FD- series coolers , medium-low temperature range of the variable fins pitch 12-6 mm.
All coolers are made of galvanized painted steel 1.5mm , 2mm drain tray , heating elements made of stainless steel , copper tube wall thickness of 0.4mm fins thickness 0.2mm . Aluminum plates are coated with anticorrosive Hydrophilic. Due to the special properties of the coating , water droplets formed on the plates quickly drain into the pan without compromising the heat-transfer . Defrost water drops just do not stay on the plates , which makes more efficient defrost . With the best heat-transfer properties as compared with the aluminum oxide coating Hydrophilic improves heat transfer by 5%.
