LR PERIPHERALCONVERTING PRODUCTS
VISCOCHECK- Automatic ink viscosity control and regulation - Conventional or vibrating sensors available- High precision and accuracy - Intelligent algorithm control - Automatic cleaning when installed on a autowash
VISCOCHECK TC- Ink temperature control system- Automatic cooling or warming the inks - Highly efficient heat exchangers- Consistent Ink pumping pressure- Ink settings maintained throughout press run - No additional recirculation pumps
AUTOWASH
The operation of the pumping and washing equipment autowash, is based on the use of a reversible pneumatic pump for each printing unit. Pneumatic double-pumping systems have serious regulation problems of the synchronism between pumping and suctioning units.
This technical solution allows, by this apparent simplicity, an extremely efficient and trouble-free operation.
The equipment provides total integration for the lr.products) ink control systems, including all possible options.
AUTOMATIC WASH-UP:
CHANGING OVER TIME REDUCTION
CONTROL OVER THE INK VARIABLESFOR ANY TYPE OF FLEXO PRESSUSING CLOSED CHAMBER SYSTEM
VISCOCHECK PH- Water-based ink pH regulation - Accurate pH control at all times - Avoids uncontrolled pH solution additions to the ink - Proprietary self-checking software monitoring the pH sensors with alarm if out of calibration

AUTOMATIC WASH-UP:
REDUCES DRASTICALLY THE CHANGEOVER TIMES FOR INK WASHING ON PRESS
Main advantages using the AUTOWASH technology
1- Compact design in a single reversible pump, for all functions
2- No over-pressure issues due to failure on the double pump synchronism
3- Ink accumulator to minimize keystrokes
4- Easy maintenance of the pneumatic pumps
5- No siphons or dark areas for washing-up
6- It allows the selection of units to wash-up
7- Consumption of solvent adjusted to chamber size and hoses
8- Washing cycles are customer programmable
The AUTOWASH washing-up cycle description
1- Ink pumping to the chamber, return by gravity2- Suction of ink and returning into ink bucket3- Washing-up with clean solvent4- Suction of washing-up solvent and returning to the common collector5- Dirty solvent collector draining
