D&D DC750 Refrigerated Chiller

D-D have been supplying chillers for several years that provide high efficiency, proven reliability and economy with respect to both running and initial purchase costs.

The new DC750 refrigerated chiller is compact enough to fit in most cabinets but has a cooling capacity of 750W making ideal for aquariums of 300 lts at a 10°C temperature drop to 600 lts with a 5°C temperature drop.

Features
Microcomputer control – for accuracy and ease of use with a built in temperature memory system in the case of a power failure. Integral over temperature cut off.
Pure TITANIUM heat exchanger /evaporator – for it’s extreme anti corrosion properties in a saltwater environment.
Low running noise
High efficiency, latest generation cooler – for low running costs.
Superior quality condenser – for reliability and low noise.
Robust metal chassis – for strength and anti vibration properties
Contemporary housing design – to fit with most decors.

Performance
The performance chart below shows the cooling curve for the DC750 working on an aquarium of 300 litres of water which starts at a water temperature of 28°C. You can see the drop in temperature of the aquarium hour by hour as it is recirculated through the cooler.

The ambient air temperature in the room remains at 30°C throughout the test.

The chart shows that the temperature of the water is reduced by 10°C in a period of 12 hours.

Internal fuse – T start T6.3A/250V or 10A/250V if T start type fuse is not available

The mains plug is also protected by a 13 amp fuse

Note that no heat from lighting or other equipment is added to the water mass during the test.
