Intelligent Humidity Control for FTIR Accessories

The FTIR Moisture-Proof Box Desiccant utilizes a high-performance electronic dehumidifier core and a microcomputer humidity control system. It offers a humidity control range of 25% RH to 50% RH, ensuring optimal storage conditions for FTIR spectrometer accessories. The system employs a recyclable and regenerative moisture-absorbing molecular layer membrane to control humidity, eliminating the need for consumables.

Energy-Efficient Design with Real-Time Monitoring

Designed for energy efficiency, the moisture proof box operates with low power consumption and features noise-free operation. A front-mounted LCD screen displays real-time temperature and humidity levels, allowing for easy monitoring. In the event of a power failure, the system continues to dehumidify using its chemical moisture absorption compensation function, ensuring that the humidity increase within 24 hours does not exceed 10%.

Technical Parameters Summary

Product Specifications & Engineering Highlights

Our advanced moisture proof box units are designed with industrial-grade microcomputer humidity control systems, offering a reliable precision regulation range of 25% RH to 50% RH.

• Zero-Consumable Dehumidification: Utilizing a highly efficient, recyclable, and regenerative moisture-absorbing molecular layer membrane, our systems eliminate the ongoing cost and hassle of traditional desiccants.

• Airtight Structural Integrity: Each airtight moisture proof container features high-density sealing technology and top-mounted damping hinges. This structural design ensures maximized interior space utilization and prevents external ambient air infiltration.

• Power Failure Protection (Chemical Compensation): In the event of an unexpected lab power outage, the cabinet automatically switches to its chemical moisture absorption compensation mode. It restricts the internal humidity increase to less than 10% within a 24-hour window, ensuring uninterrupted protection.

• Real-Time Monitoring: Equipped with a front-mounted LCD screen providing high-accuracy dual display for both temperature and relative humidity.

Comprehensive Industry & Laboratory Applications

Our moisture proof storage boxes are widely deployed across high-precision research and industrial sectors where contamination-free, humidity-controlled storage is non-negotiable:

• Spectroscopy & Optical Research: Perfect for storing KBr, NaCl, CaF2, and ZnSe crystalline windows, pellets, pressed dies, and sensitive beam splitters. It prevents surface fogging, structural degradation, and chemical deliquescence caused by ambient humidity.

• Pharmaceutical & Biomedical Analysis: Used in QA/QC laboratories to protect reference standards, hygroscopic powder samples, and FTIR sampling accessories (such as ATR crystals and transmission cell holders) from moisture absorption prior to analysis.

• Advanced Materials & Semiconductor Labs: Ideal for storing moisture-sensitive substrates, wafers, electronic sensors, and precision calibration targets that require a strictly regulated relative humidity environment.

• Chemical & Petrochemical R&D: Protects precise analytical instruments' auxiliary parts and consumables from corrosive moisture damage, ensuring the long-term reproducibility of spectroscopic data.

Core Components & Technical Infrastructure

The reliability of each Hench moisture proof box relies on industrial-grade, heavy-duty components designed for continuous laboratory operations:

1. Regenerative Electronic Dehumidification Core: Features a high-grade, multi-porous synthetic molecular sieve membrane. This core operates mechanically without the need for chemical desiccant replacements or water drainage systems.

2. Microcomputer Intelligent Control Unit: Built with a programmable microchip processor paired with an imported, high-precision digital humidity and temperature sensor. It ensures real-time detection and rapid-response dehumidification triggering.

3. Reinforced Airtight Enclosure: Constructed from 1.2mm premium cold-rolled steel with an anti-corrosion, anti-static (ESD-safe) powder coating. The perimeter is sealed with a high-performance magnetic rubber gasket to isolate the internal environment entirely.

4. Top-Mounted Damping Hinge Structure: Engineered with a specialized upper-cover vertical opening mechanism. This optimizes laboratory bench space, reduces mechanical vibration when opening, and ensures smooth, controlled closure to protect fragile glass or crystalline contents inside.

Advanced Working Principle

Our airtight moisture proof container operates via a fully automated, cyclical physical adsorption and desorption process managed by the microcomputer system:

[Ambient Detection] -> [Auto-Activation] -> [Molecular Adsorption] -> [Passive Power-Off Safety]

• Phase 1: Dynamic Moisture Adsorption (Internal Preservation) The high-precision sensor continuously monitors the internal atmosphere. When the relative humidity exceeds your preset target (e.g., >35% RH), the internal shutters of the dehumidification core open. The highly porous molecular sieve membrane rapidly traps water molecules from the air via physical adsorption, dropping the humidity back to the safe zone without generating heat or noise.

• Phase 2: Automated Thermal Regeneration (External Exhaust) Once the molecular sieve reaches saturation, the microcomputer controls the internal shutters to close (sealing the storage chamber) and opens the external exhaust vents. A brief, low-power internal heating element activates to desorb and expel the trapped moisture outside the cabinet. After cooling, the system resets for the next cycle—achieving a 100% maintenance-free, zero-consumable lifespan.

• Phase 3: Fail-Safe Chemical Compensation In the event of a sudden laboratory power outage, the mechanical shutters default to a closed state, locking the internal environment. The structural molecular matrix continues to provide passive chemical moisture absorption, restricting the total internal humidity rise to less than 10% RH within a 24-hour period.

FAQ – FTIR Moisture-Proof Box

What humidity level is safe for FTIR storage?

FTIR instruments generally require a low-humidity environment to ensure stable optical performance. In most laboratory conditions, maintaining 25%–50% relative humidity (RH) is considered safe. However, for high-precision spectroscopy applications, lower humidity levels are often recommended to reduce the risk of moisture interference with infrared signals and optical components.

Can this box be used for other lab instruments?

Yes. Although it is designed for FTIR systems, the moisture-proof box can also be used for other sensitive laboratory instruments and materials, such as analytical balances, optical components, electronic devices, semiconductor samples, and chemical reagents that require controlled humidity storage.

How often does the desiccant need replacement?

The replacement frequency depends on environmental humidity and usage conditions. In general, in a controlled laboratory environment, the desiccant may last several weeks to several months. Some advanced models use regenerative or automatic dehumidification systems, which reduce or eliminate the need for frequent manual replacement.

What is the difference between a dry cabinet and a moisture-proof box?

A dry cabinet is typically a larger storage system designed for long-term humidity control and often uses electronic dehumidification systems. A moisture-proof box for FTIR is usually more compact and is specifically designed to protect sensitive spectroscopy equipment or samples.
In short:

• Dry cabinet = general large-scale humidity control storage
• Moisture-proof box = targeted protection for precision instruments like FTIR systems

Does it work during power failure?

If the system uses passive desiccant materials, it can continue to provide moisture protection without electricity. For electronic humidity control models, moisture protection may gradually decrease during a power outage. However, most designs include sealed structures and backup moisture-absorbing materials to maintain short-term protection during interruptions.
