EZ-SEAL HEAT TUNNEL
MAIN COMPONENTS
CONVECTIVE (BR/SR Models)
The Convective style Heat Shrink Tunnel has the following main components:
1. Temperature Controller (1128) – The temperature controller monitors a thermocouple and
controls power to the heater elements to maintain the set temperature.
2. Thermocouple (1031) – The thermocouple monitors the temperature of the air in the tunnel.
3. Solid State Relay (1127 220VAC)/(1220 480VAC) – The Solid State Relay takes the signal
from the temperature controller and turns on and off to control the flow of electricity through
the heating elements.
4. Fan (1057) – The fan and its two blower wheels provide the forced air flow through the
tunnel. The lower wheel (3052) provides the re-circulating flow of hot air which shrinks the
film. The upper wheel (3072) provides a flow of air that keeps the control components cool
and cools the outer skin of the tunnel.
5. Heat Up/Cool Down Switch (1066) – This switch allows the operator to enable and disable
the heating elements to allow the tunnel to heat up or cool down.
6. Snap Switch (1089) – Bimetallic switch which controls the operation of the fan. Turns fan
on and off at about 120 degrees F.
7. Heating Elements (1042 220VAC)/(1221 & 1223 480VAC) – 3600-Watt resistive type
heating elements provided.
The fan and temperature controller operate on 220 Volts AC. If the tunnel is provided for a voltage other
than 220 VAC then a step down transformer is provided.
RADIANT (IR Models)
The Radiant style Heat Shrink Tunnel has the following main components:
1. Proportional Controller (1631) – The temperature controller, with an integral on/off switch,
monitors the amount of electrical current to the heating elements and turns on and off to
maintain the desired heat level.
2. Fan (1054) – The fan provides a flow of air that keeps the control components cool and cools
the outer skin of the tunnel.
3. Infrared Elements (1629) – 2500-Watt metallic type heating elements with reflector.
