*Price indication

Since 1877, the way Kiefer thinks and acts has revolved around optimum solutions and products. The aim has always been to create ventilation and air-conditioning technology that is fit for people, does not harm the environment and saves energy – and today more than ever. Our customers' satisfaction is very important to us. This means that we are on hand during every phase of the project: from the initial sketch through the finished project all the way to installation and maintenance services.

INDUL linear diffuser
Slimline linear diffuser for maximum thermal comfort and unobtrusive installation in all types of ceilings, even where space is at a premium. The reliable free jet characteristics prevent dirt deposits along the air diffuser, keeping ceilings clean for longer.

Energy
The extremely high induction rate of INDUL linear diffusers enables draught-free operation even at very low supply air temperatures. This creates significant potential for saving energy through the use of free cooling.

Design
The slender diffuser profiles blend perfectly into any ceiling architecture and keep ceilings dust-free for longer. Whether unobtrusive or deliberately accentuated, they will meet all architectural requirements.

Technology
INDUL free jet characteristics are unique in enabling a continuously diffuse ambient air flow and allow temperature differentials of down to -14 K, without the slightest compromise on thermal comfort.

Function
The supply air is divided into fine alternating free jets, which intensifies the induction of ambient air. This high level of induction permits a substantial temperature differential between the ambient air and supply air, and in particular the use of free cooling. The required cooling capacity is reduced to a minimum. Effective insulation of the plenum box largely prevents energy losses despite the low temperatures. And thanks to the use of recycled aluminum, the INDUL air diffuser scores highly on lifecycle costs, as evaluated by current certification systems.

The classical ambient air flow
The specially developed discharge geometry produces fine individual air jets. Ambient air can be effectively induced at the edges of the individual jets. Through the induction (admixture) of ambient air, the temperature differential between the supply air and ambient air is balanced out over a short distance. The discharge velocity of the supply air is also reduced by the time it reaches the occupied zone, with the result that no draughts are perceived.

Installation

The Kiefer INDUL vent can be installed hanging on installation rods (not included in delivery). The 125mm spigot is compatible with the Blauberg BlauFast system:

Connect 2x 90mm BlauFast ducts (RK90) with valve adaptor RPZ125/90x2 to spigot of 1m Kiefer INDUL diffuser. Respective only one duct is needed for 0.5m INDUL diffuser.

SolutionAir offer innovative products and advanced solutions, to protect our living environment and enhance our personal well-being. Adequate ventilation within a building ensures good air quality, by removing toxins and CO2. It also helps to control humidity, thus reducing the risk of condensation.

Our living conditions are changing. What once was the norm, today is becoming unobtainable. Changes to the Unitary Plan in Auckland, increases in industrial investment, increases in noise pollution are contributing to changing our lives as they once were.

Residential buildings are also changing to keep pace with an ever-changing environment, new building requirements, new materials and the introduction of new technologies.

New Zealanders are slowly coming to the realisation that in winter our houses are actually cold, humid and damp, and that mould spores are the cause of many respiratory illnesses such as asthma.

The World Health Organisation and the Global Initiative for Asthma predicts that by 2025, some 400 million to 450 million people will have asthma. A New Zealand-led assessment, which combines previous studies, estimates that about 5 per cent of the global population, suffers of asthma. The rate among New Zealanders is 15 per cent. Should these numbers call for warmer homes, better insulated homes, healthier homes as a whole? We believe so!

Energy efficiency and thermal comfort can also be enhanced. Air quality can be affected by a number of impurities, such as low-level irritants (dust, pollen) right through to radon and volatile organic compounds. In humid or colder areas, and particularly in uninsulated buildings, there is also a significant potential for condensation when humidity levels are too high, and this can result in mould growth and various health issues like asthma.

The market is currently saturated with wrong or misleading information. One such misleading example is that you can vent your house by opening windows and doors for a few minutes. This process is known as natural ventilation.

International studies have shown that to ensure adequate ventilation by natural means, the windows in a reasonably well-sealed home would have to be opened at least four to six times a day for a reasonable amount of time (around 10 to 20 minutes, depending on the size of the home, openable window area, prevailing ambient conditions, etc). Now refer this to a cold winter’s day when you have just spent the entire morning trying to heat it up. Opening windows and doors to introduce much needed fresh air is going to push all the heat you have generated and paid for out of the window and simultaneously it will introduce cold air. Not the ideal result we should be looking for.

Take positive pressure ventilation as an alternative solution. This is the process of pushing roof air into your house. Air that has to find a way out of the building envelope in order to take stale/moist air and pollutants out of your home. Unless the home offers dedicated escape routes for this air to exit the building envelope, air will start to exit your home through power points, downlights and other unconventional openings in the house. Once stale/moist air starts exiting your home through power points, it will start to rot your house from the inside out. As there is no escaping the building paper and gib cavity the timber will start to absorb this moisture to the point of saturation and then it will start to rot. Once again, not the ideal result we should be looking for.

None of the above is not a new phenomenon, in fact many countries around the world have been working on how to deliver fresh air ventilation while keeping heat inside your home. Maybe because some countries have much harsher winter conditions, they have had to find a solution faster than we in New Zealand. The advantage we now have is that such solutions have been developed by internationally acclaimed companies such as Blauberg and Maico from Germany or Utek, Elicent and Aertesi from Italy.

Solutionair is privileged to have been representing these companies in New Zealand and to be in a position to benefit from years of experience to help New Zealanders find a solution for their home ventilation.
