1. WE ALREADY HAVE A COOLING COIL IN OUR VENTILATION SYSTEM, IN WHAT WAY DOES YOUR SOLUTION DIFFERENTIATE?

You may have noticed that despite having a cooling coil in your production areas condensation, and its impending risks, are still an issue, or that your drying times after cleaning are too long. Cooling coils generally work better in warmer, more humid conditions as their effectiveness to extract moisture from the air decreases the colder and drier the air gets. At 0°C ice begins to form on the cooling surfaces of condensation driers and even getting to such low temperatures requires large amounts of energy for this dry-air solution.

If your food or beverage production operates in an environment below 15°C or you wish to reach a dew point of around 5°C using a cooling coil is not only ineffective but also cost-intensive. Cotes adsorption dehumidifiers can reach dew point temperatures far below 0°C in a steady and controlled manner. This will help you save on drying time and energy-efficiency as well as maintain a high-quality standard. Feel free to have a closer look at the functionality and benefits of our dry-air solution.

2. WHAT ABOUT THE RISK OF AIR POLLUTION?

Air infiltration and contamination are wide-spread concerns for production in colder climates as in the food and beverage industry. The former causes issues for unregulated humidity levels and increased condensation and those compromised production environments can create even bigger issues for the sanitary conditions of food and beverage production if the product is contaminated through air circulation. Both concerns cannot be avoided completely, but they can be successfully managed with an adsorption dehumidifier.

To protect your production environment and produce as well as the dehumidifier itself we offer filters in various classifications and density that can be installed to filter the air coming in and out of the machine. Additionally, each part of a Cotes dehumidifier rotor is heated up to 120°C 5 to 8 times each hour, to avoid any risk of contamination of the processed air. The right filter for your production is dependent on your exact requirements and measurements that our experts can guide you through upon interest. For specific purposes, we can even supply a filter that prohibits viruses and bacteria to pass.

3. ARE ADSORPTION DEHUMIDIFIERS NOT EXPENSIVE IN ENERGY IN ENERGY COSTS?

Cotes dehumidifiers are better suited for production in colder climates because of the innovative, energy-saving adsorption technology. As previously mentioned in the comparison to cooling coils Cotes machines are cheaper for your food and beverage production not despite but because of adsorption. Furthermore, by offering customisable dehumidifiers that can easily adapt to your production needs and be incorporated into existing energy systems, by, for example, repurposing waste heat from elsewhere in your facility as an energy source, our adsorption dehumidifier integrates into your production with a very low environmental impact.

The built-in PLC controller works with a dew point and humidity sensor that ensure your machine runs on minimimun capacity to adapt to your humidity load as needed. An energy-saving programme can, moreover, adjust the heating of the regeneration air flow and overall air capacity to have the lowest possible energy consumption. On top of that, our innovative three rotor models generally draw much of their required energy from low exergy, and therefore cheaper sources, like solar panels or other low-cost thermal inputs which substantially reduces energy costs. The set up also allows our dehumidifiers to be more efficient with regards to how much of that energy they need to create the desired effect, which bodes well for your overall energy consumption.

An estimation of the energy costs for your production can be supplied upon request based on your specific requirements and metrological weather data, but you can get a better idea of the energy savings attributed to our adsorption technology from the calculations from the lithium industry.

4. WHAT ABOUT THE CLEANING AGENTS THAT WE USE DURING CLEANING, WILL IT BE HARMFUL TO THE UNIT?

The casing of the Cotes dehumidifier is as standard delivered in DIN 1.4301 (AISI 304) thus it can withstand the humid environment in any food or beverage production facilities. However, our experts have a few tips for you to ensure smooth processes in your production and your dehumidifier: 

  • Avoid harsh cleaning agents in direct contact with or close to the machine, as well as the steam and gasses in the air from cleaning processes. Ideally, you can install your dehumidifer in a “technical room” with other important equipment to keep it close to the production site but isolated from regular cleaning activities 
  • If you have a small system, run your dehumidier after cleaning, not during
  • if you have a large system, you can run it with 100% fresh air that is blown into the production area during cleaning. When the room is dried you can return back to recirculated air (using a filter) which will have a positive effect on your drying times
  • As a rule of thumb; check and change your filters at least once a year depending on your production and environment

5. WHY DO WE ONLY SEE PROBLEMS WITH CONDENSATION IN THE SUMMERTIME?

In the summertime, the temperature outside is higher, thus the air will contain more humidity. The interaction between that warmer air and the colder surfaces and lower dew point temperatures in your production will lead to higher levels of condensation and therefore an increase in condensation-related problems. The same phenomenon occurs all year round but to a much smaller extent. Using a dehumidifier is the only way to solve this problem long-term and create a room atmosphere that is ideal for your prodocution needs, regardless of what is going on outside.

To better understand the threat of humidity, have a look at our humidity overview that breaks down the phenomenon in general but also especially the relevance it has for your production.
