Domestic Heating systems are air-to-water heat pumps available as either a Yutaki monobloc (Yutaki M) or Yutaki split system type(Yutaki S & Yutampo).

Air source heat pumps provide an economical and environmentally friendly alternative to traditional heating systems. By taking advantage of thermodynamics processes, heat pumps provide more heat output then the energy input.

Hitachi Yutaki M range for instance, has a full load COP of up to 4.31, where 1kW of electrical energy is used to provide up to 4.31kW of heating output.

Hitachi offers a wide variety of control systems giving customers the flexibility to control their air conditioning system to suit their requirements.

The H-Link communications system, which is common across all System Free Utopia and Set Free products, provides a single and comprehensive range of local, central and BMS gateway controller options.

Even RAC products benefit, with a H-Link interface module now available.

Utopia are high specification single and multi split systems. This range includes the compact ES, IVX Comfort & IVX Premium and the RASC centrifugal ducted types.

The unique IVX systems incorporate VRF (Variable Refrigerant Flow) control on up to 8 indoor units, making them the market leader in terms of flexibility, user comfort and energy efficiency.

The RASC centrifugal ducted units are outdoor units specifically designed to be installed internally, to allow an invisible air conditioning installation.

All Utopia systems are compatible with System Free indoor units, with 12 indoor unit types and 15 capacities available.

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.

Samurai Chillers offer world-renowned reliability thanks to Hitachi's own twin screw compressors.

Samurai are commercial and industrial chilled water systems, including cooling only and heat pump air-to-water, water-to-water and condenserless types.

The Samurai are based upon Hitachi's peerless twin screw compressors, which are industry renowned for their efficiency and reliability. A slide valve provides continuous capacity control from 15 - 100% at high part load efficiency, while maintaining impeccable low vibration, low noise levels and a high power factor.

Samurai chillers include many high specification features as standard, such as acrylic coated condenser coils and star delta compressor motors.

Accurate +/-0.5??C water leaving temperature control is possible, with water leaving temperature controlled from -10??C to 15??C on cooling capacities from 106 kW to 1280 kW.
