Closed-Loop Systems
Cooling water, chilled water, glycol and hot water circuits, cleaned and passivated through the system’s own circulation.

Pipeline and closed-loop cleaning
GTS cleans pipelines and any closed-loop system, from cooling and chilled water circuits to boilers, exchangers and lube oil systems, using cleaning chemistry it supplies and crews it employs, so one Saudi team answers for the chemical, the method and the result.
Scope
Cooling water, chilled water, glycol and hot water circuits, cleaned and passivated through the system’s own circulation.
Pigging, chemical cleaning, crude removal and decontamination of transmission, flow and process lines.
Heat exchangers, vessels, boilers and process piping, cleaned in place or off-line.

The GTS difference
Most cleaning jobs pass between a chemical supplier and a separate service contractor. GTS brings both together in the Kingdom, so the treatment, the people applying it and the outcome sit with one team.
Cleaning chemicals selected for the deposit, the metallurgy and the system volume, drawn from GTS stock and checked in the GTS laboratory.
GTS crews and equipment mobilise from the Eastern Province, with no wait for specialists to fly in.
A single method statement, a single permit interface and a single completion report covering the chemical and the work.
