NOISE
The hum above the tables
Sheet metal and conventional motors transmit vibration. The EPP casing and DC Inverter motor of Black Box cut noise by up to 3÷6 dB(A).

01 · WHY BLACK BOX
Conventional hydronic cassettes have three flaws. Black Box removes all of them.
In restaurants, hotels and offices the cassette sits right above people's heads: you hear it, you see it and sometimes it drips. Black Box is not an evolution: it is a new design, conceived from a different point of view: comfort and the look of modern ceilings.
CONDENSATION
Stains on the suspended ceiling
Metal structures form condensation when the air is humid. EPP has a lower thermal transmittance than any insulated metal: no external condensation even at 90% humidity.
CODES AND OPTIONS
One model for every need
Capacities, versions and accessories multiply product codes and errors. Black Box is a single configurable code, with many options already included as standard: condensate pump, Wi-Fi, Modbus and much more.
02 · WHAT IS A HYDRONIC CASSETTE
A ceiling fan coil that heats and cools with water, not gas.
A hydronic cassette, also known as a cassette fan coil, chilled water cassette or ceiling fan coil unit, is recessed into the suspended ceiling and receives hot or chilled water from a heat pump, boiler or chiller. The fan passes air over the coil and delivers it into the room: it heats in winter, and cools and dehumidifies in summer.
Unlike a cassette air conditioner, which is a DX split system running on refrigerant gas with its own outdoor unit, a hydronic cassette uses the building's water system: no refrigerant gas in occupied spaces and a single heat source for heating and cooling.

03 · THE 7 SECRETS
Seven design choices that make it unique.
Every detail of Black Box answers a real problem faced by those who design, install or live in the spaces. The seventh is the one almost nobody checks.
01
One code, endless configurations
From 1 to 6 kW of heating capacity in a single model, with configurable flow rates and versions. Fewer codes in stock, more flexibility, zero ordering errors.
02
Silent even at full power
Aerodynamic design and DC Inverter motor: up to –6 dB(A) compared with the main competitors. From 19 dB(A) at minimum speed.
03
Performance without compromise
Golden fins coil and optimised control: up to +20% capacity compared with conventional cassettes. The golden fins treatment improves resistance to oxidation and long-term durability.
04
Coanda effect or 4-way diffusion
The air jet clings to the ceiling and travels twice as far: double throw thanks to the Coanda effect. Even distribution, perceived comfort, no draughts.
05
Quick installation, everything as standard
Condensate pump, automatic air vent, spirit levels, Wi-Fi and Modbus: what others sell as options is included here.
06
Advanced filtration and integrated lighting
Antibacterial and anti-COVID filters, Cold Plasma and electrostatic. Panel with display and backlighting on request.
07
Customisable calculation software
Adapts Black Box performance to the actual system conditions: water temperatures, air, speed. From design to comfort in a few clicks.
04 · BEYOND THE STANDARD, INCLUDED
What others sell as options is standard here.
EPP casing
Maximum thermal insulation and minimum noise emission. Internal fluid-dynamic design that is not possible with sheet-metal structures and right angles. No external condensation even at 90% humidity.

Technopolymer radial fan with latest-generation, low-consumption DC Inverter motor: from 4 to 54 W.
Golden fins coil
High efficiency, resistant to impact, oxidising agents and dirt.
Automatic air vent

05 · PANELS AND DIFFUSERS
The Coanda panel: the cassette that furnishes the ceiling.
The air jet clings to the ceiling through the Coanda effect and spreads evenly, with no draughts on people. The panel has a built-in display with a Wi-Fi chip compatible with the App Tuya and can be backlit.
For those who prefer a classic style there is the 4-way panel in UV-resistant white ABS, with motorised or manual flaps and LED display.

09 · COANDA EFFECT
The air follows the ceiling.
Comfort reaches the whole room.
The aim is to distribute the airflow and promote mixing, reducing direct jets on people and temperature differences in the room. With the Coanda panel the throw doubles; for the effect to work, the air must leave at the correct velocity, above 2.5 m/s, so it stays attached to the ceiling and does not "rain down" on those below.

FREQUENTLY ASKED QUESTIONS
Hydronic cassette fan coils: answers to the most searched questions.
What is a hydronic cassette?
It is a ceiling-recessed fan coil unit that heats and cools with water instead of refrigerant gas. Hot or chilled water comes from a heat pump, boiler or chiller, flows through the finned coil, and a fan delivers the treated air into the room. It is also called a cassette fan coil, chilled water cassette or ceiling fan coil.
What is the difference between a hydronic cassette and a cassette air conditioner?
A cassette air conditioner is a split (DX) system: refrigerant gas runs through the ceiling and it needs a dedicated outdoor unit. A hydronic cassette uses water, connects to the building's system and provides both heating and cooling from the same heat source. No refrigerant gas in occupied spaces, no extra outdoor units and one system serving the whole building.
How does a hydronic cassette fan coil work?
The fan draws air in through the centre of the panel, passes it over the coil where the water flows and returns it to the room through the side outlets. On Black Box, the Coanda panel makes the air jet cling to the ceiling, so the air spreads evenly without draughts blowing directly onto people.
Does it work with a heat pump?
Yes, it is the ideal match. Black Box delivers 8.3 kW in heating with water at 45/40 °C and 6.67 kW in cooling with water at 7/12 °C, at maximum speed. Working with low-temperature water makes the heat pump more efficient.
How quiet is it?
In the version with the 0÷10 V modulating motor, sound pressure starts at 19 dB(A) at minimum speed and reaches 32 dB(A) at maximum. The EPP structure absorbs vibration: up to 3÷6 dB(A) less than conventional cassettes.
Does it fit a 60×60 suspended ceiling?
Yes: the unit is designed for the standard 600×600 mm ceiling grid module and is completed with the Coanda panel (650×650 mm) or the 4-way panel (711×711 mm). The built-in spirit levels help you install it perfectly level.
Does it need a condensate drain?
In cooling mode, yes, like any fan coil. Black Box comes as standard with a condensate pump with a lift of over 0.5 m and an auxiliary drip tray, so the drain can be run even where there is no natural fall.
Can it be used on 2-pipe and 4-pipe systems?
Yes. With the 2-way or 3-way valve kits it works on 2-pipe systems; with the 3-way valve for 4-pipe systems it can heat and cool with two separate circuits.
How much power does it use?
The DC Inverter motor draws from 4 W at minimum speed to 54 W at maximum. The optional active filters use 1.5 W (Cold Plasma) and 1.6 W (ESP electrostatic).
Can it be connected to the building BMS?
Yes: Wi-Fi with App and Modbus are standard across the range. Using the Modbus protocol from the control board, up to 198 units can be managed, including in master/slave configuration.
What is the Coanda panel and what are its benefits?
It is the Black Box diffusion panel that uses the Coanda effect: the outgoing air jet clings to the ceiling and flows along its surface instead of dropping straight down. The benefits: double throw, so the air travels twice as far and covers the room better; even temperature distribution, with no hot and cold spots; no direct draughts on people seated under the cassette. For the Coanda effect to work, the air must leave at the correct velocity, above 2.5 m/s: this keeps the jet attached to the ceiling so it does not "rain down" on people. In addition, the Coanda panel has a built-in display with Wi-Fi, comes in 4 colours (Silver, White, Black, Sand) and can be backlit on request.
How much does a hydronic cassette cost?
It depends on the configuration: panel, filters, valve kits and type of control. That is why we prepare the technical selection with the Black Box calculation software, based on the actual conditions of your system, and send you the quote, free of charge and with no obligation.
How many square metres can it serve?
It depends on the room loads: insulation, glazing, occupancy, use. As a reference, one unit delivers up to 6.67 kW in cooling and 8.3 kW in heating. Our technical department calculates the correct number of units with the selection software.
