Comfort in every room. A system shaped around the operation. We combine FujiTherma air-distribution, temperature-control and operating-management features in a VRF solution suited to your building.
SCA Engineering is a dealer for FujiTherma VRF air conditioning systems. Our Istanbul-based team handles survey, selection, design, installation and commissioning across the Marmara region.
Why FujiTherma?
Precision control as room demand changes
X3 temperature sensing and a 2,000-step electronic expansion valve help manage refrigerant flow around changing indoor loads. We pair that control with calculated capacity and suitable sensor placement. VIP mode can prioritise up to five indoor units, subject to the system arrangement; it does not increase outdoor-unit capacity.
Explore X3 controlSofter air distribution around occupants
Compatible four-way cassettes offer independent vane adjustment and breeze-panel options. Compatible motion sensors can support airflow and occupancy management. We select the unit, panel, sensor and controller together and coordinate them with desks, seating and room use.
Explore cassette air distributionThermal management for control electronics
X3 refrigerant cooling removes heat from the electrical control box, with a temperature sensor supporting monitoring. We assess the electronics’ thermal management alongside outdoor-unit airflow and service clearances. The feature does not remove the need to prevent hot discharge air returning to the intake.
Share operating duty across compatible equipment
X3 runtime balancing adjusts the operating sequence between compatible outdoor modules and compressors. It supports a more balanced sharing of running time. We select the combination against simultaneous loads and include maintenance planning; rotation does not guarantee a fixed equipment life.
Consider faults before they occur
The X3 catalogue describes outdoor-unit, compressor and fan backup scenarios. Compatible combinations may provide emergency capacity under specified fault conditions. Compressor scenarios depend on suitable two-compressor equipment or module combinations; fan scenarios require a two-fan unit. Remaining capacity, fault type and access all matter.
Choose the scale around the building
A Series · compact VRF
The main 8.0–22.4 kW WDCHAX range serves compact home, office and shop applications with single-phase options. We select electrical supply, location and the indoor-unit combination together. The separate 12 HP THX335WDCHX table requires its own model data.
View A SeriesX3 Series · modular VRF
8–28 HP single modules provide the starting point for approved combinations in multi-zone buildings. Control, part-load duty, maintenance access and conditional backup are evaluated alongside module count.

- FujiTherma Console Indoor Units
Cassette, ducted, wall-mounted and console units suit different air paths and installation spaces. We choose the capacity, panel and controls together and verify each feature against the actual model.

Is SCA a FujiTherma VRF dealer?
Yes. SCA Engineering supports FujiTherma VRF projects from survey and design through installation and commissioning across Istanbul and the Marmara region.
Should I select A Series or X3?
We compare room loads, simultaneous operation, supply, outdoor space and the piping route. A Series suits compact applications; X3 is evaluated where modular scale and operating-management options are needed.
Does breeze mode supply fresh air?
Breeze mode changes the distribution of room air. Outdoor-air quantity and conditioning are designed separately as part of the ventilation requirement.
