Product Description

Rooftop Packaged Unit is the quickest and most competitive solution for climate control in large buildings. The cooling or thermal energy needed for climate control is produced locally - only when required - and sent to the serviced areas via a suitable air distribution and diffusion system, consisting of ducts and diffusion terminals (outlets, anemostats, nozzles, etc.). Amrta rooftop packaged Air Conditioner is highly efficient because they do not use intermediate fluids. They offer a very high performance thanks to systems such as active thermodynamic recovery.

Application areas

● Large and light commercial buildings (Retail, Airports, Restaurants, shops, petrol stations-)
● Cinemas, Theaters
● Industrial buildings and Logistic centers

Why this choice?

● Energy efficient solution
● Cost effective package for fast and easy installation
● Multiple heating options available
● Fresh air control and free cooling management

● Wide choice of communication interfaces
