Air Cooled Package Unit in Australia
Looking for a reliable air cooled package unit in Australia? Our systems are engineered for efficiency, durability, and compliance with Australian energy standards. Whether you’re managing a commercial building, data centre, or industrial facility, we provide HVAC solutions designed for local climate conditions and business needs.
What Is an Air Cooled Package Unit?
An air cooled package unit is a self-contained HVAC system where all major components — including compressors, condensers, and evaporators — are integrated into a single outdoor package. Unlike water cooled systems, it uses ambient air to remove heat through a condenser coil and fans, eliminating the need for cooling towers or water lines.
​
This makes air cooled package units an attractive choice for Australian businesses that need a cost-effective, space-saving, and energy-efficient solution.

Our Air Cooled Package Units
This platform provides you with a full line of nominal capacities from 100 to 300 MBH. This unit is suitable for use in mobile homes, commercial homes and conventionally constructed residential and commercial buildings where horizontally-ducted system is preferred.
​
Evaporating units consist of an evaporator coil, centrifugal forward curve blower, pre-filter and enclosed in a single skin galvanised steel casing. There are design configurations with hanging or floor mounted type.
Each condensing units consist of a condensing coil, condenser fan with motor, compressor, refrigerant circuit and enclosed in a single skin galvanised steel casing.
Casing Construction
As standard, the casing is constructed with electro galvanised mild steel sheet to ensure units casing rigidly and eliminate vibration. The casing is painted with epoxy polyester powder coating for excellent finish, weather protection and corrosion resistance against severe external conditions.
Blower
The standard fans used for evaporator are forward curve Double Width Double Inlet (DWDI) centrifugal fans. The blowers are belt driven with motors 380- 415V /3-Phase / 50 Hz.
​
The standard fans used for condenser are propeller type with aluminium impeller. The propeller fans are direct driven with motors 380-415V /3-Phase / 50 Hz.

Coil
All coils designed to deliver their respective duties at optimum performance at all design conditions and to meet a wide range of applications and requirements. As a standard, coils are manufactured from seamless copper tubes of OD 9.52mm (3/8inch).
The cooper tubes are mechanically expanded into collar of corrugated aluminium fins to provide a continuous compression bond over the entire finned length for maximum heat transfer rates. The standard number of fins per inch are 10, 12, 14 FPI (fin pitch 3.3, 2.5 2.1, and 1.8).
All coils are factory tested at no less than 300 psig air pressure underwater. Due to the huge variety of coil input conditions, the coils calculation and selection is optimally done based on a fully wetted coil by selection software integrated in the unit selection software to match the required conditions.
​
Direct expansion coils are equipped with a properly - sized expansion valve and distributor to ensure equal refrigerant fed to all circuits. The number of circuits is chosen to provide optimum heat transfer and reasonable refrigerant velocity and pressure drop so as not to trap any oil in the coil tubing.
The headers are made of seamless copper pipes. The inlet and outlet connections are sealed against unit panels by rubber gaskets as standard wherever coil connections protrude through the casing.
Utilizing the full available unit cross section area, coils are mounted in the unit casing on noncorrosive slide rails to allow for easy coil slide in - slide out when required.
​
As standard, coil casings are made of galvanized steel sheet. Stainless steel 304/316L casing is offered as option.
Filters
The units are equipped with 1" thickness washable filter synthetic fibre filter, Class G2. The filter is designed to be easily withdrawal and renewal of filter cells.
Drain Pan
In order to remove the condensate, the drain pan is supplied under the cooling coil which covers the entire coil section. The drain pan, is made from powder coated galvanized steel metal or painted mild steel.
​
The drain pan is designed with a slight downward slope towards the drain pipe to ensure quick drainage and no water accumulation in the drain pan when AHU is in idle. The drain pan outer surface is insulated by 10mm closed cell PE foam insulation to prevent condensation.
Compressor
The condenser units come with high efficiency, low noise and reliability scroll compressor.

Benefits of Air Cooled Package Units in Australia
1. Energy Efficiency
Air cooled package units achieve a high coefficient of performance (COP), meaning they provide more cooling or heating output per unit of electricity consumed. This translates to lower running costs for businesses compared to older HVAC technologies.
2. Easy Installation & Maintenance
Since the system is fully self-contained, installation is quicker and requires less infrastructure compared to water cooled units. Maintenance is also simpler, with fewer moving parts and no cooling towers to manage.
3. Space-Saving Design
With compact dimensions and rooftop installation capability, air cooled package units are ideal for urban commercial buildings where indoor mechanical space is limited.
4. Reliable in Australia’s Climate
Engineered to perform in high outdoor temperatures, air cooled systems are perfectly suited for Australia’s hot summers. Their outdoor installation also makes them ideal for coastal cities where space and ventilation are at a premium.
