As we started the process of developing our own units in the 1990’s, our goal was to provide the market with the best solution possible. This ethos has not changed as we invest heavily in R&D and provide new and improved products to match the demand in this developing area.
The current models, the ProAir 300 & 600 units were among the early listings on SAP (Standard Assessment Procedures) Appendix Q, when it was instigated back in 2006. This is the route through which product performance data is made available to SAP assessors.
In order to achieve a listing on Appendix Q, the product is tested by the Building Research Establishment (BRE) in the UK. This test is primarily an assessment of the energy efficiency of the unit, but is also rigorous in its treatment of other aspects of M.V.H.R
It is also the means by which test and calculation methodologies can be agreed that can be used to measure product performance and when and how that performance can be treated in SAP. Both the heat exchanger efficiency and the motor efficiency (specific fan power –SFP) have been verified by tests carried out by the Building Research Establishment (BRE) in the UK. The results are posted in their online database which acts as Appendix Q of the SAP and DEAP systems. These tests have been done in accordance with the EN 13141-07 Standard which is rigorous in its treatment of other aspects of HRV as well as energy efficiency.
The ProAir 600 qualifies for best practice standard of the Energy Saving Trust. The ‘Best practice’ fan power for MVHR as defined by the EST is for less than 1W/l/s. This recognises that it is one of the most energy efficient products available in the UK market. This means reduced costs and lower carbon emissions helping to provide more cost effective solutions for Code for Sustainable Homes certification. The ProAir units incorporate the latest in fan technology. The new electronically commutated EC direct current motors provide advantages such as high efficiency, low noise and sensitive control.
