– Small-scale type [Koala]
Energy efficiency and downsizing achieved with the most advanced replacement products！
The New Koala has improved its efficiency. (Koala CXR series)
105~352kW (30~100USRT) [Gas · Oil-fired]
The New Koala has improved its efficiency. (Koala CXR series)
105~352kW (30~100USRT) [Gas · Oil-fired]
– The CXR series offers energy efficiency and compactness.
Recommended as replacement products because of high efficiency with a COP=1.23*1) and greater compactness
High efficiency contributed to 14% reduction in fuel consumption (cooling mode)
※ 1: LHV basis/ catalogue standard specification/ cooling mode
※ 2 [Comparison models] HAU-FG-100SA (Previous mode : 1986-1996)/HAU-G100V (Previous mode : 1996-2000)/ HAU-F100CXR High efficiency contributed to 14% reduction in fuel consumption (cooling mode)
Installation footprint of the heat source unit reduced by 13%*3 by downsizing; recommendable as replacement products.
※ 3 : This is a comparison with the previous model (V series: 1996 – 2000) for a 100 USRT model. Comparison of the installation footprint is based on the main unit base dimensions, and it does not include the flue gas duct and chimney areas. In terms of the overall series, it is some 3% to 14% reduced. (except 30CXR)

– Achieved low height of 1900mm including indoor cover
Overall height of 1,900 mm including indoor cover realized (indoor models: 30 to 80 USRT)
Installation possible on an existing foundation (foundation of conventional model S series Koala*4)

– Easy maintenance
Removable cooling water chamber box (for cooling water system)
Flange-type covers employed for the cooling water chamber box: maintenance simplified.

– Improvements in ease of installation
Making installation of the equipment much easier The height dimension of all the models has been kept under 1,900 mm (with the covers removed) for easing the equipment carry-in into the machine room.
Consistency of chilled/hot water, cooling water and fuel pipe connection direction.
The chilled/hot water pipes, cooling water pipes and fuel pipes connection are all positioned on the rear side while the pipe height positions are all uniformed for models from 40 to 100 RT. This has facilitated the piping design and installation when installing a multiple number of units.

Maximum working pressure of chilled/hot water increased
To accommodate with high-rise buildings, the maximum working pressure of the chilled/hot water system has been raised to 780 kPa (8 kg/cm²G).
[Maximum working pressure for cooling water is 490kPa(5 kg/cm²G)]
