Hospital LogiServe GmbH, Elmshorn

Markus Cramer is the person to thank for the fact that Hospital LogiServe GmbH can continue to operate at a site in Elmshorn, Germany: the furniture warehouse of the same name is the Hospital LogiServe's neighbour – Cramer is also the landlord. But the old building became too small and Markus Cramer was prepared to invest a high single-digit-million figure as a developer to build Hospital LogiServe a new site on the same street. Instead of 2,900 square metres, the healthcare logistics and material supply experts now have 4,700 square metres of warehousing and logistics space. 4,000 products, from dressing kits to surgical materials and heart catheters, are handled by 25 employees. However,the well-being of these employees, and conservation of the environment, was of paramount importance to those responsible for the building.

The use of wood as a renewable construction material, a green roof, a photovoltaic system and heat pumps are the central pillars of the environmentally-friendly project. The new building equates to Efficiency House 40 EE standard, meaning that renewable energy sources account for at least 65 percent of the energy required to supply the building with heating and cooling. It is not by chance that this is also the figure that will be required in future in accordance with the German Building Energy Act. Hospital LogiServe easily achieves this figure using a Kampmann low-temperature system.

But how do you heat industrial premises with a low-temperature system? Unlike conventional practice, systems with heat pumps have to be designed to supply multiple small, low-temperature-optimised units. In Elmshorn, Kampmann TOP C unit heaters are mounted on the ceiling of the building. They ensure consistently pleasant temperatures, which are generated draught-free and with only minimal temperature stratification.

The unit heaters are supplied by four KaClima AO heat pumps located on the retention roof. They are characterised by their minimal dimensions and thus the option of locating them in a very compact manner. They use the refrigerant R32, which is future-proof, even according to the F-gases Regulation and thanks to its low GWP (Global Warming Potential). Kampmann heat pumps are filled with only minimal quantities of R32, resulting in a reduction of the CO₂ equivalent by up to 75 %, without sacrificing the heat and cooling output.

The combined heat pump and unit heater system is extremely energy-efficient, keeping the operating costs low in the long term. There was also no need for Hospital LogiServe GmbH to connect to the gas supply network. Kampmann's SEL control panel also automatically controls the system, ensuring that employees always work in a pleasant and comfortable indoor environment.
