HVN-400U - Class 2 Cooling Vest
The default for general construction. Ships complete with fans, battery, and cable.
Cooling gear for manufacturing plant floors
Process heat doesn't clock out with the weather. Airflow where the plant has none — with one rule that matters more here than anywhere else.
The heat problem in the manufacturing job
A foundry, a stamping line, an oven room — the heat source isn't the sun, it's the equipment. That means it doesn't go away at the end of summer, and it doesn't move when the worker does. Standing near a furnace or a line of running machinery is often hotter than being outside in August.
Most plants have some general climate control, but it's built for the building, not for the specific hot spot next to a press or a kiln. The worker closest to the heat source gets the least relief from it.
What's specified in manufacturing
High-visibility: Less commonly required than in roadwork, but plants with forklift and vehicle traffic on the floor often specify ANSI/ISEA 107 Class 2 for personnel working in those lanes. Check your facility's PPE policy.
Fall protection: Only relevant for elevated platform or catwalk work. ZIPPKOOL garments are harness compatible where needed — the rear opening passes the dorsal D-ring through without affecting fit.
The one that matters most here: ZIPPKOOL garments are not flame-resistant and not intrinsically safe. Do not use near open flame, welding, molten metal, or in atmospheres with flammable gases, vapors, or combustible dust. If your facility requires FR clothing, that requirement overrides everything else on this page.
THE CASE FOR IT
Why fan-cooled works near process heat
01
The heat source doesn't move, and neither does the worker
Personal airflow works at a fixed station in a way that fans overhead often can't reach.
02
It runs the full shift
No mid-shift return to a break room to swap a warm pack.
03
Works year-round
Process heat doesn't follow the calendar, so the gear shouldn't either.
04
Fits with required PPE
No added layer over hearing protection, face shields, or existing safety apparel.
05
Certified for site approval
LI-PRO1U's ETL certification is often the specific thing an EHS team checks before sign-off.
Where it doesn't belong
ZIPPKOOL isn't right for every job
Near rotating machinery.
Fans inflate the garment. Turn fans off and keep it zipped near shafts, conveyors, augers, or power take-offs — the same rule as any loose clothing.
Hot work and open flame.
ZIPPKOOL garments are not flame-resistant. Not for welding, cutting, furnace-adjacent work, or anywhere FR-rated clothing is required.
Hazardous atmospheres.
Not intrinsically safe. Not rated for areas with flammable gases, vapors, or combustible dust.
It doesn't replace the basics.
Supplements — doesn't replace — hydration, rest, shade, and acclimatization, even indoors.
FAQ
Questions we get from safety managers
The specification and compatibility questions that come up most.
Is this safe to wear near conveyors and rotating equipment?
Only with the fans off and the garment fully zipped. Running fans inflate the garment and increase entanglement risk near any rotating machinery — treat it the same as any loose clothing.
Can this go in a hazardous or explosive atmosphere area?
No. ZIPPKOOL garments are not intrinsically safe and are not rated for areas with flammable gases, vapors, or combustible dust.
Which battery does our EHS team need for site approval?
LI-PRO1U is ETL Certified by Intertek, an OSHA-recognized NRTL. If your site requires NRTL certification for battery-powered equipment, specify LI-PRO1U.
