+ THE MEASURE OF TECHNOLOGY „In close cooperation with our customers we develop, produce and market inspection and cleaning technology that provide tailor-made solutions for heating, ventilation and building applications. “ 13

+ DEVELOPMENT Our innovations set the standards the market follows. Our successful innovations are based on four rock-solid foundations: Our fascination with technology, all of our development engineers have a university degree, our many years of experience and we never stop talking with our customers. 14

PRODUCTION Expert workmanship is required to implement innovative developments. The reason: Wöhler gives top priority to the reliability and high standards of quality of its products. Alone the precision and efficiency of working procedures during production ensure we are able to deliver "the measure of technology". 15 +

+ CONSULTATION/SALES We offer customers planning investments all the support we can give based on our experience and technological know-how. Because development, production and marketing are all under the same roof at Wöhler we are able to call on a great deal of competence. This enables us to offer our customers the best possible solutions to support them during their work. 16

+ SERVICE We focus on providing competent service, because professional equipment maintenance helps to safeguard customer investments. As the manufacturer Wöhler is able to offer absolutely reliable maintenance, inspection and calibration services at all times. 17

FLUE GAS ANALYSIS Precision flue gas analyzers are indispensable to ensure compliance with statutory regulations and resolute environmental protection. Data processing functionality as well as interfaces to a PC and mobile terminal device support the user when evaluating and documenting measurement data.

MEASURING PARTICULATE MATTER Innovative Wöhler products are causing a stir in the industry: Back in 2012 the Wöhler SM 500 was the first particulate matter analyzer to fulfill the more stringent requirements imposed by the first German Federal Immission Control Act (1. BImSchV) with regard to particulate matter limits.

20 + HEATING SYSTEMS Wöhler pressure measurement and leakage detection devices make it possible to reliably monitor systems critical to safety in accordance with (German) technical rules for gas installations; as a consequence, they help to detect and avert hazardous situations endangering the lives of residents.

21 + VENTILATION/BUILDING Objective assessments based on measurement results create transparency and provide a solid basis for making suggestions for improvements. Utilizing Wöhler measurement technology it is possible to set-up ventilation and air-conditioning systems to operate at the best-possible level of efficiency and to monitor their long-term performance.

22 + INSPECTION TECHNOLOGY When chimneys, waste water pipes, flue gas and ventilation systems or industrial facilities need inspecting video inspection systems from Wöhler keep you in the picture. High-quality technology, for example the pan&tilt color camera head, ensure you can see as clear as a bell even in the most inaccessible of places.

CLEANING TECHNOLOGY We develop mechanical cleaning devices for tradespeople and industry to clean flue gas systems and ventilation lines. Cleaning heads made of different materials and strengths guarantee on-the-job satisfaction.

24 Quality- and environmental awareness ECO-PROFIT Wöhler is a participant in the project ECO-PROFIT run by the district of Paderborn with the objective of pursuing ecological and economical concepts. CUSTOMER SATISFACTION At Wöhler we enjoy excellent relationships with our customers. A fact confirmed by TUV NORD. SERVICE-QUALITY Beginning with the initial contact through to our after-sales customer care TUV NORD has confirmed the quality of our excellent service.

Untertit + WÖHLER INSTITUTE OF TECHNOLOGY As a manufacturer we are not only able to draw on many years of experience and offer high levels of expertise, we are always right up-to- date with relevant laws and standards. At the Wöhler Institute of Technology we pass on our comprehensive knowledge to the customer. 25

Untertitl 26 + WÖHLER POWER PARTNER The idea behind the Wöhler Power Partner program is quite simple: We wish to support our market partners operating in the chimney sweep, sanitation, heating and climate control trades to the best of our ability as they go about their daily work. To achieve this objective, we have developed a well-thought through program to ensure our customers receive the best support possible.

+ INNOVATIONS-FORUM Dialog with the customer forms the basis for planning, developing and optimizing our products. That´s why we not only take every available opportunity to talk with our customers, we also create the opportunities too: The innovations forum to be held in Fulda, from the th May 2015 not only offers customers unparalleled experiences, it also offers the place where essential knowledge is passed on. 27

+ WÖHLER THE EMPLOYER We also strive for first class quality amongst ourselves. We wish to achieve the goals we set ourselves – and we do it by working in partnership with one another. A continuously increasing number of colleagues feel at ease at their place of work and in the Wöhler environment. 28
