BDP SERIES
1.2. - COMPONENTS
1.2.1 - CASING
The BDP Heat Pumps casing, attends especially to the following criteria: waterproof, strength,
accessibility and aesthetics.
Waterproof is achieved by coated galvanized steel panels with plastic coated on the outside
(plastic film PVC) or aluminium (see options) also thermo-acoustic protection (profiled foam) and
anticorrosive inside (5µ thickness primer paint, made of thermosetting epoxy resin and oven-dried).
Sound absorbent plate, shaped or pyramidal, inside of the panels is made of polyurethane
absorbent foam whose surface forms were made (pyramidal or shaped) to provide a higher sound
absorption than equal thickness smooth materials.
These special forms increase the collection surface noise, allowing obtaining a considerable
improvement compared to typical values of untreated materials.
The panels are joined to a extruded aluminium frame, which is terminated by plastic junctions.
The structure that is achieved is high strength and high resistance to bending and shear stresses.
Profiles torques are absorbed by the aluminium parts of the vertices of the unit.
The panels are easily removable to allow access to the inside of the machine for maintenance
or for removal of any component thereof.
The aesthetics of the BDP heat pump is achieved by coating aluminium profiles.
Heat pumps can be built in modules for later assembly on site, by transport conditions and /
or accessibility to the installation. Our Technical Department will consider the right solution in each
case.
1.2.2 – FILTERS SECCTION.
To clean the air of impurities is necessary to use filter elements studied specifically for each
application.
To extend the life of the filters is necessary that the ventilation of the machine not stop more
than 4 hours a day.
In standard models, the battery filter is assembled on the front panel of the machine, so that it
is easily replaced or cleaned. The machine also includes F6 and F8 filters according to RITE. These filters
will be adapted to the regulations of each country.
1.2.3 – COILS SECCTION
The pushed or aspired air goes through a reheat coil (hot water) and/or condenser and
evaporator coils (refrigeration gas). According to the relative temperatures of the two fluids will
produce a cooling and/or heating air.
- Reheat coil
often is used with steam or hot water, although there are other electric resistors.
Normally the resistors are made of steel tubes and rectangular fins to improve heat radiation.
