Water heaters Thermo Top Pro 50
Light and powerful The Thermo Top Pro 50 heater is the advanced successor to the Thermo Pro 50 Eco, specifically designed for lightweight trucks and small to medium-sized commercial vehicles. It retains the compact dimensions and lightweight design of its predecessor while introducing an enhanced HDSCS connector, making the heater more robust and simplifying installation. Thermo Top Pro 50 now features both LIN-Bus and analog signal input, offering maximum flexibility for seamless vehicle integration. Enhanced components, such as a new blower module and coolant fluid pump, significantly boost the heater’s efficiency. With additional time-tested features, such as an automatic altitude adjustment, Arctic Start and continuous heating control, extreme environmental conditions can be managed easily. By efficient pre-heating of the engine, the Thermo Top Pro 50 makes the vehicle more ready for use, especially in harsh environmental conditions. At the same time, it contributes to more economical, environmentally friendly and wear-reduced operation.
