Heating and cooling in electroplating and surface engineering

The highest chemical resistance with low space requirements

SYNOTHERM® heat exchangers allow for use in heat exchange loop systems through which a hot liquid (such as hot water, steam, hot oil) is passed through the panel. Heat energy from the hot liquid then transfers through the internal surface of the panel into the process solution tank. The spot-welded, perforated design creates turbulence through the channels, ensuring heated liquid molecules all touch with the internal surfaces of the panel therefore increasing heat exchange efficiency. Heat losses during the production process are compensated. A process generated heat input (e.g., from ambient heat, rectifier, or an exothermic reaction), can be compensated with the aid of heat exchangers by passing a cold liquid (e.g. cold water, glycol) through the panel.

SYNOTHERM® PFA-coated plate heat exchangers exhibit a metallic base build. The compact, lightweight and pressure-resistant design of the metallic base enables a long service life and high operational reliability of the heat exchanger.

In a multi-stage coating process, a fluoropolymer coating is applied to the metallic base build.

Zero porosity of the coating is verified by conducting a 100% high voltage test.

Thanks to the PFA-coating, SYNOTHERM® PFA-coated plate heat exchangers feature excellent chemical resistance and anti-adhesion properties, thus fulfilling two key requirements for use in chemical apparatus engineering. They are suitable for tempering highly acidic process liquids.

The anti-adhesive fluoropolymer coating ensures homogeneous heat transfer in conditions where incrustations, build-ups and deposits restrict the heat transfer capacity of heat exchangers. Fluoropolymers have significantly better heat transfer properties than other coating materials and plastic heat exchanger. The incrustation tendency from media that cause heavy incrustation, such as zinc phosphates, is reduced considerably.

Easy cleaning and extended maintenance intervals reduce maintenance costs and ensure the availability of your plant in the long term. Falling parts or sediments cannot deposit on or get caught in the heat exchanger body.

The coated plate heat exchangers have a high surface density. This means that a large heat exchanger surface area (in m²) can be provided in relation to the required construction volume (in m³).

The total installation depth (see image) is 61 mm (11 mm heat exchanger body + 50 mm spacer to tank wall). The space saving reduces the size and cost requirement for tanks. More space is available for other components in the tank or plant (pumps, rectifiers, barrels etc.).

Plate Heat Exchanger SYNOTHERM® as as multiple plate version

Our plate heat exchangers SYNOTHERM ® can also be designed as multiple plates. A multiple plate consists of several individual plates.

A specially designed collector connects the flow and return of the individual plates. Thus, only one connection to the flow and return is necessary in each case. In addition, the heat exchange medium is evenly distributed to the individual plates so that each single plate can deliver the same power.
If there is insufficient space in the tank (length and height), the required heat exchanger capacity can be achieved with the aid of the multi-plate version.

For cleaning and maintenance, only one device must be removed in the multi-plate version. The space between the individual plates can be easily and quickly cleaned with a steam jet or a high-pressure cleaner.

Successful certification according to DIN EN ISO 3834-3

We have been tested as a manufacturer in accordance with DIN EN ISO 3834-3 and have demonstrated all the welding requirements for the manufacture of pressure equipment in accordance with the Pressure Equipment Directive 2014/68/EU.

Our production facilities ensure appropriate and state-of-the-art production and testing of the heat exchangers SYNOTHERM ®. The quality assurance processes ensure the processing and testing of the materials according to the technical rules.

For the inspection by TÜV SÜD Industrie GmbH, welding instructions were created and audited for all welding processes. This ensures error-free and reproducible welding processes.
Our welding specialists are certified according to EN ISO 9606.
The welds of your plate heat exchangers SYNOTHERM® meet the highest international quality requirements.

Successful certification according to Pressure Eqipment Directive 2014/68/EU

Our SYNOTHERM® plate heat exchangers are now also certified according to the latest criteria of the Pressure Equipment Directive 2014/EU/68: TÜV SÜD Industrie Service GmbH has tested our plate heat exchangers in accordance with Directive 2014/68/EU. All processes – from design and configuration through production to final pressure test and final inspection – were audited in accordance with the requirements of Directive 2014/EU/68 in conjunction with AD-2000.

The Pressure Equipment Directive 2014/68/EU requires the conduct of a risk analysis. In addition, measures have been defined to eliminate or reduce the risks and safeguards against non-remediable hazards.
In conjunction with the risk analysis, the installation and operating instructions have been revised and adapted to Directive 2014/68/EU and AD 2000. Each product is delivered with a manual.
Before delivery, each product is subjected to a pressure and leak test. A pressure test protocol is attached to each plate heat exchanger as a service. For pressure equipment category 1 and 2, a declaration of conformity may be included.
For traceability, labeling and batch production, a suitable process has been implemented. It also ensures that the material used meets the specified requirements.
