Innovating and beautiful design, seven different sizes,high control flexibility, easy maintenance: the SkyStarchilled water Cassette is the result of an extended technical

and design development aimed at achieving the highest level

in terms of performance, silent operation and control possibilities.

The air diffuser has an highly attractive aesthetical appearance, very

innovative, and is also able to offer the best air distribution performance thanks

to in-depth computer studies and laboratory tests. The 4 smaller sizes

are designed to fit into 600x600 mm false ceiling standard modules.

The 3 bigger sizes have a dimension of 800x800 mmwhich allows the best outcome in terms of quietness

and of price/performance ratio for these high capacity models.

More than one unit can

be connected to a single control,

and the unit control panel can be installed

in a remote position that facilitatesthe maintenance operation. All the SkyStar units can be supplied in MB version. This version allows a wide range of controls, including the infra-red remote control,

which can manage one single unit or several units by using the Modbus RTU - RS 485communication protocol.

The units can be connected to the most common automatic building management systems.

Casing: made from galvanized steel with internal thermal insulation

with polyolefin (PO) foam (class M1) and external anti-condensate lining.

Control panel: made of an external metallic box

with control electronic board and easily accessible terminal board.

Air diffuser: intake grid, frame and

adjustable air distribution louvers on each side, made from ABS.

Technical characteristicsof the main components:

Fan assembly: the fan assembly,

which is mounted on anti-vibrating

supports, is extremely silent.

The radial fan has been designed

to optimise performance,

using wing profile blades with a shape

that reduces turbulence, increasing

efficiency and reducing noise.

The single air inlet radial fan is

connected to a 6 speedelectric motor with single phase230 V / 50 Hz supply, class B

insulation and integrated Klixon

thermal contact for motor protection.

The units are supplied

with 3 standard speeds connected and it is possible to change them on site if necessary.

Coil: made of copper tubes with bonded aluminium fins for maximum transfer contact.

The coils have 1, 2 or 3 rows for 2 pipe models

and 2+1 rows for 4 pipe models (the heating row is on the inside part of the coil).

For 4 pipe systems two versions are available:

• SK 04, SK 14, SK 24, SK 34, SK 44, SK 54, SK 64 supply an higher heating emission,

• SK 26, SK 36, SK 56, SK 66 supply an higher cooling emission.

The coil is not suitable for use in corrosive atmosphere or in environments where aluminium

may be subject to corrosion.

Condensate collection tray: high density ABS polystyrene foam condensate tray,

shaped in order to optimize the air diffusion, fire retardant rating B1 to DIN 4102.

Air synthetic washable filter, easily removable.

Condensate pump: float switch centrifugal pump with 650 mm of maximum head,

built into the unit and wired to the control panel on the outside of the casing.

Valve set: two or three way valves for ON/OFF operation, with pipe mounting kit

and thermostatic actuator.

The SkyStar 2 pipe models are availablewith electric heater that is controlled in place of the heating coil valve.

The electric heater is controlled in place of the hot water valve and not as integration to it.The heater is hermetically sealed and supplied inside the coil pipes

and therefore can be only factory mounted.The electric heaters of the SK 12-22-32 units are for single phase 230V supply.The electric heaters of the SK 42-52-62 units are for three phase 400V supply.

Unit with remote electric board

On request the Skystar cassettesare available with electric control panel

reachable from belowand with the electric board

that can be placed in a remote position.

The MCT version has been designed for all environments where false ceilingsare not featured or cannot be constructed.

The cover cabinet fits perfectly to the air intake and outlet diffuser, maintainingthe appealing design that defines the SkyStar series.

The water fittings can be turned to point upwards.The MCT series includes 7 models, with an installation height of up to 5 m,

thanks to the highly flexible adjustment of the air distribution louvers.All the technical specifications described on the previous pages remain the same,

while keeping in mind that the MCT series features one coil only(two pipe systems), there is no possibility of fresh air intake,

there is no possibility of additional electric heater.The MCT version features a special casing delivered in separate packaging;

this must only be fitted after having installed the SkyStar unitand completed the water and electrical connections.
