Skid mounted - By Mounting Type

Skid mounted high voltage generator are designed to be mobile and quickly deployed to any operating areas, ideal for heavy Industry and construction sites. Made from steel, the units rest on skid frames for rapid transportation and lifting by forklift or crane.

Such flexibility is paramount in sectors like oil & gas, mining, and large industrial manufacturing where operations are constantly moving from site to site, or require temporary but substantial energy sources. Skid-mounted systems are often pre-piped and include the fuel tank, the control panel and the cooling system to further minimize installation cost and complexity.

They are also popular in disaster recovery areas, military outposts, and renting power services. They are not as physically stable and sound-deadening as stationary systems but the flexibility and affordability is very appealing in fast-paced, dynamic surroundings. Regulations such as portable emissions compliance and noise control particularly in urban or protected areas are having an effect on design improvements in new models, accelerating the transition to cleaner and quieter operation in the category.

Liquid-cooled - By Cooling Method

Liquid-cooled high-voltage generators are designed for maximum performance under severe continuous duty or high load factors that are routine in heavy industrial environments as well as high-load applications. These generators pump coolant fluids, such as water-glycol mixture or specially designed dielectric fluids, through heat exchangers to remove heat efficiently. This cooling retention ensures longer run times, low risk of overheating, and sustained optimal performance, particularly in confined or high heat conditions.

Sectors such as steel production, chemical processing and marine propulsion require liquid-cooled units because of their consistent performance and reduced risk of overheating. Although this includes the additional cost of installing and maintaining pumps and radiators, as well as the need to replace coolant, the savings in production risk are worth it for processes that cannot tolerate downtime.

Environment protection laws, including EPA Tier IV and EU Stage V are stimulating the development of advanced, non-toxic and bio-degradable cooling systems. The demand for hybrid cooling systems using both air and chilled water solutions for more efficient thermal management and regulation in varied climate conditions is also expanding in this sector.

Renewable Energy Companies - By End-User

Renewable energy companies are employing high voltage generators to reliably handle the power in remote areas or off-grid, such as solar farms and wind parks.
