In mechanically controlled air suspension systems, the device that measures the level also controls the air spring. With ECAS, an electronic system takes over control, regulating the air springs by means of solenoid valves informed by measured values from Sensors.The Solenoid Valve can adjust pressure in all of the air bags or in individual air bags. This allows ECAS to compensate for inclinations caused by unbalanced loading in the front, rear, left side or right side of the bus.

Heat exchangers are used to exchange heat between two fluids. Plate heat exchangers are high performance components and provide a high level of efficiency combined with compact dimensions and low weight. Their efficiency reduces the amount of cooling water required for heat transfer which results in low operating costs.
Features
Plates and connections are manufactured from stainless steel to AISI 316, vacuum brazed with cooper. The special moulding of the plates produces the turbulent flow necessary for effective heat transfer and provides the plate heat exchanger with a high level of mechanical strength.
Operating Details
Medium:
Water glycol
HFC operating fluids
Water
Oil
Contamination
The quantity of particles in suspension should be less than 10 mg/l, particle size <0.6mm
Thread like particles cause a rapid rise in pressure drops.
Temperature range:
10C to 225C (freezing point and boiling point must be taken into consideration)
Pressure:
Max 45 bar up to 225C, testing pressure 60 bar.
Corrosion
The following limits refer to a pH value of 7
Free chlorine. CL2<0.5ppm
Chloride ions CL
<700 ppm at 20C
