What Makes An Aqua Systems Evaporator Work So Well?
A High Performance Heat Exchanger Will Substantially Improve Heat Pump Performance

1) Water enters the upper two tubes. As it passes through the tubes, turbulence of the water is maintained, even at low water flow, due to the internal rifling of the tubing.
2) Refrigerant liquid enters via the lower refrigerant tube and is forced to follow a long spiral flow path. This flowpath is created by the tight tolerance between the copper tubing and the steel side walls.
3) The enhanced surface of the copper tubing, 3.7 times that of smooth tubing, releases heat from the water side. The spiral and axial refrigerant flow causes rapid evaporation of the refrigerant, resulting in a very low pressure drop on the refrigerant side and no oil trapping.
4) As the liquid refrigerant absorbs heat from the water it begins to boil off, exiting the heat exchanger as a gas.
5) The water tubes cross over at the mid point of the heat exchanger. The outside tube becomes the inside and the inside becomes the outside tube. This results in two tubes exactly the same length, with equal pressure drop and equal heat exchange.
6) The cooled water exits the two lower water tubes.

 

Benefits of Using Aqua Systems Condensers in Water Cooled Air Conditioners. Models 1.5 Tons to 57 Tons.

AQUA SYSTEMS refrigerant to water heat exchangers incorporate the latest in refrigerant heat exchanger technology. The compact size and the high level of heat exchange efficiency are achieved by the Aqua Systems unique heat exchange tube geometry.

The enhanced surface of the copper or cupro nickel tube provides surface extension of 3.7 times that of smooth tubing. The conical, co-axial design of the water coils and the internal rifling ensures that water turbulence is maintained even at low water flow rates.

On the refrigerant side, the close tolerances between the water coils and the condenser shell, result in the extraordinary heat exchange performance during condenser duty on the cooling cycle. As they are designed to also suit reversible applications, the unique design provides a high level of performance when the heat exchanger is used as a liquid chiller.

Some of the features which make the Aqua Systems heat exchanger the best condenser choice are as follows:

1) Close approach temperature between the Refrigerant Condensing Temperature and the Leaving Water Temperature reduces the volume of condenser water to be circulated. Reduces the size of condenser water pipes and circulating pumps.
2) Efficient Liquid Refrigerant Sub Cooling as the leaving liquid is subcooled by the entering water due to the counterflow design enhancing system efficiency.
3) Drainable water tubes due to the spiral design allows easy draining of the water tubes for freeze cleaning.
4) Freeze cleaning of the water tubes after draining, allows rapid condenser cleaning with minimum downtime and no mess. Eliminates the use of chemicals.
5) NO oil trapping as a result of the close tolerances in the refrigerant path.
6) Improves heat pump performance with high BTU output at low water temperatures.
7) Low water side pressure drops reduces pump size and operating costs.
8) Continuous water coils with no internal joints has less chance of leaks.
9) Compact size convenient cylindrical shape is easy to insulate.
10) Reliable operation, as all AQUA SYSTEMS heat exchangers are tested to 530 psi after manufacture.
11) UL® listed. Complies with Australian Standard 2971-1987 Serially Produced Pressure Vessels.
12) All models available from stock to meet those urgent orders or repairs.

 

Aqua Systems the Best Marine Water Cooled Condensers for Refrigeration or Air Conditioning Installations.

Compact and Low Fouling.

AQUA SYSTEMS "CN" Series marine refrigerant condensers incorporate the latest in refrigerant heat exchanger technology. The compact size and the high level of heat exchange efficiency are achieved by the Aqua Systems unique heat exchange tube geometry.

The enhanced surface of the cupro nickel tube provides surface extension of 3.7 times that of smooth tubing. The conical, co-axial design of the water coils and the internal rifling ensures that water turbulence is maintained even at low water flow rates.

Low Fouling due to the elimination of low velocity spots and the allowable increase in leaving water temperature reduces spot scaling and inhibits fouling due to mollusks.

Features which make the Aqua Systems heat exchangers the best MARINE condenser choice are as follows:
1) Close approach temperature between the Refrigerant Condensing Temperature and the Leaving Water Temperature reduces the volume of condenser water to be circulated. Reduces the size of condenser water pipes and circulating pumps.
2) Efficient Liquid Refrigerant Sub Cooling as the leaving liquid is subcooled by the entering water due to the counterflow design enhancing system efficiency.
3) Drainable water tubes due to the spiral design allows easy draining of the water tubes for freeze cleaning.
4) Freeze cleaning of the water tubes after draining allows rapid condenser cleaning with minimum downtime and no mess. Condenser can be cleaned in under 1 hour.
5) NO oil trapping as a result of the close tolerances in the refrigerant path.
6) Vertical design assures constant liquid output even in rough seas.
7) Low water side pressure drops reduces pump size and operating costs.
8) Continuous water coils with no internal joints or troublesome tube plates.
9) Compact size convenient cylindrical shape is easy to install.
10) UL® listed. Complies with Australian Standard 2971-1987 Serially Produced Pressure Vessels.
11) All models available from stock to meet those urgent orders or repairs.
