HENCH IR Desiccator: Precise Humidity Control, Consumable-Free, Long-Term Protection for FTIR Spectrometers
8月 28, 2026
FTIR spectrometers are widely used in university research, pharmaceutical quality control, chemical analysis and material testing. However, sensitive internal components, including optical lenses and detectors, can be affected by prolonged exposure to humid air. Excessive moisture may cause lens mildew, baseline drift and measurement errors, affecting spectral accuracy and instrument service life.
Designed for Thermo Fisher IS 10, IS 20 and APEX FTIR spectrometers, the HENCH dedicated IR desiccator provides a controlled low-humidity storage environment without the need for disposable desiccants. It combines precise humidity control, consumable-free operation, low energy consumption and structural sealing to provide continuous moisture protection for FTIR instruments during operation and standby periods.
For laboratories looking for different types of FTIR moisture-proof boxes and desiccant storage solutions, HENCH provides dedicated equipment designed around the environmental protection requirements of precision infrared instruments.
Accurate Intelligent Humidity Control for FTIR Instruments
The HENCH FTIR desiccator uses a high-precision humidity sensing module and microcomputer-controlled system to maintain the selected humidity level. The humidity can be adjusted from 18% to 50%RH, with a control accuracy of ±3%RH.
The system continuously monitors the humidity inside the cabinet. When humidity rises above the preset level, the dehumidification system starts automatically. Once the target humidity is reached, the unit enters an intelligent standby mode to reduce unnecessary energy consumption.
This automatic cycle helps maintain a stable low-humidity environment rather than relying on manual adjustment. For FTIR spectrometers, controlled storage conditions help reduce moisture-related risks to optical components and support stable instrument performance during extended storage.
Consumable-Free Dehumidification for Lower Maintenance
Conventional moisture-proof cabinets may rely on disposable desiccants that require regular inspection, replacement and handling. The HENCH IR desiccator uses a dehumidification system combining a regenerable molecular membrane with solid-electrolyte dehumidification technology.
Moisture absorption, regeneration and moisture discharge are completed automatically during operation. No disposable desiccant replacement is required.
This design reduces routine maintenance work and eliminates the ongoing handling of conventional moisture-absorbing consumables. The cabinet can operate continuously for long periods with minimal manual intervention, making it suitable for laboratories where FTIR instruments may remain unused during weekends, holidays or extended standby periods.
Low Energy Consumption for Continuous Operation
The HENCH FTIR desiccator is designed for continuous low-energy operation. Its optimized electrical and dehumidification structure keeps daily power consumption at approximately 0.3 kWh.
Low energy consumption helps control the operating cost of long-term instrument storage. The unit also operates with low noise during its working cycle, minimizing disturbance in laboratory environments.
A power-failure humidity-locking function further improves protection during unexpected outages. When the power supply is interrupted, the cabinet is designed to limit rapid changes in internal humidity and reduce the risk of moisture exposure to stored equipment.
Reinforced Cabinet with Sealing Protection
The cabinet body is constructed from 1.5 mm cold-rolled steel plate with an anti-static and flame-retardant spray coating. A 5 mm load-bearing plate is installed at the bottom to provide additional structural strength and resistance to deformation under load.
The cabinet seams are sealed with curing adhesive, while highly elastic composite rubber strips are used around the door to improve closure and reduce the entry of external dust and moisture.
The internal wiring adopts a concealed protective layout, with an additional PCB protection board to help protect electrical components and improve overall operating stability.
These structural features work together to create a more stable storage environment for FTIR spectrometers and other moisture-sensitive laboratory equipment.
Dedicated Compatibility with Thermo Fisher FTIR Spectrometers
The HENCH FTIR-specific desiccator is designed to accommodate mainstream Thermo Fisher FTIR models, including:
- Thermo Fisher IS 10
- Thermo Fisher IS 20
- Thermo Fisher APEX
The dedicated cabinet design allows full-unit protection without requiring disassembly of the FTIR spectrometer. This makes the solution suitable for laboratories that need to protect installed instruments during periods of non-use or long-term storage.
For other instrument models or specific cabinet requirements, compatibility should be confirmed according to the instrument dimensions and configuration.
Suitable for Laboratories and Precision Testing Environments
The HENCH IR desiccator is designed for environments where humidity control is important for protecting precision analytical instruments.
代表的な用途は以下の通り：
- University and research laboratories
- Pharmaceutical quality control laboratories
- Chemical testing facilities
- New material research centers
- Industrial analytical laboratories
- FTIR instrument storage areas
By maintaining a controlled low-humidity environment, the cabinet helps reduce moisture-related risks during periods when FTIR instruments are not in active use.

Why Use an FTIR Moisture-Proof Cabinet?
FTIR instruments contain optical and electronic components that can be affected by unsuitable storage conditions. Maintaining a controlled humidity environment can help reduce the risk of moisture-related degradation during extended periods of standby.
A dedicated FTIR moisture-proof cabinet provides several advantages:
- Controlled humidity instead of passive moisture absorption
- Continuous automatic dehumidification
- No routine replacement of disposable desiccants
- Reduced maintenance requirements
- Low energy consumption for long-term operation
- Sealed protection against external dust and moisture
- Dedicated compatibility with selected FTIR spectrometer models
If your laboratory requires a different cabinet configuration or a broader range of FTIR moisture-proof boxes, the HENCH product range can be reviewed according to instrument type, cabinet capacity and storage requirements.
