AC Rooftop adalah Suatu pendingin ( AC ) yang letaknya berada di atap bangunan. Sistem itu menyatu (tidak terpisah), dan terangkai langsung dengan pekerjaan ducting dari posisi unit AC di atap, sama seperti halnya AC split biasa, AC Rooftop mempunyai beberapa variasi ukuran untuk mengakomodasi ukuran ruangan yang didinginkan.
UATQ-C series comes with high efficiency scroll compressors, optimized heat exchangers and high-performing fans which enables the unit to deliver top performance in both standard and high ambient temperature conditions. At the same time, it also ensures high energy efficiency and reduced power consumption.
2.Wide operating range
UATQ-C series rooftops are specifically designed for high ambient application and are capable of operating at an outdoor ambient of up to 52°C.
3.Flat top design
The units’ flat top design allows it to be stacked up in the warehouse and during transportation. This ensures both warehouse and container space are optimized.
Additional piping works are not required as both the indoor and outdoor sides are pre-connected. The horizontal air discharge from the top and return air from the bottom makes the duct design straightforward. Once the ductwork is installed, the remaining is just to connect electricity to the unit.
5.Air discharge and air return
The UATQ-C series is available in horizontal air discharge only. It is designed with air discharge on the top, and return air from the bottom for easy duct design.
6.Independent refrigerant circuit
The unit is designed with two independent refrigerant circuit, where user can control each individual system separately. This also allows the unit to run at part load when less capacity is required.
*Applicable for UATQ120C and above only
7.External 3rd party testing
The UATQ-C series have undergone stringent 3rd party testing by INTERTEK, an internationally recognized certification body, to verify on its designed performance data.
8.Auto random restart
When the unit stop suddenly due to power failure during operation, it will automatically restart its last setting condition once the power is resumed. However, the compressors will restart randomly if more than one unit are installed under the same phase of power.
9.Safety protection features
> High and low pressure protection
> Phase sequence protection
> Compressor and current overload protection
> Minimum compressor run and off time protection
> Sensor fault indication
10.Anti-corrosion heat exchanger
Hydrophilic Gold Fin coated coil is offered as a standard coil to further prolong unit life span under corrosive environment. Coil guard is incorporated to protect heat exchanger from accidental damage which may happen during transportation, handling and installation.
Microprocessor Unit Controls
UATQ-C series is equipped with microprocessor controller. Every unit comes with a microprocessor operated handset. It has a built-in anti recycle timer to prevent compressor from short cycling. The compressor, condenser motor and evaporator motor starts up in sequence to prevent power surge. Microcontroller records the compressor run time internally to ensure balance usage of compressor.
