The Maxi One constant volume humidity generator is an automatic, positive pressure humidity control device for museum displays or other spatial volumes up to 500 m³. The Maxi One offers a unique scalable output: a single unit in remote location can reliably maintain stable humidity levels in one very large or multiple smaller showcases. The Maxi One can provide up to 500 m³ of pollution free, clean, humidity controlled air per day. Your desired climate can be kept constant to within 3% RH.

Operating principles

One or more air pumps are used to provide filtered air at the delivery pressure and flow required for the application. In the Maxi One the air is passed through a cooled water bath to control humidity levels, and distributed to the enclosures via flexible tubing.

The Maxi One uses small diameter hoses to distribute conditioned air to showcases up to 80 meters away, allowing great freedom for architectural design and easy retrofitting when renovating. Air is supplied as a positive pressure feed only, there is no return flow.

Displaced air from the case is exhausted through naturally occurring leakage, preventing ingress of dust or pollutants.

For the delivery hose, various diameters can be used, depending on the hose routing and the application. Built-in rotameters provide exact control for each air performance.

The system consists of 3 modules: main module, water container and air pump(s). If the system is connected to a domestic water supply, it will function fully automatically, needing minimal maintenance.

Installation

The Maxi One units can be located up to 150 meters from the exhibition, in a machine room, janitorial closet, or any space with adequate room, ventilation, water supply (optional), drain (optional), and power connections. The unit will operate in an environmental range of 15 to 30 degrees centigrade and at higher humidities, but optimum performance will be found at lower ambient temperatures.

The unit comes complete with a high-quality temperature and humidity sensor which must be located in the gallery. Sensors may be wall mounted, or optionally placed in a “representative” showcase. Environmental data is returned to the control panel on the unit by cable.

Remote Monitoring

Existing museum Wi-Fi networks may be used to connect the units to the internet, and rhmonitoring. com is accessible through any web connectable device. Monitoring can be done from any location.

www.rhmonitoring.com can be used to report on current relative humidity and temperature conditions and historical data, as well as changing some operating parameters. Sensor history graphs may be generated, and notifications and alarms can be automatically sent by email as required.
