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
• Connects to all ECO & GHP outdoor units with a filter option
• 3 Way: Solenoid valve kit is required for each unit
• 2 Way: RAP kit is required for each unit

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
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.

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.

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 engine waste heat, which is normally exhausted into
the atmosphere, is recovered via the heat exchanger and
effectively used as hot water, so the GHP system acts as a
subsystem that alleviates the load on the client’s main hot
water system and therefore offers “free” hot water. Water heating capacity up to 65 kW (of 75°C hot water)
