The PMCG humidity generator represents an innovative solution for managing humidity levels within museum-quality display cases. Utilizing cutting-edge solid-state technology, PMCG units distinguish themselves from other alternatives by eliminating the need for filling or emptying reservoirs. Once the system is configured, humidity levels within the display case can be effectively regulated for extended periods without the requirement for condensate removal, water level checks, additions, or any other routine maintenance tasks. This design ensures a hassle-free and long-term humidity control solution for preservation needs in museum environments.
PMCG units are available in two versatile modes: DD (dehumidifying only) and DH (dehumidifying and humidifying). This flexibility allows users to tailor the functionality of the PMCG system to their specific requirements, providing a customized solution for both dehumidification and humidity control needs.
Under condition that showcase is well sealed, PMCG 2 is powerful enough for cases up to 2 m3 for DD version and 1m3 for DH version.
For well-sealed cases, PMCG 4 is good up to 4m3 case in DD version and up to 2 m3 as DH version.
In general, PMCG functions most effectively as a dehumidifying machine. In this mode, PMCG 2 and 4 can maintain the humidity levels within museum showcase within the range of 20-25%, or even well below 20% for smaller cases.

MASTER/SLAVE CONFIGURATION
When it is necessary to control humidity in a single large or leaky showcase, multiple units may be connected in a master/slave configuration. The master unit can be connected to a remote monitoring system as normal, and up to five slave units can provide extra control capacity to achieve the desired conditions.
