Cast Aluminium Cold Plate
These cold plates are made from a thick cast aluminium plate which acts as a large heatsink to absorb heat efficiently from your beer.
Inside the casting contains 2 x 304 stainless product lines which are 5.5 meters long and 6.5mm diameter. The inlets and outlets on the cold plate are the standard MFL threads.
With 20C ambient beer temp and flow rate through the cold plate of 300ml/10 seconds and 70% coverage of ice in contact with the cold plate you will be able to reduce the temperature of the liquid as it exits the cold plate to below 4C with a single pass through this cold plate.
If your beer is warmer than 28C, it is recommended either; slowing your flow rate through the cold plate or alternatively, having the beverage pass through the cold plate twice by looping the beverage back through the second plate line. This will mean you will only be able to serve one keg from the plate chiller but will ensure the beverage dispenses perfectly cold.
The most common way to use this type of cold plate is to attach it to the bottom of an eksy/cooler, drill holes through the esky wall to mount shanks and taps and then glue the cold plate to the floor of the esky with some polyurethane adhesive (waterproof).
- Place the cold plate into your cooler box, esky or ice well. If you want to stop the cold plate from moving around then use some polyurethane-based glue and this will enable you to stick the cold plate down.
- Fill the esky/cooler box with ice. Cold plates require the ice to be in contact with the aluminium casting directly so you MUST drain off the water in order for these cold plates to work at their best (different to cooling coils that require and ice water slurry).
- Set your keg pressure at 20-30psi. It is essential that you use a higher pressure to move the beer through the plate. Just ensure your kegs are sitting at a temperature around 20C as the colder the beverage is, the more likely it will take on carbonation at a higher pressure.
Remedying foamy pours:
When you look at the beer line between the cold plate and your keg, before the beer has gone into the cold plate, just check for visible bubbles or air pockets in the beer line. This will be an indication that your dispense pressure is too low. Simply increase your pressure to the keg to ensure the CO2 stays in solution.
When you measure the temperature of the beverage as it comes out of the tap it should be below 5C. If it's higher, simply ensure you have complete coverage of ice on the cold plate in the eksy/cooler and not just water.
If there is ice contact with the plate, and the temp is still above 5C, simply decrease the flow rate of product through the cold plate so the beverage has more contact time as it passes through the cold plate.
Using just CO2 to dispense your keg is fine for short periods around 6-7 hours. If you intend to go longer consider using a beer/nitrogen mix to decrease the likelihood of over carbonation.
You can also disconnect the kegs and take the additional CO2 out of the head space before storing the keg, say overnight, and then reattach the gas line and adjust to the higher dispense pressure again the next day.
