ECO G 3 Way Outdoor Unit Specifications
ECO G 3 Way Heat Recovery VRF System
LPG option
The option of using LPG as a power supply increases flexibility
and avoids the problems of potential site restrictions in the
future. The purer fuel is also excellent for further reductions
in CO
2
emissions - a fact recognised by the government.
Still the only heat recovery (3 way) GHP system in
Europe.
The new M Series ECO G 3 Way offers even more
performance and outstanding features when you need
simultaneous heating and cooling. Now with increased
capacities available from 16HP to 25HP, SANYO offers the
greatest choice and flexibility to solve any power problem or
site requirement.
• Simultaneous heating and cooling for total control
• Reduced gas consumption by Miller-cycle engine
• Reduced electrical power consumption by using DC motors
• New lightweight design by use of aluminium engine block
reduces weight by 110kg
• Part load efficiencies increased
• Connectability increased to up to 36 indoor units
• Now available in 16, 20 and 25HP
• 200m maximum allowable piping length (L1) (equivalent - refer
to technical manual)
• Diversity ratio 50% - 130%
• Extended pipe runs (total 500m)
• Silent mode offers a further 2dB(A) reduction
• 10,000 run hours between engine service intervals (equivalent
to one maintenance every 3.2 years*)
• Full heating capacity down to -20°C
• No defrost cycle
* Assuming 3120 running hrs per year - 12 hrs x 5 days x 52 weeks
ECO G 3 Way is ideal for the following types of
application:
• Office buildings with a diverse range of room temperatures
due to differing load profiles.
• Buildings with computer rooms requiring year round cooling.
Additional parts
By taking its power supply from the nearest indoor unit, the
SANYO solenoid valve (change-over box) does not require any
additional fused spur and at only 150mm high can be easily
installed within a 200mm void space.
