Commercial Building
This is a commercial building.
The management of water in commercial buildings is a two-fold process, encompassing both ductwork and cooling systems. The primary objective is to maintain unobstructed waterways.
The piping system is designed for straightforward drainage, and the pipes are susceptible to changes in water quality and the composition of the pipes themselves. Iron pipes are prone to corrosion, hard water causes scale deposits, and there are numerous bacteria and algae in the water, which produce biofilms and have implications for public health.
Cooling circulation systems are designed to continuously recycle the same water, using heat exchangers to remove waste heat from the system. During the circulation process, a portion of the water evaporates, resulting in the accumulation of salt. Despite the regular replenishment of water, the risk of scale and rust formation in the pipes of the hydronic cooling system remains.
TETRADOM quantum devices are designed to prevent and solve this problem.

Commercial Building
(Beijing,CHINA)
The main issues that need to be addressed are as follows:
The total circulation is 200 tons.
The daily lotion production is: The quantity is approximately 7-8 tons.
The water source is city tap water.
The water treatment method employed is a chemical one.
Chemical methods should be employed to address issues such as rust, corrosion, bacteria, and algae in the cooling circulating water system. The expense of chemicals, manual maintenance and drainage fees is considerable, the results are not optimal and the heat exchange efficiency is low.
We would like to propose a solution to this problem.
Installation
The product can be used in the following locations:
Please install two WR-H 10125 quantum rings in front of the condenser of the water-cooling unit, two WR-H 10125 quantum rings in the air-conditioning chilled water system, and one WR-H101451 quantum ring in the heating system of the thermal station.
Effect of Use：
The installation took 6-10 months, and no chemicals were added during this period.
- The inside of the condenser is clean and free of scale, rust and mud.
- There is a good heat exchange effect.
- There is a greatly reduced water discharge and an increased concentration ratio.
- The cooling tower is filled with clean materials.
- Overall operating costs are reduced.
Summarize
TETRADOM quantum loop is a more effective solution than the original chemical method. After four months of operation, the equipment performed without any issues and produced rust particles flowing out of the water, which proved that the original scale and rust had been removed. The loop improves heat exchange efficiency and saves energy, while reducing water emissions and saving water bills.

Pain Points:
It has been standard practice in the air-conditioning industry to use chemical dosing methods to treat circulating water in cooling systems. However, in June 2011, high temperature alarms were triggered in the central air conditioning condenser, and the temperature difference between the inlet and outlet water of the heat exchanger remained relatively constant.
Following an inspection of the condenser heat exchanger in July, it was discovered that there was a significant amount of scaling inside the unit, which was affecting the efficiency of the heat exchange process.
Installation:
Two DN200 quantum rings were installed in August.
Effect of Use：
Following the installation of the quantum ring, the addition of a chemical scale and rust inhibitors was discontinued. The condenser system does not feature a high temperature alarm, with the temperature differential between the inlet and outlet water ranging between 5 and 8 degrees. The condenser heat exchanger was opened again in November 2011. The heat exchanger pipe surface was found to be clean and free of any sludge, scaling or other debris. This has resulted in a significant improvement in heat exchange efficiency.
Summarize
Quantum water treatment equipment is highly effective at removing rust and scale from air conditioning cooling circulating water systems. It offers a complete replacement for chemical treatment methods. The product is straightforward to install and does not necessitate any dedicated maintenance. This product is ideal for use in commercial buildings and represents the optimal solution for water treatment in cooling systems in such premises.
