Cooling solutions for safety managers who need something crews will actually use

Chiller Body gives safety managers a simple cooling layer that fits inside existing hats and hard hats. It is easy to brief, easy to rotate from the cooler, and practical for pilot programs that need visible adoption on hot days.

Fits inside existing headwear

Workers do not need to change uniforms or adopt powered equipment. Inserts fit inside many hats, hard hats, and helmets already in use.

Easy to brief and document

The workflow is simple: freeze, insert, rotate from the cooler. That makes training and field adoption easier than more complicated cooling systems.

Scales from pilot to rollout

Most teams start with a pilot group and then expand to broader deployment once supervisors confirm comfort, usage, and rotation needs.

A rollout path that works on real jobsites

The fastest way to lose a heat initiative is to make the field process too complicated. Chiller Body works because the workflow stays simple and the equipment lives close to the people who need it. There are no batteries, no charging stations, and no new device training requirements.

For many teams, the right play is to pair inserts with the supervisor cooler, issue two per worker, and document usage inside your existing heat guidance. That turns cooling into something operational instead of optional.

Suggested implementation sequence

1

Identify the hottest roles, shifts, tasks, or work zones first.

2

Issue at least two inserts per pilot user so rotation is possible.

3

Keep backups in an insulated cooler near the work area or supervisor station.

4

Pair the inserts with the hydration, shade, and rest-break guidance you already enforce.

5

Collect supervisor feedback after the first high-heat week and adjust quantity planning from there.

Pilot groups

Start with exposed crews, route leads, or event teams where heat complaints and fatigue show up first.

Program support

Fold inserts into existing hydration, shade, and break guidance instead of creating a separate safety workflow.

Fast adoption

The easiest cooling program to scale is the one workers can explain to each other in under thirty seconds.

Will Chiller Body affect hard hat fit or certification?

The insert is designed to sit inside existing headwear without electronics or structural modification. Teams should still confirm fit and comfort with their own PPE policies, but the goal is to work within the gear workers already wear.

How should a safety manager pilot the product?

Start with the hottest crew or the roles with the highest direct-sun exposure. Provide a cooler, issue at least two inserts per user, and gather supervisor feedback on comfort, adoption, and rotation timing.

What does a typical deployment look like?

A common setup is two inserts per worker plus extras in the supervisor cooler. That gives teams a live insert and a backup insert without creating complicated charging or maintenance needs.

Is this only for construction?

No. Safety managers use cooling inserts across construction, utilities, landscaping, warehousing, outdoor events, recreation operations, and other heat-exposed environments.

Are there age or supervision restrictions for use?

Yes. Chiller Body is designed for adult use and is not recommended for workers under 14 without direct adult supervision, and is not intended for anyone under 8 under any circumstances. Safety managers planning crews that include apprentices, summer hires, or youth workers should review the full guidance on our Safety Information page and incorporate it into onboarding.
