Commercial air handling unit SENSE CX

indoorcompactfor ceiling

Short description
Decentralised compact air handling unit for ceiling installation, designed for classrooms, offices and meeting rooms. Available in three sizes with air flow up to 1000 m3/h, featuring counterflow heat recovery and optional enthalpy core.

Key features

• 3 sizes — up to 1000 m3/h
• Counterflow plate heat exchanger (aluminium or enthalpy), EUROVENT-certified
• Integrated CO2 sensor for demand-controlled ventilation
• Quiet operation: 35 dB(A) at 1 m (nominal speed)
• Energy-efficient EC motors and monitored filters

Efficient casing with dual insulation
The compact monobloc casing incorporates a dual-layer insulation system for thermal and acoustic performance. Outer panels: 20 mm mineral wool sandwich (λ = 0.042 W/mK). Inner layer: 30 mm melamine foam (λ = 0.034 W/mK). Back-draught shutters at outdoor and exhaust connections prevent unwanted airflow. Maintenance access via a gas-strut-supported service door.

Quiet and efficient EC fans
Backward-curved centrifugal fans with EC motors provide high efficiency and low noise. Fans are statically and dynamically balanced, fitted with maintenance-free ball bearings and thermal motor protection. Integrated pressure monitoring at fan inlets enables precise airflow control.

Modular heating and cooling options
Pre- and post-heating, plus cooling, are available in electric or water-based variants. Electric heaters use SSR switching and safety thermostats with manual reset. Water coils feature copper tubes and pressed aluminium fins, rated to 100 °C and 1.6 MPa, with integrated freeze protection. Cooling versions include a condensate tray with drainage; optional condensate pump available.

Counterflow heat recovery
Removable aluminium or enthalpy counterflow plate heat exchanger, EUROVENT-certified, with an integrated bypass damper driven by a modulating servo for accurate airflow control. Condensate is managed via an exhaust-side tray and dedicated drainage; optional pump for condensate removal.

Filters & air quality
Supply filter class: ePM1 60%. Extract filter class: Coarse 60%. Filter differential pressure is monitored by transmitters; filters are accessed and replaced via bottom service doors.

Control system
Fully integrated control with 3.5" touchscreen supporting manual, CAV and DCV (demand-controlled ventilation) modes. Offers intuitive operation, automated energy-saving sequences and precise temperature regulation.

Design & application
Designed for under-ceiling air discharge using the Coanda effect to ensure even fresh air distribution. Suited for decentralised ventilation in classrooms, offices and conference rooms; suitable for new and existing buildings.

Operating conditions
Operation in ambient temperatures from +5 °C to +40 °C. When installed in ducting the unit is IP20. Intended for standard atmospheric air free of dust, grease and corrosive contaminants.
