BULLETIN TO-610 HEAVY DUTY |
Grieve has designed and manufactured tunnel ovens for all types of processing.
These ovens have been designed for use with a wide range of existing conveyor
systems. Since 1949 we have been providing electric, gas and steam heated units
with operating temperatures from 150°F to 1200°F.
Tunnel Ovens from Grieve meet the requirements of National Fire Protection Association
Standard 86, Industrial Risk Insurers, Factory Mutual and OSHA standards. For
applications involving flammable solvents, the additional safety devices required
by the above organizations are included.
Tunnel Ovens are designed to include support points for your conveyor system.
Adjustable silhouette dampers are provided on the oven end openings to minimize
heat loss.
Each oven is designed for the specific application and can include multiple
heat zones and a cooling zone. Units can be provided in sections for easy installation
and matting with existing conveyor system.
Our experienced engineers will work closely with you to develop a tunnel oven
to readily accept your conveyor system. Every unit is completely assembled and
tested prior to shipment.

Tunnel oven width is selected to accommodate the parts and conveyor system. The speed of the conveyor system and the dwell time determine tunnel oven length.
Heat zone length is the product of the conveyor speed and dwell time. To estimate the length of tunnel oven required, insert your process information in the relationship below.
To the heat zone length calculated, approximately 1 foot must be added for insulation and silhouette dampers at each end of the oven. Equipment width will be approximately 2 feet wider than tunnel work space width to accommodate insulation, duct work and control enclosure.
