Ultra low temperature -50, -60 cold storage for tuna, cold room Shasimi air blast freezer

air blast freezer

Needless to say, -20~-35C temperature is suitable for most frozen products, including beef, chicken, ice cream and seafood, etc. But when it comes to some special products, -50~-60C ultra low temperature cold room is a must. For example, we can’t put the frozen tuna in a -30C freezer room.

Quality is very important and now we’ll tell our basic design.


1# Refrigeration equipment

It’s quite easy to design refrigeration equipment for a chiller room, freezer room and blast freezer. We can use monoblock refrigeration units, which is easy installation and no need commissioning. We could also use split systems, with a good price and original new Bitzer compressor. And, We could also use a compressor rack systems, which is power-saving, spacing saving and operation-friendly.

But when it comes to -50~-60C, we could no longer use the same design. A normal design evaporator can’t work well.

With authorized technology from our European partners, we could give you a high quality -60C refrigeration systems, which is long-lasting, power efficiency and easy operation & maintenance.

We would use Bitzer compressors, Mycom, SRM, Hitachi screw compressors, etc. They has different characteristics and we would listen to customers before the quotation.

2# Insulated panels

High-density 42kg/m3 is a must. PU panels with cam lock is a good choice. But best choise is PIR panels.

3# Insulated doors

It should be a good design, with both the doorframe heater and doorsill heater.

4# Installation and commissioning

That’s very important. So we would send our engineer on site to provide these services.

5# Power saving design

As for these ultra low-temperature blast freezer, power saving is very important. Supposed we improve it by 20%, it will make huge difference on the electric bill.

6# Others

Rack systems, electric connection, light, forklift, etc. All are not the same as a normal freezer room.
