Click image for Hydronic 30
specification
The Hydronic is available in the power
stages 16kW, 24 kW, 30kW and 35kW- another advantage when
stocking spares.
Small and compact
Making installation and replacing existing
systems easier.
Low cost
Specially developed for busses the operating
costs are low and the heater is recyclable.
Low noise
Passenger and residents will appreciate
the new Hydronic design which greatly reduces noise.

The driver and passengers
get onto a preheated bus. The windows are free from ice
and clear. The engine is ready to go. This saves fuel during
starting and spares the environment. The Hydronic also ensures
maximum comfort during waiting periods and breaks, in traffic
jams and in stop-and-go traffic.
Small, light and quite
The heater can be integrated into the
engines cooling water system.
Temperature control
The intelligent, electronic monitoring
system controls temperature using two sensor elements, rather
than the less reliable overheat switch and fuse.
Water heat is controlled at the heater inlet to a constant
medium temperature and limited at the outlet for the water
cooling system.
Efficiency
The electronically controlled combustion
point produces less strain on the buses electrical system.
Safety
The single line (option) needs no return
pipe from the fuel pump to the tank. This reduces pressure
in the fuel pump and the chance of fuel leaks.
Repairs and maintenance- The Hydronic's a modular system
which means stocks of spare parts are greatly reduced, and
therefore so is service time.

How the Hydronic works
On starting the heater draws in combustion air
(1) from the engine area or where the heater is located.
Fuel is drawn (2) from the tank and mixed with
the combustion air.
A glow pin (3) ignites the mix and a controlled
flame is established in the heat exchanger (4). The integrated
water pump (5) now circulates the system’s water, passing
it over the heat exchanger and onto the calorifier and radiator
system (6).
Once the system is hot, the heater will regulate
down to a lower heat level. This avoids unnecessary cycling
and thus avoids wasteful repetition of the start cycle.
The heater in lower, or stepped output
tops up the system to maintain optimum temperature.
When heavy demands are made on the system, such
as showers or a fall in outside temperature, then the Eberspächer
steps up again to regenerate the heat in the system.

All the components that go into making
a full installation are purpose designed to work together
reliably and withstand a tough environment.
