Used a lot for the festival space, EPS provides large scale hand-washing stations that could work well at entrances both delegate and crew, before catering areas, or just dotted around an event. I am sure that if more automation is required for these units, this is something that can be applied via EPS.
Provides 40 washing stations: 6,00 x 4,00 x 1,35m
Preferably requires some water and black water connections, can however also be managed via tanks that EPS can supply.
