INDUSTRIAL COLD ROOMS:

Precise temperature and operation control of display cases and cold rooms are vital for high-quality and safe food products. You have several options to achieve optimum operating conditions of display cases and cold rooms. You can choose either remote control, i.e. connected to a separate compressor rack/pack and condenser, or you can opt for a self-contained unit, where the entire system including compressor and condenser is housed in the unit.

Available as:
• Reach In Cold Rooms
• Walk In Type
• Modular cold rooms,
• Combi cold rooms,
• Industrial cold rooms and
• Made to measure cold rooms.

What are Modular Cold Rooms?
Modular cold rooms are commercial sized refrigeration rooms, supplied in flat pack format for easy construction on site. The walls, floor and ceiling are made up of standard sized panels which are easily locked together. This enables a large variety of different sizes and configurations of cold room to be created using a small set of mass produced elements. For the end customer, this offers a highly tailored solution to fit whatever space they have available, but without the expense of a custom built room.

The panels used to construct modular cold rooms are highly efficient insulation materials encased within surfaces which are made from accredited food safe materials and are easy to clean. The standard surface is galvanized steel sheet coated with food safe polyester, but stainless steel is also available.

Modular cold rooms can be used to chill or freeze at any temperature range.
The three main temperature ranges supplied by ASL are:
Chiller (between 2 and 12C): Used for dairy, vegetables, prepared meals etc
Medium (between -2 and 5C): Used for fresh meat and fish
Freezer (down to -22C): Used for frozen goods of all kinds

Although food is the most common type of stock to be stored in modular cold rooms, they are also widely used for non-edible but perishable goods such as chemical or medical supplies, or other organic produce such as flowers or seeds.

Modern modular cold rooms, such as those supplied by ASL, do a lot more than simply keep stock cold. They also include a range of sophisticated design features to ensure the safety of personnel, compliance with food safety legislation, ease and efficiency of use and much more.

Combi Cold Rooms
The typical internal layout for combi cold rooms is to divide the room into two. The external access door leads into the warmest of the two zones (usually the chiller zone). One of the walls of the chiller zone will house an additional door which leads into the colder of the two zones (usually a freezer zone). Each zone is controlled by independent refrigeration units.

What are Walk- In Cold Rooms
Both the modular cold rooms and combi cold rooms described above are examples of Walk In Cold rooms. These cold rooms are simply cold rooms which are designed to enable a person to completely enter the room. Whereas a cabinet refrigerator holds stock immediately behind the door, a Walk In Cold room will have stock stored on shelving away from the door.

Walk In cold rooms become necessary when the amount of stock to be stored exceeds a level which can be easily accessed via a cabinet design, or which exceeds cabinet volumes.

What are Made to Measure rooms?
If a client has requirements which cannot be met using the modular or combi options described above, ASL can provide a made-to-measure cold room. This is a custom-built room which can be created to fit just about any dimensions required by the customer in multiples of 15cm in any dimension, giving a greater range of size options than the standard modular cold room options.

What are Industrial Cold Rooms?
Industrial cold rooms are designed to deal with volumes much higher than 20 Metres.
While the cold rooms discussed above are designed mainly for personnel access, with perhaps some trolley access, industrial cold rooms are designed to store bulk quantities of goods and can involve access by vehicles such as forklift trucks taking pallet loads of stock in and out of the room. Apart from simply being a great deal bigger, industrial cold rooms will have different design features to accommodate the different type of access and internal storage, such as larger doors and pallet racking.

GLYCOL CHILLERS & ICE BANKS

This cooling technology is high performance; it cools considerable quantities of water and enables the dispensing temperature to be kept constant even when continuously dispensing many liters.

The “ice bank” cooling system consists of a stainless steel coil and a copper coil immersed in a reservoir full of water. The copper coil containing the refrigerant gas freezes the water contained within the reservoir producing a cold supply, which in turn cools the drinking water flowing through the stainless steel coil.

In this way the water cooler offers greater performance and in particular it ensures the hygiene and quality of the water which is continuously flowing and never still in the reservoir.

Recently, the ice bank has been completely redesigned and equipped with technical features offering enhanced efficiency and performance. The new design allows for space optimization and an increase in the thermal exchange surface, so as to increase the production of ice within the reservoir and hence the cooling capacity.

The Ice Bank system is a simple technology based on storing cooling capacity at night and using it the following day to cool. At night when electricity is generated at less cost, chillers cool fluid and store it normally as chilled water or ice where a high cooling capacity is required for short, defined periods.\

Using ice as the cold storage medium, cooling temperatures of between 0 and 1 °C can be achieved. Should cooling temperatures of less than 0 °C be required, such as for storage tank cooling at a brewery, we recommend the use of a glycol ice bank.

This allows processes to be cooled for short periods down to -3 °C.
Benefits of the ASL Glycol Ice Bank:
• Cooling temperatures down to -3 °C
• Low nominal cooling capacity of refrigerator unit and thus low electrical load
• Use of low-cost electricity tariffs for making the ice, with future option of intelligent power meters (time-variable tariffs)
• Economically viable (low electrical load, high melting capacity at low cooling temperatures)
• Low servicing costs as refrigeration unit is small
• Lower refrigerant filling quantity (no leakage testing under 3 kg, climate-friendly)
• Simple, user-friendly system construction
• Plug-and-play technology, completely assembled and tested at our factory (24-hour test run for compact systems)
• Installation on site for split systems if required
