Bringing a year round comfort solutions to
extreme climates
CITY MULTI ZUBADAN series combines the ultimate in application flexibility and powerful cooling and heating
capabilities to deliver precise comfort even in the coldest days of the year down to -25
˚C.
The technology behind this is a Flash Injection circuit which provides optimum amount of refrigerant to the system
via a compressor through a specially designed injection port to ensure a particularly stable operation. With this,
ZUBADAN can provide a full heating performance even at -15
˚C and continuous heating for up to 250 minutes in
one continuous cycle, ensuring a phenomenal heating performance at low temperatures.

Stable Heating Performance even at -15˚C
Expanded Heating Operation down to -25˚C
Using an industry first ‘Flash-injection
Circuit’, the ZUBADAN System is able
to provide FULL heating performance in
ambient temperatures as low as -15˚C.
…furthermore, from a previous LOWEST
operating ambient temperature of -20˚C,
the ZUBADAN System pushes the
boundaries of technology to give heating
in ambient temperatures as low as -25˚C.
