Product description
Commercial and Industrial Rooftop Air Conditioner is designed as an all in one solution and additionally useful for consolidating space. Free Cooling Rooftop Packaged systems are popular in regions where construction favors a single cabinet system rather than a split system, which has both an outdoor and an indoor unit. Typically, Rooftop air conditioners are installed outdoors at ground level. In certain instances they may also be installed on the roof for horizontal or down flow designs. Unlike ducted split air conditioning unit, in a packaged system, most components are in one cabinet. Whether you're looking for cooling only, heat pump type or heat recovery type, we have the right choice for you.
Application areas
● Large and light commercial buildings (Retail, Airports, Restaurants, shops, petrol stations-)● Cinemas, Theaters
● Industrial buildings and Logistic centers
Why this choice?
● Energy efficient solution● Cost effective package for fast and easy installation
● Multiple heating options available
● Fresh air control and free cooling management
● Wide choice of communication interfaces
Structure
Panels and frame are made from galvanized steel protected with polyester powder painting to ensure total resistance to atmospheric agents.
Direct expansion coils with condensate drain tray.
Hermetic compressor
High efficiency scroll compressor for the whole range, with built-in thermal overload cut-out and crankcase heater, mounted on rubber vibration dampers.
Ripple type acoustic insulation for compressor section, and thermal insulation for coil and fan section, low noise.
Centrifugal fan
Forward curve centrifugal fans for air treatment section and axial fans for condensation section.
Front, side and underside air discharge of the treatment unit.
High external pressure, long air supply distance.
Electric panel
Electric panel consists of breakers and contactors for compressors and fan motors, phase sequence relay and other necessary protection devices for the main components.

Economizer and Free Cooling
It is one of the most important features of this rooftop as it maximise seasonal efficiency by reducing the use of thermodynamic cooling in mid season.
Thermodynamic cooling can be replaced by Free Cooling when outdoor temperature is below the building set point saving up to 15% on annual energy consumption.
Rooftop units are supplied with economizer and fresh air hood to improve comfort through better fresh air management and allow energy savings with free cooling.
● Gravity exhaust damper
Gravity exhaust damper Installed with economizer assembly, gravity exhaust damper relief pressure when outside air is being introduced in the system. It is a cheap and smart way to avoid over pressure in a building.
● Power exhaust fansInstalled with economizer assembly, it provides exhaust air pressure relief when high levels of fresh air are being introduced in the system.
Interlocked to run when return air dampers are being closed and supply air blower is in operation. The extraction fans run when outdoor air dampers are at least 50% open (adjustable). It is also overload protected. A gravity exhaust damper is supplied with this option to prevent air from entering the unit during shutdown. The power exhaust fans have been size to exhaust 50% of the nominal air flow of the unit.

* Performance values refer to the following conditions:
Cooling: room air temperature 27.0°C DB RH 50%, ambient air temperature 35°C;
Heating: room air temperature 20.0°C DB, ambient air temperature 7°C DB / 6°C WB.
** Noise level measured by adopting average value in the noise lab with background noise of 25 dB(A), at a distance of 1.5m high fan speed.
