Closed Water Systems Training

Closed Water Systems Training Course

World-class closed systems training delivered by leading experts.

WTS 0060 “Closed Water Systems – Heating & Cooling Water Circuits” is an intensive classroom based closed systems training course developed by the process water specialists at WTS.

The course is designed for facilities managers, water treatment service engineers, maintenance and engineering contractors, plant operators, and those with responsibility for the installation, pre-commissioning, maintenance and on-going management of commercial and industrial closed systems used in heating, chilled and cooling water installations.

What is closed water systems training?

Closed water systems training is a specialised professional development programme designed to equip water treatment engineers, facilities managers, maintenance staff, and contractors with the knowledge and skills needed to manage and maintain water systems that operate in a closed-loop configuration. In these systems, water is recirculated rather than being constantly replaced by fresh water. It helps prevent premature system failure and costly repairs by ensuring that water treatment and management practices are both effective and compliant with industry standards.

Overview of our closed systems course

WTS 0060 provides a review of typical closed water systems including low pressure hot water (LPHW) and low temperature hot water (LTHW) systems, medium pressure hot water (MPHW) and medium temperature hot water (MTHW) systems, chilled water systems, closed loops, condenser water (closed) systems, and Versatemp loop – circuit systems. Candidates taking this course will gain an understanding of the issues that affect the performance of closed water systems including metallic corrosion, fouling, bio-fouling and scale, and how best to deal with them.

Additionally, the course also covers a number of practical workshops, including how to conduct basic fault-finding investigations and the development of cost effective closed system water treatment solutions.
