Varitherm GEA Plate Heat Exchangers VT20/VT20P/VT20M OEM PHE Plates
and Gaskets In Food Industry
VT20/VT20P/VT20M Plate Heat Exchanger Construction
With Safetytherm, experts have succeeded in designing an extremely
reliable version of a conventional sealed plate heat exchanger. Two
extremely thin plates with welded inlet and outlet openings form a
small leakage gap within a double-wall plate. In the seldom event
of a plate crack occurring, this clever solution with special
leakage channels ensures that a mixture of a non-compatible media
is excluded and the leakage is visible.
The compact design and function of Safetytherm meets the high
standards. Our customers can be certain of one thing: Safetytherm
is a shining example of an effective and low-maintenance
double-plate solution which guarantees a high level of production
safety.

VT20/VT20P/VT20M 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.

VT20/VT20P/VT20M 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
PHE Troubleshooting
1. Insufficient Performance
| Fault | Cause | Remedy |
| Reduced heat transfer | Deposits on the HE plates | Clean HE plates - Cleaning HE plates while PHE is open and cleaning
HE plates while PHE is closed. |
| Operation, flow media etc. differing from the design case | Have PHE design with new operating data checked by M&C |
| Excessive pressure loss | Plugging of manifold flow gaps obstructs flow | Clean HE plates - Cleaning HE plates while PHE is open and cleaning
HE plates while PHE is closed. |
| Incorrect installation of HE plates obstructs flow | Check installation order by means of circuit diagram |
| Operation, flow media etc.differing from the design case | Have PHE design with new operating data checked by M&C |
2. Leaks
| Fault | Cause | Remedy |
| Leaks between the HE plates - flow media escape from the HE plate
pack | Incorrect tensioning dimension of PHE | Check correct tensioning dimension according to rating plate data |
| Excessive operating pressure | Check operating pressure according to rating plate data |
| Operating temperatures too high/too low | Check operating temperatures according to rating plate data |
| HE plate gaskets are not properly seated | Open the PHE and correct the seat of HE plate gaskets |
| HE plate gaskets are soiled | Open the PHE and clean the HE plate gaskets |
| HE plate gaskets either defective or hardened | Open the PHE and replace the HE plate gaskets |
| Leaks between HE plates and frames, reinforcement plates and
intermediate plates | Incorrectly seated HE plate and frame gaskets | Open the PHE and correct seat of plate and frame gaskets |
| HE plate and frame gaskets are soiled | Open the PHE and clean the HE plate and frame gaskets |
| HE plate and frame gaskets are defective | Open the PHE and replace the HE plate and frame gaskets |
| Leaks between frame connection and pipework | Excessive load of frame connection from pipework | Reduce connecting loads to permitted values |
| Gasket improperly seated | Slacken off frame connection and correct gasket seat |
| Dirty gasket | Slacken off frame connection and clean the gasket |
| Defective gasket | Slacken off frame connection and replace the gasket |
| Flange connection is not sufficiently tightened | Check gasket and retighten connection evenly if required |
| Damaged HE plates | Excessive tightening of HE plate pack (tensioning dimension below a
min.) | Replace defective HE plates |
| Damaged HE plates | Corrosion of HE plate material | Check design of PHE regarding flow media, contact M&C |
| Damaged HE plates at the beginning or at the end of the PHE | Incorrect earthing when welding on special connections to open
frame connecting pipes | Repalce defective HE plates |
