The production workshop occupies a large space, and the internal air is not easy to be replaced with fresh air, so the air quality of the workshop is also a major hidden danger affecting the health of workers. Especially in the long-term operation, the harm brought by the dirty air is more terrible than the high-temperature environment. Designers have tried to solve this problem with various schemes, such as adding new fans, adding air purifiers to return air duct, even wearing gas masks for workers, but these can not fundamentally solve the problem. Although new fans bring fresh air into the outdoor, air purifiers also make the air quality into return air ducts clean, but the fundamental problem lies in the long-term use of metal, the inside of the air duct is already dirty and bacteria grows inside, which is not only difficult to ensure healthy air but also counterproductive.
Due to the structural characteristics of the traditional ac air duct, cleaning has always been a big problem. After long-term use, the internal of the traditional air duct is dirty, dusty, rusty, and corroded. At present, there are two cleaning methods, one is manual cleaning, the other is robot cleaning. People can not enter the air duct, so the cleaning is aimless and it is difficult to clean with poor cleaning effect; although the robot cleaning can see the internal situation of the air duct through monitoring, the end branch pipe is too small, the robot can not reach, and the robot cleaning cost so much, most companies can not bear it.
Due to the structural characteristics, Durkeesox textile duct system has the advantage of easy cleaning. After using for a period of time, the textile ductwork can be directly removed and put into the industrial washing machine for cleaning. After cleaning, it can be hung directly. The cleaning is convenient and the cost is extremely low. The shrinkage rate of textile ductwork is only 0.2%. It can be cleaned once every two years, and be used for 100 years; even if it is cleaned once a year, it can be used for 50 years.
URR™ (UNIFORM AIR VELOCITY, REDUCER, RETENTION)-N SERIES
URR perfectly integrates uniform air velocity controlling technology with Internal retention ring system, URR system remain round when deflated, absorbing all advantages of both products, It presents more stable inner air velocity, more balanced inner pressure, better visual pleasing effect, easier installation and higher cost efficiency.
Under the same air supply condition, the internal air velocity curve of ordinary equant round duct is sharply descendant along with lengthwise direction, the air velocity tends to zero at the end cap; UR system can generally ensure stable internal air velocity.
Air Dispersion Direction Diagram of Ordinary Equant Round Air Duct
Due to vector superposition effect, there is wide difference in internal air velocity from inlet to end cap of ordinary equant round duct.
Air Dispersion Direction Diagram of UR System
Uniform air velocity inside UR system results in same air dispersion direction along the duct.
More Balanced Inner Pressure
Static Pressure Curve of Ordinary Equant Round Duct
Generally speaking, the air velocity is rapidly decreasing inside ordinary equant round duct. Since the static pressure regain leads to the increasing of dynamic pressure whereas less on-way resistance, the overall static pressure from inlet to end cap has a certain increase. PAD must be installed to balance static pressure.
Static Pressure Curve of UR System
Since UR system is cone-shaped from inlet to end cap, its on-way resistance is larger than that of ordinary equant round duct. Meanwhile, the internal air velocity is relatively uniform and the static pressure regain is lower. The test result turns out that UR system could basically achieve balanced inner static pressure as long as it is not exceptionally long.
Effectively Slow Down Temperature
Ordinary Equant Round Fabric Duct System
If ordinary equant duct is running with excessively high surrounding temperature or over-length, the inner air temperature lengthwise has a certain rise.The degree of temperature rise is relevant to duct length and temperature difference between insideand outside duct surface.
UR Air Dispersion System
The relatively high axial air velocity of UR system reduces the heating exchange time between the inner air and duct surface, which slows down and reduces the temperature rising. Meanwhile, as the decreasing of surface area along the rear duct results in smaller heating exchange contact area, that is conducive to further slow down and reduce temperature rising. The test result turns out that the temperature rising control efficiency of UR system has been improved for 70% compared with Ordinary equant round fabric duct.
Achieve More Uniform Airflow Distribution
UR System With Multi-Branches
Since the air velocity in main duct of UR system is completely stable and balanced while the included angle between duct surface and branch duct is slightly less than 90°, that is conducive to lead uniform air distribution to each branch.
Ordinary Equant round fabric duct with multi-branches
Different air velocity in main duct of Ordinary equant round fabric duct leads to different airflow supply in each branch, which causes the nearer the branch is to endcap, the more airflow the branch is to receive. ACD is required to balance airflow in each branch.
Where to Use
Post Air Supply Aress
Given high ambient temperature, large airflow and relatively long duct in such areas as machining workshop, URR air dispersion system maintains high and uniform air velocity by continuously changing conicity to achieve even air dispersion and significantly reduce temperature rising.
Large And High-Elevation Facility
Given large airflow and high ambient temperature in high and large space, UR air dispersion system is applied to obtain higher air velocity at each orifice and long air throw distance with aesthetic appearance.
High Demand For Even Air Dispersion
Given the high requirement of even air dispersion along the duct and strict control of end air velocity, the global leading design software Isox is used to calculate and generate continuously variable diameter UR system to identify as the best uniform velocity air dispersion system.
High Demand For Cost Efficiency
Given the high space and large airflow in such areas as logistics warehouse and cold logistics, both effective air dispersion and cost efficiency shall be taken into consideration. UR airdispersion system can not only ensure even air dispersion but also reduce overall cost because of less fabric consumption.

2. Maintenance Period Description
Following is the advised maintenance period of general situation.
2.1 DurkeeSox—EJ 100% Eject without Permeation.
Made of non-porous fabric, and usually installed in higher space, So system cleaning and maintenance requirement is not an immediate concern. According to the different work environment requirements, general we suggest the cleaning period is three to five years.
2.2 DurkeeSox—PE Permeation with Injection
Made of less permeable fabric, most of airflow is distributed through orifices; fabric blockage is not our direct concern. Additional, the system is usually installed in higher space, According to different working status, general advised cleaning period is two to three years.
2.3 DurkeeSox—PS Permeation with Slots
Made of various permeation fabrics, part of air is distributed through fabric, and the system usually installed in lower space, so when it is discovered that fabric is seriously soiled and worked under lower efficiency, or there is obvious dust on the system surface, we need to clean system. According to different working conditions, general advised cleaning period is one to two years. In the cases of extreme dirty, the fabric may happen discolored as the cleaning.
2.4 DurkeeSox—PM 100% Permeation
Usually applications are in refrigerated, cooling system such as food processing, regular and effective maintenance is particular important. If the systems operating in dirty or soiled or long time without maintenance, it may results permeability failure or less life of system, According to the different working conditions, general advised cleaning period is every 3 months to half year is better. When cleaning, take down every part from suspended device, then turn out the dirty surface and washing.
