What is a tri split cassette?

The tri split cassette is a system in which a single outdoor unit feeds three cassette indoor units, recessed into the false ceiling. It is the solution designed for those who want to air-condition three separate rooms, such as offices, waiting rooms or commercial premises, while keeping a single unit outside and a minimal visual impact inside.

Why choose cassette units

Cassette units diffuse the air on several sides thanks to the motorised louvres, so the temperature stays even throughout the room without cold or warm spots. They are perfect for large rooms with a lowered ceiling, because they sit flush with the false ceiling and are barely visible. If you need the same look for a single room, consider a single split cassette.

A single unit for three indoor units

With a tri split you connect three splits to a single outdoor unit: you reduce clutter on the balcony or façade and simplify installation compared with three separate systems. If the three rooms are of different sizes, you can pair units of different power, so as to size each room on its real square metres.

How many BTU do you need for each room?

The power of each cassette unit is chosen according to the square metres of the room it must serve. As a general guide:

  • 9000 BTU: rooms up to about 25 m².
  • 12000 BTU: rooms from 25 to 35 m².
  • 18000 BTU: rooms from 35 to 50 m².
  • 24000 BTU: very large rooms and open spaces.

The power of the outdoor unit must be consistent with the sum of the three indoor units. For other types of ceiling units you will also find the cassette air conditioner family.

The available brands

In the catalogue you will find the leading manufacturers with official warranty and available spare parts: TCL, Hisense, Daikin, LG, Haier and Samsung. Prices for complete systems start at about 1540 euros and go up to the highest-performing configurations, so you can find the right solution for every budget.

Tri split cassette or other configurations?

If you prefer the classic units mounted high on the wall, consider a tri split wall-mounted system. If instead you want to hide the indoor units completely in the false ceiling, you can opt for a ducted system. To design the tailored combination of indoor and outdoor units, it helps to start from the multisplit configurator.

Tax incentives and reduced VAT

The purchase and installation of a heat pump system may qualify for tax incentives where applicable, such as reduced VAT for renovation work. The conditions depend on the type of work, so it is best to check the current requirements. Discover all the promotions in the offers section or browse the full range of air conditioners.

Frequently asked questions

What is the difference between tri split cassette and wall-mounted?
Only the shape of the indoor units changes. The cassette ones are recessed into the false ceiling and diffuse the air on several sides, while the wall-mounted ones are fitted high on the wall. The principle is the same: three indoor units connected to a single outdoor unit.
Can I use units of different power in the same system?
Yes. In a tri split you can pair cassette units with different BTU, so you size each room on its real square metres. It is important that the sum of the three units is compatible with the power of the outdoor unit.
Do cassette units require a false ceiling?
Yes, cassette units are designed to be recessed into a false ceiling, where only the supply grille stays in view. For this reason they are widely used in offices, shops and commercial premises with lowered ceilings.
How many BTU do you need for each cassette unit?
It depends on the square metres of each room. For a well-insulated room up to about 25 m², 9000 BTU is usually enough, while for rooms from 25 to 35 m² it is best to move up to 12000 BTU.
Does a tri split cassette also heat in winter?
Yes. Inverter heat pump systems produce heat efficiently even at low outdoor temperatures and can complement or replace the radiators in the three rooms served.
Can I get reduced VAT?
In many cases yes, when the installation is part of renovation work. The application of reduced VAT and incentives depends on the type of work and the documentation, so it is best to check the current requirements.
