Coming Across Unfamiliar Problems with Refrigeration Equipment in Dubai

As a result of living in the age of technological and industrial innovation, there are many different types of equipment that perform the same function across any sector or industry, and the refrigeration industry is no exception to this rule. An unfortunate result of this is that sometimes even experienced personnel will come across unfamiliar issues while working on refrigeration equipment in Dubai. Although the systems work mostly the same way, small differences in the technology can create unexpected results during a routine procedure. This can be quite stressful when under pressure to figure out a problem. In the event of such a situation there are certain steps that can be taken to resolve this.

It is important to remember that no one person can be an expert in everything, and that extends to all the different designs and technologies employed in Refrigeration equipment in Dubai. Working for hours to figure something out that can instead be resolved with a phone call is a poor option as it is a waste of time and money, and would also reflect poorly on your reputation. The best option to ask for a ‘diagnosis’ is the manufacturer of the system you are working on. Well reputed manufacturers usually host a team of company trained technicians that will know what issues you are referring to. Another option is simply perusing the manufacturer’s online pages, where they might have forums where these problems can be discussed and solved as well as troubleshooting pages with common problems.

In case browsing through the website or phoning customer service helpline for help does not prove fruitful, one can always use other sources of experienced information. Although the manufacturer of the design remains the foremost expert on the equipment, there are many independent contractors and companies that have experience working on the same. They will, at the very least, be able to answer questions and provide insight that one would not have if they weren’t familiar with the specific manufacturer or design.

An unlikely place help may come from is the supplier of the parts making up the system. For example, even a parts manufacturer or CPVC pipes fittings supplier in Dubai may be able to offer insight if their products have played a role in the building of that particular equipment. In this way, many sources of information can be found that can help resolve unlikely and unfamiliar problems.

The Importance of Fire Rated Access Doors & Other Maintenance Tips for Fire Dampers

Fire dampers are an inescapably important part of a residential or commercial building’s HVAC system. Fire dampers have a fusible link attached to them that melt when the temperature inside the duct goes above the acceptable limit, which closes the fire damper down, thus preventing the uncontrolled spread of the flame.

Fire dampers need to be tested and maintained thoroughly. The initial test of the fire damper is done at the time of its installation, after which it is again performed the following year. According to regional laws and regulations, the fire damper can be tested every 4 - 6 years after the second test. In order to properly test, maintain, and repair these dampers, the presence of fire rated access doors is of paramount importance. These must be fitted in the duct system by air conditioning companies in UAE at the time of installing the ducts in the building.

Fire dampers are essential enough to the safety of the building’s inhabitants and property that any detection of improper functioning must immediately be met with repairs and/or replacements of faulty parts, like springs or crookedly attached panels.

The dampers and fire rated access doors must also be maintained regularly, checking for any signs of physical damage and alien objects and particles that could obstruct its proper functioning. Missing small parts and proper labelling is also a priority.

During testing, ensure that the fire damper is able to close completely to its intended extent.

If the fusible link is found to be damaged it should immediately be replaced by the same type of link. The parameters of the new fusible link, such as size, temperate range, and load limit should be double checked to ensure that they are the same as the link that is being replaced.

These measures are very important because a fire can occur at any time, and if one does occur while a fire damper is waiting to be repaired or is overdue on a maintenance check, not only will the fire spread uninhibited and damage a lot of property and take potential lives, but it will also leave the building owner’s highly accountable for negligent behavior.

A Brief Summary on Residential Air Diffusers: Swirl Diffusers & More.

Air diffusers are one of the many components and parts of a HVAC system that are sold by HVAc and ducting suppliers. Their primary function is to vent air conditioned air into a room. The most commonly spotted air diffusers in the region are the square ceiling diffusers seen in all centralized air conditioned systems in residential buildings, offices, and houses.

There are many different types of air diffusers. They are manufactured in a variety of designs and sizes, and the most common ones have fins that direct the outward flow of air in a certain way. The ceiling diffusers mentioned above are certainly very popular but other types of diffusers such as swirl diffusers and perforated ceiling diffusers perform the same in slightly different ways. The main reason so many different designs of air diffusers exist is because certain designs are more suited towards certain air replacement or introduction requirements. For example, in the pharmaceutical industry, an air diffuser that mixes clean and conditioned air with used air is highly undesirable. This is because the used air in plants such as these is full of contaminants and pollutants. An air diffuser that introduces air in such a way so as to replace the contaminated air is desired. 

Another reason swirl diffusers and the like are important is because they facilitate the even cooling or heating of an indoor space. Although diffusers are seen as ornamental covers for duct openings, their function is important and allows for even air distribution and ventilation. Another forgotten factor about air diffusers is that they, unlike window air conditioners for instance, provide a much quieter release of clean air. They do this by slowing down the release of air into the interior of a space and directing it to all areas of the room.

Air diffusers are usually easily installed and detached from the vents in residential and commercial buildings. However, they are not to be tampered with or have their flow obstructed because this can lead to poor air quality and might even damage the surrounding ductwork. If there is a need to remove a diffuser always be sure to replace or you might risk compromising your quality of life.

Ask Your PPR Supplier in Qatar Which Plastics are Safe to Use.

Plastic safety is a real issue across all imaginable industries and areas of use. For the longest time, people used glass or tin or even wood to store perishables and other items such as water, toys, even clothing. Since the invention of plastic came into being, more and more people turn to this material that is at once highly disposable and highly reusable at the same time. There is a danger to this kind of usage that many people are not aware of. Certain plastic materials are not to be reused and in some cases - such as a plastic water bottle being left in a hot car for hours or days - the plastic can leach toxins into the item or items it contains. Not all plastics behave this way so it is important to distinguish which should be used and which should not, which is why it is an excellent idea to ask your PPR supplier in Qatar if their products are safe to use and buy.

PPR or as it is sometimes called, PP, stands for Polypropylene. This plastic is a modified polymer that is frequently used by several manufacturers spanning multiple industries that product toys, baby bottles, even drinking straws and food containers. The production of PPR is of paramount importance to its safety. When purchasing items like baby bottles, always ensure that they are bought from reputable stores and suppliers. Although it may seem like a small matter for a small specialized business, any PPR supplier in Qatar should be able to show that their products are of a high quality, just the same as would be expected of a lifting equipment manufacturer in Qatar.

Good quality PPR has been shown to not leach harmful chemicals. Bisphenol A (or BPA) is a concern for many. There need not be a concern about this leeching into your water or food or other delicate supplies as long as you can check the recycling code. Only recycling code #7 has the potential to leach BPA. PPR can thus be safely used for several sensitive applications.

Why Your GARMCO Dealer in Dubai Uses PP - MD Pipes

Almost every Acoustic pipes supplier will let you know why they utilize PP-MD, or modified polypropylene for their products and supplies. Generally speaking, polypropylene is a highly diverse material that can be be modified to enhance or reduce certain features of the base material. This impressive thermoplastic polymer is popular because of its range of benefits that lends itself to its modified counterparts as well. Some of the general benefits include resilience, flexibility, and impact resistance which make it highly desirable for use in piping and drainage systems.

How Variable Air Volume System Manufacturers can Help You Reduce Energy Consumption

During a time of global climate crisis, all home and business owners are concerned with the rising price of energy, both economic and environmental. The vast majority of home and business owners who have an HVAC system installed in their place of work and living try to find ways to curb the amount of energy that is consumed by the heating and cooling equipment. This energy utilization is hugely heightened by the presence of severe temperatures during the summer and winter seasons. However, it is possible to control this energy use, and that is through regulating the flow of air inside an HVAC system, which is where variable air volume system manufacturers comes in. 

VAV systems offer owners of HVAC systems several advantages. The simplest kind of system manufactured by variable air volume system manufacturers supplies evenly heated and cooled air, the air flow of which is variable according to the requirements of the thermostat controlling the temperature of the zone the VAV system is serving. This kind of precise temperature control is one of its greatest advantages that allows for highly effective heating and cooling while conserving energy at remarkable rates. Another important distinction to make in the case of VAV air flow is the resulting dehumidification. Since the air flow is often reduced in many circumstances, the air is exposed for much longer periods of time than is normal to the cooling coils inside the HVAC system. Water vapour from this air condenses onto the coils and as a result dehumidifies the air, which creates a larger sense of comfort to the inhabitants of the indoor space.

The biggest and often the most coveted advantage of variable air volume systems is the fan control it incorporates. This fan control has evolved to serve the purpose of effective operation with even lower energy consumption. The newer models of electric fans can even serve as electric dampers in no small part due to their variable speed drives.

Incorporating a variable air volume system into one’s HVAC equipment is a necessity that accomplishes several goals. In the case that there is insufficient space to routinely incorporate the VAV system into a facility’s ductwork, flexible duct manufacturers can be called upon to correct this situation.

What You Need to Know about a UL Classified Fire Damper

Not many people who are not implicitly familiar with the industry will know the details about fire dampers, in fact, the general consensus is that it is a helpful part of the framework of a building in the event of a fire emergency. Fire dampers play an essential role in helping to curb the spread of fire. A UL classified fire damper is used to maintain the fire ratings of other fire rated walls, floors, etc. when they are interrupted by ducts.

Fire dampers shut close in the event of a fire emergency to prevent the flame from spreading further, especially through ductwork and eventually the supply ceiling diffuser in Dubai. This is possible because of a fusible link installed in the ductwork, which is designed to melt at 73.8 degrees Celsius, thus causing the UL classified fire damper to close. There are certain situations where the fusible link is designed to withstand hotter environments and respond to a temperature of 100 degrees Celsius. This is because some environments create a hotter “normal” temperature that is not indicative of a fire. Being an Underwriters Laboratories or UL classified fire damper means that the damper has been certified to carry a fire resistance rating which is measured in hours. This rating usually goes from 1.5 to 3.0 hours.

There are two major types of fire dampers. These are Dynamic Fire Dampers, and Static Fire Dampers. Dynamic Fire Dampers are used in situations where the building’s HVAC system’s blower will keep working in the event of a fire, or the Fans On mode. Static Fire Dampers are meant to used in emergencies when the HVAC system’s blower will be in Fans Off mode. This distinction is important because Dynamic Fire Dampers are specially designed to be able to function correctly against a strong air flow.

This post outlining the purpose, function, and types of fire dampers reveals how important they are to the structural integrity of a building’s fire safety standards. Highly rated fire dampers are responsible for containing a fire to as small a size as possible, preventing quick spread and heavy losses in densely populated areas.
