Examples of applications

Cable Car Cabin

In designing and manufacturing this complete system, our design team has produced a highly innovative solution. It is the first single-voltage kit, running on 48 V, includes all the necessaryy components, can be controlled electronically and allows the drainage of condensates.
Electronic controls: a microcontroller has been developed to allow control over all units (air conditioning and heating functions) and return error codes directly from the control station, allowing the kits to be controlled either individually or simultaneously.
Drainage principle: a deflector system is included to prevent the rejection of condensate water in the cabin for improved passenger comfort (patented system).

Application HYDRAUTAN


This vehicle is used to transport people in tunnels under construction. To address all the requirements for this vehicle, our engineering team was able to install a compact solution, the HYDRAUTAN. This stand-alone air conditioner, driving by a hydraulic motor, is able to deliver a high cooling capacity and includes all the components of an HVAC system in a single unit.
