INCORPORATING COLD CHAIN
EVENTS AND EXHIBITIONS
Adiabatic cooling seems to be the order of the day . The concept is the condenser runs dry and as the operating conditions rise water is sprayed into the incoming air flow , reducing the air to wet bulb temperature which in turn increases the condenser capacity . Not sure if it is a working solution for South Africa .
Upon entering the hall , the GEA stand illustrated larger plant and packages .
This was an interesting stand where they were illustrating detection strips which reacted with Ammonia and
CO 2 depending on the tape selected . If you think there is a leak in an area , wrap the strip around the item and it will change colour and highlight where it is .
Penthouse evaporator units ( we would probably call them pods ) are pre-assembled , permitting the units to be placed on top of cold rooms . This seems to be a trend where all of the NH3 cooling equipment including pipework and control valve stations are all outside of the cold rooms .
Further view of Penthouse unit . The trend seems to be to pre-assemble everything to minimise site construction work and to speed up the installation time .
