In light of energy use accounting for up to 85% of the life cycle cost of a pump system, Grundfos Pumps offers an Energy Check service which, it says, results in significant increases in process efficiency and savings.
The Energy Check is described as a comprehensive report that will outline facts about a customer’s current installation and operational costs. This will include an overview on the potential savings that could be reached through upgrading all or some of the system to a new energy-efficient solution.
Besides these specific points, the report will also contain additional recommendations and a step-by-step implementation plan.
A Grundfos report requires no downtime to complete, says the company, and details potential savings on: electricity use (kWh/yr); electricity charges; maintenance and repairs; cost of new pump investment; ROI; CO2 emission reductions (tonnes/year); and life cycle analysis of pump installation.
Two recent examples of the benefits have been a 700+ bed hospital in the North West and a large hotel in the South of England.
An energy check indicated that exchanging a number of end suction and in-line pumps for more efficient models could save the hospital 429,645 kWh per year with an ROI of 1.5 years.
For the hotel, results suggested replacing existing pumps with a variable-speed efficient option could generate savings of 787,572.80 kWh/year with a payback period of two years.
Typically, says Grundfos, pump upgrades produce a 30% reduction of CO2 emissions, and the companys says its MAGNA3 family of products ensures greater compliance with energy regulations.
