VPM Cleanroom is built from individual compartments, which helps prevent contamination. Each compartment has an integral condensate tray from stainless steel and a drain for condensate water. The division of the unit into individual compartments makes access easy when carrying out maintenance and cleaning.
No screws or blind rivets have been used in the construction of the unit, which helps prevent leakages. The control system and frequency converters are placed on the front exterior of the unit in order to keep all surfaces inside the unit as even and smooth as possible. In addition, a closing mechanism has been developed especially to avoid breaking the evenness of the inner surface of the unit. The smoothness of the surfaces helps minimise the risk of contamination or leakages. It also makes it easier to clean the unit.
The position of the fans ensures that there is positive pressure in the clean side. That way, potential leakages inside the unit will move from clean to unclean air, and not the other way around. In other words, there is positive pressure in the supply air, and negative pressure in the extract air. The purpose is to avoid contamination and spreading of unwanted particles, and also to ensure that the laboratory is clean and the work environment safe.
VPM Cleanroom meets the requirements and standards of the authorities with regards to clearly separated air in ventilation of laboratories and clinically clean environments.
High level heat recovery
Traditionally, run-around heat exchangers have been used for heat recovery in ventilation of cleanrooms. Experience shows that run-around heat exchangers are 40-50 % efficient. In order for traditional units with run-around heat exchangers to meet the regulations by Ecodesign regarding heat recovery, run-around exchanger modules are now combined in series. Regulations require heat recovery of 63% in 2016 and 68% in 2018.
The new ground-breaking and patented VPM Cleanroom solution, which prevents the extract air from getting in contact with the supply air, brings the effect close to 100 %.
The patented technology used for VPM Cleanrooms means that the unit requires less space than conventional units. This reduces expenditure on expensive square feet compared to other similar units.
Solutions using conventional units require more space in order to meet current legislation for Ecodesign. European legislation prescribes heat recovery of 63% in 2016 and 68% in 2018.
Since conventional units typically have a heat recovery level of 40 - 50%, it is necessary to combine several modules in order to meet the regulations. A conventional solution therefore means a bigger unit, a larger machine room and higher building costs.
With Nilan’s VPM Cleanroom solution you will save on building costs for the machine room.
