For cool calculators

• As a retrofit the Citysphere can be installed, for example, in an existing roof cut-out: no elaborate and risky changes to the skeleton of the bus are necessary (applies to Class 1 2001 / 85 / EG buses after 03/2005). The simple installation kit permits a retrofit under normal conditions in a single day.

• All components of the cooling circuit are accommodated within the housing: no condensor connection in the engine compartment and no refrigerant ducts in the bus interior.

• The Citysphere ist hermetically sealed and pre-filled with refrigerant. That makes the system's cooling circuit completely maintenance-free and ensures low operating and service costs.

• The automatic control unit will operate up to four systems, is outside temperature-regulated and diagnosis-capable via a control device.
