HVN-400U - Class 2 Cooling Vest
The default for general construction. Ships complete with fans, battery, and cable.
Cooling gear for utility and energy crews
Long shifts at remote sites, hours from the nearest cooler — and no freezer for miles.
The heat problem on utility site
Utility and energy work happens where the infrastructure is, not where it's convenient. A crew servicing a substation, a pipeline right-of-way, or a remote well site can be an hour or more from the nearest town — let alone a store that sells ice.
Shifts run long by necessity: travel time eats into the day, and a callout or outage doesn't wait for a cooler break. Whatever cooling a crew brings has to survive the whole trip out, the full workday, and the trip back, with no chance to restock along the way.
What's specified for utility and energy work
High-visibility: Roadside and right-of-way work typically specifies ANSI/ISEA 107 Class 2 or Class 3, depending on proximity to traffic. Substation and remote-site work is often governed by internal utility PPE policy rather than a public traffic standard — check your company's requirement directly.
Arc flash and FR requirements: Much electrical utility work requires FR-rated clothing under arc-flash safety standards. ZIPPKOOL garments are not flame-resistant and do not meet FR or arc-flash requirements. Confirm with your safety team whether your specific task requires FR-rated PPE before specifying this product — for many electrical utility roles, it will.
Fall protection: Where elevated work on poles or towers requires a harness, ZIPPKOOL garments are compatible — the rear opening passes the dorsal D-ring through without affecting fit. This does not apply to work requiring FR-rated harness-compatible gear.
THE CASE FOR IT
Why fan-cooled works at a remote site
01
No freezer for miles
A battery charged the night before survives the drive out, the shift, and the drive back — no ice run required.
02
It covers the whole trip
LI-PRO1U runs 6–20 hours depending on output level, built for days that start and end with travel.
03
A spare battery beats a cooler
Lighter to carry, nothing to melt, easy to keep one charged as backup.
04
Works with harness requirements
For non-FR pole and tower work, the D-ring passthrough keeps the garment out of the way.
Where it doesn't belong
ZIPPKOOL isn't right for every job
Not flame-resistant.
For welding, cutting, hot work, or anywhere FR clothing is required, use FR-rated gear and a non-powered cooling option.
Not intrinsically safe.
Not rated for explosive atmospheres — flammable gases, vapors, or combustible dust.
Fans off near rotating machinery.
Running fans inflate the garment. Near shafts, conveyors, augers, or power take-offs, switch them off and keep the garment zipped.
Not a replacement for the basics.
Cooling garments supplement — they don't replace — hydration, rest, shade, and acclimatization.
FAQ
Questions we get from safety managers
The specification and compatibility questions that come up most.
Is this safe for electrical utility work?
Not for any task requiring FR-rated or arc-flash-rated clothing. ZIPPKOOL garments are not flame-resistant and do not meet arc-flash standards. Confirm your specific task's PPE requirement with your safety team before ordering.
Which battery is best for a long day at a remote site?
LI-PRO1U, for its longer runtime range — 6 to 20 hours depending on output level. Charge it the night before a trip with no return access.
What about gas or hazardous atmosphere sites?
ZIPPKOOL garments are not intrinsically safe and are not rated for areas with flammable gases, vapors, or combustible dust. Check with your safety team before use on any hazardous-atmosphere site.
