Product Details

The NL-630 630L is different from the rectangular fish tubs in the range. It uses a one-piece round rotomolded body made from food-grade LLDPE with PU insulation. A dedicated opening in the top allows mixing-paddle operation, and the side drainage structure supports draining after processing. The round interior is particularly suitable for fish, shrimp and seafood being mixed or held with ice water or other cooling media. Optional caster wheels, custom colors and logos are available according to the operating setup.

The round interior, top mixing-paddle opening and side drainage are the defining differences from a standard rectangular fish tub.

For industrial seafood handling, temporary storage, processing and sorting, dockside loading and cold-chain transport. The best application depends on the model capacity and body format.

Suitable for seafood processors, fishing ports, aquaculture operations, wholesalers and cold-chain projects. For volume orders, caster configuration, color, logo and other project requirements can be confirmed around the actual handling workflow.

OEM/ODM support is available with custom colors, logos and project-specific configurations, including optional caster wheels.

Industry knowledge

Ningbo Nelgreen Outdoor Products Co., Ltd. manufactures the NL630L shrimp seafood industry round insulated fish tub — a purpose-built rotomolded container for shrimp, fish and seafood processing, temporary storage and dockside handling. Unlike rectangular fish tubs, the NL-630 uses a one-piece round body with a dedicated top opening for mixing-paddle operation and a side drainage port. We supply this model as an OEM/ODM NL630L shrimp seafood industry round insulated fish tub Factory with custom colors, logos and optional caster wheels. The round interior and mixing opening make it a practical choice for seafood processors, fishing ports and cold-chain operators who need to hold or agitate product in ice water or brine.

Application Fit

The round interior of the NL-630 is designed for shrimp, fish and seafood that are mixed or held with ice water, brine or other cooling media. The dedicated top opening allows a mixing paddle to operate directly inside the tub, which is a common requirement in shrimp processing lines and seafood batch cooling. The side drainage port simplifies draining after processing or transport. Typical applications include:

  • Shrimp and seafood processing plants — mixing, cooling and temporary storage
  • Fishing port landings — dockside holding of catch before transport
  • Aquaculture operations — harvest collection and ice-slurry cooling
  • Cold-chain logistics — short-term refrigerated transport of seafood
  • Wholesale and distribution centers — sorting and staging

Construction and Materials

The NL-630 is rotomolded in one piece from food-grade LLDPE, which provides impact resistance and UV stability for repeated use in wet, salty environments. The high-density PU foam insulation layer maintains internal temperature for extended periods, reducing ice consumption during processing and transport. The one-piece construction eliminates weld lines and potential leak points. Optional caster wheels can be added for mobility in plants or on docks.

Configuration Options

We offer the following configuration choices for the NL-630:

  • Color: Custom colors available per project
  • Logo: Molded-in or pad-printed logo
  • Casters: Optional wheel set for plant or dock mobility
  • Drainage: Side drain as standard; alternate drain positions can be discussed
  • Mixing opening: Standard top opening for paddle operation

Quality Assurance and Compliance

Our manufacturing facility operates under quality control systems that comply with BSCI, ISO 9001, SGS, RoHS and FDA standards. Each NL-630 tub is inspected for dimensional accuracy, wall thickness uniformity, insulation integrity and surface finish before shipment. We also hold Alibaba Factory Verification. For specific compliance documentation required by your project, we can provide relevant certificates upon request.

Installation and Maintenance

The NL-630 requires no on-site assembly. Unpack, inspect, clean with mild detergent and place in the working area. If casters are ordered, they are factory-installed. Routine maintenance consists of washing with food-safe cleaning agents after each use and checking drain and caster hardware periodically. The rotomolded LLDPE body is resistant to corrosion and impact; no special storage conditions are needed.

Frequently Asked Questions

What is the difference between the NL-630 and a standard rectangular fish tub?

The NL-630 has a round interior, a dedicated top opening for mixing-paddle operation and a side drainage port. Rectangular tubs do not typically include these features, making the NL-630 more suitable for shrimp and seafood that require agitation or mixing with ice water.

Can the NL-630 be used for long-distance cold-chain transport?

Yes, the PU insulation provides effective thermal retention for short to medium transport durations. For extended cold-chain logistics, we recommend evaluating the specific temperature requirements and ice load. The NL-700 or NL-1000 models may also be considered for larger volumes.

What is the lead time for OEM/ODM orders with custom colors and logos?

Lead time depends on order quantity and customization complexity. Typically, 30–45 days after confirmation of all specifications. Contact us with your quantity and requirements for a precise schedule.

Is the NL-630 suitable for use with brine or salt water?

Yes, the food-grade LLDPE body is resistant to salt water, brine and common seafood processing chemicals. The one-piece rotomolded construction prevents leaks and is easy to clean.

Do you provide samples before mass production?

Yes, we can provide a pre-production sample for approval. Sample lead time and cost depend on whether standard or custom specifications are required. Contact our sales team to arrange.
