Chemical processes
suitable for all kinds
of heat exchangers
Our chemical treatments are specially designed to clean the majority of industrial heat exchangers (shell and tube, plate, coaxial) made from materials such as stainless steel, carbon steel and other alloys (copper, titanium, etc.), on both of the relevant sides.
We have developed suitable chemical processes for removing build-ups, including limescale, salts, metal oxides and biofilms, as well as organic hydrocarbon deposits.
Our chemical cleaning services include:
The aim is to restore the thermal capacities of heat exchangers, while maintaining the integrity of equipment.
Depending on the circumstances, this improved efficiency results in an increase in the flow of cooling water, a reduction in the circuit’s pressure loss, an improved process fluid temperature and, in all cases, a rapid return on investment.
The availability of specially designed compact cleaning skids facilitates a rapid response, thereby reducing downtimes.
We have also developed a specific process for cleaning certain heat exchangers that are more critical than others (Optiflow® process) without stopping production.
This application, combined with online cleaning of fired heaters or air-cooled heat exchangers/air-cooled condensers (Neutramex® process), as well as online cleaning of heat exchangers in the preheat train, facilitates the “debottlenecking” of production units, including atmospheric distillation and vacuum distillation.
Chemical cleaning of a heat-exchanger
A thermal power plant in New Caledonia asked CTP environment Asia Pacific to carry out chemical descaling of a steam condenser.
CTP environment Asia Pacific developed an optimum chemical cleaning procedure, which incorporated effectiveness, in terms of the residue to be dissolved, as well as protecting the integrity of the materials exposed.
Sustainability is at the core of our DNA.
Today, we are especially proud to announce the achievement of the prestigious EcoVadis Gold Medal, recognizing our concrete actions in Corporate Social Responsibility (CSR).
We attended the 7th International Congress on Environmental and Health Risk Management for Contaminated Sites, which took place in Paris from 16 to 19 June 2026.
We exhibited at the AsiaWater expo and forum 2026, back at the Kuala Lumpur Convention Centre (KLCC) from 7-9 Apr 2026. This 14th edition was set to be a platform for the water industry in developing Asia, to experience the innovations in water management, from resource management to wastewater treatment.
