Simply efficient

With Air Flux 5300A (C), Bosch is offering you a range of units for comprehensive air conditioning of buildings. At its core is a scroll compressor with vapour injection. An intelligent energy management system automatically adjusts the temperatures in the refrigeration circuit for maximum comfort and high energy savings.

Simply flexible

Copper piping lengths of up to 1000 m and a height difference of max. 110 m between the indoor and outdoor units offer you a flexible project design and simple installation. The installation process is further simplified by the automatic refrigerant filling, automatic refrigerant charge and simple data check via the control box.

Simply reliable

A large number of automatic checks ensure that it operates reliably on a day-to-day basis. Automatic compressor backups and emergency mode functions provide operating reliability for your cooling demands in your building. Different priority profiles make it easy for you to take into consideration the different requirements in the building.

Simply quiet

Multi silent mode with 11 different options for "night silent mode", "silent mode" and "super silent mode" allows to reduce the sound levels where needed. The new anti-vibration technology, together with soft metal pipes for extracting and injecting at the compressor, allow for a low noise level. This is supported by asymmetrical fans that emit an unchanging tone. An excellent climate without noise pollution – with Air Flux from Bosch.

Simply plan

Different unit sizes and maximum copper piping length of up to 175 m simplify planning. In addition, Bosch uses the intelligent Air Select planning tool to support you: It is extremely easy to use and helps you determine your optimum system configuration in no time.

Simple project management

You can rely 100 % on Bosch – for project management too. Bosch has a dense network of service outlets and sales partners, who will support you any time you have questions and will ensure that your plans are implemented smoothly.

Simple service

The sophisticated technology reduces the need for service. This makes it a worthwhile investment for operators and improves the availability of the system. Self-cleaning functions for clearing dust and snow extend the service life and reduce maintenance costs. Furthermore, the ease with which you can call up the unit's history helps you complete the service work in a shorter time.
