Alfa Laval ViscoLine™ is a range of highly efficient tubular heat exchanger types that incorporates corrugated tubes or other advanced profiles designed to increase turbulence in the flow of the media to be cooled. This substantially increases the overall heat transfer coefficient.

Introduction

The Viscoline™ CIP unit is the Alfa Laval tubular heat exchanger specially designed for the heating of water or CIP (NaOH, HNO3,…) solutions using steam or hot water as heating media.

Applications

The Viscoline™ CIP unit is ideal for:

  • Heating of water or CIP solutions by means of steam.
  • Processing low viscosity products, containing fibers and small particulates
  • General heating and cooling applications.

Benefits

  • Low maintenance and operating costs
  • High working pressures
  • High working temperatures
  • Easy to be inspected and cleaned
  • Easy to be assembled/disassembled.

Working principle

The heat exchanger is formed by a tube bundle (welded at both ends onto flat tube plates) inside a shell. Product medium flows inside the tubes of the bundle and the service medium between and around these tubes. This makes it compact and easy to install. All tubes are connected in parallel and in counter-current flow to the
service medium. The product tubes are corrugated. The service media shell is smooth. OBS! Vertical installation is recommended for steam to water heating in order to drain the condensate.
