CTT 40 / CTT 70 6. Functional description » This functional description is addressed to the operators of the equipment. This functional description assumes general familiarity with drying equipment. 64.10-0214GB10 04/02 It should be verified that the operators do indeed have the appropriate skills.
CTT 40 / CTT 70 6.1. General Information The dehumidified air dryers were developed for drying plastic granules. Due to their compact construction, they can be employed next to the processing machine (drying hopper on the processing machine) or with one or more drying hoppers as a movable facility (compact facility). The dryers work according to the dehumidified air principle, i.e., the air is not only heated but also dehumidified before it flows through the drying hopper.
CTT 40 / CTT 70 All function sequences are fully automatic. The dryer is equipped with two drying cells. One drying cell is part of the drying cycle; the other drying cell is regenerated simultaneously. 64.10-0214GB10 04/02 Part of the dehumidified air is used for regenerating the moist drying cell. At the beginning of regeneration, it is heated by the regeneration heater. After the end of the heating period, the drying cell is cooled off by means of dehumidified air.
CTT 40 / CTT 70 A digital display of the current dew point temperature can be supplied as additional equipment. As an option, a timer clock can be supplied which switches the dryer on or off at preselected times. F Read the operating manual of the timer clock. 1 2 8 64.
CTT 40 / CTT 70 6.2. Drying Hopper (Optional) The material is dried in the drying hopper. The dehumidified air is conducted through the material in the drying hopper and takes up moisture. Drying hoppers must have the appropriate dimensions for their specific use so that the desired final moisture content is reached. When refilling a drying hopper, the material must first be dried completely before material can be taken out for the first time.
CTT 40 / CTT 70 6.2.1. Hopper Heater Each drying hopper has its own hopper heater. The temperature of the dehumidified air is adjusted by means of the thermo regulator. The setting range is from +60 - +180 °C (+140 - +356 °F). The current temperature can be read off the digital display (= actual value). F The thermo regulator is factory-programmed. Nevertheless, you have to set specific values which are dependent on the processed material.
CTT 40 / CTT 70 6.3. Connection to a Pneumatic Conveying System (Optional) Your drying facility works best in combination with a pneumatic conveying system. In this way, your drying hopper will always be supplied with sufficient material. The facility will only take as much material as is required by the processing machines. Therefore, the drying result will always be the same. Colortronic drying hoppers are equipped with a suitable flange for adding a Colortronic pneumatic conveyor.
CTT 40 / CTT 70 7. Transport, Assembly and Storage » This chapter is intended for all operating personnel of the equipment. Personnel using these instructions must be instructed in the regulations for the prevention of accidents, the operating conditions and safety regulations and their implementation. Ensure in each case that the operating personnel are sufficiently informed.
CTT 40 / CTT 70 7.1. Tansport and Packing » F Please ensure adequate carrying capacity of the lifting equipment. Note that the dryer system is top-heavy. Risc of toppling! The machine must not be tilted or laid on its side. The equipment pass a rigorous operating test in the factory and are packed carefully to avoid transport damage. Please check packing on delivery for transport damage. The inlet and discharge flanges are sealed with plugs, so that no dirt can enter during transport.
CTT 40 / CTT 70 7.2. Assembly » Please ensure adequate carrying capacity of the lifting equipment. Check the carrying capacity of the point of installation, particularly if installed on a platform. The place selected for installation should be as free of vibrations as possible. The main switch must be freely accessible. Ground the equipment against electrostatic charging. F The machine must not be tilted or laid on its side.
CTT 40 / CTT 70 8. Assembly instructions » These installation instructions are intended for persons with skills in electrical and mechanical areas due to their training, experience and received instructions. Personnel using these installation instructions must be instructed in the regulations for the prevention of accidents, the operating conditions and safety regulations and their implementation. Ensure in each case that the personnel are informed.
CTT 40 / CTT 70 8.1. Installation of the exhauster fan for regeneration of exhaust air When plastics are being dried that release harmful gases during the drying process, care must be taken that the regeneration exhaust air is disposed of in an environmentally sound way. At the same time the throughput of the regeneration blower must not be altered. It should be noted when assembling a disposal system (e.g. an exhauster system) that the regeneration exhaust air is very humid.
CTT 40 / CTT 70 8.3. Electrical Connection » Observe the rules of the local electricity board. Check that the supply voltage and the power frequency are in accordance with the data on the name plate of the device. The electrical connection may only be carried through or assigned by Colortronic service staff or by qualified staff authorized by Colortronic. Other persons are not permitted to carry through the electrical connection. The main switch must be freely accessible.
CTT 40 / CTT 70 8.4. Connection of Return Air Cooler (Optional) F A return air cooler must be employed if the return air temperature is higher than +65 °C (149 °F). You can connect the return air cooler to a coolant circuit or to the water mains network.
