1.1.1 Description of the unit
The Roof Top ACTIVA model line consists of a series of compact units tested for reliability. Depending
on the type of installation, models are available with cooling, heat pump and heating with gas burner.
The air intakes and outlets can be configured vertically or horizontally on all models.
Software installed in the YKN2 Open board provides electronic management for the units. The specific
configuration of each unit is programmed in this board.
In addition, a wide range of accessories is available to adapt the units to the specific requirements of
each application. Roof Top ACTIVA air conditioning units Roof Top ACTIVA series air conditioning units
can be used in extreme weather conditions.
The entire range of units uses environment-friendly, recyclable R-410A gas refrigerant.
Features of the structure
The structure of the unit is designed to drain rainwater and condensation to its exterior. The roof surface
has special contours in the evaporator area to prevent the accumulation of puddles of water. All along
its perimeter it also has a drain to prevent the water accumulated on the top panel from flowing down the
sides.
Construction features and anti-corrosion protection
All metal parts of the structure are made of galvanised aluminium steel plate.
The outdoor parts are treated with an oven-polymerised polyester paint (RAL9002), guaranteeing a
quality finish that lasts for many years. (800 H.N.S. in compliance with DIN 50021).
There are options like coils with Blue-Fin type fins or copper fins in order to adapt the product perfectly
to its environment.
Thermal/Acoustic Insulation
The inside of the evaporator area and the heating supply/accessory area are fully insulated.
The 10 mm thick insulation protects the outside surface with a sheet of reinforced aluminium with M1 fire
resistance rating in line with UNE 23727. This aluminium surface keeps friction for air passage to a
minimum and is easy to clean.
Unit base
The base of the unit is made with fixed beams that provide a solid foundation. Openings on the front of
these beams can be used to attach a crane for hoisting the unit into position during the installation
process.
The beams also have openings on the bottom to place the unit on dampers, if required.
Duct Connection
The entire line of units is prepared for connecting air supply and return ducts for downward or sideways
flow.
In the case of units to be installed with sideways ducts, an additional panel kit is required to replace the
original supply and return panels.
Air flow provided by the unit
In order to meet the precise conditions of flow and static air pressure needed in each installation, all units
include air supply fans with belt and adjustable diameter pulleys in the motor.
