Truma company history


On returning home after WWII, Philipp Kreis opens a language school in Munich. The lack of mains power in the post-war period poses a major problem for evening courses, giving him the idea of going into gas light production.

Due to the increasing demand for gas lights, Philipp finds himself producing and selling them in large quantities in a very short space of time. On 27 October 1949, he registered his trade under the company name Truma.

The brand name Truma stands for the name of the then US president Harry S. Truman, who the company’s founder Philipp Kreis very much admired due to the instrumental role he played in restoring Germany to an industrial nation.


The first quick-acting valve with diaphragm seal is designed, patented and built.

It is suitable for universal use in applications involving compressed air, gas and many liquids.


Truma-matic is "the first officially recognised caravan heating system”, not reliant on mains electricity, easy to use thanks to a piezo ignition, entirely safe thanks to its enclosed system and thermo-electric safety ignition device, and economical to run thanks to a high-performance burner.

February sees the sale of the 100,000th Truma light and the 500,000th Truma valve.

The company expands, moving into newly built premises in the Berg-am-Laim area of Munich in July.


A new idea sees the development of a new business area: central oil supply for homes. Truma develops the necessary accessories: the Truma two-way valve and the Truma valve socket.


Truma offers a variety of products to provide “the right heater for every caravan”.

Warm air distribution for increased comfort: flexible pipes and infinitely variable outlets enable heat to be distributed in accordance with requirements. Truma supplies the blower for mains or battery operation, along with a complete range of modular accessories.


The Duomatic gas regular is introduced, making the process of changing over from operating cylinders to reserve cylinders fully automatic. The regulator also comes complete with a pressure indicator so that the gas system can be checked for leaks.

The association of caravan and camping journalists (ACJ) presents Truma with the “Caravan mit der goldenen Nase” award, which recognises top-selling products, for inventing the Duomatic.


Truma decides to set up its own mobile customer service organisation to take expert support and advice directly to customers on campsites in Germany – a unique service in the sector.

The TÜV introduces a requirement that caravan gas systems are checked every two years. Truma’s customer service division is responsible for inspections and the issuing of test certificates.


The Trumatic E, an electronically controlled heater, is launched. It can be installed in mobile homes, boats or trucks.


The new Truma Therme brings hot water supplies to caravans and motor homes for the first time. Water is heated by the warm air system in the gas heater.


Truma perfects hot water supplies for caravans and motor homes by developing a gas boiler which makes taking a shower in recreational vehicles possible for the very first time.


Production, engineering and administration are combined on the same site in new modern buildings added to the existing production premises in Putzbrunn. This provides scope for expansion.

This year also sees the introduction of a generously dimensioned cold chamber that is even suitable for large motor homes, providing a location in which Truma can test equipment and vehicles under the harshest of practical conditions. The cold chamber also proves popular with vehicle manufacturers and trade journalists for carrying out a variety of tests.


The daughter of the company’s founder, Renate Schimmer-Wottrich, is taking over the management of the company as managing partner.
Phillip Kreis is withdrawing from the day-to-day running of the business.


The production facilities are modernised. All production processes are optimised and reorganised.


A programme of building modernisation and expansion begins: the kitchens, canteen and training centre become a communications centre and a bridge links the production building to the new distribution warehouse.

State-of-the-art training rooms are installed, so that even more customers now have access to the training Truma has been providing for many years.


The new Trumatic C supplies heat and hot water from a single device, thereby offering freedom and luxury for independent recreational travel. Many manufacturers of motor homes add the Trumatic C as a product feature immediately.


The Truma UK subsidiary is founded for sales and service of Truma products throughout the UK.


The Ultraheat 230 V additional heater, the ideal addition to the Trumatic S gas heater, is launched. The Ultraheat supports three heating modes: heating with gas, heating with gas and electricity or heating with electricity only.


Truma adds manoeuvring systems for caravans to its product portfolio. The original Mover® makes manoeuvring caravans child’s play.

During the course of the same year, an air conditioning system is developed and launched so that comfortable climates can be enjoyed during the summer months also.


Truma opens a new service centre, providing an environment for customer service and service workshop personnel to serve customers’ needs even more effectively.


In building the technology and innovation centre, Truma offers its employees a creative basis for new innovations. New and extraordinary ideas are born in the many new laboratories, two new cold and climate chambers for vehicles, and a state-of-the-art test facility for developing air conditioning systems.

With the introduction of the Saphir compact and Saphir comfort air conditioning systems, Truma brings air conditioning devices to the market which are more lightweight and quieter than any of their predecessors.


The new Saphir vario air conditioning system with power inverter is by far the quietest in its class, providing cooling functions on three levels and suitable for use whilst on the move or stationary at 12 V or 230 V.


Truma launches the Truma Combi, its new heating system for motor homes. Replacing the Trumatic C, of which more than 500,000 units were built, the Combi is more compact and even more lightweight. It also features Frost Control, the first entirely current-free drain valve.

Even before it had its market launch, the new Truma Combi heating system won the reddot design award for 2007. Alongside the Truma Mover® manoeuvring system, the new Truma Combi heater is the second Truma product to enjoy the accolade of the reddot quality seal.

The opening of the company’s Italian subsidiary Truma Italia S.r.l. brings Truma even closer to its customers in the rest of mainland Europe.


Truma joins forces with CALIRA, the leading supplier of power supply equipment and control and display panels for recreational vehicles.

Renate Schimmer-Wottrich is resigning from the management board to take over as chair of the advisory board.

The new Truma Combi D motor home heater sees the addition of a diesel product to the Combi family. The Combi D is the lightest and yet most efficient diesel combination heater on the market.

Truma continues to grow, opening an agency in China so that it has a local base right from the start as the caravanning market takes off in the region.


The new Mover® R manoeuvring systems are introduced, offering yet more power and reliability.


The new gas pressure regulation systems MonoControl CS and DuoControlCS with crash sensor take safety for heating whilst on the move to the next level.

Truma AquaStar for cleaning systems and water is launched: the new Truma AquaStar method of system maintenance poses no risks whatsoever to the environment or health and can be used for simple yet effective cleaning of the drinking water system in any recreational vehicle.


Truma is now advancing into the roof and air conditioning market as it launches the new Aventa Comfort for caravans and motor homes. The Aventa air conditioning system supports not only cooling but also heating, with its energy-saving heat pump. Thanks to its cooling power of 2400 Watts and the extremely flat air distributor in the interior, the Aventa sets new standards among roof air conditioning systems.

The Mover® TE R4 is being introduced. This means that two-axle caravans and trailers up to a total weight of 3000 kg can now also be manoeuvred.


The proven Mover® SR has been completely overhauled. Thanks to its higher output, it can now move caravans weighing up to 2,000 kg. It stands out thanks to its optimised design that now protects the motor and transmission even more effectively against corrosion, oil, salt and wet.


In 2012 Truma celebrated a special anniversary: 50 years of caravan heaters.

The rooftop air conditioning unit Aventa eco is launched. It stands out thanks to a high cooling output of 1,700 Watt and low power consumption. The product also won the Reddot Design Award and the Caravaning Design Award for its appealing modern design in 2012.

The Truma gas filter protects regulators and valves effectively against soiling and oil. A further innovative addition to the gas supply range is the Truma LevelCheck. This device shows the filling level of gas cylinders and uses an ultrasound process to detect whether there is liquid gas in the cylinder at the measuring point. It also won the Caravaning Design Award.

Truma offers two new versions of the legendary S-heater: The S 3004 and S 5004. They not only retain the proven quality features of the predecessor models, but also set new standards in terms of operating convenience, warm air distribution and design.

Truma launches its fuel cell system VeGA. It guarantees a self-sufficient power supply completely independent of the mains supply. The VeGA uses liquid gas to generate energy in an environmentally-compatible and efficient manner, thereby charging the supply batteries. By virtue of its high output power of max. 250 Watt (6,000 Wh a day), the VeGA reliably secures the individual energy requirements.


Truma Geschichte 2013

In 2013 Truma won the innovation prize "Top 100" as one of the most innovative medium-sized companies in Germany.

The Truma SolarSets are launched. They are available in four performance models and guarantee excellent energy efficiency per surface thanks to their mono-crystalline structure.

The new Saphir comfort RC can either cool and dehumidify with 2,400 W or heat with 1,700 W. Despite the new integrated heat pump, it is the smallest under-bench air conditioner of its class.

Truma launches a new digital control panel for its Combi heaters: the CP plus offers much more operating comfort and lots of new functions.

Truma's Mover® XT sets new standards for manoeuvring systems. Thanks to its brushless motors, the XT guarantees unprecedented manoeuvring precision and also saves up to 20 kg in weight. The new Mover® PowerSets with the new lighter Truma BC 10 charger are perfectly matched to the Mover® XT.

Truma continues its internationalisation strategy and founds subsidiaries in the USA and China.
