Make-Up Rooftop air conditioner unitBRIEF INTRODUCTION AND FEATURESRooftop 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.
GENERAL INTRODUCTIONVENTTK® is one of Chinese largest manufacturers of HVAC system products.
The company has been supplying units to the commercial, industrial markets.
Like Singapore, America, Vietnam, UAE, Australia, Korea, Russia Bahrain, Kazakhstan etc. more than 15 years.
Our mission is to provide the most competitively priced, reliable and efficient air conditioning equipment available to the international market.
Our FLWKR series units are single packaged units which are factory assembled,tested and shipped complete with compressor,evaporator and condenser coils, fans and controls.
These packages are designed for outdoor installation mainly, or on ground level, and as well as indoor installation as optional with centrifugal condensate fan.
They may be used for cooling only or heat pump, and efficient both when heating and cooling.
If cooling only model, you may add the Electric heater for heating backup.
The units are ideal for residential, commercial and industrial applications.
Quality design and construction make Shenglin air-cooled rooftop package units with hermetic scroll compressors the preferred applications and easy installation and maintenance.
