4 Dryplus-3 shell & tube evaporators Dryplus-3 series of shell and tube evaporators represent the natural technological evolution of a generation of heat exchangers leader in the air conditioning and refrigeration applications. The models of the series ensure cooling capacities up to 1500 kW at nominal conditions, from 1 to 4 independent cooling circuits, 3 different baffle distances depending on the working water flows and 3 different positions of the water connections. In particular, the evaporators have been optimised for operation with R407C refrigerant. The adoption of a dedicate, high...

Dryplus-3 shell & tube evaporators 5 Perfection in construction Alfa Laval shell and tube evaporators include the results of a research intended to ensure a high level of mechanical strength and resistance to vibration and corrosion. The “U” design of the tube bundle allows the thermal expansion between the tubes and the shell avoiding any tension. Thanks to this solution the tube bundle can be extracted from the shell for inspection or maintenance (starting with model DX_56) and it is possible to rotate the shell in order to change the water connection position. The material choice is...
