SMALL SERIES BENEFIT FROM LARGE SERIES EXPERTISE
Modern, fuel-efficient vehicle engines provide too little waste heat
to ensure an adequate, comfortable and reliable temperature in the
passenger compartment. With its additional electrical air and water
heaters (PTC heaters), Eberspächer offers effective solutions to this
challenge – with different power settings. Over 40 million vehicles
around the world are already successfully heated by virtue of our
expertise with large series.
But Eberspächer does more than this. we have further developed
and adapted our PTC large series technology specially for small
series, too. Now, a standard plug-in connection ensures seamless
integration in suitable heating systems, for example. Or would you
rather have a fuel-operated pre-heater? Here, too, our extensive
portfolio offers you just the right product.
As a manufacturer of innovative vehicle concepts, you can make
the knowledge of one of the largest companies with comprehensive
climate control expertise work for you!

With ranges for high-voltage applications up to 500 V,
Eberspächer's product range includes PTC water heaters that are
already employed in current generations of vehicles with hybrid,
electric or fuel cell drives. The PTC heater elements offer a high
output range and can be adapted to suit typical voltage ranges, for
highly efficient heating in vehicles with alternative drives, too.
Our PTC water heaters that have been specially adapted for small
series cover a high operating voltage range up to 500 V, and boast
an extremely high heat output of 6 kw. The desired heat output is
controlled completely autonomously by the integrated electronics.
Thanks to the specially designed connection, the heaters can be
installed in an existing coolant circuit quickly and without problem,
while the use of standard components for the coolant circuit
ensures especially cost-effective operation. Furthermore, the PTC
technology is absolutely safe and exceptionally reliable – and the
heater can be installed in any desired position. At the same time,
the compact size and low weight are ideally in tune with the needs
of new, lightweight vehicle generations.
THE ADVANTAGES OF PTC wATER HEATERS AT A GLANCE:
System can be integrated in an existing coolant circuit
Cost-effective thanks to the use of standard components for the
coolant circuit
Very high heat output
Integrated electronics control the desired heat output
No restrictions to the heater's installation position
Safe and reliable PTC technology
Compact size and lightweight design
Large operating voltage range

Eberspächer PTC air heaters have been used in series millions of
times over since 1994 and are being constantly further developed.
Today, this highly efficient, economical and lightweight solution is
used all over the world to support the heating function in numerous
vehicles with alternative drives.
For our PTC air heaters, we also offer a specially adapted range for
small series, with heat outputs of up to 1 kw and especially compact
dimensions. Our PTC heating elements can be controlled without
problem using an existing HVAC control panel, and are particularly
speedy at providing an agreeable temperature in the vehicle, as
they directly heat the ambient air. As in our water heaters, the PTC
technology is totally safe and reliable.
THE ADVANTAGES OF PTC AIR HEATERS AT A GLANCE:
Highly responsive as the air is heated directly
Problem-free integration in existing HVAC systems
Control via directly connected heating circuits
Actuated by simple relays or electronics
High heat output with compact dimensions
Safe and reliable PTC technology

OUR PTC HEATING SYSTEMS – SUITABLE FOR ALL APPLICATIONS
Our specially adapted heating systems for small series are ideal for
use in a diverse range of vehicle categories. As they can easily be
adapted to various requirements and circumstances, they can be used
in the following vehicles, for example:
Electric passenger cars
Electric vans
Electric buses
Electric commercial vehicles
Selection of the right Eberspächer product depends on the type of
drive. In a vehicle with purely electric drive, a high-voltage air heater
is installed in the ventilation system, where it provides rapid heat.
In a hybrid vehicle, we recommend installing a high-voltage water
heater in the coolant circuit.
BIOETHANOL HEATERS – GUARANTEED COMFORT AND RANGE:
Innovative fuel heaters from Eberspächer enable electric vehicles to be heated 100 %
with environmentally friendly bioethanol, without adversely affecting the range. And
Eberspächer bioethanol heaters have a major advantage over other battery-independent
fuel heaters: they are almost completely CO2-neutral. The soot-free combustion of
bioethanol is yet another plus point. Exhaust emissions are considerably reduced and are
around 90 % below legally required levels. what's more, the heater has an extremely
low consumption. while the Hydronic water heater uses the vehicle's existing convector
and air vents, the Airtronic air heater can be integrated almost anywhere. It takes in air
via its own fan, and directly heats the vehicle interior. And electric car drivers no longer need to worry about reaching a service station: as
canisters of bioethanol can be purchased online or in hardware stores, they no longer have to plan refueling stops at service stations.
This makes use of waste heat from the engine for heating, so
improving energy efficiency. The PTC heater is then used as an
additional heat source, or when the vehicle is powered purely by
electricity. Major advantage for water heating: The AC system can
pre-heat the sensitive traction battery in the winter, or keep it cool in
the summer (preconditioning function).
And last but not least, in fuel cell-powered vehicles, the energy
produced for powering up the fuel cell on start-up can be used for
heating.
