Whiteleg shrimp (Litopenaeus vannamei) grow fastest at 28–32 °C, stop feeding below 18 °C and die below ~9 °C. Here is how precise temperature control in high-density farming lifts survival, growth and feed conversion — and how to size an aquaculture chiller for it.
From depuration tanks to the cargo hold, live green-lipped mussels, Pacific oysters and rock lobsters survive only inside a narrow temperature band. Here's how ±0.5 °C seawater cooling protects survival through holding, depuration and pre-air-freight chilling — and how to size the right chiller.
Buying a 5HP water chiller? Learn the five tell-tale signs of a 3HP unit relabeled as 5HP — fan count, cabinet height, compressor displacement and electrical specs — before you pay.
Planning an 18–21 kW seawater chiller for lobster tanks or aquaculture? Learn why 3-phase power is safer, more reliable, and more cost-effective than single-phase.
Standard commercial air-cooled chiller or purpose-built water-cooled chiller — which one protects a large marine aquarium? A plain-language comparison of cost, corrosion, footprint and the parallel sizing a 135-tonne tank actually needs.
Six clips of raw factory footage — from assembly and performance testing to export packing — showing how Delin builds chillers, and why in-house production and testing matter when you source from China.
Land-based RAS farming of king crab and snow crab depends on rock-solid water temperature between 2 °C and 6 °C. Here is why a high-capacity, titanium-exchanger chiller is the difference between a profitable facility and lost stock.
A small, low-noise water chiller does far more than keep an aquarium comfortable — it holds ornamental fish through hot summers, times broodstock spawning by temperature, and cools delicate seahorse breeding tanks.
Why New Zealand Pāua (abalone) farms need precision titanium chillers for land-based RAS and pre-export live holding — and how ±0.5 °C seawater cooling protects survival, growth and export quality.
The chiller is the easy part — the plumbing is what decides whether it works. Why a titanium barrel rated at 3 m³/h cannot be fed by a 12 m³/h display loop, how to size pipe by velocity, and the commissioning checks that catch the mistake before the fish do.
Mushroom rooms are latent-load dominated: the coil is a dehumidifier before it is a cooler. How to size a chilled water plant from compost tonnage, why the compressor runs in January, and what to specify for a washdown environment.
Platysternon megacephalum needs 19–23 °C water, and it needs that temperature to move on a seasonal cycle. Where the chiller belongs in an RAS loop, why cold water slows the biofilter, and what to specify for a copper-free chilled-water circuit.
How hydrocooling removes field heat from leafy greens, broccoli, celery and carrots far faster than forced-air cooling, the three system configurations, target pulp temperatures by crop, and how to size the chiller and circulation loop.
How a centralised chilled-water plant serves the five cooling duties in an agricultural processing centre — hydrocooling, wash water, process machinery, cold store assist and packaging lines — and what to specify for 24/7 harvest-season duty.
Why cooling the root zone instead of the whole greenhouse air volume cuts cooling energy by 40–70%, how a root zone cooling system is plumbed, and what to specify for hydroponic, NFT and vertical farms.
Why nutrient solution above 22 °C triggers dissolved-oxygen collapse and Pythium root rot, the optimal root-zone temperature by crop, and how to size a commercial hydroponic water chiller for DWC, NFT and vertical farms.
Why a Saudi rooftop water tank heats past 50 °C in summer, why a standard chiller cannot fix it, and how the DL-T3 high-ambient (T3-rated) process chiller range cools 1,500 L and 3,000 L rooftop tanks to 25 °C in about 9 hours at 50 °C ambient.
How to cool the large, round-the-clock aquarium displays found in hotel lobbies, shopping malls, themed restaurants and ocean-themed commercial spaces — and how to choose the chiller by the space it has to fit.
Why fish, shrimp, crab and bivalve hatcheries and nursery tanks need dedicated constant-temperature cooling — and how a Delin DL-E chiller holds ±0.5°C with a pure titanium heat exchanger.
Why high-end saltwater fish tanks and coral reef systems need a seawater-grade chiller — and how Delin's pure-titanium DL-E machine keeps corals, invertebrates and marine fish at a stable temperature, quietly, 24/7.
A behind-the-scenes look at how Delin builds pure titanium (TA1/TA2) evaporators and heat exchangers in our own workshop — from coil forming and TIG welding to pressure testing and inspection, and why real in-house manufacturing matters when you source from China.
How Delin configured a 5 HP pure-titanium chiller to cool a 3,000 L potable water tank from 50–60 °C down to 25–30 °C in outdoor Saudi Arabia — the heat-load math, high-ambient design choices, and why Grade 2 titanium is non-negotiable.
How to choose and size a constant-temperature chiller for marine reef tanks, koi ponds, and ornamental fish farms — heat-load math, Delin's pure titanium heat exchanger technology, and practical installation tips.
How we sized a 5HP titanium-heat-exchanger chiller to cool a 1200-gallon aeroponic nutrient reservoir from 28°C to below 22°C — the heat-load math, expected cooling time, and operational tips.
How to size and control a seawater chiller for shrimp hatchery and nursery tanks: 5 m³ per tank, 30–35 ppt salinity, 26–30°C to 20–24°C in under 1.5–2 hours, and 200,000–240,000 BTU/hr of installed duty.
