The

equipment

is

not

designed

for

exposure

to

dripping

liquids

as

this

condition

is

not

Dripping

liquids

can

destroy

the

integrity

of

the

insulation

system

and

must

be

avoided

.

Metal

equipment

designed

for

the

pro

,

instrumentation

and

control

of

various

types

of

.

\

The

consists

of

one

or

more

vertical

which

are

mounted

side

and

connected

mechanically

and

electrically

together

to

form
