ZERO ENERGY - Solar Powered Elevators
ZERO ENERGY - AE3 ELEVATORS have been designed based on the most popular range and style of lifts that are used in modern day medium sized developments and small households. This makes it possible for any individual wishing to invest in an Eco friendly system that saves hundreds / thousands of Euros in electricity bills, to do so without a very large capital outlay. The main carachteristics of these systems are : Load Capacity - 6 Passengers / 450 Kgs Travel Speed - 0.60 m/s Max. Motor Power - 2.8kW In order to operate this standard type 2.8kW system as proposed, it is sufficient to have a Photovoltaic system that generates 1kWh. Considering 200 runs per day, each run for approximately 20 seconds, we require a total power supply of 4kW for the system. With 5 daily hours of radiation collection this system can generate 5kW, thus an excess of 25% over requirements that can satisfy any useage peaks and make up for any losses there might be in the system until rectified. LATEST TECHNOLOGY FOR ENERGY SAVINGS AND USEAGE OPTIMISATION Our top of the range control systems offer even more than we have described so far. An intelligent control system built into the control panel of the elevator, through a number of sensors positioned inside the lift shaft and on the cabin itself, and can thus adapt as following : - modification of travelling speed in case battery charge is less than required or daily average useage is being surpassed. - adaptation of power supply depending on the load present inside the cabin to make sure no excess energy is being used in the system. - regeneration and collection of the energy used by the system for braking during operation. - full lift operation even in case of power supply blackout since lift is independent from the mains supply. NOTE : An emergency power supply system can be provided in order for the lift to be operated in case of faults to the Photovoltaic system and / or the batteries. This can be left switched off and only used in these extreme cases to avoid any sort of inconvenience to the users. ENERGY SAVINGS COMPARED TO TRADITIONAL SYSTEMS
The advantages offered by this type of system are incredible. Furthermore the initial capital outlay for the purchase of the Photovoltaic system is recovered quite fast given the immense energy savings that are guaranteed by our ZERO ENERGY Package. The ZERO Energy package provides a very eco friendly system that operates using the latest generation gearless machines and the intelligent control system varies the consumption so when the cabin is not loaded the power used is lowered to around 1.5kW from the 2.8kW maximum power. Even when operating at full power (2.8kW) these lifts save as much as half the energy when compared to a similar traditional elevator system. Translated to figures this means that : - our permanent magnet gearless machines consume around 65% less energy than a hydraulic power unit and 50% less energy when compared to a traditional traction 2 speed drive. - peak starting current of our systems is 35% less than that of equivalent units - 3800 kWh / year less consumption when compared to a hydraulic elevator (same specs) - 1990 kWh / year less consumption when compared to a traditional electric elevator (same specs) - 2300 Kg CO2 / year less Carbon footprint reduction compared to a hydraulic elevator (same specs) - 1180 Kg CO2 / year less Carbon foot reduction compared to an electric elevator (same specs) - 20% of the energy used by the elevator is recovered through intelligent control and braking systems Also, apart from the system drive and machine, the cabin equipment and accessories are carefulyl selected to provide the most efficient and energy saving solutions possible : - LED lighting inside the lift cabin guarantees huge reductions over traditional halogen lights (an average of 450 kWh / year for a traditional lift - Intelligent control puts lighting and extractor fans on standby when system parked giving a further saving of around 300 kWh / year ALSO COMPARED TO A TRADITIONAL ELEVATOR YOU AVOID APPLICATION FOR 3 PHASE POWER SUPPLY THAT COSTS OVER 1000 EURO INCLUDING APPLICATION, ENEMALTA CHARGES, ELECTRICIAN FEES, ETC ..... NO HEFTY 3 PHASE METER MONTHLY CHARGES SINCE BACKUP SUPPLY REQUIRED IN CASE OF EMERGENCY CAN BE THE STANDARD TYPE SINGLE PHASE METER THAT IS USED FOR THE COMMON AREA LIGHTS, INTERCOM, ETC ... Should you require further information on these systems and / or require specific project quotations please contact our offices and we shall be glad to help you find the best package to suit your requirements.
