Sanyo RCS-KR1EG: Efficient Temperature Control Solutions

GU Type Heat Exchanger CFR Units

SANYO’s new heat recovery ventilation system allows total control via a system network whilst modulating the temperature and humidity of incoming air supply.

•Integration of heat recovery ventilation and DX coil technology for optimum air temperature control

•The DX coil can be connected to all ECO & GHP outdoor units

•Easy to clean filter

•Compact design

•Filter option

•3 Way: Solenoid valve kit is required for each unit

•2 Way: RAP kit is required for each unit

The values in ( ) for the external static pressure and operating sound are for use of booster cable. *1: Heat recovery capacity by heat exchanger. Data subject to change without notice.

The CFR-PHE unit structure is constructed from Aluzink frame work and galvanised steel with 20 mm thick fire resistant acoustic insulation, reducing both weight and sound levels to a minimum. The system is supplied with ducted spigots which can be positioned either at the front or side of the unit to ease installation.

•High efficiency heat exchanger

•Easy to clean filters

The high efficiency low pressure loss total heat exchanger is made of specially treated paper to enable the unit to be as efficient as 76% during normal operation. This allows system to recover both latent and sensible heat.
