Why a Johnson insulated slide-in
Our Johnson slide-in insulated body for use in a pickup
truck makes for an excellent investment for both small
businesses buying their first refrigerated truck or
larger companies looking for a vehicle to do small
deliveries, or a vehicle to use in dense urban areas.
This is also an investment that pays long term dividends.
Johnson truck bodies have earned a reputation for
rugged construction and long life. Their fiberglass
construction means you can look forward to remounting
your body on several chassis. Transfer of a body is
fast and relatively inexpensive.
Consider the benefits of fiberglass
Fiberglass truck bodies are 26% more thermally efficient
and 896 times more resistant to heat transfer than
With fiberglass construction the refrigeration system
doesn’t work as hard. Your equipment lasts longer
and is less expensive to operate.
Fiberglass-insulated body construction uses no rivets
and is seamless so there is less moisture penetration
and the insulation deterioration that results.
Fiberglass is more puncture and tear
resistant than aluminum.
What are my refrigeration options?
In a word- Lots
Your Johnson slide-in body can be mounted with a mechanical
blower system. Because these units run off your truck
engine they are lighter in weight and provide on-demand
refrigeration. If your operation needs product carried
at different temperatures this is the type of system
Your Johnson body can also be outfitted with a cold
plate system. This is a simple, proven technology
that offers some outstanding benefits that can’t
be found elsewhere. Cold plates are large metal envelopes
filled with a solution calculated to freeze at a specified
temperature. A reliable electric compressor on the
front of the body pumps refrigerant through a piping
system inside the plates to cool the solution until
it freezes. This is the “charging” process
and is generally done by plugging the compressor in
at night while the truck is parked. During the day
while the truck is making its deliveries the frozen
plates will “discharge” providing the
refrigeration energy needed to maintain proper body
temperature. Because the plate solution is calculated
to have it’s change of state” from solid
to liquid at a certain temperature the maximum amount
of refrigeration energy is released at that temperature.
A plate system therefore is temperature specific and
that is a limitation.
There are some great benefits to a cold plate
For frozen and deep frozen applications cold plates
allow you to “bank” much more refrigeration
energy than a mechanical unit can produce in most
situations. On a small truck, over a twelve hour period,
a cold plate system provides the most refrigeration
capacity of any available system. A plate system will
provide refrigeration when the truck is turned off
and parked for deliveries. Plate systems have fewer
moving parts and even those parts are of a simple,
proven design. Plate systems have no blower motors
and fans. With the use of a strip curtain on the door
there is very little air exchange and subsequent loss
of the cooled air inside the body.
For medium temperature applications a plate system
provides reliability. It also gives you the ability
to leave product in the body overnight because you
have refrigeration capacity while the plates are being
recharged. If you have a product that is sold by weight
you’ll have less dehydration and loss of weight
without a blower system. As an example if your product
is shellfish your product will retain more weight
Plate systems have to be plugged in
and charged before use. Plate systems weigh more than
mechanical systems. However plate systems offer greater
simplicity and reliability than mechanical systems.
On a plate system refrigerant travels through metal
piping as opposed to hoses on a mechanical system.
The compressor on a plate system has a motor that
is an integral part of the compressor eliminating
belts and shaft seals. Having a plate system means
not having to worry about an engine drive belt snapping
or a pulley seizing stranding you and your truck.
There are no intransit electronics on a plate system.
Once they are charged your plates simply suck up heat
from the body. If you’re in an outlying area
and travelling for service is an issue reliability
becomes an important consideration.
It’s nice to have choices.
