Shell & Tube Heat Exchanger - Tube heat exchanger

This leaflet describes heat exchangers which are intended for heating or cooling process fluids, they are for example suitable for closed circuit cooling of electrical equipment using demineralised water and for cooling water soluble oil solutions in quenching tanks. 

The shell side usually contains the process fluid and the tube side water from the town mains or a cooling tower or an ethylene glycol solution from a chiller unit. In certain circumstances this flow arrangement can be reversed, but please consult us first.

The heat exchanger designation consists of a type number followed by a drawing number which is marked on the nameplate. This five figure drawing number alters according to duty and materials. Standard materials are cupro-nickel tubes, cast aluminium shell and cast iron end covers. In addition we have some heat exchangers with a copper alloy shell and others which also have bronze end covers. They are available with single or three pass end covers according to the duty. The single pass flow arrangement should be used when the tubeside flow is much larger than the shellside flow. Normally when the two flow rates are similar three pass flow on the tubeside will give best performance. To specify materials and configuration alter the five figure section of the designation as shown in Table 1.
