AS-18TW4RGSKA00 Specifications, Features & Compatibility Guide
At the core of the AS-18TW4RGSKA00 is a High EER Rotary running on R32 refrigerant, backed by a 100% copper condenser — a hardware combination engineered for sustained peak performance in rooms up to 151-200 sq. ft.. Rated cooling capacity is 5150W, with a BEE 2020 ISEER of 3.65 — placing it in the efficiency-compliant range for 1.5 Ton 3 Star Inverter Split ACs.
Quick Answer
If you need reliable, energy-efficient cooling for a 151-200 sq.ft room in India, the AS-18TW4RGSKA00 1.5 Ton 3 Star Inverter AC is a smart choice. Its BEE 2020 3 Star rating with an ISEER of 3.65 guarantees lower electricity bills over its lifespan. The 100% copper condenser ensures robust performance, making it a sound investment for sustained comfort.
Opt for the AS-18TW4RGSKA00 if your requirement is precise 1.5 Ton, 3 Star cooling for 151-200 sq.ft spaces, prioritizing long-term energy savings from its 3.65 ISEER. Avoid if your room size exceeds this capacity or if initial capital cost outweighs verified energy efficiency in your budget.
✓ Who Should Buy
- •1.5 Ton 3 Star performance suitable for 151-200 sq.ft spaces.
- •Verified efficiency of 3.65 for reduced long-term operational costs.
- •Structural stability for consistent cooling under rigorous use cases.
- •Hardware durability via Copper coil and R32 technology.
- •Built-in grid protection with Stabilizer-free operation voltage management.
✕ Who Should Avoid
- •Spaces or usage requirements exceeding 151-200 sq.ft rated capacity.
- •Installations prioritizing minimum capital expenditure over 3.65 performance.
- •Unstable grid conditions exceeding the functional threshold of Stabilizer-free operation.
- •Environments incompatible with air conditioners physical and thermal dissipation specs.
Product Overview
At the core of the AS-18TW4RGSKA00 is a High EER Rotary running on R32 refrigerant, backed by a 100% copper condenser — a hardware combination engineered for sustained peak performance in rooms up to 151-200 sq. ft.. Rated cooling capacity is 5150W, with a BEE 2020 ISEER of 3.65 — placing it in the efficiency-compliant range for 1.5 Ton 3 Star Inverter Split ACs. Annual energy consumption is 1092.02 kWh under standardised BEE conditions, representing a 20–30% reduction versus non-inverter equivalents. The integrated 190–240V stabilizer-free circuit makes it installation-ready for areas with inconsistent grid supply. Validated for 54°C maximum ambient operation, the AS-18TW4RGSKA00 is built for India's hottest months, with indoor noise held at 44 / 34 dB(A).

Engineering Analysis
Energy performance of the AS-18TW4RGSKA00 is anchored by its BEE 2020 3 Star certification and an ISEER of 3.65. Under standardised BEE test cycles, annual consumption is 1092.02 kWh per year — competitive long-term operational cost over a 5-year ownership horizon. The High EER Rotary employs Variable Frequency Drive (VFD) control, modulating compressor RPM continuously between 15 Hz and 120 Hz to match real-time thermal load — eliminating the energy-intensive stop-start cycles of fixed-speed motors. Peak electrical draw is 1800W at 230V nominal supply, with an inverter drive board maintaining power factor above 0.95 across all load states.
The AS-18TW4RGSKA00 is built around 100% copper condenser coils, which outperform aluminium alternatives with 40% higher corrosion resistance — a critical durability metric for India's coastal zones, humid interiors, and regions with salt-laden particulate air. Copper's superior thermal conductivity (401 W/m·K vs aluminium's 205 W/m·K) means heat rejection is faster and more complete, directly preserving the rated ISEER across the product lifespan. R32 refrigerant carries a Global Warming Potential of 675 — 68% lower than R410A (GWP 2088) — requiring 30% less charge by weight, reducing both refrigerant leak risk and total lifecycle environmental load. Multi-stage filtration (PM 2.5, Anti-bacterial, Dust, HEPA) captures PM2.5 particulates, volatile organic compounds, and microbial contaminants — delivering measurably healthier indoor air beyond raw temperature control. 2-Way motorised air distribution directs conditioned air uniformly across the room throw envelope, eliminating thermal stratification and hot-spot buildup. The 10 Years compressor warranty signals the manufacturer's projected confidence in mechanical durability under India's sustained 10–12 hour daily summer load patterns.
Stabilizer-free operation (190–240V) eliminates the need for external voltage hardware. Auto-restart with non-volatile memory ensures the AS-18TW4RGSKA00 resumes at the last-set temperature and mode after power interruption — a functional reliability requirement for Indian grid zones experiencing 4–10 daily outages during peak summer months. Integrated Wi-Fi and app-based control enables schedule automation, real-time unit-level energy monitoring, and geofencing-based pre-cooling to minimise idle runtime and reduce consumption by up to 15%. The onboard diagnostic module performs 12 system integrity checks at every startup — refrigerant pressure levels, coil surface temperature, compressor current draw, fan motor RPM, and PCB supply voltage — flagging anomalies before they escalate into compressor failure events. Validated for 54°C maximum ambient operation — 7–9°C above the IEC 60335-2-40 standard test baseline of 43°C — the hardware thermal management stack is certified for India's harshest summer regions including Rajasthan, Vidarbha, coastal Andhra Pradesh, and the Gangetic plains.
