Case Study: Dezenno Conquers Toyota Hung Yen's Lab - The Precise Humidity Control Solution When Other Brands Failed

Context: "Made in Japan" Standards Meet Vietnam's Climatic Challenges at Toyota Hung Yen

Toyota is a global symbol of quality and reliability. To uphold the legendary "Made in Japan" standard at its Vietnamese factory, every stage of the production and inspection chain must adhere to the strictest technical requirements. One of the most critical areas is the production lab at the Toyota Hung Yen factory – where components and materials are quality-tested before being sent to the assembly line.

The challenge for this lab was to maintain an environment with a very wide and variable operating range, from 10-40°C and 20-65% RH, to simulate various operating conditions. However, with Vietnam's tropical humid climate, maintaining such stability across this broad range is an enormous challenge.

When Other Solutions "Failed": The Challenge of Precise Humidity Control

A key detail of this project is that before approaching DeAir, Toyota Hung Yen had tested humidity control solutions from other brands without success. From an expert perspective, these failures often stem from the inherent limitations of traditional condensing technology when faced with a difficult problem:

• Instability: The previous units could not maintain a set RH% level stably. The humidity level constantly fluctuated with the changing weather outside, affecting the accuracy of the inspection results.
• Poor Low-Temperature Performance: When the lab operated at the lower end of its temperature range (below 18-20°C), condensing dehumidifiers became nearly ineffective because their cooling coils were not cold enough to condense water vapor from the air.
• Lack of Precision Control: The control systems lacked the precision to meet the strict monitoring and data logging requirements of an international-standard laboratory.

The problem was no longer just "we need a dehumidifier," but "we need a technologically superior, stable, and absolutely precise solution."

Dezenno Steps In: The Rotor Technology Solution from DeAir

Faced with this difficult challenge, DeAir consulted and implemented its most advanced technological solution: the Dezenno rotor dehumidifier. The success of this solution comes from core technological differences that comprehensively solve the issues where other brands "gave up."

The Result: Stability & Reliability - The Foundation for Toyota Quality

DeAir's Dezenno rotor dehumidifier solution was 100% successful in providing a stable, precisely controlled environment that met Toyota's strict requirements. This stability allows Toyota to conduct its quality inspection processes with confidence, eliminating environmental variables and thereby ensuring the final product quality for which the brand is globally renowned.
