Museum Display Case Microclimate Generator

Configuration Overview

Positive-Pressure Humidity Control supplies conditioned and purified air to wall cases, flat cases, freestanding cases, central cases, niche cases and large showcases that require continuous humidity regulation and clean airflow.

Dehumidification, humidification, purification and sterilization are configured around case volume, airtightness and project requirements. The range covers 2 m³ to 2,000 m³ and supports single cases or linked multi-case systems.

Key Functions

Positive-Pressure Humidity Control

Conditioned air is supplied under positive pressure. Depending on model, dehumidification uses a positive-pressure system or vapor-pressure balancing, combined with wet-media humidification.

Air Purification

Integrated or external purification can target formic acid, acetic acid, formaldehyde, VOCs and microorganisms.

Continuous Clean Airflow

Continuous airflow removes off-gassing from objects and reduces ingress of external pollutants.

Multi-Showcase Control

Large systems can serve one or multiple linked showcases, with independent humidity control where configured.

Remote Monitoring

Wireless monitoring, real-time data storage and touchscreen control are available for large systems.

Application Range

Wall display cases
Flat, freestanding, central and niche cases
Large display cases and linked multi-case systems
Collection-store cabinets
Luxury collection cabinets and compact premium collection spaces

Configuration Overview

Internal-Circulation Humidity Control is intended for small and medium freestanding display cases up to 12 m³. A fan draws case air through the main unit, sensors measure humidity, and conditioned air returns to the case in a continuous loop.

Working Principle

The aerodynamic fan draws showcase air into the unit. Temperature and humidity sensors send measurements to the controller, which regulates the internal air humidity before returning the treated air to the showcase.

Key Functions

Continuous Humidity Control

Provides uninterrupted, gentle control without abrupt change, within a 1% set range.

Internal Air Circulation

Continuous circulation removes gases released by collection objects.

Compact Installation

The compact main unit can be installed at the bottom or top of the showcase.

Wireless Monitoring & Data Storage

Two-way wireless monitoring and data storage support environment management.

Positive-Pressure & Filtration Options

A check valve supports positive-pressure operation; air filtration can be configured.

External Device Control

Control outlets support automatic water supply and external humidification or dehumidification devices.
