Full Description

This article presents a climate control strategy for the preservation of collections, specially designed for and installed at the Amazonian ethnographic storage of the Museu Paraense Emílio Goeldi in Belém, Brazil. Technologically simple and low cost to install, the system is robust and economical when in operation. It aims to maintain the relative humidity below 60% to prevent the collection from fungal and bacterial attacks while allowing the temperature to vary with the outside climate. The system has maintained the designed preservation environment for the last five years with minimum energy consumption and low maintenance costs. The strategy has also proven its robustness to maintain the conservation environment even during extended power outages common in the region.
