Alter Wall 40: A prime example of high-performance refrigeration technology in Hamburg
Efficient cooling of buildings: At Alter Wall 40, ENGIE Refrigeration is demonstrating how high-performance and reliable refrigeration technology works in Hamburg – and thus ensuring the quality of stay in the attractive mix of buildings.
Solution:
QUANTUM chillers- Four QUANTUM water chillers of the type W0500-T2M00-0303 with the refrigerant R-515B together deliver a cooling capacity of 1,700 kilowatts.
- Thanks to its efficient operation, the refrigeration technology in Hamburg ensures the precise cooling of shops, offices, a data center, and a hotel.
A flagship for contemporary urban development: located in the heart of Hamburg's city center, the Alte Wall combines historic architecture with modern usage concepts. Number 40 in particular adds a fresh touch to the Hanseatic city with an appealing mix of office, retail, hotel and residential space covering around 40,000 square meters. Since modern buildings and a functioning cooling infrastructure are inseparable, ENGIE Refrigeration is providing the refrigeration technology for Hamburg's new flagship district. Four QUANTUM Water chillers are used to cool the individual buildings. Together, they deliver a cooling capacity of 1,700 kilowatts. In one building, QUANTUM ensures a pleasant, productivity-enhancing working environment in numerous offices. Various shops benefit from demand-oriented air conditioning, as does a bank's data center. In the lifestyle hotel The Hoxton, which is housed in another building, our refrigeration technology in Hamburg ensures comfortable temperatures in guest rooms and conference rooms. QUANTUM also dehumidifies the kitchen area.
Refrigeration technology in efficient use in Hamburg
The QUANTUM Water models in the Alte Wall 40 building impress not only with their powerful performance in cooling the building, but also with their efficiency. Based on the documented operating data and the defined comparison with the previous model, the chiller achieves annual electricity cost savings of €7,300 and an annual CO₂ reduction of 20 metric tons under the specified operating conditions. These project-specific figures describe the chiller’s energy performance in this installation and were considered when selecting the system for the building complex. As both the product portfolio and the services provided by ENGIE Refrigeration have already proven themselves in several properties in Hamburg's city center and HafenCity, the customer is also relying on our service team for the maintenance and repair of the refrigeration technology in Hamburg's district. This makes Alte Wall 40 a promising project that underscores the quality of ENGIE Refrigeration's products and services.
