Advanced energy solutions need advanced protection.
Enclosures built the way you need them.
When you need them.
Balancing calls for sustainable energy sources against increasing global power demand has led to an
unprecedented expansion of renewable energy technology development and rapid deployment. Protecting
vital controls, instruments and distribution equipment in an array of emerging technologies requires an
agile, capable and responsive global supplier. In energy applications, no one knows enclosures like Hoffman.
Modifications: the time- and cost-effective
alternative to custom.
When standard enclosures do not meet the needs of your
application, Hoffman is the only major enclosure manufacturer
that offers a full selection of modification options including:
Trusted solutions for the biofuel industry
Meeting the unique challenges of hydropower
With decades as a trusted partner in the petrochemical
industry, Hoffman has developed hundreds of products
and platforms specific to the needs of refinery and power
generation facilities. Today, Hoffman is one of the most
experienced and knowledgeable solution providers to the
biomass industry as well.
Protecting electronics and electrical equipment in hydroelectric
applications inherently presents corrosion challenges. Hoffman
offers more corrosion-resistant protection solutions in more

Advanced energy solutions need advanced protection.
Enclosures built the way you need them.
When you need them.
Balancing calls for sustainable energy sources against increasing global power demand has led to an
unprecedented expansion of renewable energy technology development and rapid deployment. Protecting
vital controls, instruments and distribution equipment in an array of emerging technologies requires an
agile, capable and responsive global supplier. In energy applications, no one knows enclosures like Hoffman.
Modifications: the time- and cost-effective
alternative to custom.
When standard enclosures do not meet the needs of your
application, Hoffman is the only major enclosure manufacturer
that offers a full selection of modification options including:
Trusted solutions for the biofuel industry
Meeting the unique challenges of hydropower
With decades as a trusted partner in the petrochemical
industry, Hoffman has developed hundreds of products
and platforms specific to the needs of refinery and power
generation facilities. Today, Hoffman is one of the most
experienced and knowledgeable solution providers to the
biomass industry as well.
Protecting electronics and electrical equipment in hydroelectric
applications inherently presents corrosion challenges. Hoffman
offers more corrosion-resistant protection solutions in more
materials, along with a host of conventional plant enclosures,
including operator workstations, for hydroelectric plants as
well as emerging marine and hydrokinetic technologies.
