Our areas of Expertise


COOLING TOWER TREATMENT
We understand that the water treatment of cooling towers is an integral part of process operations in many industries, with the possibility of productivity and product quality being adversely affected by scale, corrosion, fouling and microbiological contamination.These water treatment problems can be very costly when they cause the loss of heat transfer in cooling tower,equipment failure, and health and safety concerns.
So we are here to help all out from this problem.


BOILER TREATMENT
Poor water quality can result in significant operational problems and possible shut down of boiler systems. To limit the potential for scaling, deposition and corrosion, most boiler water is treated physically or chemically to remove impurities and improve efficiency in the system. We a here with good product and workforce to help you before the problem occur; act before it become too late.

PRE TREATMENT
The term "pretreatment" means the treatment of wastewater by commercial and industrial facilities to remove harmful pollutants before being discharged to a sewer system under the control of a publicly owned treatment works. The treatment helps to, prevent interference with the operation of your wastewater treatment plant untreated and into the receiving body of water, improve opportunities for reuse or recycling of wastewater and sewage sludge and prevent the introduction of pollutants that could cause health or safety problems to the public or the environment.

WATER CONVERSION
Water conservation includes all the policies, strategies and activities to sustainably manage the natural resource of fresh water, to protect the hydrosphere, and to meet the current and future human demand. Water conservation helps to ensuring availability of water for future generations where the withdrawal of freshwater from an ecosystem does not exceed its natural replacement rate.


ENERGY CONSERVATION
Energy can be conserved by reducing wastage and losses, improvement in efficiency by technological upgradation and improved operation and maintenance. Energy conservation are efforts made to reduce the consumption of energy by using less of an energy service. This can be achieved either by using energy more efficiently or by reducing the amount of services. Energy conservation is a part of the concept of eco-sufficiency. Energy conservation reduces the need for energy services, and can result in increased environmental quality, national security, personal financial security and higher savings.
Waste water problem
Many industries produce a contaminated water waste as part of the processes involved in the industry. Industrial wastewater treatment describes the mechanisms and processes used to treat this wastewater. After treatment, the treated industrial wastewater (or effluent) may be reused or released to a sanitary sewer or to a surface water in the environment.

CLEANING SERVICES
Heat Exchanger Flushing
 
 
Regular maintenance is common, your car needs to be serviced, your computer needs to be updated, and your heat exchanger needs proper maintenance. Properly cleaning your plate and frame heat exchanger is very important. One main and important reason is efficiency. In order to keep the flow rates and pressure levels at the designed unit specifications and the heat transfer as optimal as possible the plates need to be clean. Over time, the various types of fluids that are run through the heat exchanger can start to develop process build up or scaling on the plates. This scaling reduces: flow rates, heat transfer and the efficiency of the heat exchanger.

Benefits of HVAC System Cleaning
Why should you have your HVAC system cleaned? The short answer is simple: because they get dirty over time and they have the potential to contain large amounts of dust and particulates.

Energy Savings
According to the U.S. Department of Energy, 25 to 40 percent of the energy used for heating or cooling is wasted. Contaminants in the heating and cooling system cause it to work harder and shorten the life of your system. Although filters are used, the heating and cooling system still gets dirty through normal use. When an HVAC system is clean, it doesn’t have to work as hard to maintain the temperature you desire. As a result, less energy is used, leading to improved cost-effectiveness.

Indoor Air Quality
Indoor air quality is one concern that building managers and building inhabitants have when they decide to investigate HVAC system. Through normal occupation in a building, we generate a great deal of contaminants and air pollutants, such as dander, dust, and chemicals. These contaminants are pulled into the HVAC system and re-circulated 5 to 7 times per day, on average. Over time, this re-circulation causes a build-up of contaminants in the ductwork.While a contaminated HVAC system doesn't necessarily mean unhealthy air, the situation may be contributing to larger health issues or harboring contaminants that could cause serious problems for people with respiratory health conditions, autoimmune disorders or some environmental allergies.

Benefits of HVAC Inspection
HVAC inspectors conduct comprehensive examinations of components and systems to determine whether they are contaminated with a significant accumulation of particulate or microbial growth, or if HVAC performance is compromised due to contamination build-up.The role of an HVAC inspector is to assess the cleanliness and structural integrity of an HVAC system. Inspectors search for obstructions, excess moisture and microbial contamination in the HVAC system.

Cooling Towers

Cooling towers move air through the water system with a fan, allowing water vapor to sit within the system. The water vapor can stay within the ideal temperature range (20°-50°C; 68°-122°F) for LDB to grow, according to the Occupational Safety and Health Administration. Cooling tower water becomes dirty with slime, algae, sludge and mud, all which builds up on the basin floor. Legionella bacteria thrive underneath the layers of slime and scale. Dirty water can affect chiller operating efficiency and increase energy costs. Clean the tower whenever scale, slime or sediment is present. And disinfecting after cleaning stops future bacterial growth.

Tower vacuums remove slime, mud, algae, bacteria and other contaminants from the sides and floor of the cooling tower basin. An accessory kit extends cleaning performance with additional hoses and various brushes. Our “How To Clean Cooling Towers” checklist details the step-by-step tower cleaning process. Spraying a foaming detergent on the tower dissolves tough deposits. Adding a biocide product to the tower water after cleaning the basin prevents bacterial growth.
Chiller Condenser unit flushing
 
 
To prevent buildup of scale and sediment you must maintain your chiller tubes according to the manufacturer’s directions. Periodic maintenance helps control the growth of Legionnaires’ disease bacteria (LDB) and other organisms.

In many organizations chillers use the most energy, so regular cleaning and maintenance ensure that they operate reliably and efficiently. As mentioned in the previous post, chiller performance is related to its heat transfer efficiency. There are miles of tubing in a chiller’s heat exchangers so keeping the tubes clean means the chiller will perform more efficiently.

Tubes can become caked with mud, slime, sludge, algae and scale. The rate at which the tubes become clogged can vary with the type of system as well as with water quality issues. Closed systems may not need to be cleaned as often; chiller manufacturers typically recommend periodic inspections for open systems.

When tubes become packed solid with deposits, a water flush with a tube cleaner cleans clogged tubes quickly. Our “How To Clean Chiller Tubes” checklist details the step-by-step tube cleaning process. Using the right tools softens heavy deposits and removes all build up including soft deposits like mud and algae.RNC use external circulation pump to clean both straight and spiral enhanced chiller tubes. Our chemical descalers work to soften thick scale and speed up the cleaning process. Periodic descaling prevents future build up.

HOW THICK IS THE SLUDGE IN YOUR
WATER TANK?
Our specialist equipment efficiently removes sludge from your tank, and clean your tank of bacteria carrying sediment, leaf litter, insects, birds, vermin and all other types of critters.

When was the last time you had your Water Tank Cleaned?

Most people claim they have never had their rainwater tank cleaned, and claim the water is just fine; just a hint of colour or a slight taste.

Why should you clean your Water Tank?
Over time leaves and debris enter the tank and begin to decompose on the bottom of the tank, turning the water a dark brown colour. Tank cleaning can reduce potential damage to your Water Pump, blockages of pipes, increase the life of your water filters, and where there are no filters, potential damage to your tapware, and is the first stage in ensuring the purity of your drinking water supply.

How often do you clean a Water Tank?
The Ministry of Health recommends annual tank cleaning – however with appropriate filtration and bacteria control (UV) this can typically be 1-3 years.

Oil Cooler
 
 
RNC has developed methods
and technologies that efficiently clean a wide
variety of systems.

Life extension of oil cooler to benefit for the owners is a one of the business for RNC. Cleaning and refitting lube oil coolers is a part. Keeping the recommended temperature in the lube oil system is significant for the lube oils lifetime and capability as lube for the fast rotating and moving parts in e.g. gearboxes and hydraulic pivoting systems. However the harsh environment for off shore turbines has impact on the lube and hydraulic oil cooling systems over time. Meaning replacement of oil and cooler liquids maybe needed. And even retrofitting the cooler system, to maintain a proper working temperature to benefit for the oil and lubricating oil system. Contamination and raised temperatures. Lubricating oil systems may be affected and contaminated due to water, metal particles, stain and rust etc. occurring in the system over time. Accumulated contamination may lead to reduced flow and by this increasing working temperatures reducing the lubrication.
