Heller 788 Vertical Format Oven

      The Heller 788 in-line, continuous cure, vertical format oven conveys product from the assembly line onto rails inside the oven... then transports it up, across and back down to the line in a continuous stream... with cycle times as short as 25 seconds. Four internal thermal zones with independent time and temperature controls produce virtually any recommended curing or encapsulant profile, including two-step curing.
