The ATT air-cycle climate control system is a unique, energy efficient, environmentally friendly and cost saving air-cycle system.
It is a perfect alternative to both conventional, based on the fuel consumption or electric heating, and high priced “green” technologies.
ATT air-cycle climate control systems use ambient air energy and provide heating, air-conditioning and ventilation.
They are environmentally safe as there are no freons and oils in the system, cost saving and highly efficient as 1 kW of energy input is transformed in 4 kW of green heating energy.
For heating, air-conditioning and ventilation of the passenger coaches the UPEC-engineered ATT is arranged as a monoblock unit often with the dimensions of a conventional freon air-conditioner.
The UPEC Industrial Group has developed climate control systems for different types of passenger coaches and electric train coaches.
