Daikin ST3 Outdoor Heat Pump Unit (Outdoor Unit Only)

Daikin air cooled magnetic centrifugal chiller have reached an amazing IPLV up to 6.05. The inverter design and high efficiency flooded heat exchanger design greatly improved the model performance taking the energy saving performance of air cooled chillers to an entirely new level. Oil free magnetic bearing design with inverter technology. Ultra low start up current < 2A.

Key Features & Technology

It’s the unique features of Daikin products that makes us the world leader.

The R134a environmentally-friendly refrigerant contains no chlorine atom and poses no harm to the ozone layer. It reduces CO2 emission, mitigates the greenhouse effect and complies with the national low carbon economy requirement.

In comparison with the traditional dry-expansion evaporator, the high efficiency flooded evaporator improves the heat exchange efficiency by more than 30%, enhancing the energy efficiency of unit greatly.

The shaft does not come into contact with the bearing due to magnetic levitation during operation of the maglev compressor, and the design without lubricating oil reduces the operation noise greatly by 8 dB(A) in comparison to the common air-cooled screw unit.

The entire system operates without oil, avoiding thermal resistance formed on the heat exchanger surface after lubricating oil enters the heat exchanger and ensuring higher heat exchange efficiency.

The low startup current of 2 A avoids current impact and mechanical impact, and guarantees the maximum safety of power grid; the unit implements inverter operation and the compressor realizes stepless regulation and output as needed according to the user’s load requirement.
