With over 30 years in business DACS bring to you the highly engineered & energy efficient equipment, which excels in laboratory and field test certificates & data.

Animal Welfare
Animal welfare is becoming a focus point in the retail market. Promoted by supermarket buyers and consumers this continues to become a key point of importance for future growers. The industry players that embrace the growing consumer demands and are then capable of meeting the markets expectations will stay and grow in business.

A perfect climate delivered by DACS systems, will allow animal welfare to be seen in its fullest, as the importance of overall bird health is promoted by clean and fresh air with low to zero foot sore scores and breast burn are eliminated from broiler production.

Climate Control
Climate in the sense of a perfectly controlled shed where temperature and humidity is kept according to required set points. Manual litter control is not only expensive but detrimental to bird health and then becomes a thing of the past with a DACS climate system, which reduces the overall stress on the birds and helps promote top growing conditions and exceptional bird performance.

With dry litter comes low CO2 and NH3. Without a saturation these factors which are often found in traditional systems contributing to a poor environment, enables farm managers and birds to remain in the most comfortable environment and proving ease of management.

DACS has perfected the control of indoor climate without compromising on energy efficiencies.

One unique concept
At first glance there is no visible difference between the three versions of MagFan.
MagFan, MagFan Plus and MagFan ONe all make use of the same housing and impeller. The only differences lies in the motor technology used and the possibility of using different impeller pitch settings.

One unique concept - three different fans.

Without exception, MagFan outperforms all other fans
MagFan is the world leader in fan efficiency. No matter the version you choose they all offer unrivaled performance, efficiency and service life.
MagFan owes its efficiency to much more than just the high efficiency motors. More than anything else, the very pronounced efficiency advantage stems from the aeromechanics applied in the development of MagFan.
This becomes quite evident when comparing capacities and efficiencies against other makes of similar size fans. Without exception, MagFan outperforms all other fans!

Aerodynamics make the difference
First and foremost, remember that a fan with superior aerodynamics will always be the most efficient fan no matter the speed it operates at. So all the way from minimum speed to full speed, the aerodynamics play the most important role in fan performance and efficiency as well as pressure capability (thrust).
More air can be moved with fewer losses. The fan simply consumes less power to maintain the desired flow.

We deliver energy efficient, high performing systems designed to maximize yield and animal welfare, at a fraction of the normal running costs and carbon emissions. Poultry and pig production requires quite a bit of energy, but at DACS we have worked hard to reduce your operating costs to a minimum. We continuously develop products which will help you reach your goal: healthy animals and high outcome.

Focus on energy efficiency
Our philosophy is to maximize energy efficiency, and this is incorporated into everything we do. Thus all our systems are designed to give you the best energy efficiency and the most durable systems on the market. Our focus on energy efficiency means that your initial investments are earned back sooner than normally - and it just might be that in your country you could get a tax deduction because you save energy with our systems.

In the beginning of most production batches, the animals need heat to thrive, and the heaters have to run. Later on the animals produce a lot of heat themselves, and the surplus heat has to be utilized while the ventilation has to remove gazeous waste in order to keep the animals healthy and the litter dry. The surplus heat produced by the animals is a resource, and we use these calories in our ventilation system. 

Corona – an active roof mounted air inlet

The Corona is an active fan assisted air distribution unit. The active distribution of  reheated, oxygen rich air ensures a supreme climate in the house from day one to finish, no matter the outside conditions. By providing ideal airspeed and plenty of oxygen at floor level, the systems support the animals’ metabolism and growth. Tests have shown that by utilizing the warm air in the roof space the Corona typically returns 10kW of heat for each 1kW of electricity used and cuts the overall heat consumption by as much as 50%.

At low ventilation rates, when it is very cold outside and/or when the animals are small, the Corona preheats the air by mixing small portions of cold incoming air with warm room air, before distributing the air evenly throughout the house. The Corona works with partially opened dampers and mixes an increasingly larger portion of incoming, cool air with warm room air, maintaining ideal climate conditions in the house. When temperatures soar, the dampers go to vertical position for maximum airflow. The mixing action is suppressed by the main flow, and air is shot outwards and downwards, creating unsurpassed thermal comfort by means of vertical air movement.  

Market-leading roof mounted exhaust fan
The HE740 is the most efficient roof mounted exhaust fan on the market. The advanced aerodynamics ensure high air exchange rates at very low energy consumption. Trouble-free performance. The advanced chimney design with its expanded core ABS provides good insulation values and serves as a sturdy mounting base which does not flex or expand when exposed to extreme temperatures. The totally corrosion-free unit provides years of trouble-free, efficient operation and 30% lower energy consumption. In direct comparison against leading suppliers, the HE740 exhaust unit offers at least 30% lower energy consumption at equivalent flow rates. 

The HE740 exhaust with butterfly damper completely seals off from rain, birds, insects, rodents and light when not in operation. This unit is for on/off control.

The HE740 with turning baffle is for speed control (0-10 Volt) via a frequency inverter, or via on/off signal.

A house for poultry production is a climate zone where it is crucial to be able to establish and work under conditions which may differ completely from the climate outside. In order to ensure that you have the best conditions to keep the in-house climate then the roof, walls, floors and footing must be properly isolated. It is an absolute necessity that there is a moisture barrier under the floor to keep both floor and footing dry. The moisture barrier makes sure that humidity cannot penetrate the floor, but it is also essential to establish an efficient draining of the entire building land to remove water from the site. If these conditions are fulfilled you can create an optimum climate in the poultry house where your flock will thrive and grow throughout the production period.

The First Days of Production
Before a new flock arrives you need to make sure that the poultry house has been pre-heated to the desired temperature for at least 24 hours – typically 33-34˚C. The reason for this is that the surfaces in the construction need to be as warm as the air in the house. 6-8 hours before the day old chickens arrive, the litter is distributed in the house.

If the surface in the construction is not thoroughly heated it will submit cold to the air inside the poultry house which will have a negative impact on the day-old chickens and on the quality of the litter. The birds will then have a tendency to clump together and they will use unnecessary energy in the attempt to keep warm. This loss of energy results in increased mortality as well as uneven growth.

Furthermore there will be a condensation in the litter, if the floor temperature is significantly lower than the desired temperature when the birds arrive. As a rule of thumb the concrete floor must be at least 28˚C, when a new flock arrives.

For the day-old birds to maximize their genetic growth potential it is important to create a certain movement of air down by the floor already from day one. This subtle movement supplies oxygenous air to the birds and at the same time removes CO2.

As CO2 is approximately 70 % heavier than atmospheric air the concentration of CO2 will rise significantly in the occupied zone if the house is not properly ventilated from day one. Too much CO2 can repress the development of the birds’ lungs and thus reduce their ability to absorb oxygen. The result is reduced metabolism and lowered growth.

Humidity and Temperature
Generally there are a number of physical conditions you have to observe during the production period.

When you want the humidity in the poultry house to be significantly below the humidity in the air that is lead to the poultry house via the ventilation system, it is advisable to limit dehumidification as it is not possible to dehumidify to the wanted level (when it is raining, RH is 100 %).

If you decide to follow the programmed curve for humidity when the RH outside is about 100 %, the climate controller will continue to call for heating in order to dehumidify. This leads to a dramatic increase in heat consumption which in turn increases the need for ventilation as the temperature rises due to the heat added to the house.

The increased ventilation under these conditions may not be suitable in regard to young birds. It may cause draught and can also prompt condensation in the litter. Wet litter increases the production of ammonium. A high level of ammonium gives burnings on the birds’ pads and bodies and generally reduce the welfare of the birds. You spend more money getting lower rent ability. All in all a fool’s bargain!

The above mentioned conditions are depending on circumstances from the outside environment. It’s a physical condition you have to accept and deal with in order to be able to react in due time and avoid the negative consequences by NOT reducing the dehumidification.

DACS’ own ACS6 climate- and production controller has an outdoor humidity sensor. Via measurements from this sensor the ACS6 decides if it is possible to effectively dehumidify the poultry house. If this is not the case dehumidification is automatically reduced in order to avoid the problems mentioned above. DACS is the only company, whose controllers have this functionality.

Recommended Settings
We strongly recommend that you follow the pre-set curve for temperature in the ACS6 climate and production controller as this is the curve recommended by most hatcheries. Yet there might be local variations where it is natural to change the settings. If you choose to deviate from the recommended temperatures it may have negative influence on the welfare of your poultry. If the temperature in the poultry house is lower than the recommended your chickens will have to use unnecessary energy to keep warm. The consequence is a higher FCR.

Generally speaking poultry are too often kept too cold rather than too warm. A common mistake is to lower the temperature in the poultry house to make the chickens eat more. What is often forgotten is that a big part of the extra intake of feed is used to keep up the chickens’ body temperature as the surroundings are actually too cold. And as feed costs are significantly more than fuel it is a misinterpreted strategy to lower the temperature – not to say your profitability.

You also need to pay attention to the fact that there is a close correlation between temperature and humidity in the sense that the total energy in the air is a combination of temperature and RH. Just as we humans feel more uncomfortable in high temperatures and high humidity than in hot, dry weather, so do the chickens experience extra strain when both heat and humidity is high. On the other hand it is obvious that a low humidity will make the birds feel colder than what the thermometer shows. Thus a low humidity must be followed by a higher temperature setting to avoid the animals feeling cold. And visa versa.

In periods with warm weather the humidity of the outside air is often low which means – according to the above mentioned – that the comfort temperature is often higher than the temperature curve indicates. The ACS climate controllers from DACS automatically compensate for these conditions ensuring optimum welfare for the birds under all circumstances. If you do not want this automatic compensation or if you do not have the technical control opportunities, you need to keep a close eye on both temperature and humidity in the poultry house to make sure they match the climate curves for optimum animal welfare.

Focus on energy efficiency
All our systems are designed to give you the best energy efficiency without compromising climate and animal welfare. Our systems will reduce your overall running cost by 40% compared to other systems and still we ensure optimum climate conditions that allow your birds to utilize their full genetic potential.

Savings on your heating bill
The DACS Corona air inlet is the only ventilation unit on the market that utilizes the warm air trapped in the roof space and mixes it with fresh incoming air. This means 40 to 50% savings on your heat bill compared to other systems. In fact the savings means that every time you spend 1 KWh running the ventilation system, you will save 7 kWh worth on your heat bill. On top the Corona creates a uniform air flow pattern throughout the house that bring oxygen to the birds and keep the litter dry.

Keeping track on your production data
Your entire production can be controlled using one of our ACS controllers, which ensures maximum energy efficiency and optimum climate conditions every single day during the production and at the same time keeps track of all relevant parameters - from feed and water consumption to daily growth.
