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.
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.
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.
Versatile, built-in HACCP (Hazard Analysis and Critical Control Point) – with the optional XDL-01 monitoring device which enables continuous and real-time temperature monitoring, which can be downloaded via a USB stick. In compliance with the European Food Act being implemented by many governments.
Porkka Remote Heat Disposal System (RHDS®)
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 utilizing a very small refrigerant charge and reducing running costs. 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.
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.
RHDS® liquid to air condenser can be a wall, floor or roof mounted either externally or ideally within an area where the heat can be utilized such as a warehouse, etc. Noise levels are kept low as only fans are run on the external unit.
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.
