Further development of the aerodynamics for optimized, uniform air velocities in the dryer. The result is the UNI-VENT system. Dryers of all types can now be supplied in the MH 2000 AIR version. The higher air velocity in the chambers allows up to 40% faster drying. Set-up of the first "whisper" dry kiln of the MAHILD MH 2000 LOW NOISE series. Extremely low noise emission and high thermal insulation range characterize this series.
The MM8000 computer control with industrial hardware and software makes it possible for the first time to make program adjustments remotely.
The second generation of TMT kilns for the temperature treatment of wood is introduced in Europe and South America. The plants can be operated without boiler plants. New generation of ultra-high temperature chambers type MH 2000 UHT ST enables significant energy savings, even faster drying and extremely low maintenance intervals. New drying process for impregnated wood is introduced to the market.

A revolutionary new welding system for piping is introduced in the production plant, which can meet all standards (BS, ANSI, DIN, ISO, etc.). Installation of welding robots of the latest generation for the production of heating coils.
ADC drying programs based on real-time weight measurement of the drying charge are developed
The new Mahild LUVO technology allows the use of low temperature hot water (60-75°C) from exhaust heat of thermal power plants and reaches return temperatures of up to 40°C.
Adapted to each customer, each kiln and each Species, the Multi-Hum estimates the moiture content during the entire drying process. Using research performed by our own wood technologies engineering team, we were able to develop a formula that uses the current conditions in the kiln to determine a very accurate moisture measurement, eliminating the need for wired probes or any other type of direct measuring of moisture.
The PROZONE wood moisture measuring device was successfully used in the CONTRAFLOW kiln for the first time.
