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. 10 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.
