Earny 2 heat exchanger

Saves heating costs, improves the house climate and reduces emissions

With Earny 2, Big Dutchman can offer you a heat exchanger with optimised technical features. Its predecessor has been proving its worth on the market successfully since 2011. The heat exchanger recovers the thermal energy in the exhaust air of poultry houses. This means:

  • heating cost savings of up to 60 percent;
  • an improved house climate;
  • reduced emissions.

Earny 2 is available in three sizes, based on the number of birds in the house.

Technology and efficiency:

  • energy savings of up to 60 percent depending on the location and application;
  • heat recovery of up to 194 kW;
  • supplied ready for installation for low assembly requirements;
  • 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 to avoid performance losses;
  • easy wet cleaning of the filters after the batch; in case of freezing temperatures, the filters can be removed easily and quickly for cleaning inside the house;
  • the height of the exhaust air pipe from the house into the heat exchanger can be selected flexibly on site; as an alternative, an opening can be made to connect the filter chambers directly with the house;

Animal and environment protection:

  • improved house climate for healthier birds and better production results;
  • dry litter for healthy feet;
  • reduced use of medication;
  • lower CO2 emissions thanks to heat energy savings*;
  • reduced emissions from the house (ammonia, dust, odour);
  • adjustment of the humidity;
  • can be retrofitted in old and renovated houses;
  • optionally available in the colour green.

* 37 t less CO2 per year for a house with 42000 birds and utilisation of natural gas

Earny heat exchanger tested by the DLG

The heat recovery efficiency of the Earny heat exchanger for poultry houses is far above standard. Comprehensive tests under practical conditions in the context of the renowned DLG FokusTest have proven this. For the excellent test results see the test report available for download.

Open house with a live look at poultry growing

It was a huge success: Recently, the Schedl family invited 4,000 visitors to an open house on their farm in Bärnau, Germany. The farm fest started with the inauguration of two new buildings for poultry growing. A total of 80,000 animals are housed in the buildings. The facilities contain Big Dutchman poultry housing systems, which guests learned about in detail during an informative tour. The…

Reducing heating costs and emissions in poultry houses

With Big Dutchman's heat exchanger Earny, poultry managers can save up to 60 percent of heating costs for their poultry house during the winter. However, there is even more to Earny: The heat exchanger also reduces dust, ammonia and odour emissions as determined by the measurements of the accredited laboratory LUFA Nordwest in Oldenburg, Germany. Emissions play an important role in many regions…
