Fluid heaters for buses

Liquid heaters "Spheros" firms established in more than 150,000 coaches in the world - strong evidence of competence and reliability. They are compact, and therefore can be embedded even in buses with low-floor. Monitoring is carried out automatically by the control unit, which is a function of temperature switches it into polnogo- mode, partial load or pause.

Currently, the company produces four fluid heaters: DBW 160, DBW 230, DBW 300, 350. Fluid DBW DBW series heater - a heating device operating on liquid fuel independently from the motor road vehicle. As the coolant (working fluid) is used in the coolant heaters DBW series. Fluid circuit is connected to the engine cooling system, and the heater is connected to the fuel system and the electrical system of the vehicle. The heater can be operated and the fuel supply from a separate reservoir. In conjunction with a heating system DBW series heater is designed for:

• cabin heating or the passenger compartment of the vehicle
• heating and maintaining the heated state of the motor vehicle

Due to exceptionally low fuel consumption, minor pollutant emissions and practically silent operation DBW series heaters are classified as environmentally friendly. The heaters DBW type produced in accordance with the requirements of technical specifications:
