As pioneers of the world's first air outlets and committed to high technological standards, we fulfil the highest requirements for air distribution systems and air/water systems. Krantz air distribution systems offer unique design options, as an architecturally integrated solution or invisible in the room. Our systems are diverse in terms of execution, design and function. We ensure that the selection, placement and design of the air outlet maximise comfort and ventilation efficiency. Whether office, classroom or concert hall: Krantz offers a comprehensive portfolio and best practices with regards to sustainability.

Comfort outlets for ceilings, walls and floors

• Opticlean OC-Q and OC-R: supply air outlet with horizontal discharge for suspended ceiling systems with 600 × 600 and 625 × 625 mm grids or 12.5 mm gypsum board ceilings, 40 to 860 m³/h, very uniform discharge with extremely low ceiling soiling; thermostatic control unit OC-V
• Adjustable induction outlet IN-V: for installation flush with ceiling where manual adjustment of discharge direction is required, 10 to 400 m³/(h·m), also as return air inlet
• Radial outlets RA-V and RA-N; twist outlets DD-VL, DD-VG and DD-N; radial slot outlets RL-Q2, RL-R2 and RL-C; linear whirl outlet WL; jet and swivel nozzles DW; air transfer elements OG
• Wall slot diffuser WSD: supply or return air in slim design with high induction effect for turbulent mixing ventilation, up to 240 m³/h per metre, for 100 mm plasterboard walls, cleanable per VDI 6022
• Broad multiplex outlet BF-V: sidewall air outlet fulfilling the high thermal comfort criteria for commercial applications to EN ISO 7730, e.g. hotel rooms, 80 to 540 m³/h, suited to fan coils
• Floor outlets: rotary floor twist outlet DB-D for raised floors, 20 to 180 m³/h, can be walked over, driven over and can support a wheel chair; floor twist outlet DB-E; floor displacement outlet Q-B; adjustable floor outlet BA-V; installation manual for floor outlets
• Seat and step outlets for auditoria: seat displacement outlet Q-ST, step displacement outlets Q-SL and Q-SR, linear step twist outlet SD-L, as used at the Elbphilharmonie Hamburg (2,150 seats, 60 m³/h per person), the Stephen A. Schwarzman Centre at Oxford University and the Guildhall School of Music & Drama in London

Displacement outlets for comfort and industry

Industrial air distribution systems help to control the pollutants generated by production processes by displacing contaminated and polluted air. This reduces the health risks to employees and ensures better indoor room air quality, contributes to lower energy costs and increased productivity.

• Circular displacement outlet VA-ZD: low-turbulence supply air flow, up to 10,000 m³/h, DN 250 to DN 630, penetration depth up to 20 m, stepless adjustment from horizontal to vertical downflow by hand, servomotor or thermal control unit
• Radial displacement outlet VA-PV: for factories where the supply air must be discharged downwards from a height of 4 to 10 m at low turbulence, 1,000 to 8,000 m³/h, DN 315 to DN 710
• Circular hybrid displacement outlet VA-ZH and linear hybrid displacement outlet VA-LH: for factory halls of printing plants, metal processing, injection moulding or the automotive industry, especially for systems without mechanical cooling or with adiabatic cooling
• Rectangular, trapezoidal, conical, laminar and swivel displacement outlets VA-RV, VA-T, VA-TH, VA-K, VA-L, VA-S; ceiling displacement outlets Q-DV and Q-DN
• Kuwait International Airport: more than 6,200 outlets designed, manufactured and supplied, including over 5,500 rectangular displacement outlets, with 7 CFD simulations

Indoor firing ranges VA-RSA

Shooting with firearms in indoor firing ranges releases gases and airborne particles which pollute the indoor air. The VA-RSA generates a low-turbulence piston flow with an air velocity of 0.25 up to 0.35 m/s over the entire room cross-section, supplied horizontally over the full rear wall behind the shooters, stable at ΔT up to ± 4 K, with no influence on ballistics. Modular system with prefabricated components, door and window integration, proof of function at commissioning, in accordance with the Shooting Range Directive of the German Federal Ministry of the Interior. 20 years in service.

Customised outlets

Krantz is your partner for complex refurbishment or new construction projects with outstanding acoustic and architectural requirements. For Charter House Street UK, Krantz UK commissioned the measurement of thermal comfort, visualisation of the room air flow and determination of the sound levels; the challenge was to develop a new diffuser that combines two different outlets. The customer ordered more than 500 hybrid outlets.
