Flushing and Chemical Cleaning Services

There are a number of pitfalls that can arise when carrying out chemical cleaning operations on systems pipework, from the selection of the appropriate chemicals, to the hazard levels and the amount of waste disposal.

At EnerMech we have developed a unique in-house process for the chemical cleaning of pipework systems. The process utilizes a suite of chemicals which are less hazardous and more environmentally friendly than traditional products. EnerMech’s specialist teams will assemble a cleaning "spread" including pumping units, temporary hoses and pipework, heating coils, exchangers, circulating tanks and analytical/control equipment.

One of the most difficult chemical cleaning applications is that of Printed Circuit Heat Exchangers (PCHE). Due to the design of these units, the channels within the unit are extremely small in diameter (2mm), making normal conventional cleaning almost impossible.

We have developed an extremely effective and efficient method of cleaning PCHE, which can be carried out either in our yard or sites out with our facilities. The method involves a combination of a chemical cleaning circulation, in conjunction with a series of gas puffing operations, which will ensure the optimum conditions inside the PCHE, and produce an effective and efficient cleaning programme.
