Reflow furnace

Heller Heller 1700EXL

Heller 1707 EXL in excellent condition.
Year of manufacture: 2000

Features:
The 1707 EXL is designed for high-mix, medium-volume production—operating at speeds up to 24 inches (60 cm) per minute, while maintaining an efficient use of factory floor space. Rapid response times and precise temperature controls ensure consistent process results, regardless of component density or board loading, with identical profile performance in both air and nitrogen environments.

The Model 1707 EXL integrates advanced design features with Heller Industries’ renowned engineering expertise and leadership in reflow technology:

Maximum Yields and Accurate Process Control
• Highly efficient heat transfer through extra high-volume, high-velocity heating modules, achieving heater module response times of under one second for temperature changes below 0.1°C—ensuring profile stability even with heavy board loads.
• Broad process window for universal profiling, accommodating various board types under a single temperature profile.
• Each system is supplied with:
• Advanced PCB profiling with 3 thermocouples and comprehensive process parameter logging, supporting storage for up to 500 temperature profiles and 500 profile graphs.
• Cpk software for real-time Cpk calculation—monitoring oven performance, repeatability, and providing Cpk data for each zone and the entire oven. An exclusive Heller feature.

Lowest Cost of Ownership
• Computer-controlled automatic lubrication system allows 'hands-free' maintenance.
• Optional flux separation system removes up to 95% of flux from the oven tunnel—significantly reducing maintenance and enhancing environmental protection.
• Pure forced convection design conserves nitrogen; consumption as low as 700 SCFH at 500 PPM.*
• Low KW design minimizes electricity use and shortens warm-up and profile changeover times.
