R-2020-0P Red Dot Auxiliary Heater / Defrost / Oil Cooler – 12V

Description

The Red Dot R-2020-0P Auxiliary Heater, Defrost, and Oil Cooler is engineered for demanding mobile applications where flexibility and durability matter. This unit can be used in vehicles with water-cooled engines or air-cooled engines where oil is the heat source, allowing it to function as an auxiliary heater, defroster, heat exchanger, or oil cooler depending on system configuration.

Its round tube-and-fin core construction is designed to withstand high operating pressures while allowing the unit to be mounted in virtually any position. The compact design supports installation in tight spaces, while universal mounting features and compatibility with defrost attachments make it well suited for multipurpose applications in off-road, construction, agricultural, and specialty vehicles.

The R-2020-0P uses 5/8-inch push-on heater pipe fittings for straightforward plumbing and delivers reliable airflow for consistent heat distribution. As a heater-only unit with multi-function capability, it is ideal for OEM replacement or custom auxiliary heating and cooling systems.
