There is a stretch of late May and June in Delhi when the loo blows all afternoon, the terrace slab is too hot to stand on, and the colony's older ACs start blowing lukewarm air by four o'clock. That is the moment an air conditioner's high-ambient rating stops being a line on a spec sheet and becomes the entire point of owning one. The Toushi Plus RAS.E318PCDIBT is built for high ambient cooling up to 52°C — Tropical Design construction intended for sustained running in exactly these conditions, not adapted from a milder climate. Behind it sits 5100 W of maximum cooling output for rapid pull-down, so a top-floor bedroom that has been baking since noon comes down fast and then stays there. The worst week of the year is precisely when the difference shows.
Xpandable+ — an inverter that flexes with the heat load and the grid
A fixed-capacity air conditioner is either working too hard or barely working for most of the day. Xpandable+ inverter technology reads the actual heat load in the room and expands or eases the compressor's output to match it — full effort for a west-facing living room at three in the afternoon with the whole family in it, a gentle fraction of that for one person asleep at two in the morning. Because the compressor modulates instead of slamming on and off, the room temperature holds steady rather than swinging a couple of degrees either side of the setting, the electricity draw settles low once the room is cold, and the compressor itself lives a longer life for having been spared thousands of hard starts. Just as importantly for Delhi, Xpandable+ helps the unit hold its cooling performance through the voltage instability that arrives every summer afternoon when the entire grid is straining at once — and Powerful Mode is there when you want an immediate burst of maximum cooling on demand.
100% inner-grooved copper, SuperSlit fins, anti-corrosive coating — built to survive Delhi
Every part of the refrigerant path here is copper: 100% inner-grooved copper tubes and a copper condenser coil. The grooves running along the inside of the tube wall increase the surface area the refrigerant touches, so heat leaves the room faster than a smooth-bore tube manages, and copper itself both transfers heat better and resists corrosion far longer than aluminium. SuperSlit fins squeeze more heat exchange out of the same coil area, and an anti-corrosive coating protects the whole assembly from the specific cocktail this city serves up — industrial pollution, monsoon humidity, construction dust, and the winter smog that settles on everything. That coating is the specification that decides whether an AC is still cooling strongly in its eighth summer. On the electrical side the unit runs stabilizer-free, so there is no extra box on the wall and no extra point of failure between the socket and the machine.

🛠️ Everything on the remote
The LCD backlit remote is a small thing that matters at 2 AM — you can read the setting and change it without turning on a light. And the Filter Clean Indicator tells you when the mesh genuinely needs washing, which is what keeps both the airflow and the electricity bill where they should be through a dusty summer and a high-AQI winter.
A finer mesh than a standard filter, trapping dust, pollen, allergens and bacteria before they reach the room. Hydrophilic coated fins shed the moisture that would otherwise let bacteria breed inside the unit. In a city where the AQI decides whether you open a window, this filter is doing real work for most of the year.
The inverter rotary compressor varies its speed rather than cycling hard, settling into a low steady draw once the room is cold. An ISEER of 4.30 turns that into real savings across a Delhi cooling season that runs March to October, and ECO Mode lets you cap consumption deliberately on the long days.
Activate the warranty for ₹299 plus taxes and Hitachi adds two extra maintenance visits in the first year — one wet service and one dry — plus priority technical support, extended service hours until 8 PM, and gas charging at no extra cost for compressor or coil related work. Coverage runs across the functional components including the PCB, the indoor and outdoor unit coils, and the compressor.
Hitachi indoor unit, Hitachi outdoor unit, LCD backlit remote control, installation kit, user manual and warranty card — everything needed for our team to guide a clean installation the day it arrives.
