Omnivent types of ventilation:
Bulk storage ventilation
This type of ventilation is suitable for product storage in bulk with a pile height of 3 to 6 meters. It works through forced ventilation via ventilation ducts or grid floor.
Advantages:
- Forced ventilation and a perfect air distribution with a perfect mixed-air regulation
- Optimal use of the available space
- Easy intake and outtake of product
- Simple loading and unloading of the store
- Low investment per ton of product

Room ventilation system
For storing the product in boxes at a specific temperature, in stacks of approximately 7,5 meters high. The ventilation takes place by a natural airflow around the boxes.
Advantages:
- Clever design with integrated air mix construction
- User-friendly and flexible in use
- Easy installation
- Can be combined with refrigeration
- Relatively low investment for a box storage

Omnivent room ventilation system
Suction ventilation system
With this system, you will have forced ventilation of the product in open boxes, stacked up to approximately 7,5 meters high. Due to the underpressure which is created between two rows of boxes, the air is pulled through the boxes in a forced manner.
Advantages:
- High-quality construction with a perfect air-technological design
- Forced ventilation up to a length of approximately 25 meters
- Excellent air distribution and perfect drying characteristics
- Minimized running hours

Drying wall
Forced ventilation of products in open or closed boxes up to approximately 7.5 meters high. Pallet openings ventilate a row of boxes per layer. Because of the oblique wall construction, the air distribution is optimized.
Advantages:
- High level of flexibility
- Ventilation is possible per row and per layer
- Ventilation capacity at selective pallet opening
- Perfect drying characteristics and air distribution
- Especially suitable when there is a lot of diversity in the product

Omnicuro
This innovative Omnivent storage automation product can be summarized in three words: simple, smart, and yield-oriented.

Omnivent OmniCuro display
OmniCuro is operated using a high-quality touchscreen and is made from high-quality materials. Naturally, OmniCuro can be accessed worldwide from a tablet, smartphone, or PC. OmniCuro is clear and unambiguous right from the first screen, and menu navigation is intuitive. Key data can be viewed quickly and clearly via a series of logical actions.

Omnivent OmniCuro Screen
Based on location-specific parameters, the situation, and factors such as expected weather conditions, OmniCuro recommends suitable storage facility settings. If the user chooses to accept the recommended settings, they can be implemented by way of one simple action. Most of these recommendations are generated automatically by wizards and provide support for
energy-aware storage.
Fans
OmniFans are developed in-house, especially for the application of drying and storing agricultural products.
It has an excellent performance in terms of:
- Efficiency
- Capacity
- Noise

Omnivent Fans – Frequency control for fans
When equipped with the optional frequency control the performance of the fans can be optimized by ventilating at lower frequencies, reducing both energy use and noise.
Humidification
When the humidity of the ventilation air is kept high, the potatoes keep their weight and produce quality. For this purpose, Omnivent offers the OmniPad, which is deployed worldwide to ensure perfect product quality.

Omnivent Humidification
The benefits in a nutshell:
- OmniPad limits weight loss
- OmniPad maintains product quality
- OmniPad has a cooling effect
- No free water drops in the air
OmniBreeze
The OmniBreeze evaporates water into the air, to control the relative air humidity in the store. It can easily be integrated into the store, either by stacking it on top of the boxes or placed on top of the ventilation system.
The OmniBreeze has 2 types:
- The standard OmniBreeze can humidify up to 1000 tons of potatoes
- The OmniBreeze Compact humidifies up to 500 tons of potatoes

CO2 extraction
The CO2 extraction takes care of daily CO2 extraction from the store and air refreshment with outside air. It will keep the CO2 level at a modest level, and maintain the potato quality, and in particular, the frying color for maintaining outside air is absolutely necessary. Too high concentrations can suffocate the potatoes, and negatively influence their frying color.
Advantages of CO2 extraction system:
- Reduced energy use for CO2 refreshment (only a small fan, instead of system fans)
- CO2 refreshment no longer affects the temperature and humidity in your store
- Less running hours of system fans lead to less dehydration, meaning: less weight loss
OmniRecup
The OmniRecup is a CO2 extractor with a heat exchanger unit. The inbound hot outside air is cooled using the cool, outbound air from the store that is with CO2.
Especially in hot and humid climate zones less weight loss and less condensation are the two main advantages.
OmniFrigo
Turnkey cooling solutions with minimum installation costs.
The OmniFrigo unit is completely built and tested in the factory, which makes it very easy to install locally.

Some of the benefits are:
- A high degree of reliability thanks to the use of two independent
cooling circuits - Efficient cooling using outside air if conditions are right
- Minimum drying thanks to the large distance between the lamellas and large evaporation surface
- Can be connected to all climate control computers
- Electrical defrosting of the evaporators
