D-D have been looking at refrigerant coolers for a number of years and with the new DC-2200 we now offer the very latest generation models giving high efficiency, reliability and economy with respect to both running and initial purchase costs.

The new DC-2200 refrigerated cooler is compact enough to fit in most cabinets but has a cooling capacity of 2200W making ideal for aquariums of 1200 lts at a 10°C temperature drop to 2100lt 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 - (quieter than an equivalent domestic refrigerator).
• 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 chart

The performance chart below shows the cooling curve for the DC-2200 working on an aquarium of 1000 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.

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