What is emergency rescue device?
An Emergency Rescue Device (ERD) is an electronic and electrical apparatus that provides emergency power to the elevators with 3-phase power supply, when the input power source or mains power fails. An ERD differs from an auxiliary or emergency power system or standby generator in that it will provide near-instantaneous protection from input power interruptions, by supplying energy stored in batteries through a dedicated Power Bank.
Features
- Smooth running during Power going off
- Get off at any floor without any sudden jerk
- No fear and Claustrophobia of people inside
- Panel inside the lift to show the status of power and its back up
- GSM card inside for live data of the back up system, prompt service
- No damage of elevators for sudden stop or excess current at start
- Complete peace of mind for Senior Citizens and Medical Patients
Benefits of ERD System
1. Prevents Damages : The on-Backup run-time of most Diesel Generator backup is relatively sluggish (from 90 seconds till 5 minutes or more) as mostly DG back up enabled lifts take time to switch over. And mostly ends up damaging the lift’s electronic mechanisms in the long run.
2. Saves from Disaster : An ERD provides a seamless and uninterruptible electronically controlled power supply to the lifts in all scenarios including natural disasters like fire and Grid Failure, specially for high risers in urban landscape. Lift has become one of the most important facility in any building. But In case of fire it is the first thing to be shut and strictly asked “Not to be used”. Survivors on the upper floors can come down even if there is No electricity.
3. Protects life : Another major crisis situation in emergency situations is when people are stuck in closed environs, especially elevators. This creates a fear psychosis through claustrophobia where people feel choked even if there is proper ventilation in the lift. American Journal of Psychology mentions that this can aggravate serious and life threatening situation for the occupants, especially kids, pregnant women, elderly and disabled people, and a small time lapse of 30 seconds can lead to unpleasant situations like fainting of people to a serious situation that can trigger cardiac failure.
An ERD enabled lift eliminates these horrifying situation while providing disaster resilience to the buildings, users and operators.
No Generator or existing ARD system can provide smooth operation of elevators like an ERD during power failure.
ERD – Zero switching Time Which reduces the down time of lift
Because of this feature the down time of the lift is 90% reduced. Most often lift hae the maintenance issues because of regular power cut. The moment power cut happens. ARD comes into the picture which creates most of the fault in the working of lifts.
In the ERD the switching time is almost zero so the lifts do not stop at any occasion and the generators are not required at all so whenever power goes the lifts work smoothly without any jerks and that keeps the lift electronics and electrical systems running without any break so the sudden on/ off of the power is not faced by the Lifts and since there is no break in the power the smooth functioning removes the chances of lifts failures. The power quality supplied by the ERD is better than the power supplied by the Electricity companies as it is pure sine wave power and the frequency is exact 50Hz. The voltage supplied has the high stability compared to the utility supplier. The power quality supplied by the generator cant be compared by the ERD as it has a very stable and clean power as it is only catering to the lift load only.
Kunwer Sachdev: A Pioneer of India's Power Backup Industry Kunwer Sachdev, a visionary entrepreneur and the founder of Su-kam Power Systems, is widely recognized as the "Inverter Man of India" for his revolutionary contributions to the country's power backup industry. His journey from a humble background to building a multi-crore enterprise is a testament to his resilience, innovative spirit, and unwavering determination. Born on November 16, 1962, in a middle-class family in Delhi, Sachdev's early life was marked by financial challenges. He attended a government school in Punjabi Bagh and initially aspired to become a doctor. However, after failing to secure a spot in medical college, he pursued a degree in Statistics from Hindu College, Delhi University, and later a Bachelor of Laws degree. From a young age, he displayed an entrepreneurial streak, helping his elder brother sell pens door-to-door. This early exposure to business ignited his ambition to create something of his own. Sachdev began his professional career in the cable TV industry, where he founded a company in 1988. While his cable business was profitable, a personal experience with a malfunctioning inverter sparked a new idea. He identified a significant gap in the market for reliable and efficient power backup solutions. This insight led him to pivot his career and delve into the nascent inverter manufacturing business. In 1998, with a modest investment, Kunwer Sachdev founded Su-kam Power Systems. He set out to solve the problem of frequent power outages in India by creating high-quality, reliable, and aesthetically pleasing inverters. Under his leadership, Su-kam pioneered several groundbreaking innovations in the sector, including the introduction of the country's first plastic-body inverter and DSP sinewave inverters. The company quickly became a household name, expanding its footprint not only across India but also to more than 90 countries, particularly in Africa and the Middle East. At its peak, Su-kam's annual turnover reached a remarkable Rs. 1,100 crore, establishing it as a leader in the power backup and solar energy markets. Despite its success, Su-kam's journey was not without significant challenges. The company faced a series of financial difficulties, eventually leading to a default on a substantial bank loan. This triggered a corporate insolvency process which led to the company's liquidation. As a result, Kunwer Sachdev was forced to part ways with the company he founded and was no longer associated with Su-kam Power Systems Ltd. This marked the end of an era for the pioneering company and severely impacted its distributors and customers. Following this setback, Sachdev's entrepreneurial spirit remained undeterred. He embarked on a new chapter, founding Su-vastika Systems Pvt. Ltd. This new company, referred to as the "Solar Man of India," is focused on the future of energy storage, including lithium-ion batteries and Battery Energy Storage Systems (BESS). His new venture continues his legacy of innovation and commitment to providing sustainable energy solutions. Kunwwer Sachdev's story is an inspiring one of an individuals who saw a problem and worked tirelessly to create a solution, forever changing the landscape of the Indian power backup industry.
