Test Centre

Prototype testing is an essential part of developing standard or custom solutions. The team at SNDC tests the performance of various systems, including heating, air conditioning, de-icing, pressurisation and filtration systems, in accordance with relevant standards for each sector and working environment. SNDC has two test rooms capable of reproducing a range of climate conditions (temperatures from -35 to 55 °C, humidity controls, solar rays, etc.).

Our test rooms and calibration procedures are certified in accordance with the standards of FD X 15-140 – May 2013.

Test Room - Hot Climate Chamber

HVAC System Test Centre

This room can accommodate large machines (agricultural vehicles, construction machinery, industrial vehicles, etc.) in order to carry out performance tests in even the most extreme temperature, humidity and sunlight conditions.

Heating and De-icing Test Room

The test room for heating and de-icing systems is a unique chamber capable of creating negative temperatures down to -35 °C, without needing the heat contribution from the vehicle being tested. It allows us to validate the performance and quality of both heating and de-icing systems. The cabin heating system is connected to a heat generator that reproduces the flow and increase of cooling fluid of the vehicle engine. This way, the external influences of the heat of the engine or hydraulic servers are removed.
