FEATURES AND BENEFITS OF MONOZONE (RAC) & MULTIZONE (RAM) OUTDOOR UNITS
Monozone/Multizone All DC PAM Inverter Multi
Air Conditioners with Twin Rotary and Scroll
Compressors
HITACHI proudly introduces the new line up of Monozone/Multizone series in order to respond to the request of air conditioning markets, for small and medium capacity units.
A new one-room type “MONOZONE” is added to the “MULTIZONE” series in which up four indoor units can be connected to one outdoor unit. Thus, small offices, hotels, shops or houses can be air-conditioned properly by using combinations of the one-room type to four-room types of indoor and outdoor units. What’s more, the on-board PAM provides high power and performance for greater energy efficiency. Creating the optimum, comfortable air-conditioned environment is Hitachi’s specialty.

High economical efficiency operation
HITACHI uses the high technology to achieve the high operation efficiency. The applications of the following technologies provide HITACHI to achieve results like the great power saving due to heat recovery system.
These technologies are:
All PAM Inverter
Inverter driven systems have a big performance advantage over constant speed systems. The variable compressor can make a very fast start-up and reach the setting temperature rapidly, then reduce the rotation speed to achieve energy savings of about 30% with no loss of comfort. Moreover, only Hitachi’s DC driven fans and compressors deliver about 10% better performance than AC inverters. HITACHI is the world’s pioneer of DC inverter systems and PAM in room air conditioners.
Inverter Control
Hitachi’s PAM control system is able to keep the current pulse waveform to avoid distortion. It enhances the power efficiency. The cutting edge device is employed in HITACHI MONOZONE/MULTIZONE for your comfort and energy saving for our environment.
Rapid start up The variable speed compressor (inverter) enables the system to rapidly reach the desired room temperuature setting.
Once the desired room themperature has been achieved, the compressor rotation speed is reduced, saving up to 30% in energy usage (when compared to conventional systems) without compromising comfort levels
High performance, heating at –15°C
H
ITACHI’s PAM inverter system achieves the effective utilization of power input and minimizes loss less than 1. You can enjoy high COP, top class in industry. Especially heating performance is improved and you can enjoy heating comfort even at -15°C degree ambient temperature
Auto-Restart
If auto-restart mode was selected at the ON/OFF switch, the unit automatically resumes operation in the mode that was in use beforehand.
* When timer is set, Auto Restart feature to previous mode is not available
Auto Changeover (for RAC-25/35/50/65NH5)
The built-in microcomputer continuously selects the best operating mode automatically to provide maximum comfort, based on the set temperature and measurements taken every 10 minutes by a sensor.

Digital DC scroll compressor (for RAM-80QH5)
The motor uses digital control to maximize PAM control performance
Loss during high-speed revolution is reduced, thanks to digital control of the motor.
Three balancers mounted on the crankshaft lessen shaft run out during high-speed revolution.
Efficient operation with drastically reduced refrigerant leakage is ensured by the automatic compression system, in which that tip of the slewing scroll is kept in absolute contact with the fixed scroll, in addition to special processing of the scroll surface.
Twin rotary compressor (for
RAM-40/55/65/72/90/130QH5 and
RAC-25/35/50/65NH5)
Hitachi’s new twin rotary compressor has less vibration and higher efficiency than conventional rotary
compressors
Two rotating cylinders ensure well-balanced rotations unlike the conventional single rotary type, thus vibration noise is greatly reduced.
The compressor’s operation is improved by moving two independent cylinders efficiently
Comparison of Vibration
Use of the HFC new R410A Refrigerant
HITACHI developed and introduced all models to meet the global needs to help protect the Earth’s environment by using non-ozone depleting refrigerant, R410A as Hitachi’s standard series.
Easy installation (for RAM-90QH5)
The 5-room model covers up to 75m length with vertical interval of up to 20m.
Easy servicing
Self-diagnosis
Errors are easily identified by the LED blinking patterns of the indoor and outdoor units.

Nano Titanium Filter (RAF-FX8)
Nano Titanium, a nanoparticle antimicrobial agent. Titanium Oxide (TiO2) has been used as photocatalyst, and is a technology for deodorization and anti-bacterial measures, which has been recently put to practical use. The catalyst has been reduced to the “nano” level using Japanese original technology, to produce a no-light catalyst, thereby improving its effect. This cutting-edge Nano Titanium technology, which Hitachi is the first company to install for home appliances, works on the scale of the nanometer (1/1,000,000mm) to catch the tiniest bacteria and odor-causing molecules. Hitachi will optimize and apply this state-of-the-art technology to its main products.
Higher performance
A lambda shaped design provides a larger and wider area for heat echangef thus ensuring high performance.

Comfortable coolng and heating
• Air Flow Control System (lower blowing type)
During heating mode, the warm air is directed to stay well controlled at floor level. Whereas during the cooling mode, cool air is distributed to the whole room to prevent direct cold blast onto the person body.

[RAF-25FX8(W) or (B), RAF-35FX8(W) or (B),
RAF-50FX8(W) or (B)]
With dynamic extended airflow, the airflow could reach further to the corners of the room. Your room can be efficiently warmed or cooled with conveniently simple push of button on the remote control.
Digital DC scroll compressor (for RAC-FX8)
The motor uses digital control to maximize PAM control performance
Loss during high-speed revolution is reduced, thanks to digital control of the motor.
Three balancers mounted on the crankshaft lessen shaft run out during high-speed revolution.
Efficient operation with drastically reduced refrigerant leakage is ensured by the automatic compression system, in which that tip of the slewing scroll is kept in absolute contact with the fixed scroll, in addition to special processing of the scroll surface.

Built-in drain pump
This air conditioner is equipped with an internal drain pump to remove accumulated condensed water from the drain pan even while it is operating. A float switch monitors the water level and automatically activates the pump as necessary.
Twin rotary compressor (for
RAC-50/60/70DH7)
Hitachi’s new twin rotary compressor has less vibration and higher efficiency than conventional rotary compressors
Two rotating cylinders ensure well-balanced rotations unlike the conventional single rotary type, thus vibration noise is greatly reduced.
The compressor’s operation is improved by moving two independent cylinders efficiently
