Used HELLER 1912EXL #9255278 for sale

HELLER 1912EXL is a convection reflow oven used in the manufacture of printed circuit boards, commonly referred to as PCBs. The main purpose of HELLER 1912-EXL is to heat solder paste in order to create electrically conductive joints between the components and the PCB. This process is known as "reflow" and is essential in PCB assembly. The oven itself is a predominantly metal construction comprised of an insulated enclosure with two magnesium rods which hold heating elements. The Hellershell design ensures that the heating elements heat evenly and prevent hotspots, while ensuring an effective, equipment-wide thermal management. The interior of the oven is also equipped with a circulation fan to ensure a consistent temperature is maintained throughout the entire chamber. Heat is applied via the upper and lower heating elements in precise, evenly spread bursts. In terms of size, 1912 EXL is relatively compact, measuring just over four feet in length, two feet in width, and three feet in height, with a total volume of approximately 120 cubic feet, making it ideal for use in smaller production facilities. Its maximum reflow temperature level is 500°C (932°F), with a accuracy of ±2%. It has various features such as a fault indication system, an LCD display, a programmable controller, a motion detector and an adjustable speed conveyor belt with a width of 400mm. 1912EXL also incorporates an integral exhaust unit to remove the acidic substance and odour produced in the reflow process, protecting the operator from hazardous fumes while providing a safe and comfortable working environment. Overall, HELLER 1912 EXL is a reliable and efficient reflow oven designed to provide consistent and cost-effective production of PCBs. With its accurate temperature control, effective thermal management, superior ventilation machine and programmable controller, 1912-EXL is an effective piece of equipment for any PCB production facility.
