II. Cold room panel, size, and temperature: 

    The storage temperature is displayed and controlled by the digital thermostat with which reliable storage is provided; modular cold room is a new product with various standard sizes. Its storage capacity may be specified or selected according to the requirements of the customer. 

III. Application of cold room: 

    Food (meat, vegetable, fruit, dairy, drink), medicine, chemical, electronics, etc. Cold storage are widely used in food process factory, dairy factory, pharmaceutical factory, chemical factory, fruit and vegetable warehouse, egg storage, hotel, supermarket, hospital, blood bank, troops and laboratory. 

   The precise control and adjustment of temperature enables the customers to achieve the utmost efficiency and benefits. 

   All panels are made tongue and groove edges and are locked together with cam lock fasteners, which can be unscrewed easily with a hexagon.

Polyurethane Foaming Machine

Insulation layer: polyurethane insulation foam

   The cold room panels are manufactured here with the raw material like color steel plate, stainless steel 304, galvanized sheet, polyurethane foams.

Cold room panels has such features:

1)good fire prevention performance and not melting when burning

2) wide temperature application range, small contractility even in low temp environment and non fragile.

3) nontoxic and inodorous, in accord with the state environmental protection requirements

Cold room panels in our factory

    Cold room panels thickness usually made according to the room temp, and the sized can be customized.

The table below shows the room temp and the panels thickness demand:

    We have 2 compressor brand types for your choice: German bitzer, American Copeland

Condensing unit

Germany Bitzer cold room unit from 2HP to 50HP

    This series products feature box type structure with hermetic and semi-hermetic compressor, that is compact and pleasant looking, applicable to cold display cases, cold storage rooms, ice producers etc.

America Copeland cold room unit

Air cooler

Features of the air cooler are as following:

 1) This kind of air-cooler is specially designed for preservation, refrigeration and cold storages

 2) The shell is made of quality steel plate; sprayed plastic surface is anti-corrosive, and its appearance is handsome

 3) Coiled pipes are mechanical expanding tubes in staggered arrangement; therefore, copper tubes and aluminum sheets are combined closely.

 4) Long-distance air supply ducts can be used. 

Air cooler in our factory

Control box

    Just a start press, you can control the system automatically, without human operation. When the room temp drops to the lower limit of the set temperature, the compressor and air cooler will stop working automatically; When the room temp rises to upper limit of the set temperature the compressor and air cooled will start to work automatically.
