2.7.10 Screens
The screens prevent fluff, threads, etc. carried by the fabric from entering the air
circulation system. The screens are located on the suction duct. Depending on the
type and design, the machine may be equipped with fixed base screens which can
be removed after opening the service doors or with auxiliary screens which can be
removed during the machine operation. To ensure efficiency of the machine, lint
filters should be inspected and cleaned in every shift at least once. It gives efficient
cleaning of these filters if cleaned using brush or vacuum cleaners (Fig. 49).
2.7.11 Type of Radiators
Circulating Oil/Steam Heating
The circulating oil heating system supplies air heaters with heat transfer oil. The
ambient air is heated to treatment temperature by the air heaters, whereby the heat
transfer oil cools down.
The oil is then returned to a heating circuit in a closed-circuit loop where it
is heated again. It is then pumped to the air heaters once again. The temperature
regulator drives the control valve which varies the heat transfer oil supply until the
preset temperature is reached (Fig. 50).
