Air Cooled Condensers

The same philosophy of remote jetting technologies is applied to cleaning of fins fans and vertically mounted Air Cooled Condensers greatly   improving efficiency and reducing production costs. RISAL also offer foam cleaning and dry powder cleaning to provide the full range of options for improving fin fan efficiency. 

Surface Preparation

RISAL can provide cleaning and surface preparation on high level vertical surfaces such as tank walls without scaffolding. Operating at pressures up to 40,000psi the spider jet is controlled from the ground level to provide full surface coverage. The vacuum recovery system contains and removes all water and debris from the cleaning service without spillage. The system can be used to remove coatings for entire tank surfaces safely, efficiently and quickly. 

Cold Cutting

RISAL provide cold cutting services using high pressure water to cut through metal in situations where hot work is not permitted. Used in areas where there is a risk of hydrocarbon this technique is used to cut through pipework removing spools for replacement, creating access into tanks, removal of tank floor plates and can be adapted to almost any application . Cold cutting can be used to cut through any steel and without the thermal and mechanical stresses which can be experienced in other cutting methods. 

Hydro Milling

RISAL’s hydro milling services offer the best in pipe internal cleaning. Operating at up to 150,000psi and 70gpm the specially designed system can precisely clean large diameter pipework up to 72” negotiating multiple elbows and even vertical configurations.  The rotating hose system and specially designed cleaning heads ensure that the maximum cleaning force is delivered directly to the surface with precise control. Our technicians will design the cleaning heads for your specific application, be it detailed removal of mill scale to decoking process piping.

In line with our commitment to introducing the latest technologies, RISAL offer Ultrasonic Cleaning Services. Used in conjunction with specially designed chemistry the ultrasonic cleaning bath offers improved cleaning quality and time. Of particular benefit to complex components such as pumps, valves, packings, demisters, process filters and heat exchangers the ultrasonic cleaning technology is able to penetrate into every area of the component removing debris without damage to the valuable equipment. Components can be delivered to RISALs facility for cleaning or the bath can be mobilized to the client site for shutdowns campaigns or located permanently in the maintenance shops. 

Tank Cleaning and Maintenance

Tank Cleaning

In line with our commitment to investment in technology, safety and the environment RISAL have agreed a partnership with Sky Gulf to introduce Automated Tank Cleaning Services. Using the latest proven technology RISAL can now clean the largest crude and fuel oil tanks without the need for confined space entry. Modeling each individual tank a procedure is developed to ensure the most efficient process is employed to clean the tank and return to service with the minimum down time. Oil is drawn from the vessel and circulated through our containerised pumping and heating system and reinjected to the vessel through a special cleaning nozzle arrangement breaking down the sludge. The product is then separated to recover over 90% hydrocarbon from the sludge leaving only non-contaminated solids and water. The recovered hydrocarbon is returned to the  as useable product ensuring the cleaning exercise is not only efficient but also cost effective. Reducing downtime, improving safety and environmental practice in a cost effective manner, RISAL offer the complete solution in tank cleaning services.
