CTP and Raben install Europe’s largest heat pump in Warsaw
Europe’s largest heat pump has been installed at CTPark Warsaw West by CTP and Raben Group. The installation of 87 Mitsubishi Electric units with a total capacity of 12.4 MW will heat and cool two warehouses with a total area of 110,000 sq m on a daily basis, and is also the second-largest in the world behind a heat pump installation in Japan.
Warsaw West is one of CTP’s zero-emission industrial and logistics parks, with no fossil fuels used to heat the buildings and rooftop photovoltaic installations powering the Mitsubishi Electric heat pumps, in addition to the park’s existing sustainable features.
“What sets this installation apart on the warehouse and logistics market is its scale and innovation,” said Piotr Gęśla, deputy division manager Mitsubishi Electric. “The CTPark Warsaw West complex, thanks to its zero-emission approach and integration with photovoltaic systems, has created ideal conditions for the implementation of the project, which not only meets the highest ecological standards, but also achieves significant operational efficiency.”
In 2023, Raben Group signed an agreement with CTP to lease 110,000 sq m at CTPark Warsaw West in Wiskitki, comprising two of the five buildings being built, in what was Poland’s largest logistics deal of the year. Raben Group is due to move into these buildings later this year, which will be used to carry out warehousing and forwarding operations supplemented with a whole range of added services, including packing or contract logistics.
“The contract with Raben Group for the space at Warsaw West was signed for a period of 10 years, allowing the tenant to invest in such an extensive heat pump installation, which will allow it to optimise its ongoing operating costs, as well as implement its ESG strategy,” said Piotr Flugel, managing director, CTP.
At Raben Group’s space at the park a number of modern solutions are being implemented to meet its decarbonisation strategy. This includes climate control of warehouse space (humidity and temperature control and heating of warehouses) through heat pumps.
The use of heat pumps combined with highly efficient underfloor heating technology ensures efficient use of electricity, minimising carbon dioxide emissions into the environment. The estimated effect of these technologies used will be a reduction in carbon dioxide emissions by 700 – 750 MgCO2e/year compared to an equivalent warehouse space heated with gas.
The Mitsubishi Electric units installed in the facilities have been grouped into eight cascades for underfloor heating in each building, the installation of which includes 150 kms of pipes, a record for the Polish market. The four cascades also produce chilled water, which is used to cool down the storage space using heating and cooling apparatus.
Each of the heat pumps installed at CTPark Warsaw West has four cooling circuits and uses so-called inverter compressors, which allow adjusting the heating and cooling power to the tenant’s needs and make the entire system reliable regardless of weather conditions. The units used were designed in such a way that heating can occur even when the external temperature reaches -20oC.
