Heisterkamp Transport B.V

Chief operating officer.

Every initiative aimed at reducing emissions deserves careful consideration for its feasibility. Thanks to the SolarOnTop solution, we effectively cut our truck's fuel consumption by a percentage that justifies the investment and enables us to make a step towards a greener environment.

Van der Linden Hillegom B.V


For us, the motivation was to ensure that the air conditioning and refrigerator continue to work during the break in the daytime (in our work, the moment when we go to sleep). We now have a perfectly working system in which the driver can enjoy a cooled break, even in temperatures above thirty degrees without running the vehicle.
