Fluid heaters
«Spheros» fluid heaters – it is a combination of the
newest and verified during a lot of time technologies, providing comfort for
drivers and passengers, maximum reliability and efficiency. Considerable proof
is the fact that «Spheros» heaters are installed in more than 150000 buses
through the whole world.
In buses, trucks and commercial cars, construction
engineering and engineering of a special purpose «Spheros» heaters are used for
prestarting warming up of an engine to the operational temperature, for heating
of driver`s cab and passenger compartment of means of transport.
«Spheros» heaters – it is a trouble-free starting of a
motor even under the conditions of the bitterst frost, what considerably
reduces wear of connecting rod-piston group, fuel consumption and consumable
materials, decreases a total load to the accumulator and loss of time not only
for warming up , but also for motor repair, what is inevitably at its constant
cold starting.
«Spheros» heaters operate independently of a vehicle
motor – both before its starting (e.g., at a stop) and during its work. They
have its own system of fuel supply – from standard or additional fuel tank.
«Spheros» heaters are compact, that is why they can be
built in even in low floor buses.
Operating control of a heater is carried out
automatically with a control unit, which depending on the temperature switches
to the modes of a whole or partial load or pause.
Using of the most up-to-date technology, a high
quality of production and presence of some control systems secure maximum
reliability and a whole safety of «Spheros» heaters operation.
Due to exceptionally low fuel consumption, insignificant emission of noxious substances and practically noiseless operation «Spheros» heaters rate to the environmentally safe category.
DBW series fluid heaters – it is deservedly popular
type of heaters, used in vehicles equipped with diesel motors.
In DBW series fluid heaters coolant is used as a heat
carrier– fluid circuit of the heater is connected to the vehicles systems of
cooling and heating. The heater is also connected to the systems of electrical
equipment and fuel feeding and is able to work when fuel feeding from a
separate tank.
THERMO E series fluid heaters– they are the newest
diesel heaters, possessing the possibility to work on alternative types of
fuels. THERMO E, with considerable reserves, meets the requirements to the
level of noxious substances emission when exhausting.
Сonstructional features of THERMO E series heaters
are:
- intergrated control unit with moisture protected
joints, ensuring more high level of reliability;
- improved heat exchanger, ensuring a high calorific
power at a small fuel consumption;
- a low level of exhaust gases emission.
Spheros is the only producer of the heaters, developed
specially for vehicles, operating on gas, particularly for buses, in the world
.In GBW series heaters both compressed natural gas (CNG) and condensed gas
(LPG) are used as a fuel.
In GBW gas heaters the advantages of gas as a fuel are
used: a low level of exhaust gases emission, noiselessness of operation is
higher than of diesel heaters.
As diesel units, GBW heaters operate in accordance
with the principle of heat exchange and is controlled with thermostat. Heat,
generated as a result of gas mixture combustion, warms liquid in heat
exchanger, circulating pump runs warmed liquid through heating system of a bus,
providing warmth and comfort in a compartment and preheating of a motor.
THERMO AC/DC electric heaters are mainly intended for
up-to-date ecological transport – buses with hybrid, electric and hydrogen
motors.
On the board of a vehicle the heaters are battery
supplied and operate both from alternative current (AC) of 400 V voltage and
direct current (DC) – 600 V.
THERMO AC/DC heaters are also able to be used for
electric heating of hydro- and cooling systems of buses and means of transport
indoors or for electric heating of trolleybuses. In such cases power supply of
the heaters is carried out from external source of electric power.
Considerable advantages of THERMO AC/DC heaters are: a
complete absence of noxious substances emission, a high energy efficiency
(98%), ability to work at low temperatures of environment, a high level of
reliability and minimal cost for maintenance during the whole service life.
