FINELY REMODELED
Splendid System of Refrigeration
and Cold Storage
1t Solves the Problem of Handling
Perishable Products and Adds
Greatly to Sanitation

After a number OF weeks spent In
the remodeling of their model grocery
store and market and the installation
of refrigeration plant, L. Alt &
Sons now have their big task COM
pleted and everything will be open
to the inspection of the public next
Saturday June 90.
The central feature of the improve
ments this firm have made in their
store and to which all other features
are auxiliary. is the cold storage and
refrigeration.
The cold storage plant today is rec.
ognized by the modern business man
as a necessity to the business of dealing
in perishab bic food products. A much
lower and more even temperture can
be maintined. enabling the stored
goods to be kept much longer in
perfect condition. The storage rooms
are always in dry and sweet condi-
tion which is not possible with ice
refrigeration.
The plant which Alt & Sons have
installed is known as the Born
Special. manufactured by the H.
A. Born Company. of Chicago. This
consists of an 8-ton brine circulating
and reserve storage system, which re-
quries only about four hours daily
operation to take care of one big main

wall case 26 feet long, feet wide
and 10 feet high; one handsome 90
foot display case and one basement
cooler 1924 feet. The latter is for
the storage of noked meats, vege
ia bles, fruits etc. In any or all of
the compartments the temperature can
be held at any degree desired from 80
to SO degrees. with but little ductua-
ton.
The process of mechanical refrigera-
tion is merely transfer or extraction
OF heat, with the help of machinery.
from the goods and spaces to be
cooled. to some convenient medium
that will absorb this heat and carry
it away.
The best and most useful of all
heat absorbents has been found to be
ammonia. As pure ammonia is very
expensive to produce it was necessary
to find some means of contnIng it and
using it over and over again.
This has been accomplished by al
lowing pure ammonia to expand in
system of pipes where the heat is to
be extracted, and then with the help
of machinery and more piping to re-
duce this gaseous ammonia to a liquid
state again by which process it is
possible TO use it continuously The
gaseous ammonia, which is the am
monia in vapor for n, passes
through the coils of pipe at a
temperature of 90 degrees below zero,
and in the test before the plant was
accepted it was shown that it could
be forced down to the remarkable de-
gree of So below.
The ventilated ice pan and its at
tendant apparatus is so constructed
that the cold air descends upon one
side of the cold storage rooms and all
the heat. moisture and odors are
drawn to the opposite side, by and
through tiue-like arrangement, and
passing upward. When the top of
the fue is reached they are DETECTED
back into the brine tank and there
absorbed. They are thus condensed
by contact with the ice and the odors
leave the refrigerator commingled
with the ice water. This purifies
the air. and after chilling it again
descends, repeating the same cycle of
circulation as long as there is any
heat moisture or odors to be absorbed.
The circulation being but in one
direction, there are no counter cur.
rents to form condensation on the
bottom of the pan, as is the case
with other ice pans
The freezing tank cools the base
ment cooler as we'll as the up stairs
coolers and refrigerated coun ters and
at the same time freezes 800 pounds of
clean and sparkling artificial ice,
made from the pure spring water
furnished by the city service, every "a
hours.
A lotion compressor operates the
plant driven by a..1O-horse power cleo
trio motor, while a 5-h. p. motor
drives the other machinery-a sausage
cutter, meat chopper, bone grinder,
etc. A 3-h. p. motor operates the
electrically operated automatic eleva-
tor, This power was installed by
the Lancaster Electric Light Co.
We do not know of an institution
in this section of the country that has
an equipment which in anyway ap
