Residential chillers and heat pumps

BRA2 0021 – 0061

Chillers, air source for indoor installation Cooling capacity 5,74 – 15,7 kW

BRA2 0021 - 0061

BRA2 is the Climaveneta range of air-cooled liquid chillers with R410A refrigerant. They are fitted with hermetic Scroll compressors and Full Floating technology. The latter is an intelligent electronic unit providing the perfect answer to residential market requirements: compactness, ease of installation and quietness. The unit are designed for indoor installation with radial plug-fan as standard equipment. The air outflow can be ducted in vertical or horizontal. 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.
