Hörbranz, Austria – As global use of renewable energy sources rises, Sonderhoff, a system supplier for sealing technology, will highlight solutions for sealing and encapsulation of photovoltaic applications at the industrial fair Hannover Messe 2012. In China, the partner of this year’s fair in Hanover, the solar energy boom still prevails.
On its stand, Sonderhoff will carry out live the foam-gasketing of a photovoltaic housing inverter, using the low-pressure mixing and dosing machine DM 403 from Sonderhoff Engineering in Hörbranz, Austria.
The company will dispense a two-component foam sealing system Fermapor K31 from Sonderhoff Chemicals, designed to fulfil the high demands of photovoltaic applications, into the groove of the housing inverter through the dosing nozzle of the MK 600 mixing head. The mixing head is moved by a powerful 3-axis linear robot system LR HE plus of the dispensing machine DM 403, “with complete contour accuracy,” says Sonderhoff. After curing, a smooth, room temperature cross-linking polyurethane foam sealing forms, which gives optimal protection of the technical inner life of the inverter housing.
The same 3-component mixing and dosing machine can also be used for other applications, for example gluing of solar thermal energy modules or encapsulation of photovoltaic junction boxes.
Shortly before the Hanover event, Sonderhoff will also exhibits at Chinaplas in Shanghai for the fourth time. Close to this economic hotspot Sonderhoff operates its own company – Sonderhoff (Suzhou) Sealing Systems Co. Ltd. It has firmly established as a supplier of low pressure dispensing machines as well as polyurethane- and silicone-based sealing,
