Ducted Fixed Speed

– Ducted Fixed Speed

The efficient design makes the Ducted unit especially discreet. Ducted units can be installed in multiple points to thoroughly aerate each part of a space.

– Durable Protection Drainage System

The special design of the drain pan makes condensation water flow smoothly without water leakage, and prevents rust. When the drain pipe is clogged and the water rises to a certain level, the water level switch will float and send the signal to turn off the unit.

– Built-in drain pan

Compared with outside drain pan design, the new built-in drain pan can reduce dust adhesion, and avoid water leakage.

– Wide ESP range

A wide ESP range means PRIMAIRY is suitable for spaces with many discrete areas, including corners and recesses. Multiple outlets can be connected to the ducted unit
to ensure a uniform gust of air around a complex space. A system can be set up in a short time and will run reliably into the future.

– Compact design

This compact design minimizes the space between the cement and dropped ceiling, allowing a higher space within the room.

– Flexible air return from bottom or rear

Depending on different space layout, the installation will be highly flexible.

– WIDE AMBIENT TEMPERATURE RANGE

High cooling performance within a wide ambient temperature range.

– High Efficiency Compressor

"Powerful cooling performance at standard and low ambient temperatures:
High efficiency attributed to high performance twin rotary compressor.
Twin rotors balances out centrifugal load resulting from rotation. Reduce compressor vibration, lower noise level, and increase reliability."

– Variable motor fan speed

Optimized fan speed in outdoor unit based on actual load for higher efficiency and more energy saving.

– HIGH EFFICIENCY FIN

HIGH EFFICIENCY HEAT EXCHANGER

– Hydrophilic Aluminum Fin

A hydrophilic aluminum fin enhances heat exchanging performance by increasing water mobility on fin surface and preventing water droplets from forming blockage between fins. The blue coating enhances protection from corrosion resulting from environmental and microbiological factors, increasing reliability and ensuring performance.

– Refrigerant Leakage Detection

"The indoor unit will stop operation automatically and show an error code when the refrigerant charging amount is lower than 30%, which can avoid the compressor being damaged by high temperature due to refrigerant leakage.
When the refrigerant charging amount is between 30%~80%, the unit will judge itself if showing an error code is necessary. This feature can also better ensure the heat transfer efficiency and the safety of the unit."

– High Reliability of Compressor

"Viscosity testing was taken for compressor in order to ensure the reliability of the running."

– Compactness and Lightness

"Free of unnecessary or weighty components, each unit can be carefully slid into place by the installation team."

– More flexible piping

"Both short and long piping may be applicable to the installation needs of different sites. The right placement of the indoor unit is key to distributing the air properly.
Long piping and large height diﬀerence Up to 50m piping run and 30m height applications can be covered, high flexibility in installation configuration."
