Heat Relief That Shows Up on a Trailer
Shade tents help, but they do not bring body temperature down on a 105 degree afternoon. The On-Site Hydration Services cooling trailer gives people a sealed, air-conditioned room to sit, cool off and recover before heading back out.
A 24,000 BTU mini-split keeps the room cold, tinted windows cut the sun, and bench seating with charging ports lets a whole rotation rest at once. Add a water station outside the door and the cooling station is complete.

What Customers Say About the Cooling Trailer
The cooling trailer became the center of our heat plan. Workers rotated in, cooled down and went back out feeling better. Paired with the water station, it covered everything our safety team asked for.
Carmen C.Safety manager, road constructionAthletes and medical staff had a real cool room between heats. The A/C stayed strong all afternoon. The team picked up every time we called.
Patrick R.Race directorOur building ran hot during a summer heat wave. The cooling trailer gave our shift a place to recover on breaks. Easy to set up, easy to work with, and the crew loved it.

Why It Works as a Cooling Station
Strong A/C
A 24,000 BTU mini-split cools the full 24 ft room, and the same unit heats it when nights turn cold.
Tinted Windows
Four oversized tinted windows let in daylight while keeping the afternoon sun off the people inside.
Pairs With Water
Set it beside an On-Site Hydration Services water station for shade, cool air and cold water in one place.
One Power Cord
A dedicated 240V 50A shore cord runs everything from site power or a generator.

Cooling trailers and heat illness prevention
Heat illness plans usually call for water, rest and shade. A cooling trailer covers the rest and shade part with real air conditioning, and an On-Site Hydration Services water station covers the water part right outside.
Placement and power
Plan a level spot for a 24 ft trailer near where people work or gather, with access to both entry doors. Power comes from one dedicated 240V 50A shore cord on site power or a generator.
How many people it serves
Bench seating runs the length of the room, so a rotation of workers can cool off together. Larger sites often schedule staggered breaks or book more than one trailer.
Same trailer, break room use
On longer projects the cooling trailer doubles as a lunchroom and site office. See break room trailer rentals for that setup.
