Decentralised recirculating air cooling system that sets new standards in terms of dimensions, cooling capacity, acoustics and thermal comfort. The INDULVENT connect offers 3D ambient air conditioning: maximum cooling capacity, low level acoustics and highly effective induction characteristics result in above-average user satisfaction. It functions as a 2-pipe system for cooling and a 4-pipe system for combined heating and cooling mode. Additionally, the unit can optionally be operated with a supply air socket, allowing for flexible adaptation to specific ventilation requirements.

INDUCOOL is a high-capacity chilled ceiling panel. Cooling is carried out using air and water simultaneously. The supply air is distributed draught-free into the occupied floor by the integrated linear diffuser. This process considerably increases the heat transfer and cooling capacity.

Owing to its induction effect, the integrated linear diffuser draws the warm ambient air over the water-cooled aluminium fin plates. Depending on the dimensioning, this achieves a cooling capacity of up to 500 W/m. It is therefore sufficient to cover just 5-10% of the ceiling area with INDUCOOL panels. The rest of the ceiling is freely accessible and is available for any kind of architectural design. The induction at the underside of the INDUCOOL panel – and therefore directly within the room – ensures a rapid reduction in the velocity of air leaving and the temperature differences so that the highest requirements in terms of ambient comfort are met in the occupied zone.

The compact and acoustically highly effective transfer grille element for partition wall installation.

INDUSILENT enables free transfer of air from room to room. The acoustic weakening of the partition wall as a result of the transfer grille installation is minimised owing to the highly effective integrated inner lining. Taking account of a maximum pressure difference of 20 Pa, specific air flow rates of up to 200 m³/hm are possible.

Installation length: 500, 800, 1000, 1200 mm special lengths on request
Box length: 230 mm or 340 mm (Type T) / 300 mm (Type S)
Air flow rates: bis 140 m³/hm
Pressure loss: < 20 Pa
Wall thickness: from 58 mm (Type TS)
Building material class according to DIN 4102: A2 (incombustible)

An all-rounder for light – ventilation – cooling – acoustics

The INDUSAIL LUMINOUS is a multifunctional lighting sail system. Pleasant acoustics are combined with comfortable cooling and ventilation, as well as integral LED area lighting. This provides near-daylight quality, glare-free illumination based on circadian light cycles, thereby reducing fatigue.
Four functions for the perfect indoor environment:

• Draught-free supply of fresh air
• Comfortable cooling
• High sound absorption
• Intelligent ambient lighting
  
  

The right solution for every space

The perfect indoor environment thanks to four functions: superb lighting, draught-free fresh air supply, comfortable cooling and a high level of sound absorption for a feel-good climate to everyone's liking. The INDUSAIL LUMINOUS offers flexible expansion options and can be combined with the plus, air and silent designs. It can be used in isolation in individual offices, for example, or throughout open-plan offices. As such, the INDUSAIL LUMINOUS offers maximum flexibility when it comes to designing the office landscape.

CONCRETCOOL – a symbiosis between component temperature control and supply air provides comfort with high energy efficiency owing to maximum utilisation of free cooling. Almost completely invisible introduction of supply air. Above-average customer satisfaction.

Cooling tubes, made of aluminium with high thermal conductivity and with diameters of 60 or 80 mm, are cast into concrete ceilings in a grid. The internal surface is ribbed to improve heat transfer. The supply air is not fed directly to the rooms: it firstly flows through the cooling tubes within the concrete ceilings. This warms the cold supply air to approximately ceiling temperature, the required  heat being taken from the ceiling. This withdrawal of heat provides the cooling for the ceiling. This supply air is then fed to the room through Kiefer air diffusers, meeting the hygiene requirement for fresh air. An outlet temperature of approximately 21°C is achieved for the supply air without using a supplementary heater. The process is self-regulating and virtually free of variation. The temperature is extremely stable owing to the high storage capacity of the concrete ceilings. Heat recovery by the ventilation system is increased to over 95 % by the addition of the CONCRETCOOL system. As a result, the requirements set out in the German Renewable Energies Act are exceeded. Combined with the potential of free cooling, this results in unparalleled operating costs and high energy savings.
