Shelves „made by HOF“
The shelves of a freeze-drying system are elementary components and thus essential part of the whole process. In order to meet its own requirements, “in-house” manufactured shelves for HOF freeze-drying systems are produced in the own shelf production department.
The shelves of a freeze-drying system are elementary components and thus essential part of the whole process.
Accordingly, HOF has put its focus on the shelves manufacturing. In order to meet its own requirements, “in-house” manufactured shelves for HOF freeze-drying systems are produced in the own shelf production department.
Certified welders and a redundant structure of the manufacturing machines ensure the required quality. In addition, the proven design ensures a homogeneous temperature distribution, regardless of whether there are shelves with 0,075 m2 for a laboratory equipment, or shelves with individual sizes of 2,8 m2 for a production plant .
According to the special machinery construction, each shelf package is individually designed following the customer demand and the respective available area. All production steps proceed following a specified guideline in order to keep a consistent quality. Controls of shelf welding seams in water bath and a measurement of the shelf areas with laser technology are here basically performed. Grinding operations are accurately monitored and the roughness is recorded. If necessary, X-ray tests or thermographic recordings of individual shelf areas can be carried out.
The 1st HOF technical forum –<br />a reflection with information and impressions

In 2015, the guaranteed availability of spare parts for Siemens S5 components will discontinue, for the components of the S5-135U series too.
From now on, we cannot ensure the supply of computer hardware for Lyocom I and II systems anymore. Therefore, since the company HOF can no longer ensure the availability of the spare parts, we now announce the termination of the support for the SCADA systems Lyocom I + II with effect from 31st of December 2015. This means that any changes to do at the systems after this date are then only possible in exceptional cases. In each individual case, it will be checked whether defective systems can be repaired or not. We will be glad to assist you in developing a concept for the migration of the system control.
Energy independence by means of own soft commodities
Current discussions about renewable energies reported in the daily media are also an important issue for our company. Expenses for electricity and heat for an office and production area of over 12,500 m² are considerable.
Current discussions about renewable energies reported in the daily media are also an important issue for our company. Expenses for electricity and heat for an office and production area of over 12,500 m² are considerable. Since sustainability is top priority in our corporate philosophy, HOF has been using a technology since the beginning of this heating season, so far unique in Germany. The company owner and hobby farmer Hans -Georg Hof is a pioneer in concluding the entire value chain by working straw into combustible to generate its own heat supply.
The straw-by product resulting from the cultivation of grain is worked into straw pellets during a complicated procedure in the family-owned pellet plant. The pellets are then burned in the special biomass boiler for CO2 neutral heat production. The ash obtained by burning is then further of use as an excellent fertilizer for agricultural areas.
The heating system itself has a modular design consisting of five 20 ft containers.
It is composed of the burning boiler with control system, the pellet storage on top, the laterally connected unit for flue gas cleaning and two large-sized buffers for heating water.
By means of this system, it was so far possible to heat successfully the 5,700 m² large part of the factory in Gladenbach-Mornshausen. The straw needed for this procedure is covered at 100 % by the family’s agricultural land. The pellet plant is operated thanks to a photovoltaic system installed in sufficient dimension, so that even the production of pellets happens in a self-sufficient way.
This newly established innovation is already widely approved and HOF is pleased to make this contribution to sustainability.

New CD for HOF-Prüfsysteme
The relaunch of a corporate design (CD) is subject to, as is every other type of advertising in the market, the spirit of the time since viewing habits change and reflect the image of a company. During the course of the relaunch of the CD for HOF-Prüfsysteme, the company logo was first reworked based on the company colors. The communicative effect of the company logo should convey a high-quality impression and the reliability, competence, and creativity of the company and the reference to technology should be expressed graphically.
Relaunch of the company logo and the company configuration
The relaunch of a corporate design (CD) is subject to, as is every other type of advertising in the market, the spirit of the time since viewing habits change and reflect the image of a company. During the course of the relaunch of the CD for HOF-Prüfsysteme, the company logo was first reworked based on the company colors. The communicative effect of the company logo should convey a high-quality impression and the reliability, competence, and creativity of the company and the reference to technology should be expressed graphically.
After the relaunch of the company logo, the company configuration as well as the image brochure will be adapted to the new image under consideration of the factors mentioned above. The development of HOF-Prüfsysteme’s Internet presence was based on the new CD.
The Internet Presence of HOF Prüfsysteme
The most important goal concerning the Internet presence of HOF-Prüfsysteme GmbH was to first ensure that it is optimally structured for usability and that these principles are implemented. In order to cope with high communicative demands, the pages were, among other things, positioned with portrait orientation. HOF is constantly growing and therefore requires sufficient space for communications. The portrait orientation offers HOF the opportunity to configure its Internet presence in a very client-oriented way in order to respond to the special needs of users.
Another important goal for the Internet presence was to emphasize the company’s depiction of itself in addition to featuring clear and appealing visual aspects and giving consideration to the information desired by clients. The fresh breeze through Web 2.0 with the ideas it brings should make itself known in this area.
Content is comprehensively and meaningfully formulated and the navigation paths are set up according to content in consideration of logical factors so that users can find the desired information quickly with only a few clicks. In order to optically support this, the navigation technique will be adapted accordingly.
The established base colors are the company colors of green and blue with gray tones and these project the overall impression in terms of color. The arrangement of content as relates to font size and typography are to remain very user-oriented. Different information will be packed into boxes with various different formatting, the so-called “header boxes” that support improved differentiation and perception of information.
Expansion of the HOF orbital department
Ever-increasing demands and quality requirements for transport lines of high purity media resulted in an expansion of the orbital department at HOF site.
Ever-increasing demands and quality requirements for transport lines of high purity media resulted in an expansion of the orbital department at HOF site. An opportunity was taken to restructure the production hall and expand the orbital department along with additional staff and new construction equipment.
The advanced manufacturing will ensure short reaction times for special cases. Furthermore, the stock of the required materials has been adjusted accordingly. The production hall of the orbital department now allows for large set-ups with pipe segments of up to 12m to be fabricated.
HOF further increased its high standards in weld quality and cleanliness to meet specific demands of large projects.
Energy-efficient transport of deep cooled diathermic liquids
Customized installations often require the separation of refrigeration systems from the processing equipment. Along with increasing distances, storage and transfer requirements of diathermic liquids are accordingly effected by losses due to increased heat intakes and ultimately influencing the efficiency of the freeze drying process.
Customized installations often require the separation of refrigeration systems from the processing equipment. Along with increasing distances, storage and transfer requirements of diathermic liquids are accordingly effected by losses due to increased heat intakes and ultimately influencing the efficiency of the freeze drying process. Therefore, highly efficient heat transfer lines are the answer to increasing demands.
HOF performed specific engineering and done development work for these enhanced requirements and extended its construction capabilities after a test phase. New systems are based on high-vacuum-insulated double pipes up to a nominal diameter of DN100. Those transfer lines are pre-fabricated at the HOF workshop and installed at customer’s sites in its final configuration.
This technology offers best possible long-term insulation and is setting new milestones in the market. The lines are completely executed from stainless steel and permanently leak-tight. All welds are performed in high-quality orbital welding technology. The manufacturing process is regularly documented and quality controlled, as in all production areas, ensuring the overall quality in the manufacturing process.
The design is available for heat transfer systems in the temperature range from -100 ° C up to +130 ° C, thus covering all current applications of heat transfer systems utilized for Freeze Drying Systems.
