High Performance Process Control 
The system is equipped with sophisticated process technology that ensures dispensing stability. Ultrasonic type level sensors feedback component levels to the automatic refilling system. High precision regulators control the air pressure of the tanks. Material pressure is detected by pressure sensors and displayed in the user interface and in case the maximum line pressure is reached, the system is programmed to run the automatic cleaning function for the mixing head. Water temperature for the temperature conditioning system is detected and controlled by the temperature conditioning system. Temperature sensors detect the temperature of the materials inside the tanks to ensure that the recommended process temperature is reached. Pressurised tanks are fitted with safety relief valves for the safety aspect of the system. High precision dosing pumps enables the system meter the materials in correct mixing ratio. Recirculation pumps provide that the materials inside the hoses are conditioned according to the process temperature required.

The robotic dispensing system is a sealing, bonding and potting/encapsulation solution for electrical enclosures, automotive parts, air filters, luminaries, drum lids, electronic components and many more. The standard configuration includes a low pressure mixing and dosing unit, cartesian or 6 DOF robot, a dispensing table and a temperature conditioning unit. There are wide range of options and automation solutions available to configure the ideal solution for your applications.
Common base frame for the control panel and low pressure mixing and dosing unit and temperature conditioning unit being embedded into the control panel provides a compact design. It is equipped with stainless steel, temperature controlled (optional), double walled (optional) and thermally isolated pressurised tanks. Temperature conditioning system (optional) with heating and cooling features ensures that the temperature of components in the pressurised tanks and mixing head meet the process requirements. A component is mixed with air (nucleation) and stirred to homogenization in the pressurised tanks. High precision and speed controlled metering and recirculation pumps are installed to convey material components from pressurized tanks to the mixing head. Ultrasonic type level sensors feedback component levels to the automatic refilling system. Automatic refilling solutions (optional) prevent exposure or contamination of the component being refilled. All component hoses in the system are thermally isolated and isolation materials are also covered with protection nets.
One component or multi component, we configure our dispensing solutions with a suitable one-component-dispenser or a multi-component-dynamic or static-mixing head based on application requirements. A dynamic mixing head composes of valves, mixing chamber, mixer and anti-dripping nozzle valve system. Dynamic mixer rotates in the mixing chamber with controlled speed. The temperature of the mixing head is stabilised with the heating and cooling function of the temperature conditioning system. The materials mixed and dispensed with a dynamic mixing head are always homogeneous and equally conditioned in correct mixing ratio. A static mixing head composes of valves and a disposable static mixer. 
Additional component tanks can be installed to combine two or more of production processes such as sealing, bonding and potting/encapsulation to configure one dispensing system for multiple purposes for the same work piece. It is possible to combine processes such as dispensing of thixotropic gasket for flat/inclined surfaces and liquid gasket for grooves or a gasket material and an adhesive or an adhesive and a potting product. The modularly extendable design enables the third tank and the relevant process equipment to be installed later into an existing system. This provides our customers greater flexibility in terms of production planning and budgeting. 
The system has operator friendly, graphics based user interface for monitoring and setting up system parameters easily. The user interface incorporates dynamic icons for component levels, temperatures and line pressures; bars for dispense number, components’ flow rate and mixing ratio; buttons for system control, system diagnostics interface, menu based programming interface, CNC HMI interface and advanced help interface.
Easy dispensing software for rectangular or circular paths is included as a standard feature and especially suitable for manufacturers having products with various ranges of dimensions. Special dispensing software offers great flexibility and reduces system programming and setup time dramatically. Operator fills in dispensing data on "dispensing set-up-page” in a couple of minutes and the software generates the necessary G codes automatically.This low pressure mixing and dosing unit is specifically designed to be operated with HS and ECO series three axis cartesian robots. Additional to standard configuration, there are various options available.

Automatic Refilling Solutions
With automatic refilling, there is no need to open the cover of the tanks for manual refilling. Compared to manual refilling, it is an advantage to prevent the exposure or contamination of the component being filled. Also, any risk of damages due to opening of tank covers, such as damages to the components installed on the cover of tanks and damages resulting from opening of pressurized tanks are prevented. In our option package, we offer two types of automatic refilling solutions.
Embedded automatic refilling system
One of the refilling solutions we offer is the embedded automatic refilling system. It is an ideal solution for companies such as electrical enclosure manufacturers, having low production rates and looking for an economical and as well as environmentally friendly solution against manual refilling.
Automatic supply station
Our second refilling solution is the automatic supply station to refill from barrels, drums and IBC tanks. It is especially suitable for companies operating in demanding industries with high production rates such as automotive and household appliances. With this option, in such processes, there will be no interruption caused by manual refilling. Low pressure mixing and dosing unit loads components automatically from the stations when the levels decrease lower than preset value in the tanks
Temperature Conditioning System Optimal polyurethane chemical reaction is achieved under room temperature conditions. If there is no suitable ambient temperature at the production area, we offer temperature conditioning system with heating and cooling features. It ensures that the temperature of components in the tanks and mixing head meet the process requirement.
Installation of additional component tanks and the relevant process equipment
In case the system is intended to be used for combined processes such as dispensing of thixotropic gasket for flat/inclined surfaces and liquid gasket for grooves or a gasket material and an adhesive or an adhesive and a potting product, our option package includes installation of additional component tanks and the relevant process equipment. This also enables to use one dispensing system for multiple purposes of sealing, bonding and potting/encapsulation on the same work piece.
Other options
