09/13 Efficiency of heat * * ' recovery under practical conditions Earny 2 heat exchanger saves heating costs, improves the climate and reduces emissions in poultry houses

The innovative heat exchanger: good for the birds and the environment This means: eating cost savings of up to 60 per cent; h n improved house climate; a reduced emissions. Earny 2 is available in four sizes, depending on the number of birds in the house. Let the Big Dutchman experts advise you in detail which heat exchanger best fits your poultry house. are cleaned ➃ by means of compressed air, preventing loss of performance by the heat exchanger during the batch. The fresh air is also filtered ➄ to stop dust and leaves from entering the heat exchanger. The warmed fresh air flows from the exchanger...

Filter unit and cleaning Up to six large filter cartridges (max. 64.8 m2) clean the exhaust air before it flows through the exchanger element. These filters remove up to 99 per cent of dust! The filter cartridges are cleaned fully automatically at set intervals. This means: – clean exhaust air from the house – constant heat recovery Filter unit Exchanger element The exchanger element is made of aluminium and has a ruffled structure to ensure a high thermal conductivity. A special coating protects against corrosion and guarantees a long service life. Exchanger element Heater battery and compressor...

Options for air distribution inside the house Depending on the house’s ceiling height, there are two options for the ideal distribu tion of the warm air coming from Earny 2. 1. Racetrack The warmed fresh air flows in a circle and is distributed throughout the entire house, supported by multiple circulation fans with guide vane (FC050). The well-proven Vario air jet nozzle is used in this case. This is a very cost-efficient system with low service requirements. 2. Centretrack For houses with a ceiling height of more than four metres, Big Dutchman recommends blowing the warm fresh air along the...

Technology and efficiency: ✓ energy savings of up to 60 per cent depending on the location and application; ✓ heat recovery of up to 194 kW; ✓ supplied ready for connection for easy assembly; ✓ intelligent control with the ViperTouch climate computer or amacs; ✓ no unhygienic pipe system, no energy loss: extremely short distances between house and heat exchanger; ✓ fully-automatic cleaning of the filter unit during the batch (exception: Earny 2 S) to avoid performance losses; ✓ easy wet cleaning of the filters after the batch; in case of freezing temperatures, the filters can be removed easily...

Reducing emissions that come from livestock buildings and damage the environment is an important goal. Responsible authorities more often than not require measures that will ensure emission reduction. The focus is put on ammonia, odour and dust. Measurements carried out by the LUFA Nord-West (accredited German service laboratory) at a broiler farm with 41 100 birds per house (house 1 with heat exchanger (HE)), house 2 without HE) over a period of 44 days showed excellent results. Earny 2: Improved house climate and significantly lower emissions! 1. Ammonia - 29 % less ammonia emissions Ammonia...
