J-Series Cold-Chain Seafood Water Chiller
Ultra-Narrow R404A Constant-Temperature Chillers for Cold-Chain Seafood Display Cabinets
The Ultra-Narrow Cold-Chain Seafood Water Chiller
The J-Series is Delin's cold-chain seafood water chiller — an ultra-narrow constant-temperature machine built on R404A that fits the tight gap beside a cold-chain display cabinet. At just 308mm across, it slides into space other machines cannot use, while a pure Grade 2 titanium heat exchanger and Copeland compressor hold fish, shrimp, crab and shellfish at a precise ±0.5 °C. The cooling-first design spans 5200W to 8500W with auxiliary heating for cold-chain holding.
Technical Specifications
| Model | Power Supply | Power | Current | Cooling | Heating | Refrigerant | Water Flow |
|---|---|---|---|---|---|---|---|
| DL-E020R3A-J | 220V/50Hz/1Ph | 1030 W | 4.7 A | 5200 W | 1000 W | R404A | 2.0 m³/h |
| DL-E030R3A-J | 220V/50Hz/1Ph | 2030 W | 9.2 A | 8500 W | 2000 W | R404A | 3.0 m³/h |
The heating output is lower than the cooling output by design — the J-Series is a cooling-first cold-chain machine with auxiliary heating.
Cooling capacity is rated at 30 °C water temperature and 40 °C ambient air temperature.
Available refrigerants: R134A, R404A, R407C, R410A.

Built for Narrow Cold-Chain Installations
Cold-chain display cabinets leave little free floor space, so the J-Series trades footprint for height — an ultra-narrow 308mm body that tucks into the gap beside a cabinet or along a wall. Its R404A circuit is tuned for chilled holding, and the cooling-first design keeps a stable set-point through the sales day while the auxiliary heating covers seasonal demand.
