Drying plastic granulate

The KKT dryer range for hygroscopic materials is designed for dry air volumes of 55, 75 and 100 m³/h. In addition, these auxiliary dryers now feature what is known as a Switch control system which adapts them to suit different materials and throughput rates. Energy savings of up to 40 % can therefore be made.

The microprocessor control unit designed inhouse guides the user through the program in a self-explanatory manner. All relevant operating modes are available. These include the temperature of each container to a precision level of +/- 1 °C, the run time of operating cycles, the set timings and the operating program selected. The timer clock switches the KKT dry air dryer on at the right time.

The dry air dryers work with two drying containers which operate alternately. This enables a dew point of approx. - 35 °C to be achieved. This represents a value of 0.19 g H₂O per 1 m³. The high drying temperature of up to 160 °C also enables highly demanding grades of plastic to be dried. The modular container sizes with volumes of 12, 24, 40, 60, 100, 200 and 300 liters enable the KKT series of dryers to be adapted to suit individual requirements.

CKT 200 granule dryer: benefit-oriented in every detail

From a dew point control system to the patented ECO control system, the CKT dry air dryers are designed to function reliably and for easy operation.
The sophisticated technology in the CKT meets all the demands for careful and efficient drying that will not damage the material and can be used for any plastic granulate.

Features:

• Tested and fully developed granulate drying technology
• Generated according to version 110 up to 2.000 m³/h dry air
• If needed, you can install additional containers in various sizes
• Maximum energy efficiency with the optional ECO control system (standard equipment for CKT 300 upward)
• Full integration in the KOCH modular system
• The modular construction makes it easy to upgrade existing drying systems

Compared to the basic model with function plate, it is possible to control the drying process via a optional touch panel control.

EKO granule dryer: drying quality of the highest standard

The EKO dry air dryers meet the demand for contemporary design and proven technology. They are based on the much-tested CKT technology.
The design and technology of details such as the sliding lock, the flow monitor, the return air cooler and the ECO control system, which protects both the material and the environment, have been adopted. Depending on the temperature of the material to be dried, it is possible to save 20 - 30 % on energy costs. 

With the ECO energy control system, this figure can rise to 40 %.

The EKO is available in the 110, 200, 300, 500 and 800 versions. In accordance with the modular principle, storage containers in various sizes can be added on - either integrated in the drying systems or placed alongside, as you require.

 Dry air dryer type EKO 800

Features:

• Attractive design
• Tested and fully developed technology
• Generated according to version 110 up to 800 m³/h dry air
• Heat exchanger in the pipework for maximum energy efficiency
• Maximum energy efficiency with the optional ECO control system (standard equipment for CKT 300 upward)
• Drying containers available for all sizes
• Full integration in the KOCH modular system
• The modular construction makes it easy to upgrade existing drying systems

The dew point control system

The dew point energy-saving programme delivers savings of up to 45%

There are two drying systems, which differ in terms of energy consumption:
On the one hand there is the energy-intensive system which switches in cycles, irrespective of the moisture in the drying container. This does not take into account whether dry or moist air is being used for the drying process. On the other hand there is the energy saving system; its operation depends on the dew point.
The KOCH dry air dryers take the dew point into consideration as they operate. They do not switch to the new desiccant container until the dew point has reached -30°C.
The dryer always adjusts to the actual circumstances. For wet plastic material, the cycles are shorter; for dry materials, the cycle is accordingly longer.

The benefit is obvious: A lot of energy is saved in the regeneration and the quality of the end product remains consistent.

FASTI KOCH ERD Xpert - granule dryer on top mounted

The ERD-Technology is an approved technology to drying plastic with compressed air. The ERD compressed air guarantees perfect drying results, low operating costs and a virtually maintenance free production.

Pre-dried compressed air (6-10 bar) from air system of the customer become expanded to atmospheric pressure. Thus the dew point of the process air sinks to a low level. Subsequently the process air is heated to the required drying temperature and released into the drying container (drying hopper). The dry air streams upward by the material and is dehydrated the moisture.
