Seafood Constant Temperature Machine

Keeping Seafood Alive and Fresh

Delin seafood constant temperature machines are purpose-built for seafood processing plants, aquaculture farms and hatcheries, restaurants, supermarkets, and live seafood storage. They hold water temperature at ±0.5°C accuracy between +5°C and +35°C, keeping shellfish, fish, and crustaceans alive and healthy through harvest, transport, and display.

From Harvest to Display

Seafood loses value the moment its temperature drifts. Fish and shellfish survive transport and storage only within a narrow temperature band, which is why constant temperature control matters from the moment product leaves the water through transport, processing, and market display. Delin machines maintain that band automatically, so live tanks stay healthy, chilled product stays at specification, and losses from temperature swings are eliminated.

Why Titanium Matters

The water side of a seafood system is corrosive — saltwater attacks copper and mild steel. That is why every Delin seafood unit uses a pure Grade 2 titanium heat exchanger. Titanium does not corrode in seawater, so the exchanger lasts for years and never contaminates the tank water with metal ions.

Engineered for the Seafood Industry

• Copeland / Emerson / Panasonic compressors tuned for continuous operation
• < 55 dB quiet operation for restaurant and market environments
• Anti-corrosion casing for humid, salt-laden air
• R410A low-GWP refrigerant
• Capacities from 2.8 kW to 85 kW (1–30 HP)
• Power supply options: 220V/50Hz/1Ph or 380V/50Hz/3Ph

Where Delin Seafood Machines Run

Delin seafood machines keep live tanks and cold rooms running across processing plants, fish markets, restaurants, and hatcheries. A compact unit of around 1 HP serves a single restaurant or market display tank, while farms and hatcheries step up to a large machine of up to 30 HP — or run several units in parallel — to hold ponds and holding tanks at a stable set-point. Power supply is matched to the destination: 220V/50Hz single phase or 380V/50Hz three phase, so installation is straightforward whether the project is in a city seafood market or a coastal aquaculture site.

Process, Hatchery, or Market — One Platform

The same machine platform serves processing plants chilling product lines at a controlled rate, hatcheries holding larvae and juvenile fish at a stable temperature, and restaurants and markets keeping display tanks alive. Each configuration is tuned for the duty: water flow, tank circuit, and set-point are matched to your operation, and our engineers provide installation and water-flow guidance with every machine.

Choose the Right Size

Sizing depends on tank volume, stocking density, ambient temperature, and target water temperature. Send us your tank dimensions and stocking plan — our engineers will calculate the heat load and recommend the right capacity, just as we do for aquaculture farms around the world. A single restaurant display tank may need only a 1 HP unit, while a large aquaculture farm or hatchery can require 30 HP.

Built for Round-the-Clock Duty

Seafood systems run continuously — a live-tank failure is measured in lost inventory, not lost hours. That is why Delin builds seafood machines for round-the-clock operation, with commercial-grade compressors, over-temperature protection, and an anti-corrosion casing that survives humid, salt-laden air. Standard models ship within 15-25 days and carry a 24-month warranty, and our technical team helps with installation, water flow, and set-point guidance for every project — with an MOQ of just 1 unit so you can start with one machine and scale as your operation grows.
