High Efciency
The Acson rooftop unit is supplied with high efciency and reliable scroll compressor (except ART 80/100/150/
200 AR).
Package Unit
Dubbed the “Plug and Play” equivalent in the air-conditioning industry, the single unit conguration allows hassle
free installation. No additional piping work is required as both the indoor and outdoor sides are pre-connected.
Refrigerant is factory pre-charged to ensure clean and efcient operation.
Flexibility Of Air Supply
Acson rooftop unit uses a belt driven fan such that the air volume and static required can be adjusted according
to the requirement. This exibility allows for wider application.
Flat Top Design
Acson rooftop unit’s at top design allows for maximum utilization of warehouse and container space.
Electrical Control Capability
All series are equipped with our Electronic Remote Controller (SLM and Sequential LCD). The Sequential LCD
features 7 days programmable timer, compressor run/error status, cool/heat/fan/dry/auto modes, etc, while the
SLM features a 15 hour delay timer, cool/heat/fan/dry/auto modes, etc.
Part loading of system capacity is now possible with the use of our Sequential PAC (Package Air-Condition)
control for multiple compressor Acson rooftop units (A(4)RT150/200/250/300/360/420 A/AR).
