–VRF Indoor units
– Discover the wide portfolio of our VRF Indoor Units
– The inventor of the 4-way cassette and still the innovation leader
– SmoothDrive – more stable and accurate temperatures, improved energy efficiency
– Maximize your comfort with Hitachi's VRF Indoor Units
- Prevent cold drafts
When starting up air conditioners can discharge very cold air to quickly reach the required temperature for the room, but this can result in cold drafts making occupants uncomfortable. With GentleCool you can adjust the balance between achieving a lower room temperature quickly and avoiding cold drafts.
- Occupancy sensing technology
With CrowdSense(2) technology, select units can determine how many people are in a space and adjust the cooling or heating capacity accordingly, so the room will never get too hot or cold, whether it’s crowded or almost empty
– Improve air quality with low-cost upgrades
