Product Description

Rooftop Packaged Unit With Economizer is an optional for Rooftop Packaged Unit. The standard simple control logic as below: 01.in cooling or heating mode, it is 100% return air condition, that means, just return air damper open, fresh air and exhaust air damper closed. 02.In free cooling mode, it is 100% fresh air condition, that means, just fresh air damper and exhaust air damper open, return air damper closed. 03.The fresh air damper, return air damper and exhaust air damper are on/off type. 


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


Characteristics
01. 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.
02. 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.
03. 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.
04.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.
05. Easy operation line controller
