Varitherm GEA Plate Heat Exchangers VT20 OEM PHE Plates Gaskets For Food Industry

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
