Oil care and testing

Flushing, Tank Cleaning and Oil Analysis

Oil Flushing

Hydraulic and lube oil systems flushed after installation or repair, with our 1,200 litre-a-minute flushing rig and a separate 300 litre-a-minute pump.

Tank Cleaning

Sludge, water and scale taken out of oil, fuel and chemical storage tanks, with or without entry as the tank allows.

Tank Pickling, Passivation & Degreasing

Stainless and carbon steel tanks of 50 litres to 300 KL (300,000 litres) degreased, pickled where heat tint, scale or rust needs it, and passivated.

Filter Cleaning

Mesh filter elements, strainer baskets and fuel oil filter housings washed, back-flushed and checked before they return to service.

Oil Varnish Removal and Testing

For sticking valves and oil that counts clean yet leaves deposits: electrostatic cleaning of suitable oils, with a varnish test where quoted.

Oil Analysis

Oil tested at our NABL-accredited partner laboratory, with particle count and breakdown voltage (BDV) checks at your site.

Predictive maintenance

Thermography and Vibration Analysis

Electrical Thermography

An infrared survey of panels, switchgear and transformers under load, to find hot spots before they fail.

Mechanical Thermography

Infrared checks of bearings, motors, steam traps and refractory, to plan repairs before a breakdown.

Vibration Analysis With IoT Monitoring

Vibration surveys and IoT sensors that watch rotating machines, so faults are found before they stop production.

Individual Vibration Analysis

In-depth vibration diagnosis for one critical machine with a chronic problem.

Electrical and Safety Audit

An audit of your electrical installation, carried out together with our partner.

Plant Audits

Electrical, thermal, fuel oil, insulation, oil and compressed air audits of your plant, booked one at a time or together.

Heat transfer and cooling

Heat Exchangers and Thermal Systems

Plate Heat Exchangers

Gasketed plate heat exchangers supplied, installed and commissioned for industrial heating, cooling and heat recovery.

PHE Spares & Gaskets

Gaskets and spare plates for the major PHE brands, with re-gasketing at your site.

Heat Exchanger Servicing & Retrofits

Chemical and mechanical cleaning of shell-and-tube, plate, air-cooled and spiral exchangers, back towards design duty.

Thermal System Solutions

Design, supply and maintenance of thermic fluid heaters, steam systems and heat recovery units.

Electrochemical & Cooling Solutions

Cooling water analysis, chemical dosing and cooling tower maintenance against scale, corrosion and fouling.

Pipeline system solutions

Pipeline Cleaning and Commissioning

Pipeline Flushing

Scope review for new or serviced hydraulic and lube oil systems.

Pipeline Pickling & Passivation

Acid pickling to remove weld oxide and scale, then passivation to restore corrosion resistance, on installed piping.

Chemical Cleaning of Pipelines

Scale, deposits and fouling dissolved out of process pipelines by circulating the right chemical.

Boiler Chemical Cleaning

Scale, rust and mill scale taken out of boiler tubes, drums and headers, and out of the pre-boiler lines that feed them.

Degreasing of Pipelines

Oil, grease and cutting fluid cleaned out of new and installed pipework before pickling, flushing or start-up; cleaning for oxygen service is a separate service.

Gas Line Flushing & Oxygen Tank Cleaning

Gas lines flushed to remove moisture, sediment and particles, and oxygen tanks cleaned free of oil and grease.

Nitrogen Purging & Pre-commissioning

The atmosphere in chosen lines and systems replaced with inert nitrogen, as one stage before start-up; moving leftover liquid is planned separately.

Commissioning

Commissioning of pipelines, machines, heat exchangers and chillers at your plant, from the last checks and cleaning to start-up.

Coatings and repair

Protective and Thermal Spray Coatings

Protective Coatings

Coating work on tanks, pipelines and vessels, scoped from the metal, its service and its condition, with the quotation stating who does it.

Thermal Spray Coatings

Sprayed repair coatings such as HVOF for worn shafts, journals and valve surfaces, with a plain answer on whether one suits your part.

Start From What You See

Not sure which service you need? Find your symptom, and the page behind it says what we do and what we need from you.

Industrial oil filtration: oil that is dark, wet, gritty or sludgy, or filters that block too soon
Oil flushing: a new, repaired or contaminated hydraulic or lube system that must be cleaned before it runs
Oil analysis: oil you are unsure about, or a trend you want to watch
Tank cleaning: a tank with sludge, water or scale in it
Pipeline flushing: new or altered pipework to clean before start-up
Electrical thermography: hot panels, switchgear or connections
Individual vibration analysis: one machine that keeps failing or shaking
Heat exchanger servicing: an exchanger that runs hot, leaks or has lost performance

Questions About Our Services

Which service do I need if I am not sure what is wrong?

Send the oil type, the volume and what you see, or your latest oil report. If nobody knows yet, start with oil analysis: its report tells us whether the oil needs filtering, the system flushing or the oil changing, while a fault in the machine itself is for your maintenance team to find. We then suggest the service that fits.

Do you work outside Tamil Nadu?

On site, across India, from Chennai. Transformer oil filtration is offered in Tamil Nadu only. How a job outside Tamil Nadu runs is on the Working across India page.

Which of these services does your ISO 9001:2015 certificate cover?

It covers the field services named on the certificate, and the About page lists them. Heat exchanger and cooling work is not among them, and neither are products or rentals.

Do you also supply parts and rent machines?

Yes. We supply hydraulic products as a supplier, not the maker. Rented equipment includes a vacuum dehydration machine, a coolant sump cleaner and a particle counter. See the Products and Rentals pages.

Schedule a Plant Walkthrough

Our team can come to your site to see the system and the oil, take a sample if needed and tell you what it needs.
