Porkka modular step-in cold and freezer rooms - used daily throughout the world

Porkka rooms are produced from modular CFC/HCFC-free polyurethane insulated panels which are moulded with male / female joints and held by eccentric action camlocks, 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.

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.
 

Select from our extensive range, for a room to suit your requirements
• Three temperature ranges:
  +2...+12 °C   for chilled products
  - 2 ... +5 °C   for the storage of fresh meat or fish
  -18...- 22°C   for frozen products

• Insulation options of either 80 or 100 mm.
• Select floorless chill rooms for trolley operation (Chill temperature only).
• Medium and freezer rooms must be supplied with a floor which can be either recesse or with a ramp
  if a trolley is required.
• Cooling units can be manufactured for placement either to the left or right hand side of the door and
  can also be made for connection to a central cooling system.
• Door can be hung either left or right-hinged or changed in the field if required.
• Standard external height 2100mm (note 2140mm if 100mm insulation selected) or 2400 / 2440mm
• 4 tier fully adjustable shelving is supplied for either 2 or 3 walls dependent on modelselected.
  Polycarbonate shelves can be washed in a commercial dishwasher.

A large comprehensive range with volumes up to 22m3
Porkka Modular Step-in Rooms are available in a range of 81 different sizes with volumes from 1.2 up to 22m3. All are available to select in three temperature variations with optional insulation thickness and external heights.

Carefully planned materials and details

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.
 

Combined digital temperature display with built-in control functions
The Porkka temperature display is supplied with a built-in high/low temperature alarm which is both audible and visual and can also be connected to a building management system by means of a volt free connection.
 

HACCP
Versatile, built-in HACCP (Hazard Analysis and Critical Control Point) properties enable continuous and real-time temperature monitoring in compliance with the European Food Act being implemented by many governments.
 

NEW ! Memory stick recording
In April 2010 a memory stick based temperature recording system will be available for Porkka cold equipment. The unit, attached in the front panel of the cold equipment and equipped with its own digital display, real time clock and calendar, records the temperature data.
With recording intervals of 15 minutes, there will be room for about one year’s data on the memory stick. Naturally, the recording interval can be adjusted according to the needs. Depending on the length of the recording intervals it will take no more than 15 seconds to transfer the data to the memory stick. As soon as the data has been recorded on the memory stick, the stick will be connected to the USB port of the computer and all the information can be seen on the display. The numerical data is easy to work up with Excel software.
A 24 hours battery back-up is available as an accessory.
 

Air-cooled condenser dust filter
The air inlet to the condenser is on the lower part of the refrigeration unit, ensuring the coolest air is always used helping to reduce running costs and extending the service life of the unit. The dust filter behind the air grill is easy to clean or replace. The controller provides information on when the filter requires cleaning or changing.
 

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.
 

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 runningcosts.

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.
