Importance of Ultra Low Freezing Tests in Quality Assurance

Deep freezers are equipments that are used to store and preserve food for a longer period of time i.e. essential for industrial purposes as well as for household chores. These are even used in restaurants and super markets. There are different kinds of deep freezers such as deep freezer vertical, freeze drier, ultra –low deep freezer and blood bank refrigerator. They are available in different shapes and sizes some may be compact or some may be the regular ones. Their functions and applications vary as per their usage. In this post we will learn about the role of ultra low deep freezer in quality testing.

The testing apparatus

It is equipped with an air cooled compressor and CFC free refrigerators. These systems are installed to provide efficient cooling and consistent flow in the cabinet. High capacity air cooled condensers with aerodynamically shaped fans and washable condense filters keep the environment within the freezer free of fine dust. It can provide an insight into the characteristic mechanical behaviour of polymers/ rubber at low temperatures. The initial stages of the procedure involve establishing a satisfactory technique for low-temperature testing. Simple temperature effects include glass transition, effects on solubility and first-order transitions (crystallization), besides other effects associated with plasticizers.

It adheres to ASTM standards. The equipment is finished in Autumn Grey & Blue combination painting and bright chrome / zinc plating has been added to impart a corrosion resistant finish. The Instrument comes complete with an instruction manual; Electrical Wiring Diagram & Calibration Certificate traceable to NABL approved Labs.
