Nagakawa Inverter 2 HP NIT-C18R2U35 ceiling cassette air conditioner

The Nagakawa NIT-C18R2U35 is a 2 HP Inverter ceiling cassette air conditioner equipped with the Auto Clean and Inside Cleaning feature pair, keeping the indoor unit cleaner even after long-term use.

Dual indoor unit cleaning system

Nagakawa integrates both Inside Cleaning and Auto Clean to remove moisture and dust buildup inside the indoor unit after each run. This is the part that easily accumulates moisture and dirt with prolonged use, especially in places where the unit runs continuously such as offices, retail areas or large living spaces.

Inside Cleaning focuses on deep cleaning the inside of the indoor unit, at the spots where dust and moisture tend to collect. Auto Clean dries the indoor unit right after you turn the unit off, limiting prolonged dampness. Working together, the two features make the airflow more pleasant and also reduce the need for regular manual cleaning.

Neat ceiling cassette design

Indoor unit

The NIT-C18R2U35 is a ceiling cassette type: the whole body sits concealed above the ceiling, and from below only a tidy panel is visible. This installation style suits meeting rooms, offices, showrooms and any place that wants to keep the ceiling open and seamless.

The square panel has evenly arranged air outlets. The neutral color helps the unit blend into many kinds of spaces without spoiling the look. The indoor unit also has a temperature display so you can easily monitor it while in use.

Outdoor unit

On the outdoor unit, Nagakawa uses copper refrigerant pipes and BlueFin-coated aluminum fins. This combination increases durability and gives the unit better corrosion resistance when installed in damp or dusty locations.

The unit runs on R-32 gas, meeting the need for stable cooling in medium-sized spaces. For a ceiling cassette model installed for long-term use, durable heat-dissipating fins are a factor well worth valuing.

18,000 BTU capacity, Strong mode

The unit has a capacity of 2 HP - 18,000 BTU, suitable for an area of 20 - 30m² (volume of 60 to 80m³). This capacity is a good fit for small offices, medium-sized meeting rooms or commercial areas that need strong, even cooling.

When you need to cool down quickly, simply turn on Strong mode so the unit speeds up cooling and brings the room temperature to the set level sooner. In spaces that are often crowded or prone to stuffy heat, this mode makes everyone feel noticeably cooler from the first few minutes.

Auto swing, balanced cooling

The louver swings up and down automatically, spreading cool air throughout the room instead of concentrating it in one fixed corner.

In a room of 20 - 30m², this mechanism makes the coolness more even across different positions, avoiding the situation where it is freezing near the unit while places farther away never seem to cool down.

Inverter saves energy during long hours of use

Nagakawa equips this model with Inverter technology, so the output always closely follows the cooling demand. Once the room is as cool as you want, the unit switches to maintaining a steady cooling level instead of turning off and on repeatedly.

Thanks to this operation, the room temperature is more stable and the unit also saves energy when it has to run for many hours in a row. According to the specifications, the unit consumes about 1.6 kWh, a reasonable level for a 2 HP ceiling cassette air conditioner.

Coarse dust filter

The unit uses a coarse dust filter, which blocks large dust particles before the air is blown into the room.

When installed in an office or enclosed room, this filter layer makes the air more pleasant at a basic level and reduces the amount of dust throughout the time the unit is running.

Convenient operating features

Besides cooling, the NIT-C18R2U35 also has several other practical features:

• Sleep Mode adjusts the temperature for greater comfort when the unit runs at night.
• Dehumidifying is very useful on humid days or when the air is damp.
• Self-diagnosis helps you quickly notice when the unit shows signs of abnormality.
• On/off timer lets you control the running schedule.
• Auto restart after a power outage, the unit resumes running with the previous settings.

The Nagakawa Inverter 2 HP NIT-C18R2U35 is a suitable choice for offices, meeting rooms or spaces of 20 - 30m² that want a neat ceiling cassette unit with fast cooling and stable operation. It is especially suited to those who value the energy savings of Inverter, Strong mode, and the Inside Cleaning - Auto Clean feature pair that keeps the indoor unit clean and the airflow always pleasant.
