Hello everyone I am Jacob, the Design Engineer at Calpak. Calpak is a Greek company based in Athens, that specializes in solar thermal equipment, particularly solar water heaters and solar collector. We will order 100-200 pieces each time, few times a year. We are looking for a specific electronic switch for water pumps like the one in the picture. If you have something like that available, let me know. We are not only looking for a supplier but for a long lasting collaboration, so please give me your best price and let's start this collaboration.
Be well,
Farkonas Iakovos (Jacob)
