Top Flow VRF
Ceiling concealed units with high-rise discharge, installed above the ceiling so all airflow is horizontal. The usual choice for large open floors.

VRF/VRV Solutions
Variable refrigerant flow systems for buildings that need real zoning, real efficiency and one system instead of many.
A VRF system is not simply a ductless split with a longer pipe. It is a genuinely variable system: outdoor units modulate their output continuously to match the actual load across every connected indoor unit, rather than switching between fixed steps.
For Kochi buildings — offices, clinics, hotels and high-rise floors — that makes VRF the right answer in three situations in particular: when there are many rooms with different usage patterns, when part-load running dominates the year, and when roof space for a row of separate outdoor units is genuinely limited. We design, install, commission and service VRF from Mitsubishi Electric, Daikin and Panasonic platforms.
Indoor unit range
One circuit, many room types
Every indoor unit below runs on the same refrigerant circuit as the outdoor unit.
Modular Side Flow
Side-flow cassettes with modular capacity steps, giving a wider selection of sizes for mixed-occupancy floors.
Side Flow VRF
Slim side-flow indoor units for corridors, small rooms and spaces with a limited ceiling void.
Indoor Concealed Units
Fully ducted indoor units hidden in the false ceiling, with grille outlets as the only visible element.
Water Source VRF
Water-loop heat pump and heat recovery arrangements that recover heat from discharge air and reuse it for reheat or fresh supply.
Indoor Unit Range
Cassettes, ducted, floor standing, ceiling suspended and console indoor units, all on the same refrigerant circuit.
System types
Heat pump, heat recovery or water source
The choice depends on whether the building needs simultaneous heating and cooling, and on what the recovery is used for.
- Heat Pump VRF — Heats and cools on the same circuit. In Kochi's mild winter months a heat pump VRF can supply useful heating at a fraction of the running cost of a separate heater.
- Heat Recovery VRF — Recovers heat from the warmest condenser in the system and reuses it for the coldest rooms. In a building where one side is always warm and the other always cool, this can substantially cut the load.
- Water Source VRF — Uses a water loop as the heat source and sink, which allows heat recovery between simultaneous heating and cooling demand.
If you are not sure which of the three applies to your building, that is exactly what the load calculation is for. We will model it and show you the numbers.
Why VRF
Where VRF genuinely pays back
The benefits that decide whether a VRF system is worth the extra specification effort.
- ('Up to 64 indoor units on one system', 'Branch controller and pipe lengths that let one outdoor unit serve a whole building instead of a stack of separate splits on the roof.')
- ('Genuine part-load efficiency', 'Compressor output varies continuously with demand, so a building at 30% load does not pay for 100% capacity.')
- ('One refrigerant circuit', 'A single two-pipe or three-pipe circuit instead of many individual circuits, which reduces pipework, refrigerant loss and roof clutter.')
- ('Independent zone control', 'Every indoor unit runs on its own controller, so a meeting room can be shut down for the night without affecting the rest of the floor.')
- ('Centralised maintenance', 'Fault codes and status from every unit can be read centrally, so a fault is diagnosed before the occupant reports it.')

FAQ
VRF and VRV questions
The practical questions that come up in every VRF conversation.
Not necessarily, and not over its life. The equipment cost is higher, but a VRF system on a single circuit reduces pipework and outdoor unit count, and the part-load efficiency gain is usually significant on a building that is rarely at full load. We will show you the running cost comparison for your specific building rather than making a general claim.
VRF is the Daikin trade name for variable refrigerant flow. VRV is Mitsubishi Electric's name for the same technology. Different manufacturers use different names, but the underlying principle — continuously variable capacity on a shared refrigerant circuit — is the same.
It depends entirely on the building. A single-floor fit-out with a straightforward pipe route is relatively quick. A live high-rise with phased floor-by-floor working runs across weeks, and we will lay out the programme in the quotation.
Yes, provided the original design allowed for it. We size the outdoor units and branch controllers with a sensible margin, and we document the spare capacity so any future extension is straightforward rather than a redesign.
We do, and we would rather you asked us before anything else is involved. VRF controls and refrigerant circuits need technicians trained on that specific platform; a general repair callout can leave you worse off. Our annual maintenance contract covers fault diagnosis, refrigerant checks, coil cleaning and control system verification.
