Size a unit in minutes

The MCX selection software works the way a specification does. Enter your airflow, external pressure, application and location, then build the unit section by section — heat recovery, coils, filtration, controls and options.
Performance, energy class and an indicative price update as you configure, so you can test alternatives before committing to one.

/ SOFTWARE SELECTION

Specify your unit before
you
pick up the phone

Hydronic's selection software takes you from an airflow figure to a fully configured unit — with dimensions, performance data, drawings and BIM files you can drop straight into your project.

Configure, don't compromise

Standard equipment forces you to round up or accept less.
The MCX is built from 21 single flow and 24 double flow sections, so the unit you specify is sized to the project rather than to a catalogue.

See the consequences as you go

Every change updates the numbers. Airflow, pressure drop, Eurovent energy class, SFP and sound levels move together, so a decision on the heat exchanger is never made blind.

Technical engineering drawings and blueprints

Leave with the files

Dimensional drawings, a BIM object and a technical datasheet are generated from your configuration — the same files you would otherwise wait for.

/ OUTPUTS

Everything you need to specify

BIM object

The unit dimensioned and positioned for your model

2D drawings

General arrangement drawings, ready for the project file

Indicative price

For the configuration exactly as selected

Energy values

Eurovent energy class and SFP on your operating conditions

Performance data

Airflow, pressure, sound levels and heat recovery efficiency

Dimensional data

Overall dimensions, module breakdown and service clearances

Outputs are generated for the configuration you build — not for a nearest standard model.

/ MCX DESIGN

When the project needs
more than a standard
selection

For projects with constraints the standard configuration cannot absorb, our engineers work with you in MCX Design. Motors, fans, humidifiers, hot and cold water coils, acoustic baffles and communication gateways are selected component by component against the specific requirements of your project.
Customer drawings can be produced, and BIM schematics are available from the first consultation.

Component-level selection

Every element chosen against your specification rather than a preset.

Custom drawings

Project-specific drawings produced on request.

BIM from first consultation

Schematics available before the specification is fixed, not after.
