Now there are a lot of booking BHE volume production sector is required, in small quantities of 1# Test on-line test, 1# Test line has now become a BHE production bottlenecks, having a serious impact on the development of the production BHE heat exchangers distribution, see 2012.

Presently the BHE production department has massively subscribes the quantity is the small batch, had to carry on the test on the 1# slotted line, the 1# slotted line already becomes the BHE production the bottleneck, has affected the BHE production development seriously, saw in 2012 the heat interc

BHE production sector has a large number of such small quantities, on the 1# line you want to test, 1# test line has now become the BHE production bottlenecks, BHE production was seriously affected development, see 2012 distribution of heat exchangers,
