HVAC

eCO2rail

eCO2rail is the name of a family of innovative ecological HVAC air conditioning systems able to respect the environment throughout the use of CO2 carbon dioxide (R744) as a refrigerant gas, suitable for installation on rail/metropolitan rolling stock also in countries with a warm climate such as Italy, Spain, Portugal and Greece.

30% reduction of the annual energy consumption

CO2 HVAC systems are able to operate with reverse cycle (Heat pump) with efficient and effective heating performance in winter time even at low temperatures without the need to use heaters: in traditional HVAC systems, in heating modality, the in- convenience of a drastic drop in performance around zero degrees of ambient temperature requires the need to install electrical resistors (heaters) to achieve the performance required by the specifications.

F-GAS Regulation compliance

minimum possible GWP = 1

Certainty of refrigerant gas availability

for the present and the future not subject to market changes (it's not possible to guarantee the availability of traditional gases in future years )

Reduction of maintenance costs

Carbon dioxide has: cheaper cost (about 1 €/kg) than any other refrigerant gas and the certainty of maintaining the price in the future, because of its widespread use.

Competitive advantage

Being sustainable, green, environmentally conscious, nowadays is undoubtedly a competitive advantage; Green Marketing has become a new strategic lever thanks to the growing sensitivity of users/ consumers to the world of eco-sustainability.

System Split Chiller

eCO2rail-SCAB1

eCO2rail-SCAB1 is a split-type chiller system for application in driver’s cab. The Split configuration of the system allows to install the chiller unit outside the cabin and the GTA inside the cabin under the bench. Thanks to the small size of the chilled water supply system, this system is particularly suitable for cabins with little available space.
