To calculate capacity data use the product selection tools Quickselect and EXselect.

Total energy consumption is divided equally between the extraction and supply air fans.

Power consumption with VEX: P1(W) = SFP (J/m3) x qv (m3/s)

Efficiency with condensation:
Extract air = 20°C/55 RH
Outdoor air  = -10°C/50 RH
Balance between supply air/extract air = 1,0
kort-lang-stiplet-streg
Efficiency without condensation with imbalance:
Extract air = 25°C/28 RH
Outdoor air = 5°C/50 RH
Balance between supply air/extract air  = 0,8

Balance between supply air/extract air = 1,0

Calculation

The temperature efficiency of the VEX units is shown at different airflow ratios, calculated as:



t2,1 = Temperature of outdoor air (fresh air)
t2,2 = Temperature of supply air
t1,1 = Temperature of extract air

Condensation outlet

The condensation outlet (DN32) can be lead out in all four directions. EXHAUSTO offers a complete water trap and heating cables for the outlet as accessories.
(The condensation pipe is not supplied by EXHAUSTO).

SPLIT unit

VEX360H

If the VEX360 needs to be transported through passages that would otherwise be too small for it, if it can be ordered as a SPLIT model.

As a SPLIT model, the unit is delivered assembled but not sealed, so that it can be split into smaller sections on the site and transported in smaller sections to the location where it is to be installed.

This work must be carried out by a certified EXHAUSTO service technician.
