Side-Loading Kilns
Quality Lumber Drying For Specialty Products
Wellons’ side-loading kilns are designed to provide the ultimate flexibility for drying smaller load sizes. Side-loading kilns are ideal for small drying facilities with large variations in products and long drying schedules.

Heat Media Options
- Indirect Heat Systems
Wellons Indirect Heating Systems include Steam, Thermal Oil, or Hot Water as the heat medium. The heating systems are divided into stations and zones within the kiln for precise lumber drying.
Steam Heat
The steam heating system receives steam into a supply header from a boiler system which branches into several controlled zones. Each zone is controlled by either a pneumatic or electric valve which controls the flow rate of steam to each coil bank. Each coil bank is individually trapped and drains to a condensate return system. Humidity is vented through automatically controlled vents. Wellons designs systems for high pressure or low pressure steam depending on the drying application.
Thermal Oil & Hot Water
Thermal oil or hot water is pumped from the respective supply via a Primary Loop which sends and receives the fluid to and from the system. The fluid is directed to a header at each individual chamber where 2-way control valves adjust the fluid rate to the coil banks. Each valve and coil bank make up a zone within the system. The coil banks are fabricated of continually-welded, serpentine coils (fin pipe). The fluid is returned to the pumping system to reheat the fluid and return it back to the system.
Heating Coils
Overhead heating coils are standard equipment in side-loading kilns. For larger capacity kilns, hinged, swing-out center coils can be provided.
Wellons manufactures their own standard and high heat release coil banks. Many options of fin pipe are available based on heating requirements of the customer, including:
33 wraps per foot, Sch 40 2” pipe
48 wraps per foot, Sch 40 2” pipe
60 wraps per foot, Sch 40 2” pipe
All Aluminum/Stainless Steel fin pipe
- Direct-Fired Heat Systems
Direct-Fired systems circulate hot gases throughout the kiln utilizing an overhead supply and return ducting system. Direct-Fired heating systems receive hot gases from a supply burner. The gases are directed through overhead supply ductwork into the kiln and distributed using slide-gates along the length of the overhead plenum ducting. Excess gases are directed through return ducting into the recirculating fan. Heat supply options include Direct-Fired Biomass, Natural Gas, or Propane.
