Continued use of heat transferfluids results in a breakdown ofthe liquid. This can be simplythe result of general wear andtear though this will accelerateat extreme high or lowtemperatures.

System malfunction or poordesign can result in additionalstress on the fluids.

The build up of ‘high boilers’can generally be easily eliminated through good systemdesign or modification.

With the build up of lowboilers, the flash and firepoints will decline, oftenwith a lowered auto-ignitiontemperature.

System modifications canslow this degradationthough an increase in fluidflammability is inevitable.

In order to remove theVOC’s, HTS have designed

a range of mobile and fixed reconditioning units based on‘nitrogen stripping’ and ‘distillation’ principles.

TECHNICAL ISSUE 1

Does the build up of VOC’s within your bulk heat transfer fluids resultin lowered flash points, fire pointand auto-ignition temperature?

Two mobile reconditioningplants en route to DowChemicals, Teneuzen

A range of configurations are ideallysuited to the following situations:

On line VOC removal:To remove VOC’s on line to maintain high flash points, fire point and auto-ignition point.

On line water removal:Following accidental water ingress or heat exchanger failure.

At commissioning:To dry and condition fluid followinginstallation or system modification:

Permanent Installation:For regular removal of VOC’s to maintainthe best possible fluid condition.

In Emergency:To remove water / VOC’s to enable eitherhigh temperature or sub-zero operation.

Example 1: MDF ManufacturerSystem Content: 20,000 litres Fluid: Mobiltherm 605Quantity VOC’s removed: 1,400 litres

What can be done?We have considerable experience ofremoving VOC’s and water from heattransfer systems.

With hundreds of successful operationsalready undertaken we are likely to beable to meet the requirements of yoursystem.

Our units – available for hire or purchase– are connected to the main system as aside stream, taking a proportion of theflow through our ’flash chamber’ wherethe vapour release is stripped through acondenser for safe disposal.

This is undertaken during normaloperation with no system downtime.
