Welcome to the most comprehensive range of plate type heat exchangers in the Industry.
Our Plate Type Heat Exchangers are proven to deliver designed performance in applications involving liquids, gases, steam and two-phase fluids.
VARALKA PHEs can be easily dismantled for inspection, cleaning, and maintenance. Another benefit is that they can be easily expanded or adapted to changed process conditions, by adding/reducing plates or sometimes replacing plates with different heat transfer characteristics.
The heating and cooling fluids pass through the channel created by corrugated heat transfer plates. The corrugations and numerous contact points create a turbulent flow which increases heat transfer coefficient manifold as compared to conventional shell and tube heat exchangers. The turbulent flow also provides a ‘self-cleaning effect’ in fouling duties.
By using exchanger plates with different physical characteristics, the exchangers can be adapted to a wide variety of applications.
Varalka PHEs are delivering satisfactory service in variety of applications:
- Sulphuric Acid Cooling
