Air Compressors – Experience & Range
Unmatched Experience in Air Compressor Specification, Installation & Support
Harold Engineering has over 40 years experience in the specification, installation and maintenance of air compressors and complete compressed air solutions. From small piston air compressors, to large oil free and centrifugal compressed air systems, our team understand the specific requirements of each application.
With thousands of installations in place across all sectors of Irish industry we work on a foundation of knowledge that is second to none. This allows us to specify the optimum compressed air system comprising of the compressor itself, the air distribution network and the necessary air treatment equipment for the specific application.
Optimising Life Cycle Cost
In times gone by the selection of capital equipment was based largely on the initial capital outlay for the equipment. Harold Engineering prefers to also take into account the total costs of maintenance and energy costs for the expected life of the equipment, identifying the real costs of owning and running the compressor. In this way the truly most cost effective solution can be arrived at with savings accruing to the customer.
The compressor itself must deliver the optimum balance between Free Air Delivery and energy efficiency. Air compressors, by their nature, consume substantial electric power and substantial savings can be achieved if the equipment is correctly specified to suit the application. Variable speed drive air compressors will deliver considerable energy savings where the compressed air requirement is inconsistent or where the compressor is used to just top up the supply of other compressors.
Like many industries, the compressed air sector has benefitted enormously from the introduction of intelligent control systems. These enable the running of the compressed air system to be truly optimized, ensuring world class energy performance. Harold Engineering has installed numerous Ingersoll Rand Intelliflow systems which have delivered a level of energy savings to the customer that gives less than six month payback on capital cost. Likewise the introduction of Ingersoll Rand XE controllers and Renner Rennertronic controllers delivers energy savings to a wide range of installations.
Air Distribution Systems
At design stage of the project the specification of the air distribution network will be critical to how the compressed air system performs and the flexibility it offers. Some air distribution systems will require multiple drop points whilst others will just call for a simple supply direct to the application. Depending on the requirements of the customer, conventional gun-barrel, plastic, or modular pipework will be employed, and Harold Engineering will recommend the optimum solution.
Oil Free Compressed Air & Air Treatment
The end application will determine the quality of compressed air that is required. In applications in some industries such as the food, medical and pharmaceutical sectors there may be a need for oil free compressed air and Harold Engineering has extensive experience in this regard.
In designing the system it is also necessary to determine what air treatment is required in terms of filtration and dew point. Harold Engineering’s experience in demanding industries such as the Food, and Med/Pharma sectors equips us with the knowledge to specify and install the correct combination of filters and air dryers to supply compressed air for the most exacting processes.
