SENSIRA FTXC-E
Living-room capacity at Sensira value
This is the 18 000 Btu Sensira in the new-generation FTXC-E series, pairing the FTXC50EV1F indoor unit with the RXC50EV1 outdoor unit. It is the size for living rooms, open-plan kitchens and large main bedrooms.
It suits rooms of up to about 36 m², in the same compact 770 mm indoor unit as the 9 000 and 12 000 Btu Sensiras.
At its rating it delivers 5.10 kW of cooling (about 17 400 Btu/h) and 5.62 kW of heating, with a Daikin network adaptor built in for app control.
Proper Daikin inverter cooling and heating for the rooms you use, without paying for features they will rarely need.
EFFICIENCY
A++ cooling across a wide inverter range
Daikin rates the Sensira 18 000 at a seasonal efficiency of 6.5 (SEER, A++) in cooling and 4.4 (SCOP, A+) in heating, rising to 5.3 (A+++) on Daikin’s hot-climate heating scale. At its rating it draws 1 550 W to deliver 5.10 kW of cooling, an EER of 3.29.
The inverter varies its output between 1.37 and 6.20 kW in cooling and between 1.36 and 6.60 kW in heating, so it can push past its rating on a very hot afternoon and slow right down once the room is comfortable.
The outdoor unit measures 615 × 845 × 300 mm and weighs 39 kg.
DESIGN
A cleaner look for the new generation
Daikin redesigned the Sensira for the FTXC-E series. The indoor unit takes its lines from Japanese origami: a sharp crease runs through the centre of the front panel and folds into a smooth, flat surface, with defined edges where the older Sensira was rounded.
A single, minimal LED indicator replaces the busier display of earlier models, so the unit sits quietly on the wall of a modern room.
The 18 000 Btu indoor unit measures 288 × 770 × 234 mm and weighs 9.5 kg, so a living room gets the extra capacity without a larger unit on the wall.
WHERE IT WORKS
Made for living rooms and open-plan spaces
A living room is where an aircon runs longest, so the inverter matters most at this size: it throttles down through a long afternoon instead of cycling on and off.
On its quietest fan setting the indoor unit runs at 30 dBA, with vertical auto-swing spreading the air through the room and Powerful mode for a fast cool-down when you come home.
For a living room in use all day, the Perfera 18 000 Btu is quieter (27 dBA), more efficient across the season and adds Comfort+ twin flaps and air purification.
COMFORT AND FILTERS
Quiet, filtered, and easy to live with
A Saranet filter catches airborne dust as air enters the unit, and a titanium apatite deodorising filter takes up everyday odours. Both are there to keep the air the Sensira circulates cleaner; neither turns it into an air purifier, for which see our air purifiers.
Vertical auto-swing spreads the air through the room. Sleep mode eases the temperature through the night so the room does not end up too cold or too warm by morning, and Powerful mode gives a short boost when you come home to a hot room.
Econo mode caps the power draw, which helps when the aircon shares a solar or backup supply with the rest of the house, and the self-diagnosis function tells a technician where to look if something goes wrong.
MADE FOR SOUTH AFRICAN POWER
Daikin South Africa stock, ready for load-shedding
This unit is supplied through Daikin South Africa for a 220–240 V single-phase supply, so the local Daikin warranty applies and parts come through Daikin’s South African network. Air conditioners brought in by private importers are not always covered here.
Auto-restart returns the unit to its previous settings when the power comes back after an outage, so there is no reaching for the remote after load-shedding. At about 1.55 kW in cooling, a 5 kW inverter carries it with room to spare.
A Daikin network adaptor is built in, so the Sensira connects to Daikin’s Onecta app out of the box and can be controlled from your phone at home or away. An infrared remote is in the box.

How the Sensira 18 000 Btu sits against the alternatives
The Daikin Perfera 18 000 Btu is the premium alternative. It is rated at 5.0 kW of cooling against 5.10 here and a SEER of 7.80 against 6.5, draws 1.36 kW against 1.55 kW, runs at 27 dBA on silent against 30, and adds Comfort+ twin flaps, a two-area motion sensor and Flash Streamer. In a living room used most of the day, the Perfera is the more comfortable and economical unit; for evening use, the Sensira is good value.
For a room under about 30 m² the Sensira 12 000 Btu is enough; for a larger open-plan space, the Sensira 20 000 Btu.
Where several rooms need cooling and there is little space outside, a multi-split system runs several indoor units from one outdoor unit.
Questions we are asked about the Sensira 18 000 Btu
Up to about 36 m² with a standard ceiling height: a living room, open-plan kitchen and lounge, or a large main bedroom. A high ceiling, big sun-facing windows or a hot roof above add load; in that case look at the Sensira 20 000 Btu.
At its rating it draws 1 550 W in cooling and 1 515 W in heating, and less once the room is at temperature, because the inverter slows the compressor down.
Yes. At about 1.55 kW in cooling, a 5 kW inverter carries it with room to spare, and Econo mode can cap its draw further. Auto-restart brings it back to its previous settings once the power returns.
The indoor unit runs from 30 dBA on its quietest setting to 47 dBA on high in cooling. The outdoor unit is rated at 51 dBA.
Yes. The new-generation Sensira has a Daikin network adaptor built in, so it connects to the Onecta app without an add-on module. The infrared remote is also supplied.
No. A split system has to be installed by a qualified installer, with copper piping, cabling and a bracket or base for the outdoor unit. Our installers cover the major South African cities and quote separately. The units can sit up to 30 m apart (20 m in height).
Not in the way a purifier does. The Saranet filter catches dust and the titanium apatite filter deodorises, but there is no Flash Streamer or HEPA stage. For allergies or smoke, look at the Perfera, which adds Flash Streamer and a silver allergen filter, or a dedicated air purifier.
