Water hydraulic systems have numerous advantages over their oil counterparts.
NON POLLUTING
All hydraulic systems leak at some time within their life span. Potential contamination to first and most importantly the person using or maintaining the system must be assessed.
Secondly the risk to the product or service in which the system is adopted and thirdly the environment in which it is used must be taken into account
Make a risk assessment for your product containing oil against the same system driven by water and view the impact to people, product and environment.
The improvement will ensure your product is viewed as a market leader with better industrial health compliance also reducing environmental liability and risk.
Your customer may benefit from lower insurance cost by demonstrating proof of good management before pollution incidents occur.
FIRE RISK
Systems operating in high fire risk areas can not adopt standard oil systems.
The non flammable hydraulic alternatives are usually highly toxic. Water offers neither fire risk or toxic threat. Insurance premiums may be reduced by adopting such a system
EFFICIENT
Individual components offer the same and in some cases improved performance to that of a comparable oil unit.
The transmission of fluid however offers greater efficiency improvements thereby reducing the size of components and absorbed power for a given output. The virtual incompressibility of water offers excellent controllability with a rapid response.
COST EFFECTIVE
The cost of the fluid is not the only major saving to be gained by adopting a water hydraulic system.
Assessment of meeting new stringent regulations regarding storage, cleaning of spillages, special protective clothing for users, material handling of bulk fluids, meeting manufacturers specific fluid demands and adhering to disposal legislation must be undertaken. Logistics and management time for all of the points is removed when the hydraulic fluid is taken from the tap and disposed of down any domestic drain.
GREEN
Companies in the past have given lip service to environmental issues.
ISO 14000 international standard was to prevent violations, fines and negative publicity for non complying companies.
On the positive side it also assists companies who produce environmentally friendly products and assists them to profit in the market for "green" products
THERE IS NO GREENER DRIVE THAN WATER
DESALINATION
The power centre combines the operation of an axial piston high pressure desalination pump with an axial piston motor utilizing the pressure in the waste brine to assist the electric motor in driving the pump and so reducing the power requirement to typically less than 3kW/m³ of permeate. The power centre has been purpose designed and built for the RO market.
Due to the integrated nature of the power centre design the footprint is much reduced, nor is there at the need for all the additional fluid couplings which makes for a very compact system ideal for ships and offshore platforms. Reduced complexity of the system components and hence cost.
