Vindur Top Air Conditioner System for destruction of viruses
Waves of infection such as the current outbreak of the coronavirus are a worry for many people. At the same time, they sharpen awareness of hygienic room climate issues, and increase interest in ventilation and air-conditioning systems in public buildings and holidays. With Vindur Top®, Weiss Technik has developed an innovative hygienic air-cooling unit which prevents the growth of viruses, bacteria and mould thanks to a four-stage safety concept which includes specially sized HEPA filter, UV lamps, silver ion coating and thermal disinfection.
The four stage concept helps to filter viruses, germs and bacteria, fungus and mould out of the air and eliminate them reliably.
What is the Vindur Top hygienic air-cooling units
The Vindur Top are hygienic air-cooling units often used as supplementary or retrofit solutions if the primary building climate equipment is not dimensioned sufficiently for all rooms or if additional cooling is required. The Vindur Top is an established product and the new Coronovirus version has simply been fitted with the H14 HEPA filters and a UV Type C lamp which kills the virus. Other than these small modifications it remains the same highly reliable unit that has been deployed around the world.
Four-stage safety concept explained
The Vindur Top uses highly effective H14 HEPA filters which reliably filter 99.9997% of micro-organisms, bacteria and viruses from the air. UV lamps safely kill viruses, germs and bacteria that have been accumulated by the filter from suspended particles. The inner plates of the cooler are coated with silver ions, which prevents viruses, bacteria, germs and mould from spreading. After the unit is switched off, heat exchangers and condensate tray are heated automatically to approx. 70 °C for 10 minutes. This dries out the biofilm which can form due to cooling, and reliably kills micro-organisms and viruses with heat.
Thermal disinfection kills micro-organisms
To improve hygiene further, Vindur® Top units can be equipped with optional thermal disinfection. This newly developed method effectively prevents the growth of micro-organisms such as bacteria and mould in the air-conditioning unit. Here, the heat exchanger and condensate drip tray are heated and dried completely in turn, controlled by a humidity sensor, so that all micro-organisms are safely destroyed.
Simple handling, two model variants
Vindur® Top hygienic air-cooling units can either be mounted under the ceiling or, equipped with intake and pressure side channel connections, integrated in a suspended ceiling. They have an energy-efficient EC ventilator and a cooler with condensate lifting pump. Air quantity and temperature can be controlled easily and comfortably via the DDC control with web visualisation using the room control panel or touch display. In addition, their smooth surfaces make them easy to clean and disinfect. All the relevant unit parts can be accessed easily through the downward-opening housing flap. This guarantees the straightforward replacement of spare parts.
Meets the very latest German hygiene requirements
The German industry standards body (DIN) and the Association of German Engineers (VDI) recently re-defined the hygiene requirement for ventilation and air conditioning equipment for rooms occupied by persons in DIN 1946-4 and VDI 6022 respectively. In DIN 1946-4, the term rooms occupied by persons, room class II, is used for patients’ rooms, examination and recovery rooms as well as control rooms for CT and MRT scans. However, workstations in office and industrial buildings, sports facilities and break rooms as well as sales and event rooms are also subject to the requirements of VDI 6022. With Vindur® Top, the air conditioning specialist Weiss Technik MediClean® is the first company in the world to offer a hygienic air-cooling unit that reliably meets the new requirements.
