If your cleaning projects primarily involve scale, rust deposits, and sediment removal from small-diameter heat exchanger tubes in central air conditioning condensers, chillers, and shell-and-tube heat exchangers—and you require equipment that ...

After prolonged operation of coke oven gas primary coolers in coking plants, deposits of naphthalene, tar, coal dust, scale, and other materials accumulate on heat exchange tubes and related passages. As deposits increase, some tubes may experience r...

In many metro ventilation duct cleaning projects, the most challenging part is not the large main ducts, but the small to medium-sized ducts located in areas that personnel cannot access. These ducts typically have limited space, preventing direct en...

In industrial processes using sodium carbonate or high-concentration salt-bearing media, heat exchangers may experience tube wall crystallization, salt deposition, and composite fouling after long-term operation. As deposits accumulate, the internal ...

In many fresh air system cleaning projects, the most challenging part is not the large main ducts, but the fresh air branch ducts in residential buildings, hotels, hospitals, office buildings, and similar structures. These ducts typically have smalle...

When concrete enters conduit pipes or embedded pipes during construction, restoring flow is often difficult using conventional tools. For hardened concrete blockages, the pipe condition should first be confirmed, then an appropriate mechanical unclog...

During long-term operation of central air conditioning ducts and industrial ventilation pipes, dust, particulates, and other deposits accumulate on the inner walls. For short-distance ducts, conventional flexible shaft cleaning equipment may be suffi...

After scale, rust deposits, and slime accumulate in condenser tube bundles, water flow and heat exchange performance are gradually affected. For water-system equipment such as central air conditioning chillers and shell-and-tube heat exchangers, mech...

Cleaning branch ducts in central air conditioning systems differs significantly from cleaning main ducts. Branch ducts typically have smaller diameters, limited interior space, and may include round ducts, rectangular ducts, horizontal ducts, and ver...

After extended operation of vertical tube heat exchangers, the interior of heat exchange tubes tends to accumulate scale, material deposits, salt scale, crystallized deposits, and other hard fouling. As deposits increase, the effective tube diameter ...

For construction and engineering contractors, the most challenging pipe blockages are not ordinary sediment or debris—they are pipes where concrete has fully cured and solidified inside the line. Once embedded pipes, conduit pipes, drainage pip...

When tube bundles in a falling film evaporator become blocked, a single cleaning method is rarely sufficient. Soft deposits may be addressed with water washing or circulation cleaning; certain soluble scale types may respond to chemical cleaning; how...
