With its new highly effective defrost feature (which prevents automatic defrosting when it is not required), the
ZUBADAN System can deliver conditioned heating operation up to 250 minutes in one continuous cycle!
Startup Comfort
One of the key factors of the units newly designed Flash Injection Circuit is that the optimal amount of refrigerant
can be provided to the system via the compressor through a specially designed injection port to ensure a
particularly stable operation. In simple terms, the system allows a quick startup time and continuous heating; even
in low ambient conditions.

Backup Function
(HP400 and HP500 models)
ZUBADAN system ensures an exceptionally high level of reliability by
utilizing a new backup function, which can be easily operated in the
case of a malfunction from an indoor unit remote controller.
Rotation Function
(HP400 and HP500 models)
Running outdoor units alternatively using its newly developed ‘Rotation
Function’, the system is able to ensure an optimum product life cycle for
both of its component units.

High Static Pressure Setting
High Static Pressure Setting up to 60Pa is available. With our new ZUBADAN model, high static pressure setting
up to 60Pa is available by setting the dip switch (0Pa at factory setting) making it ideal and flexible for any type of
application.
Shorter Warm-up in about 20 Min.
With its new improved startup performance, the ZUBADAN system achieves full heating capacity even when
outdoor temperature is as low as -15˚C. Heating capacity, about 20 minutes after startup is improved by 40%
compared to the conventional model; ensuring occupants an immediate comfortable air solution.
