In all travel vehicles on roads and rails, healthy air circulation and climate comfort for the well-being of the occupants play an essential role.
Buses and trains are therefore equipped with special cooling systems. With a perfectly thought-out and nested piping system, well-tempered fresh air is supplied to the interior and stale air is removed.
Their air conditioner has a condenser, among other things, an evaporator, a compressor, a fan [heat exchanger] and a nested piping system.
In order to keep the branched systems continuously stable, reliable and precise measuring instruments are indispensable.
Also for the transport of food on trucks, trailers or containers, refrigeration systems are needed to maintain the cooling chain throughout the entire transport until arrival at the consignee‘s stable.
Reefer containers for worldwide trade and storage of food and non-food products such as medicines or flowers are indispensable.
The cooling of containers and trucks is achieved by a cooling unit in the cargo hold. So that these can keep a constant temperature, their refrigeration circuit is constantly monitored. Pressure and temperature gauges transmit the measured values to the control system, so that it can compensate the changed conditions.
