Bedbugs: Way of life, distribution and control
A topic that everyone is currently talking about: Cimex lectularius, colloquially better known as bedbugs. These are parasitic insects that feed on human blood. In many parts of the world, bedbugs have become a growing threat – a rapid spread can be observed not only in France at present.
Electrolysers – the climate-neutral technology of the future
Green hydrogen is becoming increasingly significant in the field of renewable energy. A recent study by the management consultancy Roland Berger, for example, predicts that European demand for hydrogen will be around 45 million tonnes by 2050.
Why powerful cooling is essential in battery containers
The share of electricity generated from renewable resources is growing steadily - especially in the European Union. However, since sun and wind are not permanently available, the challenge lies in balancing out the natural fluctuations in electricity output. The remedy is connected batteries with associated cooling.
Requirements for water-cooled chillers for use in heavy industry
Due to advances in automation and constant increases in computing power, proper cooling of electrical systems is critical for reliable 24/7 operation. For this purpose, heavy industries can benefit from a coolant that they already use in large quantities – river or brackish water.
Reduce the need for artificial snowmaking with snow cooling units
Artificial snow sysems secure economic viability in many ski regions. At the same time, they attract criticism due to their high water and energy requirements. Snow cooling units offer operators the chance to reduce their artificial snow requirements while saving costs and resources.
How air purifiers can contribute to improving health protection
The question of whether or not mobile air purifiers reduce the risk of viral disease and can help to improve health protection can be answered with a ‘yes’. That is what the current study by the Institute of Fluid Mechanics and Aerodynamics at Universität der Bundeswehr München has found.
Why room air hygiene should also be given priority after Corona
The Corona pandemic has abruptly brought home to us how air in indoor spaces is often contaminated and dangerous to health. Air purifiers protect us from viruses, fine dust, mould spores and other airborne contaminants that will continue to affect our health and well-being after the current pandemic has been contained.
HEPA Filters: Using physical tricks to capture particles
HEPA filters are among the most efficient mechanical filters and remove up to 99.995% of contaminants from the air. They rely on the movement characteristics of different small particles to do so. Based on standardised filter classes, inefficient HEPA filters are easily distinguished from HEPA filters that are actually effective.
Correctly positioned air purifiers complement regular airing
The viral load of indoor air can be significantly reduced by regular airing combined with the use of air purifiers. These also make it possible to remove coronaviruses, fine dusts, and bacteria, even in rooms without windows, and in crane driver cabs. In order to achieve an even distribution of purified air, some rules should be observed when setting up an air filter device.
Powerful, thorough, quiet: How do air purifiers work?
The filter and fan of an air purifier determine the type and quantity of pollutants it can remove from the room air. Other features such as noise emissions provide information about the locations for which an air filter device is suitable.
Why winter is favourable to coronavirus and weakens the immune system
Many types of viruses thrive in favourable conditions in winter. They can survive for long periods in the dry, cold air, and people spend more time indoors. On the other hand, our immune system weakens due to the dry air and lack of sunshine. This combination makes coronavirus and other pathogens more dangerous in winter than in summer. However, humidifiers and air purifiers can help to keep us healthy throughout the cold months.
Deadly for pests, harmless to humans and the environment
While pests in private households are often only seen as a nuisance, an infestation can have serious consequences for companies. Sectors such as the food-processing industry, mills, bakeries and the hotel industry therefore rely on effective control measures. Heat treatment is a form of ecological pest control that does not use insecticides and makes use of biological protein coagulation.
Ensuring food hygiene without insecticides
Food-processing factories have to meet the highest hygiene requirements, but are also an ideal habitat for storage pests. An infestation can have serious consequences for companies, up to and including the closure of operations. Heat treatment is particularly suitable for the food-processing industry, bakeries and mills, as it is a chemical- and residue-free process. Hotels also use heat treatment to combat bedbugs.
Keeping a watch-out for bedbugs so that your guests will not need to
In tourist accommodation such as hotels, youth hostels, or holiday homes, pests come and go with the guests too. In particular, bedbugs spread quickly in such places, and annoy guests in the long term. Using thermal pest control to treat a room is suitable for hotels, as it does not use insecticides and guests in other rooms are not disturbed.
Performing heat treatment while protecting material
Hours of exposure to heat reliably kills storage and food pests, but also puts a strain on the rooms being treated. If performed correctly, however, heat treatment is possible without any damage to the building. Preparing the room also ensures that the entire pest population is killed off without damaging any objects.
How hay quality affects animal health
Anyone who keeps farm animals knows the relationship between good hay and general animal health. Good hay stimulates ruminant animals, e.g., cows and goats to ruminate. It promotes grazing behaviour with the rumen, prevents metabolic diseases, and has a positive effect on milk yield and quality.
Quality in quantity – professional hay and plant drying
Good hay quality is no coincidence, rather it comes from making the right decisions. There are clear definitions and guidelines that go into evaluating hay quality. We cannot influence weather conditions, so the use of a technical hay drying plant is nowadays indispensable for a high quality hay yield.
Designed to meet requirements as the basis for economical hay drying
Hay drying plants can be integrated into new buildings as well as into existing barns. In order for farmers to fully exploit the advantages of effective and at the same time energy-efficient hay drying, numerous individual factors must be taken into account when designing the plant.
Technical hay drying and its advantages
Better planning and quality assurance, more flexibility, independence from weather conditions, less risk of fire, and increased profitability: There are numerous reasons why farmers and operating companies invest in ultra-modern technical hay drying plants, with heat pump, and air dehumidifier.
Planning, installation and maintenance of crane air conditioning units
Careful planning creates the basis for a crane air-conditioning unit that meets the application-specific requirements in the best possible way. A predictive installation and regular maintenance ensure that the air conditioning unit cools, heats, dehumidifies and filters reliably even under extreme conditions.
Industry specific requirements for crane air conditioning units
Crane air conditioning units are used in a wide range of industries that have a variety of requirements in terms of functionality and resistance to environmental influences. Design adaptations ensure that the units function reliably even in challenging environments.
Functionality and design of crane air conditioning units
Safety refrigerants are used in crane air conditioning units to ensure safe operation. Additional components expand the air conditioning systems, e.g. with heating and filter functions. Despite their basically similar design, crane air conditioning units can be divided into compact and split units.
Combining grain coolers for a flexible solution
Operators of a grain storage facility with a capacity of 76.000 tonnes are looking for a cooling solution that works independently from the weather. A combination of one permanently installed central GRANIFRIGOR™ cooler and two mobile units proves to be a flexible solution that meets all requirements.
Safe storage conditions no matter the weather
A storage facility from the 1970s was designed for ambient ventilation. The switch to a GRANIFRIGOR™ KK 280 AHY allows for precise cooling in all weather conditions. The new cooling solution also eliminates silo condensation problems and prolongs the storage duration of malting barley.
Commissioning and maintenance of grain cooling devices
With the new fully automated controller from FrigorTec, the grain cooling unit operates fully automatically. In addition to correct commissioning and settings, careful maintenance is essential for the best possible cooling performance. We describe these and other aspects clearly in our videos.
How you protect your grain from fungi and pests
The infestation of the grain with pests and the development of secondary fungi must be prevented. It is therefore all the more important to create suboptimal conditions for insect pests and moulds during storage, thereby reducing the risk of spoiling of the grain to a minimum.
The best cooling strategy for your grain storage method
Grain can be cold-stored in both floor-level stores and silos. However cooling of the loose grain requires professional air distribution. The grain cooler must also be selected according to requirements. The fully automated control then frees up time for other activities.
When a crane air conditioning unit is necessary
Depending on the location, air pollution and extreme temperatures present challenges for operating personnel and crane electronics. Controlled air-conditioning of crane cabins, electrical rooms, electronic containers and switch cabinets is therefore indispensable in many applications.
