The use of high-quality pulleys and belts from well-known and reliable European companies ensures that there will be no interruption in air production.

Direct coupling compressors

Roll Air Company's D Series compressors offer high efficiency through direct power transmission between the air-handling units and the electromotor. In addition to reducing energy losses, direct power transmission reduces the depreciation of parts of air-handling units, electromotors, and maintenance costs.

The use of high-quality and distinctive couplings from a reputable European brand in the power transmission between the electromotor and the air-handling unit, as well as the design and manufacture of the coupling guard with the property of minimum thermal linear coefficient, which is the interface between the flange of the air-handling unit and the electromotor flange, the noise and vibrations to be minimized and the life of the bearings and seal shaft and the life of the air-handling unit, are guaranteed.

Air-handling units or Air End

One of the most important parts that distinguish a screw compressor is the use of a quality air-handling unit. In the design and construction of Roll Air Company compressors, the newest and most up-to-date European brands are used.

High efficiency, aeration, minimum depreciation and maintenance costs, no stopping of the device, stable and quality air production, and maintenance costs are the advantages of using these air-handling units.

In Roll Air compressors, due to the importance of preserving customers' capital, the engineering design of compressors guarantees this important point when turning on the device; in addition to the rotors being immersed in oil, the process of controlling the oil temperature and bringing it to the necessary temperature to create proper lubrication, especially in cold climates.

Air Compressor

Find the suitable rotary screw air compressor for your operations. Mark compressors have a wide range of oil-injected rotary screw compressor options to suit your business needs. From small installation right up to large industrial installations. Regardless of what type of compressor you need, we have options to match your requirements.

Internal fluid piping and fittings

Piping, hoses, and fittings for fluids, including oil and air, are all of the best European brands and are made of flexible stainless steel. Because it does not have the possibility of fragility and changing the shape of the cross-section, fluid clogging does not occur. Due to the passage of time and temperatures, these hoses do not become brittle. One of the properties of using stainless steel hoses is that there is no corrosion and entry of metal particles due to corrosion and decay into the air-handling unit, and high-quality fittings minimize oil and air leakage; in addition, it will be easier to assemble and disassemble.

Oil-air separator unit

A special and creative design combined with experience and knowledge has led to the design and construction of a distinctive oil separator unit.

This valuable design is such that a large percentage of air-oil separation is done before reaching the separator filter. This important parameter leads to an increase in the life of the separator filter and the high quality of the output air.

Oil cooler and aftercooler

Fin and tube aluminum heat exchangers from a reputable European brand/with a special design have made it possible to provide a higher heat level and efficiency per surface unit. The design and engineering unit of Roll Air Company has included a combination of oversized converters in terms of heat level with low-speed fans in the design of screw compressors to optimize the temperature operation of the compressors.

Among the advantages obtained based on this choice and design, the following can be mentioned:

  • Optimum oil temperature in different climatic conditions.
  • The low vibrations of the fans due to the low rotation, the fans' light blade, and the dynamic balance lead to fewer repairs.
  • Optimized and directed airflow and less noise
  • Due to the high efficiency of the converter in the aftercooler section, the produced air is cooled as much as possible (relative to the temperature of the working environment of the compressor).
  • This effect significantly increases the working efficiency of refrigeration dryers and consumes less electrical energy in them, and as a result, the quality of natural air.
Since the temperature of the oil in the internal circuit of the compressor is under control, we will see the minimum output of oil vapors in the air outlet of the compressors.

 

Body and chassis of the device

One of the important advantages of Roll Air compressors is easy to access all parts.

This level of access allows maintenance technicians to easily disassemble entire doors and even cabinets.

The furnace color, the use of the highest quality colors, and the elegance in the construction of the cabinets, which is completely done in the Roll Air Company, have led to the presentation of a distinctive image with elegance. For sound and thermal insulation, the device cabinet is fully equipped with insulation.

The result of compressing air is the production of thermal energy; in other words, 90% of the 100% electrical energy that enters a compressor device is released as thermal energy. Do you know where this thermal energy goes?

The exhaust air removes part of this thermal energy from the compressor, and a large part must be discharged inside the compressor.

Therefore, due to the huge amount of thermal energy that is continuously produced by the compressor, we need an intelligent and engineered design for the ventilation inside the compressor cabin.

The design of the location, dimensions, and type of air inlet valves, as well as the design of air discharge fans and how to separate and direct the air out of the compressor, is an important point that the engineering design unit of Roll Air Company has correctly understood and implemented. To ventilate this large amount of thermal energy, continuous air circulation is needed, and the parameter of the air entering the compressor cabinet being free from dust led to the use of air inlet filters at the entrance of the cabinets.

Easy cleaning inside the device was an important point that led to the design of an integrated and closed chassis that can easily and completely clean the floor space inside the compressor. The design of the chassis and body, the use of the best spare parts, and the design based on eliminating vibrations have resulted in providing a product that does not require bolts and shock absorbers during installation.

Optimal energy consumption

Roll Air Company's social responsibility towards the future and the surrounding world is included as a value in the whole body of this group. Respecting and paying attention to this value in the production sector leads to producing screw compressors with minimal output oil, which is essential to preserve the environment.

Trying not to waste energy and prevent global warming was another motivation to design and produce variable speed compressors that lead to a reduction in energy costs and repairs and maintenance. Thanks to the variable speed control technology, the produced air capacity of the compressors can be made a function of the amount of air requested. This technology prevents the loss of electric power during unloading or no load of compressors. At the beginning of the start-up, it is gradually introduced into the circuit by controlling the frequency of the input electricity to the electromotor of the low-speed compressor. This point causes the peak intensity of the flow to not be applied to the motor. There is no effect on the power of the electricity distribution network.

Variable speed compressors adapt the rotation speed of the electromotor to the required amount of air, and simply by producing the exact amount of air used in the production lines, they help to reduce energy consumption and increase efficiency. Due to not applying the initial torque during start-up, we will see a decrease in the depreciation of the bearings of the air-handling unit and the electromotor, the pressure curve of the produced air is modified to constant pressure, and the pulses of the quantity of produced air are greatly reduced.

Electrical panel and electrical equipment and electromotor

In industries and production units that use compressed air, compressed air is as important as electrical energy, and even a momentary stoppage of compressed air can lead to heavy losses. Therefore, the selection of electrical elements in terms of quality and quantity, as well as the design of the electrical circuit and the design of the electrical panel box in terms of ventilation and protection from the contaminants in the air and the surroundings, is very important and it is a key point to guarantee the device's flawless and non-stop operation.

In addition to selecting and installing the best electrical components and electromotor from the world's most reputable brands, Roll Air Company offers the possibility to remotely control and monitor the compressor upon request.

Filtration of air entering the air-handling unit

In businesses, it is very important to produce a product at a competitive price. This happens when it is possible to concentrate as much as possible on the energy consumption and spare parts of machines, as well as to increase the lifespan of production-related devices. The life of Roll Air Company depends on the life and development of its customers, and this is why we help to preserve the customers' capital by using the best spare parts and design based on the long life of the devices.

The screw compressors of this company are equipped with a closed inlet suction filter and with a propylene housing that is resistant to shock and corrosion-resistant and designed for harsh working conditions, such as in places with high dust and even high temperature, and the air inlet ensures the being free of the air from suspended particles and dust in the air-handling unit. Among the advantages of this filtering, the unit can be mentioned long life due to the use of efficient and reliable elements and low-pressure drop.

The use of an efficient air filter does not allow dust to enter the air-handling unit, and following this point will prevent dust from entering the bearings, rotors, heat exchangers, and other parts related to air that are not lubricated, as well as increasing the lifespan of the oil and the air-oil separator filter and oil filter guarantee the longevity of the bearings.
