eComfort 300 Reversible Heat Pump for Passenger Comfort

What is the eComfort 300? The new Grayson eComfort 300 will provide advanced passenger heating and cooling (HVAC) for electric buses, utilising high-efficiency reversible heat pump technology. Its modular construction means the new range of E-Bus Heat Pump has the option to include Battery Thermal Management System with heat recovery, which minimises waste. One of the main benefits of the eComfort 300 is the innovative air island distribution for single-deck vehicles, dramatically reducing energy consumption and thermal losses. At Grayson, we offer all customers the flexibility of design and functionality to ensure we meet all system requirements without compromising on performance or quality. The C300 also has the capability to operate in 100% fresh air mode to provide passenger protection from Covid 19.
