Drying plastic granulate
Dry air technology
by KOCH-TECHNIK
The KOCH-TECHNIK dry air dryers dry medium up to very large amounts of plastic granulate with dehumidified air until the residual moisture is at the optimum level required for processing.
This dehumidified air technology is an energy-saving closed circulating system that functions completely separately from the ambient climate. Dry warm air flows through the granulate, absorbs the moisture on it and releases it to a desiccant.
Compressed air technology
The drying hygroscopic granules with compressed air is for small capacities the more economic alternative compared to another drying systems. The special ERD-compressed air technology by KOCH guarantees perfect drying results, low operating costs and a virtually maintenance free production.
The result: continuous drying performance, maximum reliability, easy handling and less space requirements.
Granule Dryers with Dry Air Technology
KKT - The Mobile Dry Air Dryer
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.
Equipped with three programs, it can be adapted to suit all requirements.
- the economic power saving program saves energy costs of up to 40 %
- the basic program serves your standard production facility
- the high-speed program is designed for maximum material throughput levels and optimum quality

Dry air dryer type EKO-N – drying quality at the highest level
EKO-N: Drying quality at the highest level - here the EKO-N 1100F with a total of 16 drying containers
NEW dry air dryer TYP EKO-N – Drying quality with biggest energy-saving efficiency
The pros of the existing drying concepts CKT & EKO together in one drying unit: The dry air dryer EKO-N
The heat exchanger concept in the pipe system adopted from the EKO dryer has been further improved in the EKO-N series and is used here even more efficiently. The thermal energy return reduces the energy consumption by 20 to 30%, depending on the drying temperature of the material. This reduces the average energy consumption while maintaining the same quality.
The EKO-N dryer includes frequency-controlled drying fans and the energy-saving dew point control as standard (both from EKO-N 300F). The patented KOCH-ÖKO energy system control is available for the EKO-N drying containers for the greatest possible energy savings, which adapts to the drying process in an energy-saving, material-friendly and intelligent manner. In the combination of dew point, eco-system control and frequency-controlled fans, energy savings of up to 50% are possible when drying granules.
KOCH dry air dryer type EKO-N 1100F: The 16 drying containers are recessed into the floor of a mezzanine.

The EKO-N 200F, here with two drying containers (300 liters each), on a mobile frame.
According to the modular KOCH construction kit principle, different drying containers from 20 litres to 600 litres can be integrated into the EKO-N. Another advantage: Due to the modular structure of the drying system, Expansion of drying containers can be carried out without any problems. Nine different dryer sizes from EKO-N 110 to 2000 (m³ / h) are available.
In addition to the Siemens S7 control, all EKO-N dryers have a 10.4-inch touch panel display. This allows the user to have all relevant operating states and information clearly displayed and to adjust parameters such as drying time, temperature and dwell time at any time. The drying process is continuously monitored by sensors. In order to absorb the moisture in the granulate and to achieve the required residual moisture in the material to be dried, it is possible to generate dry air with a dew point of -55 ° C.
The EKO-N is Industry 4.0 compatible thanks to the OPC UA communication standard and can be fully integrated into the KOCH-Visualization-Software.
Dew Point Control and KOCH patented ECO Control System
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.
The KOCH ECO control system
Our patented control system for gentle, energy-saving drying that does not damage material!
Controlled drying that is economical, gentle on the material and energy-saving ...
Our optional ECO control system guarantees that hygroscopic materials such as PA, PC, LCP, POM etc. do not become overly dry in the storage containers.When little or no material is removed from a storage container, there is a risk of material damage occurring due to the constant flow of hot air. The ECO control system stops this happening.
When a certain temperature is reached at the top of the storage container, the drying system automatically switches to idle. The machine only begins to operate again if material is removed or the holding time is too long. The advantage is that you save up to 50% on energy and can access pre-dried material at any time.
At the same time, you can be certain that no damage has been done to the material. The quality of the end product is thereby ensured.
Other features:
- The regulating system takes into account the amount of air needed in the container
- The defined air quantity can be regulated - irrespective of the amount and type of material in the container
- The air flows through the container in exactly the quantity required
- Optional automatic load adjusting system
