GEA KELVION Thermal Plate Heat Exchanger Seal Quick Easy Dismantling

GEA- KELVION VT04 CD-16 Thermal Plate Heat Exchanger Plates&Gaskets

Plate Heat Exchanger Introduction

In the PHE the plates create a frame where the plates are pressed with headers and tie bars, and the seal is guaranteed by gaskets. Gaskets, in addition to their sealing effect, serve to direct the flow of the fluids, and are placed along the grooves at the edges of the plates.

The maximum temperatures used for sealing heat exchangers are between 80℃ and 200℃ while pressures can reach 25 bar.

Gaskets are available in various types of butyl or silicone rubber.

The main characteristics of these types of heat exchangers are:

- quick and easy dismantling for cleaning and control operations

- adaptation to variable operating conditions by adding or removing heat plates to modify the installed thermal flow

- any fluid leaks due to non-perfect sealing of the gaskets do not contaminate the other fluid but are directed away

- materials that are poorly adapted to soldering, such as titanium, may be used

- the gaskets limit the maximum pressure and temperature values

- potentially high costs due to the design of moulds, presses and all the production process

- high cost of the gaskets

VT04 Gasketed Plate Heat Exchanger - Varitherm Systematic Product Variety

Whether in heating or cooling of liquids containing particles of up to 2mm in size, in condensing vapours or in gas cooling and gas dehumidifying in special cases- Varitherm plate heat exchangers offer a convincing solution with the widest range of possible applications.

The Varitherm Series has two convincing arguments in its favour. Firstly there is a wide range of materials available, including 1.40301/AISI304, nickel-based alloy, Incolloy, nickel, tantalum and titanium. Secondly it comes with an individual plate pack that can be easily expanded to meet your future needs. And this makes the Varitherm Series the optimum economic solution for just about every application.

Gentle product handling

The gentle treatment of products caused by the soft corrugation makes the Varitherm the obvious choice for the foodstuffs industry.

PHE Type of Safetherm and Varitherm

VT04 Frame

PHEs are available in various application-specific frame versions. The basic versions are the C and B designs, with the B design being used above all for longer plate packs.Variants of these designs are marked by further abbreviations.

Special Stianless steel versions are employed in foodstuff and pharmaceutical applications and may include intermediate plates for separating the individual sections.

Some frames are equipped with height-adjustable bases

How to Provide Plate Heat Exchanger Maintenance?

Plate heat exchanger maintenance is provided through two distinct methods:

• Clean in place (CIP) on-site maintenance.
• Authorized cleaning facilities off-site maintenance.

The basic difference between these two methods is not how, but where and who performs the maintenance. CIP is performed in the manufacturing plant for quick recovery and continued equipment use, and it usually is performed by the person in charge of maintenance. Utilizing and authorized cleaning facility for maintenance requires removing the equipment and shipping it to a facility outside the plant where certified maintenance personnel service the plate heat exchanger. A closer look at each method will help shel light on which is best.

CIP Maintenance.Because of the advantages of quick turmarounds in a maintenance cycle, CIP is an attractive maintenance method. It is faster, more convenient and simple. It is also a preferred cleaning method when especially corrosive liquids are being processed. Typically, a CIP operation would be as follows:

• The plate heat exchanger unit is turned off.
• All fluids are drained from the unit. Single-pass units are self-draining. Multi-pass units may require special drain holes.
• The preselected cleaning solution is circulated through the unit in a bottom-to-top flow to totally flood the unit and prevent channeling. When it is determined that the solution is no longer reacting with the substances inside the unit, the cleaning is complete.
• The unit is drained of the cleaning solution and, if necessary, rinsed with water and put back online.

Authorized Cleaning Facilities. The disadvantages of the authorized cleaning facilities tend to be measured by the up-front cost and rarely for the real advantages achieved.

At an authorized cleaning facility, each plate is logged and visually inspected to determine if it merits reconditioning. The client is informed if any plate is underviceable and why. The facility cross-checks its databased to conirm the plate heat exchanger's original specifications and then conducts a close visual inspection of gaskets and contact points on the remaining plates to determine if there is any erosion or apparent change from the original specification. Then the precise cleaning and treatment process required is determined.

Plates are pressure-washed, rinsed and subjected to either hot caustic stripping and/or a manual procedure for gasket and scale removal. They are subjected to immersion in a variety of acids compatible with the plate material to remove the balance of any foulants. Cleaned plates are fully visually inspected and a 10 percent sampling of plates are dye-penetrant tested. Each tested plate is sprayed with dye and inspected under eltraviolet light to locate any pin-hole leaks or cracks. Following this procedure, plates again are pressure-washed and rinsed to remove all traces of the dye.

Plates are then re-gasketed with an OEM-spec gasket adhesive that eases field repair should it be required. Plates receive a thorough inspection before being packed and shipped. Units are hydrostatically tested prior to shipment.

Plate Heat Exchanger Intended Use

The PHE is a component intended for permanent installation in a plant or a machine. It serves for heat transmission from the heat-releasing flow medium to a heat-accepting flow medium.

We recommend that you put the PHE into operation only after checking if the plant or machine into which the PHE has been integrated meets the appli- cable national regulations, safety rules and standards.

The PHE is a technical equipment and not intended for private use. It is basi- cally designed for mostly stationary use.

The PHE was designed and built specifically for the operating conditions you have specified. The operating conditions are documented in the technical documentation:

• Min./max. allowed pressure
• Min./max. allowed temperature
• Flow rates
• Type and composition of flow media
• Additional loads if allowed
• Deviating from these allowable operating conditions will void the warranty and the operating permit. The same applies to unauthorized essential modifications on the PHE.
• Please contact your Kelvion Sales Office for verifying such requirements and the possibly required modifications.

The intended use also includes:

• Compliance with the present operating instructions and the technical documentation included in the delivery;
• That the plate heat exchanger is in technically flawless condition, i.e. it shows no apparent defects, e.g. loose or missing tensioning bolts, leaks due to defective HE plates and/or frame gaskets.
• Observing the national and international laws, decrees, regulations, guidelines and other rules, e.g. occupational safety and accident preven- tion regulations, applicable at the place of installation even if these are not listed in the present operating instructions.
