Environmental Quality Operation Program
The lighting and wiring replacement projects are implemented within the framework of the OP CFP (Slovak Innovation and Energy Agency and the European Regional Development Fund) in order to reduce energy consumption and achieve the planned savings in operating costs. The aim of the projects is to improve the quality of lighting in workplaces by, in particular, increasing the intensity of lighting and improving the lighting uniformity. The new lighting and wiring systems take account of the extreme environment-related demands, such as dust, chemicals, vibrations, and ambient temperatures in order to reduce servicing interventions to a minimum and to allow cleaning the equipment with pressurized air or water.

DUSLO a.s. “Renewal of production unit lighting systems” – the project aimed at the renewal of lighting systems in 6 production factories with 3-shift non-stop operation, where workplaces are illuminated by artificial lighting systems covering the entire layout of each production hall, in a highly dusty and corrosive environment. The implementation of the contract includes the full replacement of cable routes, cabling, and lighting technology with a large share of innovative technologies (LED lights, intelligent DALI light control system)
