According to we went to Patton aero in afternoon for get to know the problem about plate bending for model EJL2-6R/PL01-ASM-JC08-D which Patton aero worry about quality issue so we would like to explain for the plate bending that occur from heat transfer from brazing process but we confirm that plate bending will not effect to quality of our coils because aluminium material is soft material and we made collar for this plates which support copper tubes.
Anyway ,for this issue and other issues ( lenght of coil over 5 mm and plate bending in vertical) which we will add the check points and improve to brazing process about heat transfer for your coils in next order will not occur like this.
