Omega Environmental Technologies is now distributing evaporative cab coolers from Dirna S.A., a leading air conditioning company based in Madrid, Spain. The Dirna product is different from traditional engine-dependent, Freon-based cooling systems in that it requires no fuel or Freon to operate. Rather, it runs off a low battery charge, cooling the vehicle cab through natural evaporation. Omega is offering both roof and rear installation models for new or retrofit applications serving long-distance trucks, delivery vehicles, heavy-duty equipment and off-road and agricultural machinery.
