Description

Jindal Ultra Low Temperature Freezers used for storage of various samples, sensitive stem cells, plasma, semen, virus, bone graft and other biological samples. The outer chamber is made of color sprayed steel and inner chamber is made of anti-corrosion quality stainless-steel 304 grade material. Freezer has 3 nos. of inner individual compartment storage compartments with insulated doors and adjustable height. Door is sealed with Triple silicon section fitted with decompression valve facility to lower air pressure inside the freezer for easy door opening. Freezer door latch allow one hand operation handle opening & closing. Door is fitted with heavy duty handle include door key lock as well as padlock provision for added security and sealed with multiple layers rubber gasket to avoid temperature leakage for sample security. Exterior illumination of freezer ensures for long term viability and enhanced temperature uniformity ±3°C. The Freezer inbuilt heavy-duty fume universe castors with locking. Freezer has 100 mm ground clearance.

The Freezer insulated with polyurethane foam (PUF) vacuum insulation panel 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. Condenser is made of copper coil. Freezer has frost management with adjustable cabinet heater. The filter also is washable condenser filter indicator which keep fins free of dust to maintain peak cooling efficiency. 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 cooling system 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.
