model

equipped

Tem
coupling
is

a

type
of
fan

coupling
which
is

provided
with
a

temperature
control

system

The
conventional

coupling
always

slips
the
fan
at

a

high

speed
under
a

constant

ratio

regardless
of
the

engine

cooling

requirement

The

slipping
ratio
of
the
Tem

coupling
however
is

properly
changed

with
the

cooling
requirement

ON
denotes
that

cooling
is

required
and
the
fan

operates
up
to

about
2

900rpm
When

The
coiled
bimetal
thermostat

installed
on
the
front

portion
of

detects

temperature

The

and
the

is

opened

and
thus

the

is

performed

When
the
air

rises

the

bimetal
is

expanded
and
the

is

opened
silicone
