Rental · testing
Our load banks provide comprehensive, flexible and cost-effective solutions for testing critical power systems. With a wide range of capacities and types, along with expert support and documentation, they ensure power systems are reliable, safe and ready to handle the demands placed on them.
Supply · connection · testing
Supply, connection and testing of transformers and MV & LV power cables, sized to your site load profile and commissioning programme. Every connection is verified before energisation and recorded in the test pack.
Commissioning · validation
Staged load runs up to 100% of rated capacity, with AVR and governor response, protection schemes, synchronising and load sharing all verified under real load. Witnessed testing with a documented report on completion.
Annual packages
Annual maintenance packages designed to keep your equipment operating at peak performance — minimising downtime and maximising efficiency across your estate, with scheduled service visits and priority emergency response.
Know your real back-up time.
Controlled discharge tests with our DC load banks verify the actual capacity and autonomy of UPS and battery systems — so weak strings are found before an outage, not during one.
Prove power and cooling before go-live.
Load banks simulate the IT load to commission generators, UPS, distribution and thermal systems — from single systems to full integration load tests.
