MAXI ACCU COOL – MA – is the ideal accumulator tank for storage of cold water from room climate systems with cooling machines where the cold water tank provides the necessary buffer volume for the system. The excess heat from the cooling machinery can provide virtually free hot water, if an accumulator tank as a preheater is installed, for example, MAGC. MAXI ACCU COOL features 19 mm. closed cell-foam insulation to prevent condensation from forming on the cold tank surface. Thanks
to its low thermal conductivity and high resistance to water vapour diffusion, closed-cell foam insulation ensures high energy savings for the system. MAXI ACCU features dual sets of flow/return connections (400L = G2″F / 600L= DN80 / 1 000L = DN 100), which provide flexible connection and installation options, in addition to a separate G3/4″F connection for air vents, G1″M drain connection as well as G1/2″F sensor connection.
The commercial cylinders in the MAXI series have shown class-leading operational durability for commercial hot water systems through the last 50 years.
