Rules for NRVU units
NRVU units are units with a nominal airflow above 1000 m³/h.
Directives
The requirements of the Ecodesign Directive primarily concern:
Although the definition of the limit values for power consumption is somewhat complex, the minimum requirements for heat recovery are clearly defined and determined as follows:
From 2018: Plate heat exchangers at least 73%, but liquid-coupled batteries only 68%
As mentioned, the directive also sets requirements for the specific electricity consumption (SFP). This is described in a formula that depends on a number of factors – including the actual temperature efficiency.
VEX overview
To make it clear and easily accessible, EXHAUSTO has prepared a table with calculations based on a nominal operating point and reproduced the result as table values. This table contains data for the compact VEX programme. Find a link to the VEX overview at the bottom of the page.
Calculation programs
In our calculation programs, you can find out whether a specific unit meets the Ecodesign requirements at a specific operating point. All EXHAUSTO NRVU units comply with 2018 requirements.
The Ecodesign guidelines do not apply here
As a starting point for whether a ventilation system must comply with the Ecodesign Directive, one can say that:
The Ecodesign guidelines do not normally apply to “clean” process ventilation, in corrosive environments, at air temperatures above 100°C and when transporting flammable gases and vapours.
Example of places where the Ecodesign requirements do not normally apply:
Industrial hood where the ventilation system does not also include room ventilation (for people)
Data centres, server rooms
Recirculation system (<10% outdoor air share)

Local Requirements
The individual EU countries’ requirements for temperature efficiency have been deleted and replaced by the requirements in the Ecodesign Directive, whereas the requirement for SEL/(SFP) still applies in many EU countries, as this requirement applies to the fully installed ventilation system, including pressure loss in ducts, fittings and roof hoods, etc., i.e. the finished installation.
