Precleaning & passivation chemicals are used as part of the initial treatment and commissioning process for chilled water systems, chillers, heat exchangers and associated piping.
Newly installed or modified chilled water systems may contain oil, grease, construction debris, mill scale, rust, dirt and other surface contaminants. Precleaning helps remove these unwanted materials from the system before the regular chilled water treatment program is started.
Following the cleaning stage, passivation treatment helps support the development of a protective surface condition on compatible metal components, helping prepare the system for ongoing chilled water treatment.
InChem Corporation provides requirement-based precleaning and passivation chemical solutions according to system materials, water quality, system volume, operating conditions and project requirements.
Precleaning & passivation chemicals are used during the initial preparation of chilled water systems before the commencement of regular chemical treatment.
During installation and commissioning, chilled water piping, chillers, heat exchangers and associated components can contain manufacturing residues, oils, grease, dirt, construction materials, mill scale and other contaminants. These materials can interfere with water treatment and may contribute to water-quality and corrosion-related concerns.
The precleaning stage is intended to help remove these contaminants and prepare the internal surfaces of the system. Following suitable cleaning, passivation treatment can be applied to support the development of a protective surface condition on compatible metal surfaces.
The treatment program should be selected according to system metallurgy, water chemistry, system volume, equipment condition and individual project requirements.
Precleaning and passivation should be carried out according to an appropriate treatment procedure, with suitable circulation, monitoring, flushing and water-quality checks before the system is placed under the regular chilled water treatment program.
Helps remove oils, grease, dirt, residues and other contaminants from chilled water circuits.
Supports preparation of internal metal surfaces before regular water treatment begins.
Helps establish a suitable protective surface condition on compatible metal components.
Supports removal of unwanted contaminants from internal chilled water surfaces.
Provides a structured treatment approach before starting routine chilled water treatment.
Passivation treatment helps support protective surface conditions on suitable metallic components.
A properly cleaned system provides a better starting condition for an ongoing chilled water treatment program.

Get In TouchThey are treatment chemicals used to help clean chilled water systems and prepare compatible metal surfaces for ongoing water treatment.
Passivation is a treatment process intended to support the formation of a protective surface condition on suitable metal surfaces, helping manage corrosion-related conditions.
They can be used in chilled water piping, chillers, heat exchangers and associated HVAC water circuits.
InChem Corporation provides specialised water treatment solutions for chilled water systems, chillers and HVAC applications. Our precleaning and passivation chemicals are designed to support the initial cleaning and preparation of chilled water systems before regular water treatment begins.
The treatment approach is selected according to system materials, water quality, system volume, contamination conditions and individual project requirements. Precleaning and passivation can form an important initial stage of a broader chilled water treatment program, followed by appropriate chemical dosing, filtration and routine water-quality monitoring.
InChem Corporation focuses on practical, requirement-based water treatment solutions designed to support cleaner system surfaces, suitable metal surface conditions and reliable chilled water system operation.
