Based on your request, we offer the following tests of air-handling units.
Test a) Air curves for all of the filter types and for HRV and ERV units for air flows 150 and 200 m3/h. 
In this test dependency of internal pressure drop, external available pressure and electric power on the air flow rate will be measured for each of 16 combinations of both units, heat recovery types and all filter types. Also stand-by power will be measured.
The methodology will follow EN 13141-7:2010
47 000 CZK (excl. VAT)

Test b) Thermal efficiency of heat recovery (HRV) and enthalpy recovery (ERV) according to EN 13141-7:2010 and EN 308.
For both versions of heat recovery systems applied in both air-handling units will be measured temperature and humidity ratios for balanced mass air flows at 3 points. Mandatory test (EN 13141-7, table 6, point 1, outside air inlet temperature is 7 °C) for category I will be performed. 
Additional test with different temperature conditions upon request.
54 000 CZK (excl. VAT)

Test c) Acoustic tests – NOT our expertize.

Test d) Air leakage tests according to EN 13141-7.
Internal and external leakage will be measured for air-handling units with both types of heat recovery exchangers.
Tracer gas test upon request.
40 000 CZK (excl. VAT)

Test e) IP Protection - NOT our expertize.

Test f) Drainage testing in a climate chamber
Test of condensate drainage under non-freezing conditions for air-handling unit with heat recovery (HRV).
28 000 CZK (excl. VAT)
Other tests (not requested):
Test of antifreeze protection which include safety shutdown, antifreeze switching threshold, antifreeze protection efficiency and critical temperature (around 24 000 CZK (excl. VAT) for 1 air-handling unit)
