Blast Freezer -40 C Manufacturer,Supplier and Exporter in India
Product Code : EL-RACLE-12805
Jlab Export is a leading Blast Freezer -40 C Manufacturer,and suppliers in India
A blast freezer pulls food down to freezing quickly by blowing very cold air across it, so the ice crystals that form are small. This free-standing stainless steel unit holds 120 litres on stainless steel trays and works from -40 to 3 °C. Fans move the cold air by forced convection, an LCD display shows the settings, and it runs on R-404A at 220–240 V, 50 Hz.

Pull-Down Experiments with the Blast Freezer
The main test is how fast the unit pulls a load down. Students fill sealed packs with water or food, push a Digital Stem Thermometer into the centre of one pack and log the core temperature every few minutes. The plotted curve shows the fall to 0 °C, the flat stretch while the water freezes, and the drop beyond it. Running the same packs in the Chest Freezer shows how much longer a storage freezer takes.
On the refrigeration side, trainees fit the Manifold Gauges For Refrigeration Systems and read the evaporating temperature on the R-404A scale during the run. They compare it with the temperature of the air leaving the coil, since a small difference between the two is part of this design. After any repair the circuit is recharged by weight from a cylinder of R-404A Refrigerant.
Frequently Asked Questions
How is a blast freezer different from a chest freezer?
A chest freezer is built to keep food that is already frozen. A blast freezer blows very cold air over warm or chilled food to freeze it fast. This unit works down to -40 °C with forced convection.
What temperature range does it cover?
It works from -40 to 3 °C. The low end is used for fast freezing, and the top of the range lets the cabinet hold food just above freezing as well.
Why does fast freezing matter for food?
Food frozen slowly grows large ice crystals that break cell walls, so it loses water and texture when thawed. Fast freezing forms small crystals and takes food quickly through the temperature band where bacteria grow fastest.
What refrigerant does it use?
This model runs on R-404A, a refrigerant blend used in low temperature commercial equipment. Service it with gauges that carry an R-404A scale and charge it by weight to the nameplate figure.
How much floor space does it need?
It is a free-standing unit measuring 31.5 x 31.5 x 39.37 in (L x W x H). Leave a clear gap around it so air can reach the condenser.
