PRODUCT DESCRIPTION

Coil wound heat exchangers (CWHE), also called spiral wound heat exchangers (SWHE), were born at the

origin of cryogenic industry so that we cannot immagine cyogenic vaporization without this solution. More

than thousand coil-wound heat exchangers have been installed around the world for cryogenic as well as

for other industry fields.

Coil-wound heat exchangers are quite compact and very reliable for different application specially when

broad temperature are involved (vaporization). Its point of force remains the wide range of service pressure

that don’t still find any limitation since now. It is also suitable for single or multiphase flow.

TECNOCRYO DESIGN

Coils-wound in a vessel is one of the most robust and reliable solution for the vaporization of cryogenic

liquids such as Nitrogen, Oxygen and LNG. The coils are put together to form a bundle which is installed

inside a vessel where the hot liquid flows through. Hot water or water solutions (glycol-water) are usually

used as heat transfer fluid with different heat sources like electric power, steam etc.

Features

The coil-wound exchangers are:

- the best solution for discontinuous operations because of their heat capacity reservoir.

- the best solution for compensation of small temperature variation during the service

- immediately ready to give the full capacity

- easy controllable from reduced flow to full flow in both cold side and hot side

- designed for a lot of applications and can cover a broad range of heat capacity and flow rate

Because of their design, using tubes to form coils and bundle of coils, the coil-wound heat exchangers

are very robust since the pressure bearing is delegated to the cylindrical tubes, the easiest and best

pressure bearing components. Indeed the coils keep high the elastic capacity when shirinking is imposed

by temperature difference, hence the thermal stresses are reset and tube breaks are an unknown event

for these exchangers.

Benefits

TECNOCRYO QUALITY SYSTEM

TECNOCRYO relies on a High Quality System which completely

merges with the Engineering and Manufacturing facilities, pursuing

a strategy of continuous improvement within a moving market of

high technology.

Attention has been posed to the Standards and the relevant

product certifications, specially for the European Directives.

HYTC is a dedicated line for Hydrocarbon fluids, specially designed

for LNG or LCNG applications in the refuelling stations for

automotive field. The design and the use of reliable materials

makes the difference.
