (HIC) with adaptive control is designed to detect high and low usage patterns, adjust compressor speeds, and reduce energy without compromising protection. All models use specially designed cascade refrigeration for energy efficiency direct cooling system with dual high efficiency Hermetic sealed compressors with automatically regulate according to the freezer for ultra-low temperature applications. These 1Hp compressors are designed to run at a large voltage band of 190-270V Single Phase AC Supply. A highly efficient cascade refrigeration cycle helps in attaining the required temperature within a short time period. The combination of efficient technology and construction brings the added benefit of considerable energy savings.
Freezer has decompression valve to lower air pressure in freezer for easy door opening. Freezer has facility one compressor fails the other compressor maintains a minimum temperature of -70°C.
