The most advanced vapour recovery sealing fluid on the market.

Our vapour recovery sealing fluid, FLOSEAL, can improve Vapour Recovery Unit (VRU) efficiency by reducing seal liquid consumption as well as the blockages and component damage associated with common commercial glycol use.

The most advanced fluid on the market, FLOSEAL contains additives that actively prevent gel formation, corrosion, foaming and biocide activity, reducing VRU maintenance costs as a result.

Our team drew on 20 years of experience in servicing VRUs to develop FLOSEAL.

  • Formulated using a unique blend of additives specially developed for use in Carbon Bed VRU vacuum pump seal systems.
  • Key components include steel corrosion inhibitors, anti-oxidants, anti-foam, pH stabilising and biocide additives.
  • Available coloured or clear.
  • Supplied in 200 litre drums or 1000 litre IBCs.

Common commercial glycols can cause long-term issues such as clogging, blocking and corrosion when used within VRUs. This is because the chemical makeup of most commercial glycols is formulated for its primary use as an anti-freeze in motor vehicles. Most of these formulations contain meta-silicates intended to prevent the corrosion of aluminium components. When used in VRU operation, these silicates drop out of the solution and contaminate the seal system causing blockages and component damage. 

In addition, commercial glycols by nature tend to break down in the VRU circulation system and form gels. These gels coagulate in parts of the seal system, blocking filters and coating the internal surfaces of the pipes and vessels – ultimately increasing VRU downtime and high maintenance costs.

The additives within FLOSEAL actively prevent gel formulation and in cases where heavy glycol consumption is experienced, changing to FLOSEAL has resulted in a reduction in seal liquid consumption.

Additional benefits of FLOSEAL include;

  • Reduces gelling, corrosion, foaming and biocide activity.
  • Is coloured for better visibility through sight glasses but can be provided clear upon request.
  • Drums can be recycled reducing cost for disposal for users.
  • Supplied in 200-litre drums or 1000 litre IBCs.
