Introduction
Mobile Refrigerated Trailer

The ZZKNOWN 4m Towable Refrigerated Trailer is the ultimate mobile cold chain solution for businesses on the move. Whether you are managing a busy catering event, transporting fresh farm produce, or running a mobile grocery store, this trailer provides reliable, precision-controlled cooling.

Featuring dual-temperature zones, it allows you to store frozen goods and chilled items simultaneously in one sleek, towable unit. Built with high-density insulation and a heavy-duty galvanized chassis, it’s designed to withstand highway speeds and rugged environments while keeping your inventory at the perfect temperature.

Key Product Highlights

1. Advanced Dual-Zone Cooling

Equipped with a high-efficiency monoblock refrigeration unit, the trailer supports a wide temperature range from -25°C for deep freezing to +10°C for chilling. The digital thermostat ensures stable, precise control for meat, seafood, dairy, or florals.

2. Heavy-Duty Thermal Retention

Our body panels use polyurethane foam sandwich technology with food-grade FRP interiors. This superior insulation reduces energy consumption by up to 30% and maintains internal temperatures even when the power is disconnected during short transits.

3. Road-Ready & Secure

Designed for safety, the trailer features a standard 50mm ball hitch and a robust dual-axle system. With integrated electric/mechanical braking and DOT-certified lighting, it is fully compliant for highway use in North America and Europe.

4. Commercial-Grade Access

The rear double-swing doors feature heavy-duty rubber seals to prevent thermal leakage. The interior is designed for easy cleaning and can be customized with adjustable shelving to maximize storage space.
