For marine, construction and industrial cabs

No other heater offers as many options as the R-2020. This heater can be used in vehicles with water or air cooled engines (where oil is the heat source). The compact design with round tube and fin core construction encourage unit mounting in any position while withstanding high operating pressures. The versatile mounting features and defrost attachments are perfect for multi-purpose applications in off-road and construction vehicles. The R-2020 can also be used as a heat exchanger or oil cooler with its "O" ring hose fittings and high-pressure core construction.
