Large Dehumidification Dry Kiln Systems

HT Systems

More than thirty years ago, NYLE invented the high temperature dehumidification lumber drying system. Our patented XDH system, a breakthrough in dehumidification drying, constantly monitors and regulates the airflow within the dehumidifier. This for the first time enabled dehumidification kilns to operate at up to 160ºF (72ºC) and match the drying speeds of most conventional kilns as well as allowing easy pitch setting and sterilization, all this with greater energy efficiency than any other system in the world.

In the more than three decades since, NYLE has focused on constant improvement in technology to assure years or reliable and efficient operation. Our kilns come with reliability features such as corrosion resistant aluminum cabinets, dehumidification coils that are specially coated to withstand the acids and harsh atmosphere in a kiln, stainless steel cold coils and tubing, and many other features that make your system last longer and perform better are included in a Nyle system.

Hundreds of units have been sold. NYLE Systems save energy, reduce your capital and operating costs while making drying simple and allowing even inexperienced operators to produce the highest quality lumber and improve yields. All while running the most environmentally green system.

Systems so big they pull almost 20,000 pounds of water daily, but so efficient, your boards dry for only pennies per square foot, that’s the HT Series kilns from Nyle

HT kilns are made to order. Based on your needs, we select a base model and together with you, we specify fans, dehumidifier and vents to suit your lumber, your needs.
