Admiralty brass tube for cooler is the admiralty brass tube (consisted of Copper, Zinc and Tin) used in evaporative cooler, which is a device that cools air through the evaporation of water. Evaporative cooling differs from typical air conditioning systems using vapor-compression or absorption refrigeration cycles. Evaporative cooling uses the fact that water will absorb a relatively large amount of heat in order to evaporate, (that is, it has a large enthalpy of vaporization).

Alloy and production standard:

C44300 (ASTM B111 or ASME SB111)

CuZn28Sn1As (EN12451 or EN12449)

CuZn28Sn1 (DIN)

CZ111 (BS British Standard)

C4430 (JIS Japanese Industrial Standards)

Chemical composition:

70.0≤Cu≤73.0 ; 0.8≤Sn≤1.2;

Zn Rem; 0.02≤As≤0.06

Dimension/size:

Outside diameter range : 5mm~110mm

Wall thickness range : 0.3mm~10mm

Maximum length: 24 meters

Field of application:

Admiralty brass tube for cooler is generally intended for evaporative cooler, including but not limited to swamp cooler, swamp box, desert cooler and wet air cooler and so on. Evaporative coolers lower the temperature of air using the principle of evaporative cooling, unlike typical air conditioning systems which use vapor-compression refrigeration or absorption refrigerator.

Production features:

Our products have excellent conductivity, heat transfer properties, outstanding corrosion resistance, high pressure resistance, high temperature resistance, frost resistance, good mechanical properties, pressure processing and welding performance.
