Description
The TH-SSC-DL-800-RX combines a ductless filtered-storage platform with a custom sterile-storage control package. The cabinet is designed to maintain a monitored, positive-pressure environment for protected storage of compatible sterile medical supplies, packaged instruments, pharmaceutical materials and clinical equipment.
The cabinet’s primary operating mode is self-contained and ductless. Internal air is circulated through configurable filtration, monitored by the cabinet control system and returned to the storage chamber. Where the facility requires integration with its environmental system, the included retransmit kit provides a controlled connection to an approved ceiling-duct or return-air port.
The underlying cabinet platform supports an approximately 800-liter interior, high-rate internal air circulation, touchscreen controls, RS485 and Modbus communication, filter monitoring, intelligent locking and configurable activated-carbon or HEPA filtration. The related manufacturer brochure also identifies ductless filtration, VOC detection, internal circulation, an energy-efficient fan and mobile cabinet construction.
The sterile-storage customization incorporates the required temperature, humidity, positive-pressure, HEPA, UV-C, digital-monitoring and retransmit functions described in the project parameter schedule.

Ductless Filtration System
The cabinet is configured to operate without a permanent exhaust duct.
The filtration system may include:
- H14 HEPA filtration
- Activated-carbon filtration
- VOC filtration
- Acidic-gas filtration
- Formaldehyde filtration
- Multipurpose chemical-gas filtration
- Primary particulate prefilter
- HEPA pressure-loss monitoring
- Custom filter combinations based on the storage application
Final filter selection must be identified in the technical submittal and matched to the intended stored materials.
Sterile-Storage Environmental Controls
The custom sterile-storage control package shall include:
- Temperature monitoring and active control
- Relative-humidity monitoring and active control
- Positive-pressure monitoring
- Digital pressure display
- High and low environmental alarms
- HEPA-filtered air circulation
- Integral humidification or approved humidity-control system
- Refillable reservoir where steam humidification is selected
- Programmable operating controls
- Operating-status indicators
- Data output for facility monitoring
Performance targets must be confirmed during factory testing and on-site commissioning.
UV-C Supplemental Disinfection System
The cabinet shall include an enclosed UV-C system comprising:
- Recessed UV-C lamps
- Independent UV-C control
- Programmable cycle timer
- Visible operating indicator
- Door-position safety interlock
- Automatic lamp shutdown when the access door is opened
- Warning labels
- Lamp-life monitoring or replacement schedule
The UV-C system is a supplemental surface-disinfection feature. It does not replace validated cleaning, sterilization or instrument-reprocessing procedures.
Smart Monitoring and Access Control
The cabinet control system supports:
- Touchscreen display
- Temperature and humidity display
- Pressure display
- Fan operating status
- Filter-service-life monitoring
- Filter identification
- Total runtime
- Door-open alarm
- Fan-failure alarm
- Environmental alarm conditions
- Automatic fault diagnosis
- Fault-code and text display
- RFID access
- Password access
- Remote-unlock capability
- RS485 communication
- Modbus communication
- BMS integration
Retransmit Kit
The retransmit kit permits the cabinet to remain primarily ductless while providing an optional controlled interface with the healthcare facility’s main environmental system.
The proposed retransmit package includes:
- Cabinet-side return-air connection
- Ceiling-duct transition
- Flexible connection section
- Isolation or balancing control
- Backflow-control provision
- Condensation-management provision
- Supporting brackets and hardware
- Plug-and-play electrical or control interface
- Installation instructions
- As-installed connection documentation
The kit is intended to return a controlled portion of airflow and moisture to an approved hospital ceiling-duct or return-air connection. The facility’s engineering department must approve final duct size, airflow balance, connection location and building-management-system interface.
