1. INTENDED USE

BRAVA heating and cooling units are intended for use in compartments requiring application of
devices with an aesthetic and innovative appearance, such as:

» shopping centres,
» discos,
» showrooms,
» churches,
» sports and entertainment halls,
» car showrooms,
» as well as locations, where conventional heating units are used, i.e. in warehouses, production

premises, workshops, greenhouses, etc.

The units cannot be used in the compartments with humidity exceeding 90% and air
dustiness of more than 3 mg/m3.

The units are intended for use in compartments with the height not exceeding 5m.
The premises can be served by one unit or more.

2. DESIGNATIONS

HEATING AND COOLING UNIT BRAVA-II

Number of exchanger rows I; II

Optional automatic equipment set:

» 1 unit: AB1-BRAVA

The unit, intended for heating function only, is delivered with I or II row heat exchanger. Optional
cooling function is available only with II row heat exchanger.

3. DEVICE DESCRIPTION

The unit comprises:

» highly-efcient axial fan (~ 700 rpm);

The units can have fans tted with electronically commutated motors.

» ring n single- or double-row heat exchanger.

Connections on units have female threads.

Fin heaters can be supplied with heating medium with the temperature of up to 150OC
and the pressure of up to 1.5MPa.

There is a risk of freezing the heating medium in the heater in rooms with temperature
below 0OC.

This risk can be reduced by using non-freezing heating or cooling media.

» housing made in high-quality plastic, with ve-way air diffuser. The diffuser design provides

protection against self-acting displacement of the blades.

5. TRANSPORT

BRAVA units are delivered completely covered in polyethylene lm to provide protection against
contamination and weather.
The unit is delivered with the Product Booklet (instruction manual).

The units should be transported on one level with spacers so as to prevent any
