The Zephyrtronic ZT-1-HIS Digital AirBath (230 V) is an effective solution for preheating PCB's for low-volume prototyping or in rework. It has a powerful 25 CFM (710 Liters/Minute) of air supply. The ZT-1-HIS AirBaths ample air supply from the AirCone delivers its forced-convection preheat power for even the most challenging PCB's. Beware of imitative pre-heaters with less than 13CFM (360 liters/minute) that crudely attempt to compensate for wimpy air volume through higher temp settings. Remember: the glass transition of an FR-4 PCB is only 170-deg C. You don't want higher preheat temps, you want a higher volume of safe preheat (100 to 170-deg C).

The AirBaths with the Zephyrtronics ZeroTouch preheat get into a PCB's nooks and crannies where hot plates and IR preheaters can't go. Fabricated from steel, not plastic for industrial use and long production life, they are RoHS Compliant, ESD-safe, exceed U.S. Military Specs and uniquely feature indicator lights (blue: cooling; red: preheating). All AirBaths have internal air supply so you do not need compressed air hook ups...and the ZT-1-HIS-DPU Digital Model has a very big LED lighted digital temperature display for quick "set & read" not tiny, impossible-to-read, and simply horrible LCD's for displays!).

All Zephyrtronic's AirBaths have the industry standard, temperature ramp of 2 to 4-deg C per second "built-in" to prevent thermal shock to semiconductors, sensitive chips, ceramic caps and glass diodes. Indeed, our integrated ramping was essential to Motorola and Boeing with their space applications. And they are essential for high-quality smartphone, tablet, pc and flat-screen television soldering and desoldering repair.

Zephyrtronic's AirBaths have Greater volume of air supply preheat with far lower temps than with other ineffective preheat devices limited by low air volume outputs, which require higher temps and burn your boards. Not a preheating "toy", this is real preheating! And in our famous trademark pyramidal design! Coupled with ample air output is the 800+ Watts of preheating capacity. This is effective preheating by design!

Flipping a switch the unit transforms into a post-cooler cooling down your PCB, chips, and solder joints. PostCooling is essential to soldering BGA's because hot air nozzles must never be lifted from above a BGA until all the balled joints have cooled to prevent unwanted bridging. Important: hot plates, static ovens and IR plates do not provide the critical post-cooling feature standard on every Zephyrtronics AirBath. Zephyrtronics Introduced PostCooling PCB assemblies to the benchtop clear back in 1994. Zephyrtronic's AirBaths cool BGA's enough within 8 seconds so a hot air nozzle can be lifted without fear of bridging. Without post-cooling techs must wait for the ball/pad interface to solidify completely before lifting a nozzle to inspect. Post-Cooling remedies this problem for rapid lifting nozzles off BGA's after soldering.
