The APSON Lacquer Changer LCLT-25K4
Inline is a modular expandable switching unit for pressurized
chemically aggressive work materials, e.g. paints, solvents, alkalis. It
is an evolution of the standard lacquer changer type and belongs to the
class of inline paint changers with large inline throughput for many
delivery points. The paint changer consists of a maximum of 23 switching
blocks. Each block is provided with 1 throughput
channel (inline channel) and 4 independent output channels
(A-B-C-D). Each output channel of a block is independent of the
other output channels and can be fitted with pneumatically controlled
APSON valves or APSON locking screws. This lacquer changer type is also
deliverable as piggable/newteable
execution (APSON LCLT-25K4- N, Lacquer
Changer for recovering the residual amounts).
Due to the multi-channel, economical A-B to
A-B-C-D systems or special applications are realisable. All
four output channels can be switched through to the same paint, or any
output channel can be switched through to a different paint. The piggable
execution of the paint changer allows coating processes without work
breaks (back pushing of the residual quantities, flushing the lines,
re-charging with new work material), because the inactive part of the
system can be used for recovering the residual amounts of old paint type
and for pre-charging with a new type of paint, while a different part of
the system is producing.
The piggable APSON LCLT-25K4-N
enables almost complete recovery of the residual amounts by back pushing
the work material from the supply lines and paint changers into the supply
system. It offers large material throughput and allows, due to the
construction and the used dead-space-minimized APSON valve technology,
very good rinsing of both, the supply lines as well as the output lines of
the paint system.
Large inline throughput and very good rinsing, N-version is piggable.
Environmentally friendly due to short rinsing times and work material recovery (N version)
Modular expandable to the desired number of media (up to 23 blocks).
Dead-space-minimized valves, and rinsing- and throughput-optimized ducts.
Cost-saving due to 4 channels and minimal work material consumption.
Easy handling during installation and maintenance.
Material: Stainless steel, therefore durable and wear resistant.
Resistant to alkalis and weak acids.
3. Structure and Function
^^ to top
The APSON LCLT-25K4 Inline consists
of a maximum of twenty-three switch blocks, each with a large inline
channel (DN25) and with four output channels (A, B, C, D). The uppermost
block and the lowermost block (end blocks) are special blocks for
assembling and fixing the paint changer and for connecting the output
channels. Long lacquer changers with more than 11 blocks have a special
block (center block) with threaded holes for assembly by means of threaded rods.
Each block has four screw sockets for pneumatically controllable
APSON 2/2-ways valves. Thus allows per block, that the associated inline
channel can be switched through to max. four output channels. The blocks
have to each one end of the output channel one O-ring (per channel) for
sealing the adjacent blocks, and two pins for aligning the blocks when
assembling the paint changer. The components are made as standard of
stainless steel. For rinsing (rinse cycle), the respective valves of an
external cleaner group supply several times alternately, for a short time
air and solvent into the to be rinsed output channel of the paint changer.
