Coolers

* Plain Tube-

• Easy to clean
• Very effective due to large surface area of large number small diameter tubes
  
• Plugging of failed tube allos cooler to continue in service with little loss in efficiency
  
• Must allow for thermal expansion by having one tube plate floating

* 'U' tube-

• Suitable for higher pressures than plain tube
• Self compensating for thermal expansion
  
• Efficent due to large nomber small diameter tubes
  
• More expensive than plain tube and diificult to clean

* Coil tube

• Self compensating for expansion
• Suitable for high pressures
  
• Difficult to clean
  
• Inefficicent due to large tube diameter
  
• Not easy to plug
  
• Expensive
