VEX350H

Technical data, VEX350H

 Conditions:

- Density = 1.2 kg/m³
- Pressure ratio < 1,11
- other points in acc. with EC327/2011 (see product instructions)

Temperature efficiency, VEX350H

The temperature efficiency and, to a lesser extent, the SFP/SEL values for a specific air handling unit are closely connected to the heat exchanger itself and depend upon the manufacturer. As suppliers can change from time to time, small changes in the technical data can occur, which is why it is always recommended that you perform a calculation for the particular project using our calculation software, EXselectPRO

The curve is intended as a guideline, and it is recommended that a calculation be performed using the calculation software EXselectPRO for the individual project.

	Efficiency with condensation: Extract air = 20°C/55 RH Outdoor air  = -10°C/50 RH Balance between supply air/extract air = 1,0
	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
	Efficiency without condensation in acc. with EN308: Extract air = 25°C/28 RH Outdoor air = 5°C/50 RH Balance between supply air/extract air = 1,0

Calculation

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

Dimensional drawings, VEX350H

VEX350H - Left

All dimensions in mm.

1) Allow a distance for service in front of the unit that is equivalent to the unit depth
2) Allow min. 200 mm free height for service

The doors can be removed for internal transport, allowing the heat exchanger sections to be moved through a 900 x 2,000 mm opening.

VEX350H - Right

All dimensions in mm.

1) Allow a distance for service in front of the unit that is equivalent to the unit depth
2) Allow min. 200 mm free height for service 

The doors can be removed for internal transport, allowing the heat exchanger sections to be moved through a 900 x 2,000 mm opening.

Outdoor model with cover

With outdoor installation, the unit must be secured to the building at the points shown in the instructions. 

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, VEX350H

If the VEX350 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.
