TERMOGRAPHIC ANALYSES

In the field of energy saving, bays for frozen goods must pay maximum attention to the reduction of heat loss, in which the greater the loss, the greater the costs.

Thermographs are scientific devices that measure heat loss, allowing the immediate visualization of areas of loss and the amount of loss.

Campisa carries out thermographic analyses on request.

An example of thermographic analysis on the heat losses of a sectional door is shown in the image above, representing the top left quarter of the door taken with normal photography and with thermographic imaging. The thermography clearly shows the areas of greatest loss, represented by the colour blue which in the darkest point reaches a temperature of 13.5°C. Considerable loss can be seen along the upper and side gasket, and you can see how the leaf provides good insulation.

Depending on the location of the delta between internal and external temperatures it is possible to supply sectional doors with a thickness of 80mm, which are highly insulated, and apply special watertight perimeter gaskets, guaranteed by the door’s FIDELITY hydraulic lifting system.

The heat loss can sometimes be easily identifiable to the naked eye.
The photograph below clearly shows at a glance, the enormous losses of heat from the spring balance door which, if not well balanced, “floats” and remains always open by around 5 cm.

> First image – spring sectional door: if the springs (green arrow) are not loaded, opening it will be difficult (heavy). If the springs are loaded, closure to the ground will always be approximate, with large cracks (blue arrows) and substantial heat loss.
If the closure is with a geared motor, by sealing to the ground there is a risk of the cables slipping and breaking. The springs rust in refrigerated environments and leave traces of rust on the wall and the floor (red arrows).

> Second image – FIDELITY hydraulic sectional door: closure to the ground (blue arrow) is always perfect because the door does not have balance springs and offloads all its weight to the ground. The hydraulic motor (green arrow) is contained in a galvanized case situated above the door, not subject to rust.
The electro-hydraulic console (red arrow) is positioned at human height on the right (or left) of the door. In the case of the loading bay the console provides the hydraulic force for both the door and the loading ramp.
