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.).
