DBT 360, 370, 370S, 380, 390, 390S and 400 types are equipped with two towers with molecular sieves. The dehumidifying process is continuous and uninterrupted: while a tower is dehumidifying the other one is regenerating. PROCESS CYCLE. The air returning from the hopper will be aspirated by the process blower (SP) through the filter (F1) and the valve (SC). Then it will go through the pipe and conveyed into the drying cell (CE2) containing the molecular sieves which will dry the air. After that, air passing through tower A will be conveyed into the heating chamber (CR1) through the slide valve (VD1). Here air will be heated till it will reach the temperature set and will enter the hopper (HB) through the pipe (TE). In the hopper there is the material that has to be dehumidified and the hot and dry air will exit from the cone diffuser and flow upwards. The humidity contained in the material will be absorbed and the air, now humid, flows out from the upper side passing through the filter (F3). Air will begin its work cycle again after the filter (F1) and it will be recycled through the pipe. Air temperature at hopper’s force main will be set by means of the display placed on the front side of the control panel (refer to section 3.4 for this operation) and it will be measured by means of a drill (PT 100) placed at the hopper’s force main. REGENERATION CYCLE. When tower (CE2) is dehumidifying air, tower (CE1) is regenerating, i.e. it is giving away all humidity absorbed by the material. The regeneration cycle is divided into two parts: The regeneration blower (SR) will aspire air from the outer environment through the filter (F2) and after that, through the slide valve (VD2), will convey it into the drying cell (CE1) passing through the electrical resistances (R2) that at this stage are activated. The absorbing material (molecular sieves), passed through by the airflow at a high temperature, will give away the humidity absorbed during the previous cycle. The air, now saturated with humidity, will be conveyed through the slide valve (VD1) into the pipe and then into the outer environment. After the first heating phase of the molecular sieves, the resistance (R1) shall be deactivated and the cooling phase will begin. The regeneration blower (SR) will stop and remain deactivated till the process will be finished. In the discharge pipes for regeneration air there is a drill installed: tower shifting, usually operated by the electronic board according to the time set, depends on the fact that the temperature measured by the drill should be lower than 70°C. This temperature value makes sure that the tower has been cooled down and can begin its dehumidifying process. The high insulation rate of the two drying cells, allows to save energy during the heating phase, and protects also the other inner components of the machinery from over heating episodes. In DBT 360 and 370 models the total time for regeneration cycle is 180 minutes (90 minutes for heating + 60 minutes for cooling + 30 minutes waiting time for towers to shift, the blower must not be activated). In DBT 380, 390 and 400 models the total time for regeneration cycle is 240 minutes (150 minutes for heating + 60 minutes for cooling + 30 minutes waiting time for towers to shift, the blower must not be activated)

In case of doubts, do not ever take initiatives and contact the Producer.

DANGER! MAINTENANCE OPERATIONS Before acting any maintenance operation, read carefully all instructions in the present manual and the electrical documents attached. In case of doubts, contact the Producer.

DANGER! During the mainenance activity, it’s recommended to NOT ever run more than one operation at a time, going to the next step only after verifying that the previous action has been completed successfully and safely.

DANGER! The inside of the reactor can be classified as a "confined area"; so, before to enter, analyze the air and, if necessary, wear antigas masks or, depending on the type of treated material, wear self-contained breathing apparatus.

18.1 CLEANING AIR FILTERS

This operation is both for the dehumidifying unit filter F1 and the hopper filter F2 • Turn the switch of the dehumidifying unit on ‘0’ in order to avoid a sudden start of the machinery; • Unfix the screws of the filter covers (F1 and F2) and pull the cartridge towards the outside; • Clean the cartridge by means of high-pressure air until it will be cleaned (this operation must not be carried out near the blower); • Replace the cartridge into the filter and fasten the screw of the cover. Pay attention to the seals: they must be closed well, so that there will be no air losses that will cause lower pressure values and dirty air passing through the pipes; • Switch on the mains and the power supply of the dehumidifying unit again. If the filter is broken, you must replace it with a new one. The above described operations must be carried out weekly , but, if the material treated is dusty, the filters shall be cleaned also two or three times a week .

18.2 CLEANING THE BATTERIES

Do following operations to clean the cooling batteries in a proper way: • Check that tension of the mains and that of the dehumidifying unit are switched off before doing maintenance operations; • Wait till the machinery cools down (1 hour); • Open the front panel by means of the proper key; • Remove the cooling water pipes; • Remove the sleeves from the radiator (see picture); • Open the batteries and pull out the radiator/s; remove the 4 screws fastening the battery to the bottom of the machinery (see picture); • Clean the flaps by using high-pressure air; • clean the inner pipes from encrustations; • Mount the radiator(s) again, close the battery, restore the hydraulic connections • Close the outer panels and switch on the mains and open the hydraulic supply..

18.3 CLEANING THE BLOWER FILTER

Do following operations to clean the net blower filter, placed at air force main: • Disconnect the power supply between the machinery and the mains and switch off the dehumidifying unit; • Remove the panels by means of a screwdriver; • Disconnect the air force main of the blower; • Check if the net filter is obstructed and clean it using high-pressure air (do not carry out this operation near the blower); • Insert the filter retina in the joint hub, fasten the screws and close all, restoring all parts as before.

18.4 CHECKING THE PIPES

Air conveying pipes must be checked each time losses of the dehumidifying unit efficiency and non proper pressure in the pipes will be detected. Follow safety regulations before carrying out any operation and disconnect the electric supply. Wait till the machinery cools down (1 hour).

18.5 CHECKING THE SIEVES CLOSING SPRINGS

The tower has a component inside whose property is to absorb air humidity. This material is composed of granules that fill the inner part of the tower. As time goes by and as air flows through the granules, it produces a continuous rubbing which modifies the characteristics of the granules themselves. For this reason we use compression springs that push onto the tower cover and hold the granules tight. The compression springs must be checked every six months in order to work properly. Do following operations: • Disconnect the mains between the mains and the dehumidifying unit by means of the line arrester and switch off the dehumidifying unit using the proper switch; • Wait till the machinery cools down (1 hour); • Open the panels of the machinery by means of a screwdriver; • Remove the hose clips and open the tower cover carefully; • You only need to fasten the bolts on the springs to get a higher compression of the granules; • Close the cover and the panels restoring all parts as before • WARNING: • Wear safety gloves before doing any maintenance operation during which operators come into contact with granules; • Do not fasten the compression springs too much, otherwise they may get worn out

18.6 CHECKING/REPLACING THE FUSES

Fuses play a very important role because they protect the whole electrical system from electrical over absorption. If a fuse gets burned, the origins that have caused the sudden change of tension in the electrical system must be found out before proceeding. The cause must be removed and then the fuse can be replaced. Follow the instructions given below: • Disconnect the power supply between the mains and the dehumidifying unit and switch off the dehumidifying unit; • Open the front panel of the dehumidifying unit by means of the proper key; • Remove the fuses and check if they are interrupted; • Replace the fuses with new ones, having the same dimensions and characteristics; • Close the fuse block after having replaced them and close the front panel of the dehumidifying unit.
