In the past 40 years, Nyle has built thousands of kilns, installed around the world literally on every continent except Antarctica. Throughout that time we have developed deep experience in drying all kinds of lumber. We continue to use that experience to make our kilns longer lasting and easier to use than any in the industry. Our kilns and support are far out in front in kiln drying technology!
Whether you are thinking about starting a kiln operation or an expansion, for the best in conventional kilns, call on Nyle. We can help you review how to dry different species and thicknesses, how to handle the lumber, how to lay-out the operation for maximum efficiency, what system to use for most economical and flexible drying, etc.
Whether you are looking for a complete, turn-key dry kiln system of for specific components, you have come to the right address. Nyle is well known for providing custom solutions for our customers. We are not looking sell you as much as possible, we are looking to sell you exactly what you need and to do an excellent job and become your dry kiln supplier for years to come.
The coils are a key component to get right. Over the years, Nyle has worked exclusively with a quality coil provider to develop coils that last. Specifically for the lumber industry.
The coils are supplied in two grades: Better and Best. Both types work equally well but the difference is in how the coils are made and how long they last. The Better coils are copper tubes/aluminum fins with aluminum casing and the whole coil is coated with a special corrosion resistant material, greatly extending the life cycle of the coil. We were the first and may still be the only company to use coated coils in kilns. The Best coils are stainless steel tubes, headers and casing with aluminum fins. These are virtually permanent coils.
Indirect Gas Fired Kilns
The price for natural gas has come down tremendously and is expected to stay that way for a long time. Competition has driven the price of compressed natural gas and propane down significantly too. That means that gas has become a low cost alternative to heat your kiln. In some areas with high electric rates even more economical than our dehumidification kilns. That’s why we have developed a range of indirect, gas fired kilns. What is the most economical kiln will depend on the price of natural gas and electric at your location.
Our kilns are the best insulated kilns in the industry which reduces heat loss and therefore reduces operating costs significantly. We provide both fork lift loaded and track style chambers. So give us a call to discuss your needs, decades of experience will assure you get the right kiln for the right price.
Direct fired versus indirect
We get this question a lot: “Should I use direct fired or indirect fired, what exactly is the difference?” Nyle’s indirect fired kilns use a furnace and a heating coil. The gas flame is fully contained in the heating coil and heats it from the inside. The air is blown over the coil and gets heated that way. This is a safe way of doing it: There is no open flame and no exhaust in the kiln. Direct fired kilns on the other hand introduce outside air constantly into the kiln so it is difficult to accurately control the process and can damage lumber. They are a lower cost purchase because they don’t require the heating coils that indirect fired kilns do. The entire kiln relies on a screen ahead of the burner to catch any flying sawdust, shavings or scrap from passing through the fire and igniting the kiln. Screens can corrode and/or fail over time. This is why more and more insurance companies are having a real issue with this methodology and sometimes decline coverage.
Nyle uses indirect fired systems, even when they are a little more expensive to build, because they have a better safety record and much better quality control.
Nyle Chamber Design
The entire frame of a Nyle provided kiln is aluminum. The frame is erected on a slab, with a 12” by 12” stub wall. The complete frame is prefabricated and will not require any field welding. The frame of the kiln includes an all-aluminum fan truss that has the fans mounted on the truss at the factory. The door lintel is also part of the frame and all aluminum.
The walls are made with aluminum pans that hold the insulation with the best R-value of any board insulation. The wall pans attach to the aluminum columns. The pans are designed so that they will not hold water and will drain any condensation that might occur. The wall system is designed to minimize condensation and maximize insulation. The exterior typically is patterned aluminum.
The roof consists of an aluminum interior, designed to prevent water accumulation. On the interior will be the insulation. The exterior of the roof is aluminum roofing which will be mounted in such a way to minimize any possibility of leakage. The roof system will be supplied with all appropriate flashing and trim. The roof is typically pitched to the rear.
All the fan housings are welded into an aluminum truss that will extend the width of the kiln chamber. Panel, frame and baffles will be provided that will extend from the fan truss to the front and back edge of the lumber stacks.
Our conventional kilns can be gas fired, hot water or steam heated. Nyle provides both fork lift loaded and track style chambers. Call us to discuss your needs. Decades of experience will assure you get the right kiln for the right price.
