INA312K50 Specifications, Features & Compatibility Guide
The INA312K50 delivers powerful cooling for Indian homes up to 90 sq. ft. using a robust 3.77 ISEER rating. Its 100% copper condenser ensures reliable performance even during extreme 52°C summer heatwaves.
Quick Answer
Investing in the INA312K50 is a smart move if you need precise temperature control for a 90 sq ft room without high electricity costs. Its Rotary compressor with Variable Frequency Drive ensures silent, stable operation during intense Indian summers, making this 3-star inverter unit a reliable asset.
Choose the INA312K50 for efficient cooling in compact dens or offices up to 90 sq ft; avoid it if your space exceeds this capacity, as the 3500W output is strictly tuned for small, energy-conscious Indian homes.
✓ Who Should Buy
- •1 Ton 3 Star performance suitable for Up to 90 sq ft spaces.
- •Verified efficiency of 3.77 for reduced long-term operational costs.
- •Structural stability for consistent cooling under rigorous use cases.
- •Hardware durability via Copper coil and R410A technology.
- •Built-in grid protection with Standard power cycle voltage management.
✕ Who Should Avoid
- •Spaces or usage requirements exceeding Up to 90 sq ft rated capacity.
- •Installations prioritizing minimum capital expenditure over 3.77 performance.
- •Unstable grid conditions exceeding the functional threshold of Standard power cycle.
- •Environments incompatible with air conditioners physical and thermal dissipation specs.
Product Overview
The INA312K50 is a field-ready 1 Ton 3 Star Inverter Split air conditioner designed for reliable operation on standard Indian single-phase circuits. Its BEE 2018 3 Star certification and ISEER of 3.77 translate to 100 kWh annual consumption — a premium efficiency outcome for rooms Up to 90 sq. ft.. Cooling capacity is rated at 3500W, delivered through a Rotary alongside a 100% copper condenser and R410A refrigerant system. At 43 dB(A) indoor, it remains acoustically suitable for bedrooms and quiet spaces. Certified for up to 52°C ambient operation, it covers the thermal range of every major Indian climatic zone.

Engineering Analysis
Energy performance of the INA312K50 is anchored by its BEE 2018 3 Star certification and an ISEER of 3.77. Under standardised BEE test cycles, annual consumption is 100 kWh per year — competitive long-term operational cost over a 5-year ownership horizon. The 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.
The INA312K50 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. R410A refrigerant carries a Global Warming Potential of within BEE and Montreal Protocol approved thresholds for the Indian market. Multi-stage filtration (Dust, Anti-bacterial) 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 5 Years compressor warranty signals the manufacturer's projected confidence in mechanical durability under India's sustained 10–12 hour daily summer load patterns.
Standard power management rated at 220 - 240V ensures safe operation. Auto-restart with non-volatile memory ensures the INA312K50 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. Validated for 52°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.
