Residential chillers and heat pumps

BRAT2 0021 – 0121

Chillers, air source for indoor installation Cooling capacity 5,74 – 31,7 kW

BRA2 0021 - 0061

BRAT2 is the Climaveneta range of air-cooled chillers with gas R410A. It is an outdoor unit with axial fans, hermetic Scroll compressors and Full Floating technology. The latter is an intelligent electronic unit providing the perfect answer to residential or commercial market requirements: compactness, ease of installation and quietness. The units can be arranged to satisfy a wide range of system requirements: with base or with integrated EC inverter pump low consumption, ErP2015 complied.

Full Floating features

The new generation electronic controller allows to manage the chiller by using the Full Floating technology, designed by Climaveneta for improving the system´s efficiency for the fans (Floating Fans), for the circulating pump (Floating Flow) and finally for the working temperature (Floating Setpoint). This also allows to achieve all the following benefits: improvement of efficiency in both standard and extreme conditions, much lower operating noise in part load conditions, lower installation time, lower time for system set-up, broader operating limits, faster transient after defrosts.
