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.

18

+

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.

19

+

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.

20

+

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.

21

+

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.

22

+

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.

23

validation of mass scale unit

Equipment • • laboratory precision balance unused filter cartridge selecting the submenu "Mass „ – remove the unused filter Stabilization begins (around 3 minutes) weigh the filter cartridge on a laboratory precision balance, and write down the result Press "Next" when the mass drift progress bar is filled completely green to initiate the zeroing process Mass scale unit must be back in vertical position

validation of mass scale unit

When zeroing has been completed you are prompted to re-insert the filter cartridge – after zeroing!

press “OK” When the lower progress bar is full after approx. 1minute, the graphic displaying the measurement readings is displayed Undo the screw cap, insert the weighed filter cartridge, and then screw the cap back on again It takes at least 2 minutes before the measurement reading can be read and compared with the target mass of the weighed filter cartridge. The maximum deviation from the target mass must not exceed ±5%.
