The Akabishi RAM-SE18VG / RBM-SE18VG is a 1.5 Ton, 3-Star fixed-speed split air conditioner from Mitsubishi Electric India / its Akabishi brand. Built for medium to larger rooms, this AC gives solid cooling performance with simplified technology (non-inverter) and a focus on durability and cost-effectiveness.

• Cooling Capacity & Performance
  With 1.5 Ton capacity, this model delivers about 5,100-5,050 W of cooling power under rated conditions. It’s capable of handling warm to hot weather conditions well, especially when full cooling is required. Because it is fixed-speed, it runs at full capacity when switched on, then cycles off once target temperature is reached. The cooling swing is therefore larger than inverter models, but the system is simpler.

• Energy & Efficiency
  It carries a 3-Star BEE rating, which means moderate energy efficiency. It’s more efficient than 2-Star fixed-speed models, but will consume more power compared to inverter or 4/5-Star units under light load. The ISEER is about 3.52.

• Power / Electrical Specs
  • Rated Current: ≈ 5.91 A under normal operation in this model. 
  • Input Power (W): ~ 1,450 W for this model. 
  • Voltage Supply: 230 V, 50 Hz, single phase.

• Noise & Airflow
  • Indoor air flow (Turbo / High / Mid / Low) ~ 1,080 / 950 / 840 / 790 CMH depending on speed. 
  • Indoor noise levels are in the ~ 43-49 dB range depending on speed. Turbulent or high-fan modes are louder. 
  • Outdoor unit noise is around 60 dB(A).

• Refrigerant & Coil
  Uses R-32 gas, which is better for the environment (lower global warming potential) and efficient in terms of heat exchange. Condenser coil is 100% copper which helps in durability, better heat transfer and easier servicing.

• Build, Ambient & Other Features
  • Designed to function in ambient conditions up to ~ 48°C (outdoor temperature) without severe drop in performance.
  • “Blue Fin” coating on fins to resist corrosion, typical dust / moisture resilience features. 
  • Fast Cooling mode, PM2.5 filters in some listings, auto-restart after power cuts, LCD-backlight remote etc.

• Dimensions & Installation
  • Indoor unit dimensions ~ 800 × 230 × 295 mm (W × D × H) for the 1.5 TR SE-series. 
  • Outdoor unit size ~ 781 × 241 × 557 mm and weight accordingly. 
  • Pipe connections: Liquid / gas pipe diameters ~ 6.35 mm / 12.7 mm in many similar SE-models. Maximum pipe length ~ 15 m, max height difference ~ 10 m in typical installations.
