Citysphere

Spheros has developed an innovative and at the same time elegant climatic concept specially for city buses. With the new Citysphere air distribution system passengers are guaranteed a comfortable climate in the bus interior. Its low life cycle costs, together with maintenance free AC circuit, user friendliness and simple installation make the roof-top unit an efficient solution for many different applications.

The advantages:

• Weight-reduced: saves expensive fuel and reduces CO2 emissions
• Hermetically sealed, pre-filled cooling circuit: Operation with alternative refrigerants possible in future
• Patented, vehicle-independent air distribution system
• Can already be used in hybrid and other alternative bus drive concepts
• Conforms to the requirements of the future VDV guideline 236/1

Installation or retrofitting in a single day:

• Simple installation
• Hermetically sealed, pre-filled refrigerant circuit
• No pipes for refrigerant required
• No connection to air ducts necessary
• Low workshop costs
• Installation in hatch opening possible

Low life cycle costs:

• No maintenance costs for refrigerant circuit
• Substantially less added fuel consumption than a conventional rooftop unit
• Low service costs (air filter change only once a year)
