Flexibility for our Customers

The Thermo Lignum® mobile WARMAIR system

Sometimes infested objects cannot or should not be moved; be it an altar, an organ, choir stalls, or any other large or heavy object in a fragile state. From a conservator’s point of view any movement of sensitive objects should be avoided. The heavier or bulkier an object is, the more likely it is that it will suffer during transport. This is where Thermo Lignum® comes in with their in-situ treatment.

The objects are enclosed within a custom-made insulated framework, using a special foil, into which humidified WARMAIR is passed. Inside this “tent” numerous temperature and humidity sensors are positioned. A continuous flow of data is received from the sensors, enabling the operator to accurately monitor and adjust accordingly, the RH and temperature within the enclosed atmosphere in order to recreate the same conditions as in our static or mobile chambers. All data are logged and recorded by a computer

Thermo Lignum has carried out in-situ treatments in various high-profile historic buildings. Both in 2004 and in 2010 we worked at the Aachen Dome near the Dutch-German border. The Dome in Aachen is a UNESCO World Heritage Site.
Our mobile units were deployed to Rome twice to battle acute Oligomerus ptilinoides infestations in the rennaisance church of Santa Maria dell'Anima as well as the Austrian Embassy in Vatican, the Holy See (Vatican City).
