Steel production consumes huge amounts of heat. By increasing thermal efficiency, Alfa Laval heat exchangers reduce energy consumption, cost, and environmental impact. Their smaller size saves space, reduces installation outlay and makes it viable to build equipment using corrosion-resistant alloys, dealing with aggressive environments with ease.Self-cleaning technologies in our separation equipment minimize maintenance, reduce fouling and create revenue through re-use and resale of waste products.
CLOSED LOOP COOLING SYSTEMS
Well-designed cooling systems are vital given the complex processes and operating conditions encountered in blast, basic oxygen and electric arc furnaces, direct reduction plants and continuous casting machinery.
In a closed loop cooling system, good quality water is cooled in a secondary cooling system, consisting of plate heat exchangers cooled by sea water, river water or a cooling tower near the plant, creating benefits such as:
WHAT APPLICATION ARE YOU LOOKING FOR?
Efficient fluid cleaning / managemnet of your service fluids will pay off. Environment, tool life, quality and productivity will all gain from efficient cleaning with high speed separation. Do not replace the service fluids – take care of the fluids you have instead.
reduced maintenance, as fouling is moved from process equipment to the plate heat exchangers, which are easily maintained with simple chemical or mechanical cleaning systems
lower pumping costs, as pumps must overcome only the static height of the process equipment rather than the full cooling tower
reduced environmental impact, as cooling water is returned, unpolluted, to the sea or river.
Alfa Laval plate heat exchangers provide you with an efficient and compact alternative to the traditional shell-and-tubes used in cooling transformer oil, morg oil, lubricating oil and gear oil.
Our specially developed double-wall plate heat exchanger eliminates the risk of lubricating liquids and cooling media mixing during the process, avoiding costly consequences.
Alfa Laval plate and spiral heat exchangers achieve high turbulence, reducing the risk of fouling during operation and making chemical cleaning highly effective. Most of the heat transfer surfaces are easily maintained, as they can be reached simply by opening the unit.
Abrasive dust and sludge from centrifugal separation can be highly corrosive. Alfa Laval decanter centrifuges incorporate advanced protection against harsh environments and use surfacing materials capable of combating wear and corrosion
