The SANYO ECO G Water Heat Exchanger can provide water at a wide range of temperatures suitable for a variety of commercial applications ranging from comfort air conditioning to food processing or the replacement of boilers and other systems.

•New 25 kW and 50 kW capacity models

•In cooling (chiller) mode provides water from -15°C to 15°C

•In heating mode can provide hot water up to 55°C, for example for under floor heating applications

•Includes water flow protection to prevent freezing

•Temperature sensor included

•S-Link communication is connectable with any controllers

•Split system means reduced installation cost and the use of a less powerful circulation pump

•One touch changeover between cooling and heating operation

•The system can accommodate up to 120m (actual length) of piping between the outdoor unit and the water heat exchanger, allowing flexibility of installation location

•The system uses antifreeze coolant, so it can produce cold water even at -15°C, thereby complying with “brine specifications”

The CFR- PHE uses a unique purifying Bioxigen system to produce negative ions this can reduce pollutants by up to 85% whilst improving, significantly air quality within most environments.

• High efficiency heat exchanger & Easy to clean filters

The CFR-PHE unit structure is constructed from Aluzink frame
