CIAT Ozonair Ltd - Products and Company Details

First for CIAT Ozonair

CIAT Ozonair says it is the first manufacturer to market air/water inverter heat pumps. The Aquaciat Grand Inverter range, is the result of close collaboration with US firm DCC Danfoss. The Aquaciat Grand Inverter range is equipped with Danfoss Inc's Apexx VSH Series variable speed scroll compressor, designed for R-410A heat pumps. The Apexx VSH Series optimises energy efficiency by adapting proportionally to the real needs, limiting waste energy and achieving savings of 20 per cent. Suitable for heating and air conditioning of offices and hotel buildings, the range comprises of three models.

Designed to help achieve comfortable hospitals

The new CIAT OZONAIR Coadis Medical Comfort is the first comfort unit on the market that has been specifically designed for hospital rooms, with an inbuilt air purifier, claims the company. The unit meets challenging NHS air quality demands, whilst providing thermal and acoustic comfort. The Coadis Medical Comfort incorporates an all-in-one diffusion system allowing installation in suspended ceilings of hospital rooms, saving floor space. CIAT's Purify function avoids the harmful effects of PM2.5 particulates, in three ways: use of a filter (reduces particles by 90 per cent in 30 minutes), air inlet protection avoiding the intake of bacteria, and thorough uniformed diffusion of air in the room. In addition, a 'condensation-free' function has been incorporated to avoid the potential risks of bacteria proliferation due to water retention in the drain pan. The unit also features high energy efficiency fans and V3000 electronic control.

A special defence recipe

Designed for simple and quick access for maintenance, Ciat Ozonair's Air Access air handling units have been installed at a new kitchen for the MoD in Hampshire. A total of 17 CIAT units were installed to provide general supply and extract ventilation. Each AHU is fitted with a plate heat exchanger to recover heat extracted from the kitchens by means of conventional kitchen extract hoods. The design of the system allows all mechanical and electrical services to be run adjacent to or in the built-in Multi Service Bulkhead allowing complete access to the side of the unit. This obviates the possibility of the AHUs becoming contaminated with grease from the extraction system. Each AHU handles an air volume of 3.0 m3/s on both supply and extraction, and is capable of recovering 55 kw of heat from the kitchen.

Giant green ground source system for hospital

The largest ground source system in Europe, at the Churchill Hospital in Oxford, features Ground Source Heat Pumps from CIAT Ozonair. The hospital complex, constructed recently by a joint venture of Alfred McAlpine and Impreglio, comprises a cancer centre, surgery and diagnostics building, and private patients unit. The Oxford Radcliffe Hospitals NHS Trust specified that the facilities should be 'exemplars of energy-efficient, low carbon hospital design'. The 35-mile long ground source heat pump system uses water to collect and return heat some metres below the surface. The heat is then transformed through eight of CIAT Ozonair's heat pumps to provide more than 2.5 mW of heating and cooling, with scope for a ninth. The system uses 240 bore holes, each 100 m deep. Every kilowatt used to power the system should generate up to 6 kW, says engineer Haden Young.

Inverter technology

Ciat Ozonair Ltd has extended its range of air-source energy heat pumps with the introduction of the Aqualis Inverter, employing the latest DC Inverter technology. Designed as a back up boiler for the residential market, in either new or renovated housing. Aqualis Inverter combines efficient performance with quiet operation and elegant design. Suitable for outside insulation, it can operate in external temperatures as low as -20 degrees centigrade. A further feature of the latest generation DC Inverter compressor technology is its capacity to constantly adjust to the needs of the house, helping to maintain efficiency. Aqualis Inverter provides hot water up to a temperature of 55 degrees centigrade, ideal for low temperature radiators and underfloor heating. The system can also be used as back up to an existing boiler, or as a method of cooling for use in the summer months.

Ecociat heat recovery unit

CIAT Ozonair's first heat recovery unit - the Ecociat - has the potential to reduce domestic hot water bills by up to 70 per cent. The unit captures and recycles heat contained in air brought in and drawn out by natural ventilation systems. Instead of being vented outdoors, this energy is used by Ecociat to heat domestic hot water. The unit is designed for use with conventional boilers and other systems run on fossil fuels and is simple to install without changes to existing circuits. Compact and silent, it offers all year round energy efficiency with a COP of 3.5. Installed on the roof or in a plant room of hotels, offices, healthcare establishments and retirement homes, Ecociat can be adapted simply and quickly to any existing building or integrated into buildings under construction. Connected to the natural ventilation system, it handles between 3,000 m� and 5,500 m� of air per hour.
