We see ourselves as a manufacturer and also as a problem solver. In addition to planning and design, our wide range of services also includes individual consultation; Krantz GmbH is at your side as a project partner. At Krantz, we ensure the success of your projects by means of an early cooperation and detailed planning. We support building owners, architects and plant engineers from concept development and design development through to energy assessment and profitability analyses. Through integration into the architectural planning, concept optimisation and variant analysis, we create planning security and optimum solutions for air distribution systems and cooling heating systems.

Research and development centre, Aachen

Our research and development centre in Aachen is equipped with the latest scientific and technical knowledge: a 12 m high experiment hall with 1,000 m² floor space; a Class 1 hall room with a volume of 200 m³ and a weight of 170 tonnes for acoustic measurements; a façade room for simulating outdoor climates from -15 °C to +40 °C; three room flow measurement rooms; a performance measuring room for heating and cooling systems and systems integrated in the façade; three air conditioning units with a total volume flow of 40,000 m³/h; and a refrigeration system with 250 kW cooling capacity.

Laboratory testing

• Room flow analyses to assess thermal comfort; trace gas analyses to determine the ventilation efficiency
• Demo laboratory room with fume hoods to analyse laboratory-specific air distribution systems
• Acoustic measurements (sound power level, transmission loss, sound absorption coefficient)
• True-to-life simulation of indoor air flow in industrial and comfort areas at a scale of 1:1
• Performance tests on cooling and heating elements, induction units and façade units, to confirm technical design data and support planners and architects
• Flow and acoustic analyses on newly developed components

Computer-aided simulations (CFD) and calculations

We use computer-aided simulations (CFD) to develop products as well as for the examination of room air flows. We also support our customers with complex calculations of pressure losses in branched duct networks and carry out acoustic calculations. We offer you the opportunity to gain your own impression of your construction project in our R&D centre. If required, we can also carry out on-site investigations.

Planning and design

The correct design of Krantz products for the respective requirements is decisive for an optimum function. In comfort areas, such as offices, restaurants or hotel rooms, comfort is the main focus. In industrial areas, such as production or painting halls, the dissipation of heat loads or pollutants is a top priority.

Customised solutions

We are experts for special solutions, from product customisation to the development of new products. Our innovative and technically qualified team of engineers falls back on many years of experience and works closely with our research and development team. For the Elbphilharmonie concert hall in Hamburg our engineers developed a special air outlet for installation under the 2,150 seats, approved following intensive laboratory tests and a comparative study with a competitor's product at the Wolfenbüttel University of Applied Sciences.
