WORKING PRINCIPLE
The LARIUS NOVA MIX 2K is a bi-component mixing machine. It therefore provides for the dosage, mixture and application of bi-component products. This machine allows the user to work in high pressure with manual or automatic spray-guns. The dosing and the mixing of the components are regulated by an electronic control system. The hydraulic unit contains two flowmeters which regulate the input of the two components into the mixing lines. It is here, thanks to a static mixer, that the mixing of the products takes place. The machine is made up of 4 main units:
The pump for the components unit
The hydraulic mixing unit
The command and control unit
Equipment supply

These mixing blocks have been designed to allow the operator using the LARIUS NOVA MIX 2K to check that the mixing ratio of the two components is correct. The operator must perform the following procedure in order to check the quantities of the two components just before they are mixed:
Mount the component tapping blocks (G18).
Open the valves (G19) and set the tapping cycle in order to
check the dosage of the components.
The machine must not be pressurized.
By positioning the 2 containers (G20) in correspondence
to the 2 outlets, the operator can check the actual amounts dispensed by the machine.
During the normal tapping phase, the valves (G19) must always be open. During the normal working phase, the two blocks (G18) must not be mounted.

The fluid is drawn into the system by the wash pump.
This pump ( GHIBLI ) filters the wash fluid before sending it
into the machine.
The wash fluid through the nozzle located on the mixing block.
From there, they proceed to clean out the mixing line as well as the tube containing the mixture of the 2 components.

Flow diagram for the 2 components
The components are drawn from either external tanks or from
gravity tanks.
The 2 pumps ( NOVA ) send the components to the NOVA
MIX 2K machine.
In the NOVA MIX, the components flow through the pressure
gauge and the mixing group.
The components then enter their respective nozzles located
on the mixing block. Based on the settings provided by the machine, these regulate the passage of the materials in order to obtain a proper mixture.
Along the length of the block and of the mixing tube, the 2 components are mixed together until they arrive perfectly mixed at the spray-gun’s outlet.
- It is recommended to ALWAYS keep the cataly­ser in part B of the circuit, both in the machine as well as in the flow pump, and to use part A exclusively for the product.
- Make sure that the wash fluid, whether water or solvent based, is compatible with the two components being utilized.
- If one or both of the components is changed, perform a “complete” washing cycle in the NOVA MIX 2K system.
