FAN COIL UNITS

crc

In line with innovative trends and modern industrial design, the Carisma fan coil range meets today’s demanding requirements of performance, size, acoustics, low energy, ease of installation and maintenance.

The Carisma fan coil unit has been designed around a platform of models, versions and accessories, all of which have been independently tested and certified by Eurovent.

Designed around 5 different versions, the extensive range includes wall and ceiling mounted units, exposed or concealed with either tangential or centrifugal fan options, delivering one of the most versatile ranges of fan coils on the market today.

All CRC fan coils with centrifugal fans are equipped with electric motors which dramatically reduce electrical consumption of up to 40% comparative to previous models, with 6 speed motors as standard offering greater flexibility in the selection of products.

New market trends have also led to an extension of the four pipe model which now has a two row LTHW battery giving improved outputs at lower flow and return temperatures.

As a special option, the Carisma range can be fitted with the Crystall patented electrostatic filter featuring a class D rating according to standard UNI 11254 which equals a traditional mechanical filter of up to F9 without dramatically affecting static pressures.

A full range of control options is available including the Free patented wireless control offering greater flexibility in the installation of units, with the highest precision in monitoring and maintaining the desired comfort conditions.

The Carisma model is complemented with a full range of options and accessories covering items such as electrical heating battery, air inlet/outlet diffusers and condensate pumps.

The CRC series with centrifugal fans comes in 5 versions, 9 sizes, 18 models with single coil and 27 models with double coil, with air flow-rates ranging from 100 to 1500 m3/h, heat outputs from 1 to 17 kW and cooling capacities from 1 to 8 kW

maestro

The MAESTRO fan coil units are for concealed installation and connection to a duct system. They supply a consistent air flow with static pressure up to 150 Pa. The MAESTRO Fan Coil Units are manufactured in 5 sizes for hot water supply (11-42 kW) and chilled water supply (4-16 kW).

RADIATORS

ottimo1


The first die-casted radiators in aluminum! Design studio Meneghello&Paolelli restyled the classic die-cast radiator to give it brand new looks, with strong design/artistic connotations. Besides a refurbished appearance, Ottimo stands out from the technological standpoint, with better than average thermal efficiency and performance.

The Classic is available in three different connection types (K / VK / M). D ie removable with a handle cover facilitates cleaning and provides lasting comfort and hygiene.

Classic K allows - through the 4 side sleeves - a mutual and equilateral connection and thus comes mainly in renovating old buildings for use.

Classic VK addition to the lateral connection with integrated distributor facilitates the connection of the "bottom". So the radiator takes place both in the renovation of old buildings as well as in the newer part of his place.

Classic M brings the innovative Centara technology used. The built-in heater manifold block contributes to a number of advantages for a comfortable climate in the building and allows obtaining an optimal indoor climate with the lowest possible energy consumption.
