MODERNIZATIONS Power Unit NGV-EK Range

02C13ENG006

The NGV-EK Power Units have been designed to upgrade existing hydraulic elevators with mechanical valves. You can install the latest technology of Electronic Valves NGV-EK in a fast and easy way, without making any changes to the control panel.

ADVANTAGES FOR LIFT COMPANY

• Fast and easy modernization of existing installation, with no costs for changing control panels.

• Offering a quick and economical solution to the customer.• Reduced cost of maintenance and service.• GMV Warranty.• Adjustable inspection speed, increasing security during maintenance

works.• Produces a customized study to reduce consumption and contracted

power.

USER ADVANTAGES

• Improved comfort during the start, running and stop phases.

• Improved stopping by using NGV-EK Valves.• Increasing SPH (starting per hour).• Integrates dual security system according to EN 81.2-A3.• Reduced energy consumption of lifts up to 40% depending on installation,

thanks to DRY motors, which leads to a reduction of contracted power and electricity cost.

TECHNOLOGY DRY-GMV

Important note: the replacement of a power unit installed under Directive 95/16/EC - 81.2 with the new NGV-EK Power Unit does not require an amendment of the control panel and any additional adjustment for EN 81.2-A3.In case of substantial changes to the installation which requires an adaptation to EN81.2-A3, GMV can provide the product according to Annex A3.

For any questions, please contact our sales department.
