Our cold rooms and freezers are available from smaller sizes to bigger walk-in models.
There are no any dimension limits we can do any sizes and variations what our
customer needs. Special sizes can be adapted to any storage space or facility what
customers have. Our partners are feeling free to plan their storage capacity based on
our specific system. Cold rooms and freezers can be connected to each other.
In commercial cases it is strongly recommended to connect all of the cold rooms and
freezers to each other. To use this option end users can save installation costs and
useful spaces.
Our products are available for cold and freezer storage as well as any other different
purposes. Generally used temperatures for cold rooms is 0 /+ 5 C, while freezers are
working between –18 C and –20 C. Our products are equipped with digital
thermometer and automatic controlled electronic. Customer can set parameters of
temperature and easily check room temperature on the LED/LCD display. Any other
functions (such as defrosting, dripping, alarms, on-off circles) can be managed by the
automatic electronic control system.

Both commercial walk-in cold and freezer rooms can be built by painted metal or
stainless steel. For special purposes we can use other materials as well. For example
PE coated or wooden patterned walls.
With or without floor:
While walk-in cold rooms can be used with or without insulated floors, freezer must
have insulated floors. Because installation cost saving and hygienic reasons we
usually do not propose to use insulated floors in positive temperature cold rooms. On
other hand energy savings also a relevant question in these days.
End users can save more than 30% of energy costs with insulated floor in a normal
cold room. Immediate cost saving can arise if we leave insulated floor, but in long
term it is possible to return its additional costs within few years because the energy

saving. Lack of insulated floor has another additional advantage: easier cleaning of
floor in case of storing of meat/milk or other dripping products.
Obviously customer has to make a decision about insulated floor of cold room.
Remember: freezers must have insulated floor.
