ECO Clean Tank

• Jade-color panel demonstrating anti-bacterial function
• External reinforcement structure without risk of rust

Necessity for anti-bacterial function for the tank

Providing anti-bacterial function to the tank

Inorganic anti-bacterial agent

• Non-toxic anti-bacterial agent of which main ingredient is silver (Ag) ion
• Differences from organic anti-bacterial agent
  -Safe at high temperaturev
  -No volatility and no elution
  -Long sustainability of anti-bacterial function

Bio-ceramic

• Far infrared ray radiator of porous crystaliine material
• Effects of bio-ceramic
  -Activation of water
  -Maintaining freshness and improving taste
  -Removing bad odor and purifying water

Photos of Anti-bacterial Test

We provide perfect hygiene and convenience for cleaning with an external reinforcement system that has no possibility of containing rusty water.

External reinforcement beam
-External reinforcement design that is structurally safe without internal reinforcement material.
-Reinforcement structure focusing on endurance and hygiene.

Outstanding thermal effect(option)
With the excellent insulating effect of the material and single-unit polyurethane thermal material, our tank demonstrates outstanding thermal effect and prevents freezing and dew condensation.(Adapted weather proof-treated thermal cover)

Watertight Construction of the Panel
Maintains perfect watertight function by using tape-type sealant, a PVC foam with an excellent weatherproof function and restoration.

External ladder
-Considering the safety when entering the manhole, the grip part of the ladder is made in round form.
-Easy to use and excellent in appearance.

Roof support/internal ladder
-Used reinforced plastic which is same material for the panel, contains no rust and does have excellent mechanical strength.

Hot dip galvanized bolts
The coated surface is not damaged when assembling with an impact wrench to a thickness of a coating surface more than 40m in thickness.

Drainage structure at the bottom
We use a drainage panel on the bottom to collect and discharge the water.

Internal/External Complex Reinforcement System(3.5mH~5mH reinforcement system)
The water tank exceeding 3mH in height adapts an internal/external complex reinforcement system that minimizes using reinforcement materials inside the tank and secures hygienic and structural safety.
**In particular, in order to prevent erosion due to chlorine gas, the structure without an inside reinforcement stay is applied to the top part.

Internal reinforcement system(1mH~5mH reinforcement system)
Internal reinforcement system provides the followings.

• In the event that the space for installing a tank is narrow, a proper reinforcement system enhances the utility of the installation space.
• By applying a PE coating to the internal-Horizontal reinforcement materials, rust generation is minimized on the stainless steel part on the top part.
• Easy to install by applying a reinforcement system with proper specifications that are suitable for inside and outside.

The ECO Clean Tank provides perfect structural safety based on years of experience and know-how in structural design.

Safety : We pursue the best system through strict design criteria, quality management and reliable structural strength analysis

The basic of structure anlysis is design by safety factors against threshold values. Doha's know-how lies in the optimal safety factor in consideration of external force in the design that is expected based on physical properties after long-term use of SM material for more than 15 years.

In designing, the ECO Clean Tank ignores initial value(100%) of the physical properties of SMC material and considers the safety factor to a minimum value(70%). Therefore, the ECO Clean Tank gurantees long-term endurace.

Free capacity design
Using panels of various sizes, the ECO Clean Tank utilizes horizontal and vertical space at the maximum and those are suitable for an underground reserve tank of large capacity. It operates a corner-type system.

Large Capacity Type

Optimal structural design
Performing structural analysis by the Finite Element Method, we secure reliability for the reinforcement system and panel strength and pursue optimal design.
Inputting all possible factors that might occur, such as hydrostatic pressure, seismic load , snow load, wind load, etc., we evaluate stress and stain.
Focusing on reinforcement of the part having peak stress, we design the safest system.

Specification and space for concrete foundation

Based on PAD production

• Width : More than 400mm
• Height : More than 600mm(including base frame)
• Interval distance : Less than 1m at maximum
• Outline dimension : W, L + 400mm
