Performance Comparison Between DINGHENG Solutions And Industry Average

Actual test表明，DINGHENG’s optimized equipment design has obvious advantages in energy saving, operation stability and service life, the key performance data contrast is shown below:

Industry consensus is that the integrated equipment supply + installation mode can reduce the total project cost by at least 14% compared to separate procurement from different vendors, according to 2026 global chemical equipment manufacturing association statistics.

DINGHENG Quality Control And Safety Compliance System

From project cases of DINGHENG over the past 18 years, zero major safety accident has been recorded among all delivered projects, thanks to its strict 7-layer quality inspection mechanism running through the whole production process.

Raw Material Incoming Inspection Standard

All contact parts that directly touch aluminum sulfate solution use 316L stainless steel, which has strong acid corrosion resistance, and each batch of raw material will be sent to third-party testing institution for composition verification before processing.

Pressure Test And Leakage Detection

All high-pressure reaction tanks and evaporators will go through 1.5 times of rated working pressure hydraulic test, and 100% air tightness detection before leaving the factory, to avoid hidden leakage risks during long term operation.

DINGHENG Client Success Cases Representative

In practice, DINGHENG has tailored custom solutions for clients with different production demands, covering small family-owned workshops and large-scale municipal water treatment chemical production bases.

2025 Indonesia 12TPH Solid Aluminum Sulfate Project

This client originally planned to import separate equipment from 3 different vendors, but DINGHENG’s full turnkey solution helped them cut total investment by 17%, and the project reached full capacity 15 days ahead of scheduled time, with annual output reaching 90000 tons.

2024 Germany 5TPH Food Grade Aluminum Sulfate Project

DINGHENG optimized the filtering system for this client, making the final product heavy metal content far below EU food additive standard, and the project has passed local TUV certification at first acceptance test.
