Version 15/3/2000 CCD2 - EVAPORATORS 10 PLATE DESIGNS

Version 15/3/2000 CCD2 - EVAPORATORS 11 CONCLUSION TECHNOLOGY OF THE EVAPORATORS zThe volume of the evaporators was decreased while keeping the same level of performance. This was due to the technological advantages of the plate/fin evaporator over the tube/fin evaporator. zThe optimization of the different parameters allows us to produce today evaporators with a thickness of 60 mm. zThe range of the 60mm evaporators covers all the needs of the market. zThis technology facilitates the standardisation of a range of evaporators and allows a large volume production process with a decrease in costs. zThis last item is a strong demand from our customers. zIn the future, the dimensions of the evaporator are going to decrease just like the costs.
