Product Description

rooftop air conditioning unit

1) BRIEF INTRODUCTION AND FEATURES
Rooftop air-conditioning unit is DX air-cooled type, combined of the refrigeration system, control systems and
different air handling sections, achieving cooling, heating, dehumidification, humidification, air purification,
sterilization and other functions.Complete with a wide cooling capacity range, no need cooling water system, omit
the dedicated room and complex cooling towers, water pumps and the corresponding pipelines, control device. Unit
usually mounted on the roof or other outdoor location, don't need dedicated room, which greatly save the cost of
civil work. Besides, It's easy to install--- only to connect the duct then power on to run, which also save the cost of
maintenance.


2) Main Unit Descriptions
1) Efficient and Energy-saving.
Each outdoor unit incorporates high efficiency scroll compressors.
Coils use high efficient inner screw copper tube for better heat transfer.
Fresh air non energy dissipating cooling in transient season, can adjust air volume what the fresh air system
required.
OEM energy recovery device.
2) Durable( corrosion and rust protection).
Our packaged systems are built tough towithstand all weathers.
Their durable construction ensures a long life and excellent return on your investment.
The outdoor air coils' aluminum fins could be epoxy coated for extra protection in corrosive environments, e.g. salt
laden sea air.
Blue-fin type coils, epoxy resin fin coils as well as the copper fin coils are also available as an option.
Cabinets are constructed from high grade steel - polyester powder coated for all weather protection.
External fasteners are stainless steel or galvanized type.
Corrosion resistant drain trays are also included.
Designed to evacuate rain water and condensed water easily from the unit.
The opening for the connection side ducts are protected
so that water will not splash on the joint between the duct and unit panel.


3)Safety.
Complete with various protecting function.
Pass kinds of safety tests.
4) Easy service.
Quick release fasteners are provided on electrical and compressor panel.
The units are equipments with access door to all components that may require maintenance or service.
The liquid sight glasses are visible and easy to find.
Access to the control circuit and compressor section is independent of the cooling or heating operation of the unit.
5) Options.
Electric heater, hot-water heating, steam-heating unit.
Manul/electric fresh air damper, plug fan, dedicated exhaust fan air filter dirty alarm device.
Energy recovery device.
