Pièges Courants Lors du Choix d'une Chambre Climatique: Êtes-vous Tombé dans Ces Pièges?

  • Solutions pour l'industrie, Actualités
Écrit par Shirley
Chef de produit, Doaho Test (DHT®)
When a company invests in a chambre d'essai accessible for the first time—whether to support R&D or production testing—the engineering team is often optimistic, expecting significant improvements in testing efficiency and reliability.
But once the system is up and running, that optimism can quickly fade. Unexpected challenges begin to emerge: the chamber doesn’t fit well within the lab layout, compromising space utilization; temperature and humidity control fall short of spec, leading to inconsistent test data; maintenance proves more complex than anticipated, and operating costs far exceed the original budget.
While these issues may seem unrelated, they usually stem from one root cause: critical missteps during the selection process. In this article, we’ll explore the most common selection mistakes and show you how to avoid them—so your next investment delivers the performance you expect, without the surprises you don’t.

Pitfall 1: Prioritizing Chamber Size While Ignoring Lab Compatibility

Many procurement decisions are driven by the assumption that “bigger is better.” A larger walk-in chamber is often believed to cover more test scenarios. However, larger units typically demand more power, more complex ventilation infrastructure, and more physical space for installation. If the lab environment is not carefully evaluated in advance, such purchases may lead to cramped layouts, rising energy bills, and reduced overall efficiency—hidden costs that erode long-term ROI.

Pitfall 2: Believing a “Universal System” Solves Everything

While modern walk-in environmental chambers offer multi-parameter, multi-condition simulation, so-called “all-in-one” systems tend to be complex by design and costly to maintain. In practice, many users only utilize a small subset of the available functions, resulting in underused features and wasted investment. Matching the chamber’s capabilities to your actual testing needs—not overconfiguring—is key to optimizing both performance and budget.

Pitfall 3: Overlooking Future Expansion and System Flexibility

As a key component of laboratory infrastructure, walk-in chambers are long-term assets. Yet many purchases focus solely on current requirements, without leaving room for future growth or evolving standards. Systems without modularity or upgrade compatibility may become obsolete quickly, forcing costly reinvestment. Choosing a chamber with flexible configuration options ensures it can evolve alongside your testing demands.

Pitfall 4: Underestimating the Value of After-Sales Service and Maintenance

While hardware specifications matter, the long-term performance of a walk-in chamber relies heavily on service quality and technical support. These systems are complex, requiring specialized maintenance and long service cycles. Inadequate after-sales support leads to longer downtimes, delays in R&D timelines, and even greater financial losses. Working with a supplier that offers fast response times and professional support is essential to maintaining test continuity and operational efficiency.

Pitfall 5: Neglecting Data Management and System Integration

Environmental testing today goes far beyond simulating temperature and humidity—it demands precise data acquisition, traceability, and integration. Chambers that lack compatibility with Laboratory Information Management Systems (LIMS) or automation frameworks limit your ability to digitize workflows and modernize test operations. Open protocols and interoperability are becoming critical features for future-ready test labs focused on data intelligence and connectivity.

What Do These Pitfalls Really Cost You?

  • Extended testing cycles and delayed product timelines Inaccurate configurations lead to repeated adjustments and slower development.
  • Inconsistent test results and poor data reliability Inadequate control or incomplete data capture compromises test repeatability and credibility.
  • Disorganized lab layout and low space utilization Poorly matched equipment disrupts workflow and resource efficiency.
  • Surging maintenance costs and budget overruns Frequent breakdowns and complex upkeep increase both manpower and financial burdens.
  • Inability to meet future test standards Non-upgradable systems limit your capacity for innovation and scalability.

How to Choose the Right Walk-in Chamber? Three Core Principles

Définir un profil clair d'exigences de test

Clarify your sample size, weight, environmental conditions, test complexity, and usage frequency. This helps you avoid over-purchasing and ensures the chamber aligns precisely with your actual needs.

Match Equipment to Your Lab’s Physical Conditions

Assess space availability, power supply, HVAC setup, and infrastructure before making a decision. Select a chamber whose specs fit your site environment to ensure long-term stability and efficiency.

Plan for the Future with Scalable and Integratable Design

Prioritize modular systems with upgrade options and compatibility with mainstream management platforms. This ensures your testing capacity grows with your business and supports automation and digital transformation.

Les gens demandent aussi

Quelles sont les causes des résultats incohérents dans les tests de choc thermique, même lorsqu'une chambre calibrée est utilisée ?
Les résultats incohérents proviennent souvent de gradients thermiques cachés à l'intérieur de l'échantillon, et non d'un dysfonctionnement de la chambre. Alors que l'air de la chambre peut se stabiliser rapidement, la température interne des échantillons denses ou complexes est à la traîne, provoquant un stress thermique inégal. Cela peut conduire à des microfissures ou à une défaillance de la soudure que les capteurs standard ne détecteront pas. Pour éviter cela, utilisez des thermocouples intégrés ou une imagerie thermique infrarouge pour surveiller les températures centrales et ajuster le moment du transfert en conséquence.

À quelle fréquence une chambre de choc thermique doit-elle être calibrée et entretenue ?
En raison des cycles thermiques à haute fréquence entre des températures extrêmes, des composants tels que les capteurs, les joints et les systèmes de réfrigération se dégradent au fil du temps. Il est recommandé d'étalonner les capteurs de température tous les 6 à 12 mois et de mettre en place un plan d'entretien préventif comprenant la vérification des joints, le nettoyage des serpentins et la surveillance des diagnostics du système. Les chambres avancées, comme celles de DHT®, disposent de systèmes d'auto-diagnostic et de fonctions d'auto-étalonnage pour réduire les temps d'arrêt et garantir une fiabilité à long terme.

Un modèle de chambre de choc thermique peut-il répondre à toutes les normes industrielles (par exemple, IEC, MIL-STD, GB/T) ?
Pas nécessairement. Bien que de nombreuses chambres supportent une large gamme de températures et des vitesses de transition rapides, des normes comme IEC 60068, MIL-STD-883, et GB/T 2423.22 présentent des différences subtiles dans les limites de temps de transfert, les durées de récupération, et les exigences de temps de maintien. Pour assurer la conformité, choisissez une chambre avec des profils programmables et consultez le fabricant (comme DHT®) pour une configuration adaptée à vos besoins spécifiques de certification.
