The students can learn the cold storage unit design, load calculation, electrical design, warehouse design, cold storage management, cost estimates and other aspects skills. It can simulate the control principle and workflow of real small freezer. Small Freezer Training Equipment includes three main parts of electrical control systems, refrigeration units, and real storage room.

The blast freezer and fluid bed sections are contained, along with the fan and evaporator, inside an insulated cabinet. Inside the cabinet, a fan with adjustable impeller transports air from the interior of the cabinet into the freezer ducting and through the evaporator tube bank where it transfers heat to the refrigerant. Access doors to both sections are fitted with observation windows and an electrically heated surround to prevent the doors from freezing in the closed position.
The blast freezer section contains 5 trays on to which the food samples to be frozen are placed. The air, now reduced in temperature, passes trought he tray section which can be observed through a removeable perspex panel. It then changes direction and passes vertically up through the fluid bed section, back into the cabinet space where it is again circulated by the fan.
There is a facility for a suitable anemometer to be inserted into the ducting to allow the air speed to be measured. There is a facility for thermocouple sensor leads to pass into the ducting and through the cabinet wall so that freezing temperatures and rates can be monitored externally.
Intended use:
Used in wide range of laboratory services from hospital laboratory to reference centre. Self-adhesive stickers for labelling samples or reagents to be frozen.
