Diagram in the front panel with distribution of the elements similar to the real one.
- Stainless steel vertical tunnel of 1200 mm long of rectangular section (65 x 170 mm) and resistant to
corrosion.
- Rectangular central opening of 200 x 150 mm in the tunnel with two supports made of stainless steel to
hold the plates with the exchangers.
Elastic tunnel – fan coupling flange with clamp.
- Centrifugal fan, with a variable-speed drive; operating range: 0 – 10 m/s.
Two “J” type temperature sensors.
- Speed sensor to know the air speed, range: 0 – 15 m/s.
- Heating element with a diameter of 16 mm and 80 mm long (500 W) with control thermocouple.
Wattmeter to measure the power supplied by the heating elements.
- Included exchangers:
- Single tube exchanger: one exchangeable plate made of Teflon with flat surface with a central bore to ATENG 12901 detail
install the single tube heating element.

Included elements
- PVC of 16 mm approximately of diameter arranged in an equilateral triangle. The tubes are arranged
in six rows and there is a removable tube close to the center of each row. It can be replaced by the
heating element to measure the effects of the rows of adjacent tubes on the heat transfer rate of the
heating element.
