General Description

Double is a ducted fan coil unit with integrated a cross-flow heat recovery unit for air exchange in small/medium rooms allowing an energy recovery.

Unit Description

Self-supporting frame in 1 mm galvanized steel internally insulated with sound absorbing insulation material. It consisting of a high-efficiency heat exchanger, a heat

exchanger, three centrifugal fan units with 3-speed asynchronous motor or high efficiency variable speed ECM motor and filters placed in the air intake sections.

Installation

The small size of the unit allow the installation ducted ceiling.

Application

Residential and Commercial.

Regulation

Electronic microprocessor controller with dedicated software. Room temperature control with temperature sensors and outdoor air flow with air quality sensor. Remotable

user control panel. Modbus remote management.

The 10MK units are designed to reduce energy consumption in installations where fresh air is introduced into the building. The extract air is used to pre-heat the incoming fresh air and thus allows for considerable energy savings. The heat exchange reclaims up to 50% of the energy contained in the extract air which would be otherwise lost.

All the unit panels are removable for easy inspection and maintenance. The 10MK series are produced in 6 sizes with an airflow range of 500 to 300m3/h.

The basic units are produced in galvanized steel or, on request in pre-plastified steel RAL 9010 (white) colour for units in view within the room. The units panels are internally lined with 10mm thick thermal/acoustic insulation (other thicknesses available on request).

Fan Section

Supply and extract fans are DIDW, forward curved, direct driver single phase with 2 pole motors ( for units 10MK1 and 10MK2) or with 4 pole motors for the rest of the range.

Heat Exchanger

• Static type cross flow heat exchanger. Aluminium plates sealed in an aluminium frame.
• Steel condensate pan with drain connection.

Filters

Easily withdrawable polyester filters 86.5 efficiency Am and G3 according to EN 779.

Fresh air handling unit characterized by high efficiency and complete autonomy of operation (does not requires heat transfer fluids produced by other plant components) and extended operating limits (both summer and winter) due to pre-treatment ensured by the rotary heat recovery unit and the modulating compressor (inverter), which brings the operating temperature of the refrigerant circuit within safe values.

The unit

• Different heat recovery systems in a single unit:
• Sensible and latent “sorption” heat recovery
• Active thermodynamic heat recovery

• Desuperheating heat recovery
• Inverter compressors with EC motor
• Variable speed fans with EC motor
• Specific electronic control
• Sandwich panels 60mm with thermal break
• Electronic filtering
• Versions for cold climates (-30°C b.s.)
• Also suitable for hot climates (52°C b.s.)
