Import 55 Qt (52l) Ultra Large Capacity Cooler Box — Buy in wholesale FOB from Supplier in China

The 55 QT (52L) Ultra Large Capacity Cooler Box from Ningbo Hengli Plastic Products Co,. Ltd. is a hard-shell insulated container built for extended cold retention in commercial and outdoor settings. Its external dimensions measure 59.1 by 44 by 47 cm, with internal cavity dimensions of 45.7 by 34.7 by 36.3 cm, yielding a 52-litre storage volume rated at 55 US quarts. The shell is constructed from LLDPE (linear low-density polyethylene) walls with PU foam insulation, a combination standard in roto-moulded coolers for thermal efficiency and impact resistance. Cold retention is rated at 5 days or more at 25 degrees Celsius with ice fully loaded, a figure that places it in the performance tier typical of premium marine-grade coolers.

The lid offers two design variants and an optional EVA foam pad on top for seating or kneeling comfort. Quick-flip nylon latches secure the closure, backed by a silicone gasket seal to minimise air exchange. Stainless steel hinges (SS#304 grade) and matching corner-mounted bottle openers resist corrosion in humid or salt-air environments. Removable carry handles allow breakdown for cleaning or compact stowage. A leak-proof drain plug permits water evacuation without tipping the unit. The gross weight is 12.5 kg and net weight 11 kg, which buyers should factor into freight calculations for containerised orders.

This cooler suits fishing charter operators, event catering companies, offshore marine crews, and wholesale distributors serving the camping and outdoor retail channel. The 20-foot GP container holds 210 units, 40-foot GP holds 436 units, and 40-foot HQ holds 510 units, giving buyers clear load-planning data. Each unit ships in an individual carton with OPP bag protection. Response rate and average response time data are not available, so buyers should establish direct contact to confirm current production schedules and any customisation requests such as colour runs or branded lid pads.

Ningbo Hengli Plastic Products Co,. Ltd. is located at No. 240 Yinhe Road, Chengdong Industry Zone, Daxu Town, Xiangshan, Ningbo, China, postal code 315000.
