Key Features
Commercial Inverter Drive Technology
Engineered to modulate output dynamically across changing occupant and equipment heat loads. The heavy-duty inverter drive regulates motor speed smoothly, avoiding electrical power spikes while maintaining precise setpoint temperatures.
High Air Velocity Air Distribution
Features a high-capacity fan motor and wide louvers that project conditioned air deep across large floor plans, eliminating stagnant air pockets in open-plan offices, retail showrooms, and commercial halls.
Gold Fin™ Anti-Corrosion Condenser Protection
The outdoor heat exchanger is treated with LG’s signature Gold Fin™ surface coating. This anti-corrosion layer shields aluminum fins against salt air, coastal moisture, and atmospheric pollution, extending operational service life.
Extended Installation Piping Flex
Designed to accommodate long refrigerant copper pipe runs and significant elevation differences between indoor head units and outdoor condensers, providing flexibility across multi-storey commercial buildings.
Auto Restart & Fault Self-Diagnostics
Automatically restores previous operational parameters following power interruptions. Integrated diagnostic monitoring codes streamline routine servicing and maintenance troubleshooting for mechanical contractors.
Next-Generation R32 Refrigerant
Operates on single-component R32 refrigerant, offering higher thermodynamic efficiency and superior energy savings while reducing global warming impact by 68% compared to legacy R410A systems.
Ideal Applications
- Large Commercial Offices & Call Centres: Heavy-duty 9.5 kW capacity conditions open office areas (75–90 m²).
- Retail Stores & Showrooms: Maintains consistent indoor climate control despite heavy foot traffic and open doors.
- Server Rooms & Tech Hubs: Continuous inverter cooling handles heavy electrical equipment heat loads reliably.
- Gymnasiums & Event Spaces: High air volume throw distributes conditioned air evenly across open commercial venues.
