3 Things You Need to Keep in Mind Before Installing an Elevator

With multi-storey buildings being made all over the world, elevators have become the spine of every such structure. They provide structural support and ease the going up and coming down for people. Bangalore too is one of the fastest-growing economies in India, where the number of high-rise buildings is growing as well. However, when it comes to installing an elevator in a Bangalore high-rise, there are several factors that one must keep in mind before choosing one.

Safety

There are different grades and types of elevators available in the market. The first thing that you need to keep in mind while choosing an elevator is the safety of the people using it. With careful planning and proper installation, choosing the right type of elevator for your building is also important. For choosing the right type of lift, you will have to factor in the number of people who would use it and whether a particular type of elevator would be enough to bear the footfall of the building without causing long wait times.

Design

Though safety is always going to be the first priority for the builder, one should also keep the aesthetic aspect in mind. If you have built a new and modern office, you will have to check for the latest and trending designs, so that the lift does not take away the charm of your office or building. There are a lot of manufacturers that offer some of the best designs for elevators in Bangalore. So, you will have a lot of choice when it comes to choosing.

Every building has a different footfall, and this becomes a very critical point to keep in mind. This factor impacts a lot of things, from the design to the type of lift that will be best suited for your establishment.

Keep these 3 major aspects in mind while planning on installing a lift in any building for unhindered convenience and durability in the long term.

Reasons Why You Need an Air Curtain at Your Restaurant

As a restaurant owner, you may face many challenges, some of which are being able to keep your customers safe, being able to save energy, and keeping pests outside your premises. While there will be many other challenges for you to solve, the aforementioned are some that can easily be dealt with if you install an air curtain by Mitsubishi Electric India. An air curtain is placed over a door in order to create a powerful air seal over the opening.

Here are some of the top reasons why you should consider getting an air curtain by Mitsubishi Electric India installed at your restaurant:

Increases Customer Comfort

Keeping the customer happy is something that is imperative for any business. Maintaining a comfortable temperature inside the premises is a very important part of ensuring customer satisfaction and an air curtain can help you do that. The strong air-flow ensures that the warm or cool air inside remains inside. At the same time, the temperature is not affected by the outside weather.

Reduces Energy Costs

Keeping the door open is a proven way of attracting customers, but the open door can also lead to the hot or cold air outside getting in. This makes it very difficult for the restaurant’s air conditioning system to maintain the temperature it is supposed to. This, in turn, leads to the system overworking and generating high electricity bills. An air curtain, on the other hand, creates an invisible barrier, preventing the inflow and outflow of air, which protects the temperature inside. This means less wear and tear for your heating or cooling system and lesser electricity costs.

Promotes a Clean Environment

Air curtains restrict flying insects and other pollutants like traffic fumes, pollen, and dust from getting inside the restaurant. Creating an effective seal by re-circulating the facility air across a doorway, they make it harder for the outside air and pollutants to penetrate the air curtain.

Reduces Strain on Existing Heating or Cooling Systems

As mentioned before, with an air curtain, there is less stress on your heating or cooling system, which helps it last longer. Less usage of the air conditioning system also helps increase the lifespan and functionality of the same.

The Different Types of Elevators

Elevators form an integral part of our lives. In our society, which is replete with sky-high buildings, elevators are not only symbolic of luxury but an absolute necessity. Nowadays, there are various types of elevators available in the market, with each of them designed to suit a particular requirement.

Elevators can broadly be classified into two categories, which are mentioned below-

Traction Elevators

Traction elevators are the most commonly used and highly reliable elevators, in which the car is raised and lowered by steel ropes or belts on a pulley system. In comparison to other elevators, they use lesser energy and ride smoother. They are primarily designed to serve mid-to high-rise buildings and are driven by alternating current (AC) or direct current (DC) electric motors. They are further classified into three types-

• Geared Traction Elevators: These use a large-sized motor with a reducer and gears.
• Gearless Traction Elevators: These use permanent magnets for their operations.
• Machine-Room-Less (MRL) Traction Elevators: These elevators do not have a dedicated machine room above the elevator shaft.

Hydraulic Elevators

Hydraulic elevators are highly efficient elevators that are powered by a hydraulic jack, which are fluid-driven pistons travelling inside a cylinder. These elevators use the compression of fluids to generate movement. The sole objective of using hydraulic elevators is to transport heavy industrial loads such as machinery and other equipment. These reliable elevators are quicker and less expensive to install and occupy much less space in a building. They can further be divided into the following types-

• Holed Hydraulic Elevators: In holed hydraulic elevators, the hydraulic cylinders are placed inside a drilled hole.
• Hydraulic Elevators devoid of holes: This type of elevator doesn’t make use of drilled holes.
• Roped Hydraulic Elevators: Roped hydraulic elevators use cables and a piston attached to a sheave for transporting the load.
• Machine Room-Less (MRL) Hydraulic Elevators: In these types of elevators, the hydraulic lift mechanisms are located in the hoist-way instead of a separate machine room.

Further, with the advancements in technology, the costs involved in the manufacture of elevators have reduced considerably, making them quite affordable. Thus, you can install them easily without worrying much about your budget.
