SRZ Finned Tube Heat Exchanger

SRZ Finned Tube Heat Exchanger

 SRZ finned tube heat exchanger is a kind of finned heat exchanger with steel fins wrapped around the steel tube. It adopts 21*2 seamless steel tube, winding steel fins outside diameter 51, sheet pitch 5/6/8 a total of 3 specifications, in order to get a better heat transfer effect, commonly used 5mm sheet pitch specifications, the unit heat transfer area of 0.866 square metres.

 SRZ finned tube heat exchanger consists of different number of surface tubes and tube arrangement, the standard series is for reference only. The actual demand is best tailored to different heat transfer requirements. At present, the exterior treatment of SRZ finned tube heat exchanger made of carbon steel is no longer galvanised, and the spraying of high-temperature-resistant silver powder paint is the commonly used means of surface anticorrosion.

  SRZ finned tube heat exchanger fins are cold winding process, featuring a large number of folds at the root of the fins, for the flow of air to play a role in disrupting the role of heat transfer coefficient of the finned tube can be improved. The disadvantage is that the resistance increases, and the folds are easy to accumulate dust and liquid.

 304 stainless steel or other stainless steel can be used to manufacture SRZ type finned tube heat exchanger, used for heating or cooling of clean air, for the anti-corrosion of the equipment also plays a positive role in the longer service life.

 SRZ type radiator is a kind of air heater used for heating air in steam system or hot water system, mainly used for hot air heating, air conditioning system and drying device air heating, is the main equipment in the hot air device, it is widely used in the current industrial and mining enterprises, the heating and ventilation system of each large building.

 Radiator can be used for the heat medium of steam or hot water. The working pressure of steam is 0.3-0.8MPa/square centimetre, and the temperature of hot water can be 130-70℃.

SRZ-type radiator is mainly by the air flow direction of the three rows of cross-arrangement of spiral finned tube bundle, the finned tube are 021 × 2mm seamless steel tube winding 15 × 0.5mm folded steel strip and become a helical, the pitch of the piece of 5mm-small "D", 6mm-"Z", 8mm - large "X", three kinds of thirty-eight specifications.

 SRZ-type radiator is characterised by compact structure, beautiful appearance, easy installation, convenient management, durable, it is not only suitable for centralised air-fed heating, but also suitable for local heating, or other purposes.

SRZ Type Numbering Method

Model No. - Ventilation cross-section length dimensions in metres rounded off × ventilation cross-section width dimensions in metres rounded off (piece spacing code)

For Example: the length of the ventilation section is 1505mm, the width is 1000, large, 5mm piece spacing, it is SRZ-15×10(D).
