How to Enhance a Compressor's Energy Efficiency?

An air compressor’s efficiency often comes with maximum utilization of the energy resources and compressed air.

Due to the non-usage or leakage of the compressed air, energy gets wasted in the whole process. Thus, it is rather necessary to enhance your compressor’s energy efficiency.

Here are some of the ways to ensure efficiency:

• Examine the whole usage: You must have a detailed understanding of the whole compressed air system, including the compressors, the air supply lines, end uses etc. This gives a comprehensive idea of how your machine works and what are the possible issues causing troubles like:

1. Leakage
2. Pressure Drops
3. Air Storage
4. Over Pressurization
5. Condensation Drains
6. Poor Management of the compressor system

• Verify CFM Output: Several issues on the piston rings and premature modulation of different compressors can result in lower amount CFM output much lesser than what it is supposed to produce. You could do an examination of the inaccuracy of the adjustment valves and change them if they are the major cause of the issues. 

• Reduce Pressure Drops: During the service life of an air compressor, the pressure drops must not exceed 15 psi. When it becomes more than 10 per cent you ought to check the whole distribution system and find the cause of this excessive pressure drops. And you could:

1. Install an air distribution piping that is big enough to reduce pressure drops
2. Install a pressure regulator
3. Install inlet air filters that remove all the dirt that restrict the airflow

• Check leakages: You should always conduct regular inspections on the leakages while and off production times to ensure the overall leak rate. An ultrasonic leak detector and professional auditor are excellent to find and fix the leakages.

• Check V-belts: Frequently ensure that the V belts are tight enough because loose belts can reduce the efficiency of the compressor.

A regular inspection of all these things is tremendously important in the energy-saving and efficiency of an air compressor reducing energy wastage. The best compressor overhauling companies in Sharjah and other parts of the world provide great services in checking your compressor and repairing it in a way that gives maximum output without any possible wastage. 

3 Basic Problems of Chiller Systems and their Possible Causes

Even after regular checkups and maintenance of chiller machines, they can face issues and degradation over the years due to the continuous workload or damages on different parts of the system.

Whenever a client calls in to report an issue of the machine, the respective HVAC chiller services take an immense effort in reaching down to the customer and repairing it for better performance.

There are three basic problems that are usually seen in chiller machines and here are some of the most possible reasons behind these failures.

• Chiller Machine does not power on

• One of the most common causes of a machine not turning on would be a loose contact or an improper voltage line that gets high and low at times, whereas a chiller requires a constant voltage source.

• In cases of three-phase units, an incorrect phase connection could result in this problem.

• There is a possibility of the circuit or fuse to be blown or tripped that cuts the current supply.

• It could also be a simple mistake of not noticing that the machine is in an “off” position.

• Insufficient Fluid Flow

• Constant fluctuations in the voltage can result in this issue.

• The fluid stored in the reservoir would be insufficient for a powerful flow.

• There is a high chance that the process line, process valve, fluid filter etc. are pinched or blocked with dirt restricting the fluid flow.

• This issue can also arise if the process piping is too small when the requirement is higher.

• A failure of the pump. 

• Insufficient Cooling Effect

• Fluctuating voltage sources may cause this issue of inadequate cooling. 

• The air filter or the condenser could be clogged.

• The coolant fluid within the machine could be unsuitable for temperature requirements.

• The earlier heat transferring properties of the coolant fluid must have deteriorated over the years.

• There could be a refrigerant leak.

• The evaporator could be filled with ice.

These three are the most common problems seen around chiller machines that trouble the effective functioning of the system. The best chiller repairing in UAE and other parts of the world are definite in providing their qualified services in repairing and fixing all the chiller related problems for better functioning of the machine in the future. 

Different Applications of Industrial Chillers

 

Industrial chillers are these types of chiller machines mainly used in industrial production sites.

Within industries, due to the production processes there arise high temperatures and the machines are at high risk of overheating.

There comes industrial chillers at these production industries that use vapour compression or absorption method for transferring the heat produced inside and replaces it with cooling effect.

They are specially designed in such a way that they can cool down any kind of equipment, thus are in high demand at the industries.

Here are some of the areas or fields that make imminent use of industrial chillers:

• Plastic Industry: During the production of plastic products, the machinery tends to produce heat and chillers are at rescue cooling the machines. This cooling effect is extremely important as it saves a lot of energy and prolongs the life of production machines. They are also involved in the process of cooling the hot plastics readily produced. 

• Beverage Industry: Beverages comprises a wide range of varieties that include milk products, soft drinks, breweries etc. Beverage industry involves all these processes of pasteurizing, cooking and mixing that emits a lot of heat that must be cooled for the better performance of machinery and fine quality of the end products. 

• Printing Industry: In the printing industry, a lot of plastic rolling and friction happens that give rise to heat that definitely requires a chiller unit. They are also imperative for cooling the papers that come out of the ink drying machine. 

• Rubber Industry: Chillers are also necessary at the rubber industries for cooling the rubber mixtures and the entire rubber mills by utilizing the water temperatures. 

• Laser and Cutting Industries: In these industries it is the overheated power supply that provides laser and light requiring constant cooling in order to function efficiently and effectively. 

• Medical Industry: Medical industry has the usage of a wide range of equipment and plastic products within the hospitals. Even the MRI Scanner used to diagnose and treat different disease conditions emits a lot of heat that must be managed with the help of a medical chiller. 

All the above mentioned industries use chiller services for maximum production and saving their costs.

Chiller systems well- known for cooling the overheated production processes are indeed a necessity in each and every industry for the crucial merits it offers.

The best chiller services in UAE and other countries provide quality installation of industrial chillers at your workspace for increased productivity. 

How does Air Curtains help in Insect control?

 

Air curtains are usually known to be this cooling device that uses the compressed air as their primary source and balances the temperature within the industries and companies.

One of the significant features of air curtains is that they can effectively help in keeping the pests, flies and other malicious insects at the bay of your company door.

Dan Clark, a renowned housefly pest control expert, claims that although glue boards and ILT’s are great reactionary devices for the pests that already gained access within, an air curtain is more of a proactive approach for the problem.

These air curtains are installed above the door opening and they emit high velocity, invisible air streams that act as barriers against the flies trying to enter the building. 

These types of Pest/Insect control air curtains are mainly used in the following commercial fields of:

• Food processing plants

• Dairies 

• Bakeries

• Bottling plants

• Restaurants

• School cafeterias

• Supermarkets

• Hospitals 

• Pharma industries

These air curtains give effective results no matter of their installation vertically or horizontally, inside the doorway or outside the doorway. The most prominent need is that the whole doorway must be wholly protected against the entry of insects, a minimal amount of gap is sure to attract flies into the building. 

Installing air curtains inside or outside of the door depends on the needs and requirements of the customers as they have different functionality. Air curtains inside would be preferable in areas of heavy winter, as they help in maintaining the temperature within the building and stop the influx of cold air from the outside along with the prevention of airborne insects.

In some cases air curtains are best outside as they might be an odour within the building that has higher chances of attracting insects into the building. So in order to avoid that it is best to install the air curtains on the outside. To achieve a high level of protection of the doors and buildings one may have to use powerful air curtains of UAE or other parts of the world for longer life and enhanced performance.

6 Major Types of Air Compressor Control

In the production of air compressors, it is important to design the major air compressor controls as they help in regulating the delivery of compressors in accordance with the demand.

There needs to be a control over the discharge pressures for better energy usage and much more.

The control strategies are very much essential for the better functioning of the system and high performance.

The control systems largely depend on the type of compressors used.

The system with multiple compressors are in need of heavy control strategies much greater than one that requires only one compressor with a steady demand.

Here is the list of all the six major types of compressor controls:

• Start/Stop: This is the most basic form of compressor control that switches on and off the motor, facilitating discharges from the compressor in accordance with the pressure signal. It cannot be used in systems that require frequent cycles, because consequent starts will cause overheating. Thus are more applicable in systems with low cycle rates.  (reciprocating and rotary screw compressors)

• Load/Unload: This control system is also widely known by the name- Constant Speed Control, because in this the motor never stops, it runs continuously, but unloads the air compressor when the desired pressure is met. It reloads again with a low discharge pressure for optimal working. (reciprocating, centrifugal, and rotary screw compressors)

• Modulating Controls: Also known as Throttling or Capacity Control, as they modulate the compressor output in dire accordance with the flow required. This important modification or control is done by shutting the inlet value, so that inlet air stops entering the compressor and it can safely unload the consisting output. (centrifugal and rotary screw compressors)

• Dual/Auto dual Controls: In dual controls, it allows a system that offers a selection between start/stop or load/unload in small reciprocating compressors. Whereas the auto dual control in rotary screw compressors, all modulations automatically work according to the pre-set time. At a fixed time the reduction of the capacity happens then unloading of the compressor and then stops the air compressor for a pre-set time.

• Variable Displacement: This control system allows a gradual reduction of the air compressor discharges or outputs without reducing the inlet pressures through various valves. This scheme has a relatable connection with motor power consumption and loaded capacity. (Reciprocating and rotary screw compressors)

• Variable Speed Drives: In accordance to the system signals these control schemes are efficient enough to adjust the air compressor capacity by varying the speed of the motor that in turn runs the compressor. 

All these six major air compressor controls are seen in different types of air compressors as per the requirements.

They effectively separate the two environmental temperatures.

The moment you enter inside a mall, you can feel the cooling effect in contrast with the heat that was felt outside.

This is due to the operation of air curtains.

Air Curtains in Dubai, helps in the installation of air curtains in restaurants, hospitals and commercial industries in Dubai.

Apart from the industrial benefits of air curtains like the energy savings, increased safety, business profitability and increased productivity, air curtains do have certain added advantages such as:

• Saving Space: By installing air curtains over the vestibules, the company saves a lot of energy indeed. There also adds the benefit of space, air curtains maximise floor space. Air curtains are usually installed with minimum cost and they are neatly placed on top of the doorways, without taking any extra space.

• Design Flexibility: Installing air curtains will not require a change in the design of the building. They stay as an unseen barrier against the outside elements. They are very much useful in the main entrance doorways of the companies, where the doors are often kept open, or are in need of opening frequently throughout the day.

• Employee Comfortability and Satisfaction: Air curtains help to maintain the stable environment inside the firm. They use less supplemental heat than vestibules, increasing the comfortability of the employee. They maintain the temperature in all kinds of weather and help to keep the traffic flow unhindered.

• Prevents foreign contaminants from entering inside: Air curtains limit the entrance of airborne contaminants like dust, pollutants, bad odours etc into the firm. They also restrict the appearance of insects and pests from the outer air.

• Pay-back period: All the energies and the installation costs that are being saved adds up to a potential amount. The amount can be a three-year payback for an air curtain, when compared to the costs of installing a permanent and expensive construction. 

These are the five added advantages that are provided by the air curtains apart from the other technical benefits.

Best air curtains in Dubai install the air curtains considering the door characteristics, ventilation and the other conditions. 

Blast Freezers: Why do you need them?

Blast freezers are cooling systems that are used in food production areas for food preservation.

They are also known as shock freezers.

The basic idea behind the principles of blast freezing is to reduce the temperature of fresh food items rapidly in order to freeze them.

This is done to stop bacteria from deteriorating the food products, thus preserving them for a longer period of time.

Thus all the food businesses are in heavy need of refrigeration applications to ensure the quality of the food items by keeping it fresh and safe.

HVAC chiller services in Dubai, Sharjah, etc provides quality services in the installation of blast freezers for the food businesses around. The major advantages of blast freezers are:

• Hygienic factor of food products: All kinds of food items have the presence of microorganisms in them. When food products are stored in the wrong temperature the microorganisms get reproduced and spoils the food completely. Blast freezers facilitate a rapid lowering of temperature thus making the microorganisms sterile and unable to function.

• Preserves moisture of the food: When food items are stored in freezers about 85.5% of the moisture content can be preserved. It helps the food items to maintain its firm shape, flavour and nutrition value. It also prevents the growth of microcrystals formed in between the cells. Thus, all together the temperature maintenance of the freezer gives healthy, tasty and fresh food.

• Beneficial in commercial kitchen: In case of a large commercial kitchen, the chefs may have to face lots of unexpected orders. In such a situation blast freezers help them in proper planning and preparing of food ahead of time. The customers don’t have to wait for a long time, everything including the service can be properly managed. 

• Reduce food wastage: With the help of freezers, food items are preserved for several days. These food items are sure to be ruined without freezers.  Thus, using best blast freezers can reduce the amount of food items wasted.

Blast freezers are best in fulfilling the expectations of food standards.

There is no hope for bacteria to contaminate the food items frozen in blast freezers.

The top HVAC chiller services in UAE and other parts of the world helps in installing the best blast freezers according to the client’s business needs.
