Bosch Supply Air Unit TA 450 for Water-Based Preheating

Create an optimal and highly comfortable indoor climate in your property with the Bosch Supply Air Unit TA 450. This compact and exceptionally efficient ventilation unit is specifically engineered to heat incoming supply air within balanced mechanical ventilation arrays (supply and extract). By docking the unit to a modern exhaust air heat pump, the internal heating coil is supplied by the building's most cost-effective energy source. This delivers a highly economical, uniform, and energy-efficient operation that prevents cold drafts from entering through supply vents during freezing winter weather.

Flexible Duct Connections and Versatile Placement

The Bosch TA 450 is the most versatile and adaptable supply air unit on the market. The chassis features a clever layout that allows the ventilation ductwork to be connected in any direction, making it incredibly simple to adapt to your specific on-site requirements. The unit can be mounted directly on top of an exhaust air heat pump from ranges like the Compress series, mounted adjacent to the heat pump, or placed freestanding on a utility shelf. For ideal acoustic isolation, mounting on a vibration-dampening surface is recommended.

Fully Equipped and Reliable Architecture

The unit is delivered completely assembled, containing an integrated 5-speed fan module, an efficient air filter, and a high-performance copper water-heating coil. To guarantee ultimate operational safety, the system is factory-equipped with internal protection circuitry that guards against excessively low heating coil temperatures, strictly minimizing the risks of frost expansion damage during winter peaks. If required, the unit can easily be supplemented with an external duct heater, room thermostat, and sensors for even more precise temperature regulation.

Compact Build Tailored for Residential Demands

Featuring a standard width of 600 mm and a shallow depth of just 290 mm, the Bosch TA 450 occupies a minimal footprint inside utility areas or mechanical plant rooms. Despite its compact external dimensions, the fan capacity effortlessly manages the total ventilation demands of a standard detached family home. The light weight of 16.3 kg simplifies on-site handling during installation, while the recessed spigots guarantee a clean, tight, and professional finish at the duct joints.
