Mechanical & Thermal Processes

Designed for 85/85 tests
New humidity chamber



Mechanical & Thermal Processes, Pharmaceuticals

From now on, all Memmert HCP humidity chambers are available with the TwinDISPLAY convenience features as standard. A compact 56 litre benchtop model complements the humidity chamber range, first presented at Control 2018 in Stuttgart.

Extensive comfort functions

This high-quality climate chamber is an economical and almost maintenance-free alternative to appliances with active cooling, especially for applications above room temperature such as accelerated service life tests and 85/85 tests. The ControlCOCKPIT touch screen control unit is the HCP’s control centre, where all parameters can be set in three quick steps. Status messages as well as time and alarm messages are also displayed simultaneously. The TwinDISPLAY convenience features also allow communication via modern interfaces and intuitive and simple programming via the control and protocol software AtmoCONTROL. Specially adapted functions such as battery-buffered operating display, SetpointWAIT function for temperature-dependent process runtime, alarm messages via e-mail or SMS and standard feed-throughs on the rear panel support reliable and precise testing processes.

Active humidity control minimises condensation

Like all Memmert climate chambers that operate in the positive temperature range, the humidity chamber HCP also has active humidity control. It guarantees reliable homogeneity of temperature and humidity as well as short recovery times after opening the door. In combination with heating on all six sides, including heated inner glass door, it minimises vaporisation in the interior and thus the risk of condensed water dripping onto the test object.

New gas coolers eliminate thermal problems



The removal of moisture is an essential step in extractive sample gas conditioning systems. However, this process generates excessive heat inside the cabinets and thus very often requires additional efforts like air conditioning.

The new gas cooler series TC- kit (+) from Bühler Technologies eliminates these extra efforts. Peltier elements as temperature transmitter are the middle part of a sandwich consisting of a heat sink with integrated fan forming the outer part and a cooling block with exchangeable heat exchangers and the attached electrical terminals as the inner part. For the installation a cut out has to be made at the appropriate side wall of the cabinet.

With the heat sink geometrically larger as the internal parts, the unit slides into the cut out and finally is attached to the outside wall of the cabinet and sealed by a gasket. The electrical leads and the sample gas lines are kept inside the cabinet whereas the thermal load is dissipating to the ambient keeping the inside of the cabinet considerably cooler.

The protection class of the mounted unit is IP 54.

The TC Kit (+) requires 24VDC as power supply. As an option an extension unit for 115/ 230V AC supply is available and will be saddled directly to the basic unit. This extension also provides all neccessary connections to auxilliary units like sample gas and condensate pumps as well as moisture detectors and heated sample lines.

The operation parameters and alarm settings are programmable by a remote controller with digital display. This controller can be installed at an appropriate place inside the conditioning cabinet. The TC Kit+ version comprises special heat exchangers with minimised wash out effect as required by EN 15267-4 suitable for automated emission monitoring (AMS) systems.

Bottrop pump specialist is now the holder of the TOP 100 seal for exemplary innovation management



“All things flow” – standing still is not an option: At SEEPEX, one of the world’s leading manufacturers of progressive cavity pumps, the company claim goes far beyond the manufacture of first-class high-tech pumps. With new developments such as the holistic “Digital Solutions” concept, the medium-sized company is leading the classical field of mechanical engineering into the future in a targeted manner. Now the Bottrop-based specialist can officially count itself among the nationwide innovation elite. On June 19, SEEPEX was awarded the “Top 100 Seal” for exemplary innovation management and above-average innovation successes.

In Bottrop, the “InnovationCity Ruhr”, future-oriented ideas and solutions have been developed for the past ten years with the aim to meet the challenges of climate and structural change in urban areas. And there are also companies that have successfully and for a long time already been contributing to such innovations at the heart of the Ruhr area. For almost 50 years, the family company SEEPEX in Bottrop has been developing and building progressive cavity pumps, macerators and control systems. The manufacturer has continuously developed its pumps further and introduced new pump technologies in order to constantly improve its own products and, for example, enable easy maintenance. Digital solutions for the control and monitoring of pumps have long been offering great added value; in most cases, these are developed together with key customers and tailored to their individual needs. The SEEPEX management has risen to the challenge of digital change at an early stage. In the segment of progressive cavity pumps, which conveys ‘delicate cargo’ such as raspberries just as gently as thick chunks of sewage sludge in the environmental technology sector, the company plays a pioneering role within the international industry with its “Digital Solutions”. The holistic concept offers a portfolio of mobile and networked services, ranging from digitally supported maintenance of the pump using virtual reality, through digital pump management with simple spare parts ordering, to data-based services.

80 percent of SEEPEX products are exported worldwide. The company, which was founded in 1972, now has 18 subsidiaries and branches outside Germany, as well as distribution centers in over 70 countries. There are more than 800 employees worldwide, 423 of whom work at the company headquarters in Bottrop. This is also where the heart beats for new ideas.

For the top innovator, digitalization is the most important innovation of the past few years. Pumps can now be monitored in real time. With the SEEPEX tools, maintenance can be carried out partly by the customers themselves and even remotely. This means that customers can access, control and monitor the pumps with a mobile phone or tablet. The measured values are loaded into a cloud where they can be analyzed by customers or by SEEPEX. An internal team of data analysts deals with data mining and anomaly detection. This saves time and costs and also secures production, as malfunctions can be avoided.

In Bottrop, a dozen employees consistently oversee the digital change, while the management commits a large amount of time towards pushing innovations forward. Every year, around 200 suggestions for improvement are received from the workforce, two-thirds of which can generally be implemented. Between 2016 and 2018 alone, SEEPEX was granted 13 patents at both national and international level, plus certificates attesting to the pumps’ highest standards. For example, they meet the highest hygiene standards in the food sector and are certified according to EHEDG. Even the iF Design Award for innovative industrial design has already been awarded to the SEEPEX technology SCT because besides all of its functionality, easy handling is also to the fore.

All this and much more impressed the jury of the TOP 100 competition, which was held for the 27th time this year. Innovation researcher Prof. Dr. Nikolaus Franke from the University of Vienna and his team tested around 120 parameters for the selection of the top companies on the basis of a scientific system. Here, SEEPEX was easily able to maintain its position in the league of the most innovative German medium-sized companies according to the strict criteria. An award ceremony with the mentor, science journalist Ranga Yogeshwar, has had to be cancelled this time due to the corona restrictions. In Bottrop, the management and staff are nevertheless very happy: “The same passion with which we have been working continuously for almost 50 years on the technical side to create top products also drives us to work together continuously on the future. We are proud that SEEPEX is now one of the TOP 100,” says owner and CEO Ulli Seeberger.

“Innovative medium-sized companies like SEEPEX GmbH from Bottrop are not afraid of change, but see it as an opportunity. In the scientific selection process, the company impressed in the largest size category (companies with more than 200 employees) especially in the categories of “External Orientation / Open Innovation” and “Innovative Processes and Organization” according to the competition initiators. They were particularly impressed by the way the company works on new products and services: Innovations are created in a close exchange with the customers. Innovations are developed step by step and tested with the most important customers (“lead users”). “Only when the customer successfully benefits from the added value is further development – or adaptation – carried out,” is how SEEPEX CTO Dr. Christian Hansen explains the procedure. “It is not uncommon for us to discover potential for improvement among the customer’s processes as well – for us, this is an important approach and confirmation that we can provide our customers with greater support in this respect.”

Since 1993, compamedia has been awarding the TOP 100 seal of approval for special innovative strength and above-average innovation successes to small and medium-sized companies. Since 2002, the scientific management has been in the hands of Prof. Dr. Nikolaus Franke. Franke is the founder and director of the Institute for Entrepreneurship and Innovation at the Vienna University of Economics and Business Administration. The mentor of TOP 100 is the science journalist Ranga Yogeshwar. Project partners are the Fraunhofer Society for the Promotion of Applied Research and the German Association for Small and Medium-sized Businesses (BVMW). As media partners, manager magazin, impulse and W&V provide advice and support for the company comparison. More information is available at
