Krantz cooling and heating systems offer a high level of thermal comfort, optimised energy efficiency and many architectural design options for design-conscious new and old buildings. In addition to cooling and heating, functions such as air distribution and sound absorption can be added. Water-based cooling and heating systems are an indispensable component in the optimised air conditioning of an occupied area.

Multifunction ceiling sails AVACS and KrantzCool

AVACS stands for Air Ventilation And Cooling System. The AVACS multifunction sail combines the following functions: cooling, heating, indoor air circulation and sound absorption, which are performed in compliance with thermal comfort criteria.

• Standard cooling capacity to EN 14240 165 W/m²; standard heating capacity 190 W/m²; length 1,000 to 6,000 mm; width 800 to 1,350 mm; height 50 mm
• Very high output in relation to the active sail area thanks to built-in induction unit, not visible from below; heat transfer by convection and radiation; good acoustic properties; no combustible components
• Variants: AVACS Acoustic, Cooling & Heating, Supply Air, Recirculating Air, Ventus and Ventus Plus; multifunction exposed ceiling for open ceiling architecture; integration of lighting, air outlets, speakers and smoke detectors
• KrantzCool: developed for suspension close to the concrete ceiling, extremely compact, two-sided supply air discharge using the Coanda effect, uniform appearance with perforations throughout
• Stream Berlin: 3,100 cooling panels and 2,000 induction units across 50,000 m² of floor space, with sound absorption measured in our R&D laboratory

Static cooling ceiling systems SKS

High-capacity elements for installation above open, suspended ceilings; suitable for cooling all room types and applications but also usable for heating. SKS 4/3: standard cooling capacity 175 W/m² to DIN EN 14240, operating pressure up to 16 bar. SKS 4/3-duo for concealed installation: 216 W/m² without suspended ceiling, suited to offices with high heat loads, television studios, technical rooms and industry. Copper serpentine pipework in one piece to DIN 1787 with aluminium fins; uses the concrete ceiling retention capacity; low installation height for renovation. Also SKS 5/3, SKS Slimline, SKS Alcedo and contact cooling ceilings KKS.

Chilled beams DK-LIG and DK-F

For room cooling and heating in commercial and industrial buildings, with fresh air supply to enhance the indoor air quality. Compact unit for fresh air supply as well as for cooling and heating according to DIN EN 15116. DK-LIG/Z two-sided discharge: model 300 cooling up to 620 W/m, model 600 cooling up to 826 W/m; DK-LIG/E one-sided discharge for placement along façades and walls; heat exchanger cleanable from the room; lengths 1,200 to 3,000 mm.

Induction and ventilation units for façades

Induction unit for cooling, heating, and fresh air supply along the façade, through window parapets, with low-turbulence supply air discharge according to the principle of displacement ventilation (IG-Q-SB) or mixing ventilation (IG-M-LB, IG-M-SB). Low pressure loss (70 to 200 Pa); heating also possible without primary air; heat exchanger cleanable in compliance with VDI 6022. Ventilation units LG for mixing and recirculated air. Bayer AG Krefeld: IG-M-SB induction units in vertical parapets supply tempered fresh air to the offices.
