1. Customer and sector: poultry farming, food industry
The customer of MITA Cooling Technologies is one of the largest Polish poultry processing companies and exports throughout Europe and the world. It still operates its entire production process following the “from field to table” policy, relying on its own farms.
Each company in the food & beverage sector has its own refrigeration requirements, and this is no exception. Therefore, the company chose the services of some attentive parties, to listen to their specific and detailed requests: the EETS agency of Bartosz Jagieła, with the support of MITA Cooling Technologies’ staff.
2. Customer needs
The modernization of the poultry company’s facilities involved its central plant.
The plant uses autoclaves to sterilize the finished product and, during the process, the cooling liquid it uses (polypropylene glycol) had to be cooled from 60 °C to 20 °C.
The autoclaves had to be kept operational at maximum efficiency. One of the customer’s requests was to keep an eye on resource optimization.
3. The solution adopted: a PAD-V adiabatic cooler
The company’s needs fit the capabilities of our PAD-V 2-6 adiabatic cooler. This system is sometimes also called adiabatic dry cooler precisely because it uses a dual operating mode according to the period of the year to achieve efficiency and optimize resources:
- dry in cold periods;
- in adiabatic mode (therefore with water pre-cooling) during the hot season of the year.
The switch from one mode to another is manually programmable thanks to an easy-to-use PLC computer, and according to the actual needs of the period. The cooler selected works in dry mode below 18 °C outdoor temperature, wet up to 27 °C, and wet with a chiller up to 35 °C.
The system can be completely parameterized and automatically adjusts the rotation speed of its two fans depending on the thermal load, the outdoor temperatures, and the water and energy use objectives.
4. Critical success factors: reliability, efficiency, and savings
By admission of our customer, the offer submitted by MITA Cooling Technologies and EETS stood out for the clarity of its technical specification and for the reliability of the solution it proposed.
Actually, it is very simple to calculate the very low resource use of the cooling process provided by PAD-V:
- just over 10,000 kW per year for the motor-fan units,
- only 81 m3 of water per year for the adiabatic operation.
The temperature difference between the incoming and outgoing liquid is 40 °C throughout the year: efficiency and operational continuity.
