Diaper Poultry invests in new dispatch area cold room powered by Optyma™ Plus

Monday, February 6, 2017

For over 100 years, Diaper Poultry has built a strong reputation for the high-quality, fresh chickens it sells to butchers, farm shops, delis and restaurants from its headquarters near Stowmarket in Suffolk, England.

Recent years have been good at Diaper Poultry, and that has meant growth. With that growth came increased production and a need for quick expansion, especially in the factory's cold room.

The dilemma was how to complete the expansion with the safest, most energy-efficient solution, while ensuring as little impact as possible on daily production.

In cooperation with installation contractor Pitkin & Ruddock, Diaper Poultry looked at expanding the cold room and utilizing the factories existing refrigeration plant or to install new standalone equipment. The decision fell on building the new cold room powered by three Danfoss Optyma™ Plus condensing units.

"Diaper Poultry are really pleased with the result. Compared to the old refrigeration solution, the new Optyma™ solution is only about a quarter of the size, it works much more quietly and at the same time it is just as efficient as the old system", says Pitkin & Ruddock's Branch Manager Les Mitchell, who expressed confidence in Danfoss as the right choice for a safe and energy-efficient cold room solution.

The installation of these plug-and-play condensing units took just a few weeks, had no impact on existing production and proved to be a faster solution than retrofitting or expanding the existing cold room.

"We used the Optyma™ units in the past and know they are reliable products. They are very compact, easy to work on and maintain. Diaper Poultry appreciates that all refrigeration is in just one place that they can easily give a daily visual check up to make sure that everything is working", says Les Mitchell.

The installed Optyma™ units operate on R407F. Optyma™ Plus is a good choice for combining environmental gains with lower energy cost, even more with the availability for A1 including R448 and R449 for the INVERTER, and with the multi-refrigerant Optyma™ range, which is compatible with A1 and A2L refrigerants.
