Overview

Water Propylene Glycol MIXTURE, 50/50 used as a BARRIER FLUID

Product description

PROPYLENE GLYCOL Barrier Fluid supplier and exporter. Water Propylene Glycol MIXTURE, 50/50 used as a BARRIER FLUID.

Barrier Fluid is a formulated, ready-to-use mixture of USP/industrial grade propylene glycol and de-ionized water with a tailored corrosion-inhibitor package and defoamer. It provides freeze protection, lubrication for mechanical seals and bearings, and corrosion control in closed systems where a low-toxicity fluid is preferred. Anti-Freeze / Coolant, 50/50 Propylene Glycol premix, multi-metal inhibitor, ready-to-use solution

It provides reliable protection against freezing, overheating, and corrosion in automotive and industrial cooling systems. Compared to ethylene glycol–based coolants, it offers a safer toxicity profile, making it suitable for environmentally sensitive applications. The product is designed for long-lasting performance and compatibility with a wide range of metals, seals, and elastomers.

Applications

Water Propylene Glycol MIXTURE, 50/50 used as a BARRIER FLUID

Areas of application of Barrier Fluid Proprylene Glycol

Mechanical Seal Systems
  • As a pressurized or unpressurized barrier/buffer fluid for double mechanical seals in pumps, agitators, and mixers.
  • Provides lubrication, cooling, and protection of seal faces, extending seal life and reducing downtime.
 
Closed-Loop Cooling & Heating Systems
  • Used as a heat-transfer medium where freeze protection and corrosion control are required.
  • Suitable for cooling water jackets, compressor systems, and auxiliary equipment.
 
Chemical & Petrochemical Plants
  • As a seal barrier fluid in rotating equipment handling aggressive or hazardous process fluids.
  • Protects against cross-contamination between process side and atmosphere.
 
Power Generation & Utilities
  • For barrier systems in boiler feed pumps, condensate pumps, and circulation pumps.
 
Marine & Offshore Applications
  • Suitable as a barrier/buffer fluid for mechanical seals in marine pumps, compressors, and deck machinery operating in cold or variable climates.

Dosage

Usage of Barrier Fluid

  • Use: Designed as a barrier fluid for mechanical seal systems and as a heat transfer/antifreeze fluid in closed-loop systems. Not for ingestion or food contact.
  • System preparation: Flush system thoroughly to remove oils, scale and residues before filling. For best corrosion protection, fill with supplied product (do not mix with unknown fluids).
  • Top-up: Use only the same product to top up. If mixing with other glycols, check compatibility and inhibitor chemistry.
  • Monitoring: Periodically test sample for pH, freeze point, inhibitor concentration and conductivity. Replace fluid if contamination or degraded inhibitor levels are detected.

Notes

Key Features of Barrier Fluid Propylene Glycol

  • Low toxicity alternative to ethylene glycol (reduced ingestion hazard).
  • Good freeze protection for typical industrial applications.
  • Corrosion inhibition for ferrous and non-ferrous metals (with inhibitor package).
  • Compatible with common elastomers and seal materials when tested (see compatibility).
  • Ready-to-use (no onsite dilution required).
