With 38 models ranging from 71 CFM to 5067 CFM, frick gas compressors are available for almost every industrial refrigeration need. These Frick compressors are designed for use with ammonia, halocarbon, and hydrocarbon refrigerants. The easily manageable, compact package gives you more space and lowers construction costs to save you money. Manufactured to meet your specific requirements, the Frick Compressor Package is reliable, accessible and easy to service. Screw compressors are capable of converting large quantities of shaft power into gas compression in a relatively small space and a mass is required to effectively dampen these relatively high-frequency vibrations. Firmly anchoring the compressor package to a suitable foundation by proper application of grout and elimination of piping stress imposed on the compressor is the best insurance for a trouble-free installation. Use only the certified general arrangement drawings from Frick to determine the mounting foot locations and to allow for recommended clearances around the unit for ease of operation and servicing. Foundations must be in compliance with local building codes and materials should be of industrial quality. The floor must be a minimum of 6 inches of reinforced concrete and housekeeping pads are recommended. Anchor bolts are required to firmly tie the unit to the floor. Once the unit is rigged into place (See RIGGING and HANDLING), the feet must then be shimmed in order to level the unit. The shims should be placed to position the feet roughly one inch above the housekeeping pad to allow room for grouting. An expansion-type epoxy grout must be worked under all areas of the base with no voids and be allowed to settle with a slight outward slope so oil and water can run off of the base. They should run parallel to the package feet and support the feet for their full length. 2. The compressor unit feet should be continuously welded to the system base at all points of contact. 3.
The compressor unit should not be mounted on vibration isolators in order to hold down package vibration levels. 4. The customer’s foundation for the system base should fully support the system base under all areas, but most certainly under the I-beams that support the compressor package. It may be necessary to use rubber or spring isolators, or a combination of both, to prevent the transmission of compressor vibration directly to the structure. However, this may increase package vibration levels because the compressor is not in contact with any damping mass. The mounting and support of suction and discharge lines is also very important. Rubber or spring pipe supports may be required to avoid exciting the building structure at any pipe supports close to the compressor package. It is best to employ a vibration expert in the design of a proper mounting arrangement. In any screw compressor installation, suction and discharge lines should be supported in pipe hangers (preferably within two feet of vertical pipe run) so that the lines won’t move if disconnected from the compressor.

Present in 18 countries, in America, Europe and Asia, and with massive growth in China, Bimbo brings to the market approximately 5,000 products and 100 well-known trade marks.Recently, Bimbo selected the Hazpan plant and granted Danfoss authorization to implement an energy saving system on one of its ammonia compressors. In this case, a 200kW CT7 Frick screw compressor, which represented an excellent opportunity for energy savings, due to the large number of compressor units installed in Bimbo plants, and owing to their requirements for motors. A slip valve is basically a valve that regulates the gas flow, maintaining the compressor suction pressure. However, using a frequency converter to control the speed is becoming more and more common. The compressor’s energy consumption can be optimised and the compressor capacity will vary proportionally to the speed. Although the CT7 Frick compressor works for long hours, power consumption never reaches close to 100 load. Normally, an a.c. motor on no-load uses one third of its rated current, and in the case of a screw type compressor, when on no-load, the current usually reaches a value close to 40 of the motor’s rated current. Now the successful experience is becoming standard in other Bimbo plants. The monthly savings is USD 1,155, meaning a return on investment in 24 months maximum.
The compression of one pair of cavities is highlighted: air is sucked in through the intake port, compressed (shown by the color change from cyan to red) and released through the outlet port. These compressors are common in industrial applications and replace more traditional piston compressors where larger volumes of compressed gas are needed, e.g. for large refrigeration cycles such as chillers, or for compressed air systems to operate air-driven tools such as jackhammers and impact wrenches. For smaller rotor sizes the inherent leakage in the rotors becomes much more significant, leading to this type of mechanism being less suitable for smaller compressors than piston compressors.This also allows screw compressors to be significantly quieter and produce much less vibration than piston compressors, even at large sizes, and produces some benefits in efficiency.Click here for the animated diagram In a dry-running rotary-screw compressor, timing gears ensure that the male and female rotors maintain precise alignment without contact which would produce rapid wear. In an oil-flooded rotary-screw compressor, lubricating oil bridges the space between the rotors, both providing a hydraulic seal and transferring mechanical energy between the rotors, allowing one rotor to be entirely driven by the other. Gas enters at the suction side and moves through the threads as the screws rotate. The meshing rotors force the gas through the compressor, and the gas exits at the end of the screws.The working area is the inter-lobe volume between the male and female rotors. It is larger at the intake end, and decreases along the length of the rotors until the exhaust port. This change in volume is the compression. The intake charge is drawn in at the end of the rotors in the large clearance between the male and female lobes.
At the intake end the male lobe is much smaller than its female counterpart, but the relative sizes reverse proportions along the lengths of both rotors (the male becomes larger and the female smaller) until (tangential to the discharge port) the clearance space between each pair of lobes is much smaller.However, some leakage is inevitable, and high rotational speeds must be used to minimize the ratio of leakage flow rate over effective flow rate.Usually the male rotor has fewer lobes than the female rotor, so that it rotates faster.As horsepower increases, there is a substantial economy of scale in favor of the rotary-screw compressors. As an example, a 250 HP compound compressor is a large piece of equipment that generally requires a special foundation, building accommodations and highly trained riggers to place the equipment. On the other hand, a 250 HP rotary-screw compressor can be placed on an ordinary shop floor using a standard forklift. Within industry, a 250 HP rotary-screw compressor is generally considered to be a compact piece of equipment.While there are high pressure rotary-screw compressors, within the compressed air community, the upper pressure limit is generally around 125 PSI.Normally, rotary-screw compressors are mounted using standard rubber isolation mounts designed to absorb high-frequency vibrations. This is especially true in rotary-screw compressors that operate at high rotational speeds. Still others are rated in Cubic Feet per Minute (CFM).Lysholm developed the screw compressor while looking for a way to overcome compressor surge in gas turbines. Lysholm first considered a roots type blower but found this was unable to generate a high enough pressure ratio. In 1935, Ljungstroms patented a helical lobe screw compressor which was then widely licensed to other manufacturers.Flooding provided both cooling, which allowed higher pressure ratios, and the elimination of timing gears.
They are best applied in applications that have a continuous air demand such as food packaging plants and automated manufacturing systems although a large enough number of intermittent demands, along with some storage, will also present a suitably continuous load. In addition to fixed units, rotary-screw compressors are commonly mounted on tow-behind trailers and powered with small diesel engines. These portable compression systems are typically referred to as construction compressors. Construction compressors are used to provide compressed air to jack hammers, riveting tools, pneumatic pumps, sand blasting operations and industrial paint systems. They are commonly seen at construction sites and on duty with road repair crews throughout the world.They usually have lower maximal discharge pressure capability as a result.However, this does not preclude the need for filtration, as hydrocarbons and other contaminants ingested from the ambient air must also be removed prior to the point of use. Consequently, air treatment identical to that used for an oil-flooded screw compressor is frequently required to ensure quality compressed air.The oil is separated from the discharge stream, cooled, filtered and recycled. The oil captures non-polar particulates from the incoming air, effectively reducing the particle loading of compressed-air particulate filtration. It is usual for some entrained compressor oil to carry into the compressed-gas stream downstream of the compressor. In other applications, this is rectified by the use of receiver tanks that reduce the local velocity of compressed air, allowing oil to condense, drop out of the air stream, and to be removed from the compressed-air system by condensate-management equipment.Reaction-hardening two-component epoxy resin paints are resistant to PAG oil.
This allows much smaller rotors to have practical efficiency since at smaller sizes the leakage area does not become as large a portion of the pumping area as in straight screw compressors.This device uncovers part of the rotor and proportionately reduces capacity of the machine down to typically 25 of the compressor's capability, thereby unloading the compressor. This scheme is utilised by nearly all industrial air-compressor manufacturers.However, for applications where it is not readily possible to frequently cease and resume operation of the compressor (such as when a compressor is driven by an internal-combustion engine and operated without the presence of a compressed-air receiver), modulation is suitable. The continuously variable production rate also eliminates the need for significant storage if the load never exceeds the compressor capacity.In automotive superchargers, this is analogous to the operation of a bypass valve.The screws run at high speed and with closely engineered tolerances. Each rotor is radially symmetrical, but laterally asymmetric. The Whipple-manufactured male rotor has three lobes, the female five lobes. The Kenne-Bell male rotor has four lobes, the female six lobes. Females in some earlier designs had four. By comparison, Roots blowers always have the same number of lobes on both rotors, typically 2, 3 or 4.With later technology, manufacturing cost has been lowered while performance increased.While some centrifugal superchargers are consistent and reliable, they typically do not produce full boost until near peak engine rpm, while positive displacement superchargers such as Roots type superchargers and twin-screw types offer more immediate boost. In addition to this, twin-screw superchargers can keep the reasonable boost to higher rpm better than other positive displacement supercharges.Retrieved 9 July 2016.
