St Augustin, Germany – Hennecke has developed a new horizontal mould carrier to help make hot water tanks semi-automatically with polyurethane in place of expanded polystyrene.
Daikin Europe, based in Ostend, Belgium is using Hennecke machinery to insulate the hot water tank in its range of Altherma floor-standing heat pumps.
Hennecke said it worked with Daikin to develop a time-efficient process and that it makes hot water tanks which do not have thermal bridges.
In the Hennecke system, foaming takes place between the outside of a plastic tank and a plastic sheath which forms a barrier with the metal moulds. Once the tank assembly and sheath are assembled, they move horizontally into the mould. These are pneumatically locked. Foam is added under the plastic sheet which then cures.
