I've spotted this Hyundai H100/Porter/Bakkie fitted with a roof-mounted evaporative cooler (or alternatively "swamp-cooler") a few months ago in my hometown, Porto Alegre, located in Brazil's most southern state, Rio Grande do Sul. Altough air-conditioner is an optional feature for the H100 in many markets, it was not available in Brazil, but the thermal comfort issue was addressed with the evaporative cooler, a very popular aftermarket item for commercial vehicles in Brazil. It works more effectively in dry climates, since its cooling principle is based on increasing the air relative humidity, but it also has a good effect decreasing static electricity loads and the amount of suspended dust aboard.
