Museum CollectionEnvironmental Control Cabinets

Active Humidity Control & Monitoring is designed for museums, archives, and professional collections requiring long-term humidity-controlled storage, environmental monitoring, and data management. The active control system automatically dehumidifies when cabinet relative humidity rises above the setpoint and humidifies when it falls below the setpoint, reducing risks associated with excessive moisture, dryness, and environmental fluctuation.

The water-free or low-maintenance design reduces routine filling and drainage. Temperature and humidity monitoring, data logging, and network connectivity support continuous management of the cabinet environment. Cabinet dimensions, internal layout, and monitoring modules can be configured around collection size, material, quantity, and storage method.

Adjustable Shelf Cabinet

For three-dimensional objects and collections requiring adjustable vertical clearance, including bronzes, ceramics, lacquerware, stone, jade, paintings, and other shelved objects. A standard arrangement can include five height-adjustable shelves.

Drawer Cabinet

For flat, rolled, classified, or layered storage of coins, precious-metal objects, works on paper, books, photographs, correspondence, textiles, and related collections. Drawer count and internal dimensions are project-configurable.

The rear-mounted humidity-control module integrates humidification and dehumidification under automatic microprocessor control. Its modular, detachable design does not occupy the primary storage area. The selected configuration uses a fanless motor design and a flame-retardant PPS enclosure rated to 230°C. Operating characteristics and design-life criteria are confirmed in the project technical proposal.

The cabinet uses cold-rolled steel sheet at least 1.0 mm thick and an overlapping welded structure to improve strength and airtightness. Doors use high-strength tempered glass at least 5 mm thick with magnetic automatic sealing. Reinforced construction reduces long-term load deformation that could impair sealing. A flush handle minimizes projection into circulation routes. Conservation-grade acid-free, formaldehyde-free powder coating provides scratch resistance, ageing resistance, and long-term surface stability.

When to Select an Adjustable Shelf Cabinet

More suitable for:

• Three-dimensional cultural-heritage objects;
• Collections of different heights and volumes;
• Applications requiring flexible shelf-spacing adjustment;
• Applications requiring higher load capacity per shelf;
• Bronzes, ceramics, stone objects, jade objects, and similar collections.

When to Select a Drawer Cabinet

More suitable for:

• Paper documents;
• Paintings and calligraphy;
• Books;
• Photographs;
• Coins;
• Textiles;
• Collections requiring flat, rolled, or classified storage.

Optional features include a local touchscreen display, out-of-range temperature and humidity alarms, door-status records, historical trend review, and data export. A local network or Wi-Fi connection can support central review of live temperature and humidity, setpoints, and alarm status across multiple cabinets.

RS485, RS232, or RJ45 communication interfaces can be integrated by project. Where connection to an institution’s existing collection, equipment, or asset-management system is required, the interface scope and data fields are defined in the technical proposal.

Active Climate Control & Air Purification is designed for museums, archives, and specialist collections requiring continuous control of temperature, relative humidity, and cabinet air quality. Refrigeration, heating, dehumidification, humidification, and purification modules actively regulate the internal environment. Temperature and humidity settings are managed through a touchscreen and programmable PLC.

Cabinet dimensions, door arrangement, internal storage format, and security options can be configured around collection dimensions, quantity, access practice, and site conditions.

Adjustable Shelf Layout

For three-dimensional objects and collections requiring adjustable shelf spacing.

Drawer Layout

For flat, classified, or compartmentalized storage of paper, organic, metal, and composite-material collections.

Cart / Trolley Layout

For bulk handling, whole-load movement, or larger collection objects. Trolley size, quantity, and clear internal volume are configured by project.

Door arrangements include double-door, single-door, and side-opening forms. Internal layouts include all-shelf, all-drawer, trolley, or project-specific structures. An electronic combination lock is optional.

The system combines refrigeration, PTC heating, molecular-sieve dehumidification, molecular-air humidification, purification, monitoring, touchscreen display, and PLC control.

The cabinet interior and exterior use stainless steel. Environmentally considerate polyurethane foam provides thermal insulation and flame resistance to improve temperature stability and reduce energy demand.

The refrigeration, heating, dehumidification, and humidification subsystems are coordinated by a central controller, with temperature, relative humidity, operating status, and alarms shown at the touchscreen interface. Temperature and humidity limits, alarm delays, door alarms, and historical records can be configured for the project.

Modular construction supports routine inspection and servicing. Final temperature and humidity control range, stability, noise, electrical load, and acceptance method are confirmed against cabinet volume, collection heat load, site conditions, and project acceptance criteria.

Airtight Passive Humidity Control is a low-energy storage configuration for museums, archives, and professional collections requiring stable long-term conditions. A highly airtight cabinet and passive humidity-control modules regulate relative humidity without continuous electrical power.

Target humidity values can be selected for different collection needs. Wireless temperature and humidity monitoring, remote data management, and low-oxygen control can be added as project options.

The combination of airtight construction and passive humidity buffering reduces the influence of external RH fluctuation, particulate ingress, pests, and mold. It can help mitigate hardening, cracking, deformation, embrittlement, corrosion, and ageing associated with unsuitable moisture conditions.

Humidity-control modules are selected according to target RH and cabinet volume. Relative humidity can be selected in staged values across 10%RH–90%RH. The passive media require no continuous electricity, manual water filling, or drainage.

The design target is an air-exchange rate of N≤0.02 d⁻¹. Project documentation confirms the applicable standard, scope and test basis.

Optional low-oxygen control may be integrated with the airtight enclosure. The final control method, standard scope and acceptance criteria are confirmed for each project.

The Low-Humidity Storage Cabinet is intended for storage conditions where continuous dehumidification is the primary requirement. Humidity sensing, microprocessor control, and a dehumidification module work together to maintain a stable low-relative-humidity environment inside the cabinet.

Active temperature control is not a standard function of this configuration. Target humidity, cabinet construction, monitoring method, and acceptance criteria are confirmed against collection material, condition, access frequency, and site environment.
