Products inception dates back to 1938 when Emil
Tjernlund and his son Robert started designing and
manufacturing oil fired forced air furnaces. From this
start their product offering evolved into gas fired
furnaces and custom packaged roof top heating & cooling
equipment. In the mid 1950's our Auto Draft Inducers
were developed to eliminate draft problems associated
with short stacks on roof top units. Other people within
the heating industry soon saw the advantages of our
draft inducers and wholesale distribution of the Auto
Draft Inducers began in 1957.
Products was spun off as a separate company in 1973.
The original manufacturing facility had 10,000 ft2 and
12 employees. Since then we have expanded our facility
to 90,000 ft2 and have grown to over 75 employees. Our
engineering and manufacturing departments feature the
latest technology in 3D CAD design and CNC turret
presses and brakes.
Products is still owned and managed by Emil's
grandsons, Robert and Tom and Emil's great grandson Bob.
Over four generations our mission has been to provide
quality engineered and manufactured products that solve
exhaust, ventilation and heating/cooling problems.
Paramount to our success is providing the technical
support necessary so that our products are easy to
select and install. We are dedicated to serving your
special exhaust and ventilation needs.
