Roll-bond panel

KUMZ produces rolled-bond panels of the following nomenclature

Type of channel inflation	Blank thickness, mm	Width, mm	Length, mm	Height of the main channels
Double side	From 1.1 up to 2.2	From 250 up to 1030	From 320 up to 2800  (on request up to 4000)	4,5 ± 0,5 mm; 10 ± 1 mm
One side				3,2 ± 0,4 mm

Material: aluminum 1100, 1200, 1050 and 1080 according to EN 573-3;

Due to the high efficiency of heat exchange, rolled-welded panels are used for 
- household refrigerator evaporators;
- solar collectors;
- photovoltaic panels;
- cooling of electric vehicle batteries.

Additional requirements:
    Volume tolerance ±5%;
    The tolerance for the length of the pattern is ±2%;
    The tolerance for skewing the pattern is ±3%;
    Tolerance for the entire pattern = Tolerance for the length of the pattern + Tolerance for skewing the pattern;
    Channel width tolerance:
        Longitudinal ±0.5 mm;
        Transverse ±1.0 mm;
    The minimum internal deformation pressure of the panel is 1.6 MPa;
    Specific moisture content not more than 5 mg per 100 cm3 of internal volume;
    The quality of the inner surface of the channels meets the requirements of DIN 8964, which allows the use of ozone-safe refrigerants.
