Large building Testing

Retrotec’s multiple fan panels can be added in modules to test any building of any size. It is very rare to require more power than the standard double blower system but if needed, Retrotec can rent as many blowers as needed for any job.

In the UK, air leakage tests must be carried out in accordance with CIBSE TM23 on all buildings over 1000 sq.m. The Retrotec Model M55 shown will test enclosures up to 2880 sq.m. of envelope area at the minimum allowable leakage of 10 cu.m/hr./sq.m. It can be expected that much larger buildings can be tested with the same system if they perform better than this minimum.
