Modular Step-in Cold Rooms - Porkka

Modular Step-in Cold Rooms
NEW DESIGN FEATURES OF OUR MODULAR STEP-IN COLD ROOM RANGE INCLUDE LOWER
ENERGY CONSUMPTION COMBINED WITH IMPROVED PERFORMANCE

Porkka used daily throughout the world
Cooling units produced in our own factory have been designed to be both powerful and energy efficient. Digital temperature displays have built-in
high/low alarms which are both audible and visual. These can be connected via a volt free relay to a building management system. The controller is
also equipped with HACCP features to meet the more stringent temperature monitoring regulations being enforced. The unit or units can be
connected to an independent monitoring server and temperatures automatically recorded via the internet in real time. An alarm can also be sent to
GPRS enabled mobile phone, a PC or an e-mail.
Carefully planned materials and details
Porkka rooms are produced from modular CFC/HCFC-free polyurethane
insulated panels which are moulded with male / female joints
and held by eccentric action cam-locks, giving great all-round
strength. The visible exterior surfaces of the panels are coated with
durable scratch resistant polyester, which is classified as food safe.
Insulation thickness with excellent thermal efficiency is 80mm as
standard with an option of 100mm for freezer application if required.
Doors are semi-rebated and supplied with heavy duty hinges and a
lockable door handle with emergency entrapment release. Thresholds
and surrounds are produced from durable stainless steel with a heater
supplied for freezer application. Doors are already pre-mounted on a
panel for ease of assembly in the field.
Floors, when supplied, are insulated and have a strong marine
plywood surface, which is coated with a non-slip glass fibre resin.
Load limit for a standard floor max. 40 KN/m 2 or max 1,0 KN/ per
40mm castor. Heavy duty floor with stainless steel surface available
as an additional accessory.
A newly-designed hygienic shelving system allows the operator to
wash individual shelves in a commercial dishwasher whilst larger
dimensions increase storage areas within our rooms.

The Porkka modular cold room shelving system is highly
practical and easy to clean. Standard shelving delivery includes
four (4) tier dishwasher safe polycarbonate (food safe) inserts
and supporting material. Shelving is supplied for either 2 or 3
walls dependent on model selected.
Safety
The door is supplied with heavy duty hinges and a lockable door
handle with a luminous emergency entrapment release, which
overrides the lock at all times, should someone accidentally be
shut in the room. Door threshold and surround is fitted with a
heater to prevent freezing of the gasket to the frame in low
temperature models. If required floor panels can also be
supplied with built-in heaters to prevent freezing or moisture
damage below a larger freezer room.
Trolley operation
To facilitate the use of trolleys, chill rooms can be supplied
without a floor. In this instance, the room is erected on an
insulated plinth and the door equipped with a sweeper gasket.
The installation package contains all components. Medium and
low temperature rooms must always be supplied with a floor. If
trolley use is essential, it is possible to recess the floor, or, if
above ground, supply an optional ramp. In either case, the doors
are fitted with a sweeper gasket.

New Unique Porkka Shelving System
Porkka has designed a totally new shelving system for our standard range of
rooms. We have focused on improved hygiene features, flexibility and greater
surface area, for more storage space. The support pilasters are fixed to the
insulated wall panels, which are positioned to allow easy all round cleaning of
the floor.
Four (4) tier shelving is supplied as standard. In rooms with a width up to
1500mm, shelving is supplied to two (2) walls and in rooms with greater
width, shelving is fitted to three (3) walls.
Installation is simple and quick. Place shelf support brackets at desired height,
fit support bars horizontally into the ready made openings and place shelving
inserts between the bars. The tough, strong inserts are produced from plastic
that is approved for use with foodstuffs. Even the largest shelving insert 300 x
462mm can fit into most commercial dishwashers.
It is also possible to purchase additional shelves which can be easily added at
a later date to facilitate further storage space.
The depth of rear wall shelving will be 488mm and dependent on room
model, the total depth of side wall shelving will be either 398 or 488mm.
The shelving can be evenly loaded with up to 70Kg per meter run i.e. 280 Kg
per 4 tier shelving meter run.
Shelf support brackets
together with horizontal
bars are simple and quick to
install and are designed to
be strong and durable
under heavy loads.
Shelf inserts have been
produced from high density,
durable plastic, which is
approved for use with
foodstuffs. They can be easily
taken out and washed in a
dishwasher or by hand for
improved hygiene.
Pilasters affixed to wall.
Note that shelving can now
be placed much closer to
the floor level than in the
previous range. Sufficient
space is still available to
allow cleaning of the floor.

Easy-to-adjust shelves are strong and machine washable.

Porkka Remote Heat Disposal System (RHDS)
When placing Porkka modular rooms within a building, lack of
ventilation can cause heat to build up and increase running costs. The
solution is to use the Porkka Remote Heat Disposal System. Porkka’s
RHDS offers an easy and inexpensive method of transferring waste
heat produced by the refrigeration systems to either an external area
or an area where the warm air could be utilised. It is easy and quick to
install, with the additional benefit of being much quieter than fitting a
conventional condensing unit.
The RHDS system is similar to the standard Porkka unit with the
addition of a liquid condenser, header tank and pump. Water pipes are
then connected from the remote condenser to the refrigeration unit.
After connecting the system it is filled with a water glycol solution that
will operate in both summer and winter conditions. The multi-fix
condenser can be positioned either within an area that will benefit
from heat input or externally. The unit can be floor or wall mounted. In
addition the equipment benefits the environment by utilising a very
small refrigerant charge and reducing running costs.
The Porkka RHDS unit is equipped with
a refrigerant-to-liquid heat exchanger.
Waste refrigeration heat is transferred
to the water solution where it is
circulated to the condenser where the
heat is given up to the ambient air.
Installation of the equipment is quick and easy and can be undertaken
by competent installers that do not necessarily have to be qualified
refrigeration engineers, though they are recommended. The RHDS can
be used throughout our standard range of rooms and at all
temperatures i.e. chilled, medium or freezer versions. For a standard
installation, a pipe can be run as much as 25 meters horizontally with
a maximum vertical lift of 4.5 meters within the run, the height of
which is measured from the pump within the refrigeration unit.
RHDS liquid to air condenser can be
wall, floor or roof mounted either
externally or ideally within an area
where the heat can be utilised such
as a warehouse, etc. Noise levels are
kept low as only fans are run on the
external unit.

Porkka XWEB HACCP monitoring
Porkka XWEB is an independent monitoring and alarm
warning control system for refrigeration equipment. XWEB is
a compact powerful computer that operates as an
independent network server complete with its own
ready-made web page. Information can be accessed either by
the internet, browser or a GPRS-enabled mobile phone.
Porkka can offer several versions to suit small to large
operators.
The XWEB allows 24/7 monitoring, controlling and adjusting
in real time. It continuously records temperature and alarm
data and will notify specific personnel of equipment failure.
The system can be accessed from any computer as software is
not required to gain entry to the programme.
Simple supervision
Compared to traditional, passive monitoring the Porkka
XWEB offers real time temperature monitoring and alarm
notification, which can be integrated within an existing BMS
(Building Monitoring System). Browser facilities enable access
for holders with a username and password at several levels if
required. Information distribution to all relevant personnel is
also quick and easy.
Reduced operating costs
Monitoring real time temperature data can give quick and
effective information on how a particular item of equipment
is being used. This in turn can allow the operator to control
the operation of the equipment more effectively and reduce
energy consumption. Maintenance personnel can also gain
valuable information from data, such as when servicing is
required. This also has the effect of reducing main component
failure which reduces overall running costs.
Intelligence = knowledge
Porkka XWEB allows the operator to use the refrigeration
equipment being monitored more effectively which is better
for the environment. The system can, for example, record door
openings (for devices fitted with a door switch), defrost cycles
etc. This in turn can highlight critical points in the operation of
the equipment, for example, when doors are kept open for
too long when goods are being received. After training,
energy cost can be reduced.
Device information
Within the Porkka digital temperature display is a
circuit board equipped with a TTL connection.
A RS485 adapter is available as an optional extra.
The control unit uses Modbus RTU data transmission
protocol. Items of refrigeration equipment are
connected to a Porkka XWEB computer (operating
system Linux). You may select from several models
which can monitor continuously up to 12 units, the
largest able to cope with up to 230 units. There are
also software solutions to cater for different
requirements.
A good idea is to digitally photograph each item of
equipment when installed, then the graphic user
interface can display real time information on the
equipment’s temperature and operation.
To connect to a network use a RJ-45 cable and
specify it to a fixed IP address. This will allow
continuous connection for several users. Smaller
users can connect the system to a telephone plug
via a modem, but only one user can access at any
one time.
