Introduction :

Coil Gavin Heat Exchangers are constructed using circular layers of helically corrugated tubes placed inside a light compact shell. The fluid in each layer flows in the opposite direction to the layer surrounding it, producing a criss-cross pattern. The large number of closely packed tubes creates a significant heat transfer surface within a light compact shell. The alternate layers create a swift uniform heating of fluids increasing the total heat transfer coefficient. The corrugated tubes produce a turbulent flow where the desired feature of fluctuating velocities is achieved. This haphazard movement of fluid particles reduces deposit build up by performing a “scoop and lift” action. The connection locations and angle of entry is specially selected to reduce the probability of debris build-up.

Process Of Coil Gavin Heat Exchangers:

Coil Gavin heat exchangers are beverage cooler 40 comprises a tank or bath 52containing a liquid sub-zero coolant, and a heat exchanger 46 inside the tank which in use forms a bank of frozen, sub-zero coolant on the Coil Gavin heat exchanger. A beverage coil 54, in the form of a python, is immersed in the liquid coolant for routing and chilling a beverage. The liquid coolant also provides a reservoir for a coolant circuit 66,67 to a font to provide an ice tower. A divert valve is provided which can be controlled to divert hot refrigerant directly through the evaporator in the tank, to actively heat the bath so that a cleaning solution passed through the beverage coil does not freeze. By avoiding a passive defrost one can thereby speed up the cleaning cycle. In use, the beverage cooler chills a beverage and a font with a single tank rather than the conventional twin tanks.

Advantages Of Coil Gavin Heat Exchangers:

  1. High Performance: the unique coil arrangement has a large heat transfer area meaning high heat transfer coefficients.
  2. Compact and Lightweight: A closely packed tube makes our shell and coil exchangers compact and lightweight. Small footprint makes it easy to install where space is limited and hard to access.
  3. Low Maintenance Costs: corrugated tube design produces a high turbulent flow, which reduces deposit build-up and fouling. This means longer operating cycles between scheduled cleaning intervals.
  4. Low Installation Costs: vertical installation makes it ideal for hydric heating and cooling systems where space is an issue.
  5. Higher Temperature Differentials: helical design allows for higher temperatures and extreme temperature differentials without high stress levels and costly expansion joints.
  6. Flexible Designs: variety of model types and configurations allow shell and coil heat exchangers to be used with a wide range of pressures, temperatures, and flows.
  7. Low Pressure Drop:
  8. Easy selection based on sub-station space requirements and heat or cooling load.
  9. Units kept in stock for immediate delivery.

Applications Of Coil Gavin Heat Exchangers:

  1. Construction-the building roof plate, roof grille etc.
  2. Light industry-the home appliances with its shell, civil chimneys, kitchen appliances etc.
  3. Automobile-corrosion resistant parts of car etc.
  4. Farming livestock and fishing-food storage tools; frozen processing equipment of meat and aquatic products etc.
  5. Commerce-storage and transportation of materials, packaging equipment.
