IPM, Essen: "50 years Power Drives"


Lock participated again successfully in the foremost horticultural trade fair IPM in Essen. The main attraction was the anniversary "50 years Power Drives" and the introduction of the new power drive EWA 10.

In May 1959 the first Power Drive of Lock was delivered to a greenhouse builder and the automatisation of greenhouse ventilation was born. The original invoice together with the first series power drives "“Type 16"” was shown at the stand.

Just for this anniversary Lock introduced the new Power Drive EWA 10 to complete its range of Power Drives EWA 10 – 16.
