A Nyle Heat Recovery Venting System (HRV) was installed on this
kiln in the Northeast.
Seven HRVs were recently installed on existing kilns in the Northeast
as well.
that their Heat Recovery Vents, or HRV, as it’s typically
referred to, can become a valuable addition to any kiln.
The vent utilizes the heat being vented from the kiln to
warm the incoming air minimizing the need for “reheating,”
reducing the overall fuel consumption and increasing
overall production quality. “We have seen our customers
save up to 80 percent of lost heat when switching
to our HRVs,” said Howard.
This past year, Nyle also rolled out a new industry-leading
kiln control. “Our new NDK-R puts an advanced controller
into the hands of the kiln operator, allowing them
complete control over their kiln schedules and product

Dry Kilns and creator of the new control. “This new control
system boasts the same features Nyle had had in
their controls for years while adding advanced features
such as: Electronic Wet-Bulb/Dry-Bulb, Mobile/Webbased
controls, and advanced scheduling system.” The
“R” in the controls name stands for “retrofit,” meaning
their control will work with any kiln regardless of the
manufacturer.
A number of Nyle’s customers have already seen
success with this updated control system. The NDK-R
control utilizes five control modes: DH, Conventional,
Hybrid, Heat Treating, and Dump Cycle mode. Viljoen
explained, “The different modes allow for the operator to
better suit their drying process to the particular species
of wood that they are drying. Hybrid mode has proved to
be an ideal mode for faster drying Hardwoods because
