Smart Cooling for Safer Trailers

Inside a trailer on a summer day, temperatures can soar past 150°F, turning loading and unloading into a punishing, dangerous task for employees. Patterson’s Smart Evaporative Truck Cooler (SETC) changes that. By spraying a fine mist of water across the trailer’s roof, the system uses natural evaporation to draw away heat, dramatically lowering interior temperatures and creating a safer, more comfortable work environment.

This all-in-one system is engineered with precision sensors and rugged components to deliver reliable performance day in and day out. It automatically detects truck presence, monitors roof temperature, and sprays only as needed to achieve maximum cooling efficiency. With easy 24V AC power and water supply connections, the SETC is simple to integrate into existing dock operations.

The result? Smarter cooling, safer employees, and a system built to withstand the rigors of industrial environments.

SETC + HVTC = The Ultimate Cooling Solution

When it comes to battling extreme trailer heat, no single system works harder than Patterson’s. Pairing the Smart Evaporative Truck Cooler (SETC) with our proven High Velocity Truck Cooler (HVTC) delivers a one-two punch against stifling conditions.

The SETC attacks the problem at the source, spraying a fine mist across the trailer roof to drop surface temperatures fast. Meanwhile, the HVTC takes over inside, driving a surge of high-velocity air the full 53 feet of the trailer, pushing out trapped heat and replacing it with cooler, fresher air.

Together, these systems create a cooled, air-flushed trailer environment that keeps workers safer, speeds up loading and unloading, and protects your products from heat-related risks. It’s a smart, scalable solution engineered for today’s toughest distribution and fulfillment centers.

SETC & HVTC: Complete Trailer Cooling

Cool the Roof

SETC sprays the trailer roof with a fine mist to rapidly pull heat from the surface, stopping extreme temperatures before they radiate inside.

Flush the Heat

HVTC drives powerful, high-velocity airflow the full 53 feet of the trailer, sweeping trapped hot air out while pulling in cooler, fresher air.

Protect Workers

Together, these systems create a safer, more comfortable environment, reducing heat stress and fatigue during tough loading and unloading shifts.

Boost Productivity

By cooling conditions and cutting down heat-related slowdowns, trailers turn faster, employees stay sharper, and operations keep moving efficiently.
