What can you do with Gerhman Suite?
Start with a product, work through its performance, and keep your selections together under your project.
Find
Explore Gerhman products and review the options for your application. The product configurator is being developed within this area.
Calculate
Define the room and operating conditions, set the technical limits, and review performance calculations and airflow simulation.
Projects
Keep room information and product selections together under your project.
The equipment your space needs,
on one platform.
Suite is expanding to bring air distribution equipment, floor convectors, silencers and fans into the same engineering workspace.
Air distribution
Select grilles and diffusers for the room and operating conditions.
Floor convectors
Heating and cooling selection for your space.
Silencers
Product selection for acoustic and airflow requirements.
Fans
Fan selection for the required airflow and pressure.
Available functions depend on the application and model. More models and selection options are being added.

07 / Frequently asked questionsStart with the right questions.
What can I do with Gerhman Suite?
Suite brings product selection, performance calculation, airflow simulation and project work together. Air distribution is the currently available selection application; further applications are being developed.
Can I explore Suite without an account?
Yes. Guest access provides product browsing and available input views. Calculated results, simulation, PDF reports and project saving require an activated account.
Which diffuser should I choose for an office?
Start with airflow, ceiling height, installation position, heating and cooling conditions, and the project’s sound and comfort criteria. There is no single diffuser that suits every office. Use the available application to assess the selected model and size against these requirements.
Does Auto select compare all diffuser models?
Auto select checks sizes within the model you have selected. It should not be described as a comparison of every model in the catalogue.
What information is needed to select a floor convector?
A selection typically needs the required heating or cooling duty, water temperatures, room conditions, available dimensions and whether fan-assisted operation is required. The floor convector application is a planned addition; contact Gerhman for current product-selection support.
Can I select floor convectors in Suite now?
Floor convector selection is part of the expanding platform scope. Check the application’s availability in Suite before starting; a preview or planned module does not mean the calculation is released.
How should I choose a ventilation silencer?
Consider the required attenuation by frequency, airflow, available space, allowable pressure drop and regenerated noise. Overall sound-level reduction alone is not enough to determine the correct silencer.
Can Suite calculate silencer performance?
Silencer selection is a planned application. Until it is released, use the relevant product documentation and contact Gerhman with the acoustic and airflow requirements.
