End Cross Tubes (High Efficiency Tubes) are manufactured out of plain Copper and Stainless Steel Tubes of size : 15.88mm and 19.05mm OD Tubes with plain tube thicknesses of minimum 0.55mm upto 1.25mm.
This End Cross Tubes are used extensively for Vapour Absorber Chillers (VAC). Absorption Chillers are generally used, Steam or hot water to drive the lithium bromide refrigeration cycle but certainly can use some other heat sources as well.
Absorption Chillers are widely applied in Industries, viz. Manufacturing Precision Machinery, Aviation and Aerospace, Textiles, Electronics, Electric Power, Metallurgy, Pharmaceuticals, Chemicals, Hospitals, etc.
End Cross tubes are manufactured out of Copper and Stainless Steel Tubes with externally enhanced and with Internally ribbed. Plain tubes with lower thickness ranging from 0.5mm upto 1.00mm is used, for processing End Cross Tubes.
