Delivering Air Conditioning Excellence

Ventilation

Thanks to KPI energy recovery, Hitachi’s ventilation system uses celluloid heat exchange to transfer temperature and humidity – perfect in environments where stable humidity is essential. Hitachi’s ventilation systems offer airflows varying from 250 to 2,000 m3/h. Better still; its low noise level means the whole office can concentrate without a rattling, background sound distracting them from their work. With the high percentage energy recovery rate of 78%, it provides an exceptional fresh air supply to any indoor environment. The systems simple design means no more fiddly maintenance job – granting direct access to all the systems components.

KPI-Energy

Ventilation is a range of products well known for being the lowest height on the market (capacity of 2000m3/h from a unit that’s less than 650mm high). This includes the KPI-Energy recovery using Celluloid heat exchanger to transfer temperature and humidity, the KPI-Heat recovery using aluminium to transfer temperature only. By using KPI-active, you are able to reduce your heating/cooling loads when used in conjunction with VRF or Split systems. The Econofresh kit is easy to install, it provide up to 100% fresh air and has the ability to provide ‘free cooling’ when the outdoor temperature is below the indoor setting temperature. KPI Energy recovery uses Celluloid heat exchanger to transfer temperature and humidity. This product is suitable for environments where the air contained an important amount of humidity. The airflows vary from 250 to 2,000 m3/h. This product is suitable for offices areas due to low noise levels. This product has a high efficient exchanger which incorporates fresh air supply for indoor environments, an energy recovery up to 78%. As a result, the cooling/heating load can be reduced by up to 20%. All the products have an easy maintenance due to simple, efficient design which gives a direct access to the products components. Option such as Hard wired remote controller which will control the system for up to 7 days are available. Finally, these products can be associated “H-Link II Control” and “CS Net Web”.

KPI Active

By using KPI-active, you are able to reduce your heating/cooling loads when used in conjunction with VRF or Split systems. KPI Active Energy recovery uses Celluloid heat exchanger associated to a DX refrigerant section to transfer temperature and humidity. The airflows vary from 500 to 1,000 m3/h. This product is suitable for offices areas due to low noise levels. This product has a high efficient exchanger which incorporates fresh air supply for indoor environments, an energy recovery up to 78%. As a result, the cooling/heating load can be reduced by up to 20%. All the products have an easy maintenance due to simple, efficient design which gives a direct access to the products components. Option such as Hard wired remote controller which will control the system for up to 7 days are available.Finally, these products can be associated “HLink II Control”and “CSet Web”

Econofresh

The Econofresh kit is an intelligent accessory device that is easy to install. The Econofresh kit can provide up to 100% fresh air and has the ability to provide “free cooling” when the outdoor temperature is below the indoor setting temperature. This kit in conjunction with the RPI In the Ceiling system will not only maintain the correct room temperature and provide fresh air, but also natural cooling therefore increasing energy savings.

  • Fresh air cooling during intermediate seasons saves energy. This unit uses an economiser for cooling, which takes in fresh air if the outdoor temperature is cooler than the indoor air. No compressor is used and thus a remarkable amount of energy is saved
  • A fresh air intake system keeps the air in a room clean at all times. The optional CO2 sensor can sense the degree of pollution of the air in the room and automatically control the fresh air flow
  • Utilising the free cooling potential of the UK climate, the combination of the Econofresh and the RPI 5.0FSN3E can reduce the power input required by more than 20% when compared to a standard RPI 5.0FSN3E system
  • Hard wired remote controller with built in 7 day timer (as per RPI-FSN4E In the Ceiling unit)
  • Optional simplified hard wired or infra red remote controller with 24hr timer
  • Compatible with H-LINK II Control and CS Net Web controls that integrate with all leading BMS protocols.
