But that’s not good enough for BITZER quality standards, which is why we manufacture ACP systems only in perfect conditions at our manufacturing sites and can thus fulfil even the most demanding standards.’ BITZER also simplifies and accelerates installation by supplying a turnkey compact screw compressor unit. In concrete terms, the ACP systems optimally temper the factory’s 2°C refrigerated storage facility, the –5°C spiral chiller and the –18°C freezer facility at all times. Aholanmäentie 88, 49630, Hamina, Vehkajoki, Finland, Ammonia сompressor unit with cooling capacity 397 kW, Compressor units for petrochemical industry, Compressor units for unloading and loading of liquefied gases. A P28AN or P28DN control used for ammonia service must be mounted separately from the electrical cabinet. The process most commonly used is the Harber-Bosch method. Currently, ammonia compressors always open type. The refrigeration capacity of a compressor is the product of the evaporator enthalpy rise and the compressor mass flow rate. c = capacity (Btu/min) v = volume of gas entering compressor (ft 3 /lb) NRE = Net Refrigeration Effect (Btu/lb) Heat of Compression . Strength was also an important factor: thanks to the three powerful BITZER screw compressors per ACP unit, the system offers maximum operating reliability for the temperature-sensitive goods – around the clock, 365 days a year. Refrigerant: primary ammonia (R717), secondary CO 2 (R744) WHERE TO USE. With the ACP.85 and the ACP.95 series of screw compressor packages designed specifically for ammonia, BITZER has expanded its offerings to meet the demands of the industrial and commercial markets. Capacity control steps per cylinder. Q = (16,649FT3/h x 62.414lb/ft3) x 1.0007643BTU/lb.F x (53.6F – 42.8F) Giving us a cooling capacity of 8,533,364BTU/h. Our capacity table is based NH3 Refrigerant NH 3 (ammonia) kW at +10ºC/+40ºC 1450,4 kW at 0ºC/+40ºC 971,5 kW at -5ºC/+40ºC 780,1 kW at -10ºC/+40ºC 627,7 Electromotor kW 200 at 1489 On steel base frame Remarks Rotor nl 4RN315L04A7 Electromotor BITZER will follow up the ammonia model in the OS.95 series with compressors for other refrigerants. Compression ratio is defined as the absolute discharge pressure divided by the absolute suction pressure. A key aspect is reliable cooling capacity, which until just about two years ago was provided by an outdated refrigeration system at the EG-Schlachthof Bochum, Germany. Swept Volume from 136 cubic meters per hour to 1700 cubic meter per hour at 1000 rpm. Each percent of water in ammonia causes a 1% loss in compressor capacity (Source: IIAR Bulletin 108). This means that it is always necessary to control the compressor capacity … Open-type compressors, tend to be more effective than the hermetic and semi-hermetic type, because the suction couple in hermetic compressor enters the engine cooling, resulting in super heating of vapor and thus requiring more energy to compress. They are available with a wide variety of options and accessories to meet the growing demand for highly efficient natural refrigerant solutions. If the pressure of 14 psi (97 kPa) is reached during the time delay, the time delay relay de-energizes and the compressor continues to operate normally. h = h lc - h ec (7) where . Installation Mounting! ‘The three screw compressors can provide that with ease at just 2,900 rpm, offering a combined 1,200 kW. In addition, suction pressure entering the compressor will change the density of the suction gasses within the compressor and affect its capacity. CAUTION: Equipment damage hazard. For a constant condensing pressure, this means increased power consumption (higher electric bill) and a higher compressor exit ‘We’ve been working together since 2016. FWIW, you may compare results with the following ballpark data I took from old notes for an oil-flooded twin-rotor screw compressor on anhydrous ammonia working on a properly-maintained system. With its extensive product range, BITZER offers just the right solution for any application, The refrigeration of foods was, and still is today, a innovation regarding the use of natural refrigerants. ‘Ammonia systems are traditionally built as one-offs, often in less-than-ideal conditions. With the evaporator and condenser conditions indicated by you and no economizer, the motor would be consuming about 3.5 HP/TR, and the ammonia flow rate to the evaporator would be about 12 … Additional Information: Item Code: MSVA-306 •Pharmacuticals •Chemical •Chillers etc. Ammonia is a natural refrigerant that has been used for many years in a variety of applications due to its high thermal efficiency. Single stage ammonia industrial refrigeration system. In addition to their reliability and energy efficiency, the BITZER cooling units boast exceptionally low life cycle costs. ‘In April 2018, the total power consumption of the system was 67,988.0 kWh for the three BITZER screw compressors, putting the system’s COP/EER at 4.28 at the machine shaft – a figure that can actually be measured,’ Kruse adds. For more than 40 years, the refrigeration and air conditioning specialist has been offering solutions for ammonia applications. Two ACPs with a combined cooling capacity of 1.4 MW have maintained the right temperature at a pizza factory in northern England since early 2019. BITZER India has recently commissioned the first ammonia compressor packs in the country: in the subtropical temperatures of Khurja, a city located 80 kilometres south-east of New Delhi in northern India, the food manufacturer Creamy Foods could not exist without absolute reliability, which is why it has opted for two ammonia compressor packs in BITZER quality. The seal leak was very minor as it only occurred for a short time when the compressor started up and that there was no evidence of oil bypassing the seal was evident. As can be seen HFO1234ze(E) requires a 33% (.601/.450) larger volumetric flow rate. Choose from high-quality and efficient ammonia compressor at Alibaba.com at varied prices. It shows an interesting way to overcome the limitations in the two most critical plant units: Reforming capacity is increased by a newly added autothermal reformer, while capacity is added to the ammonia synthesis by the Uhde Dual Pressure Process. Anhydrous ammonia is the liquid form of pure ammonia gas, technically water-free, and the substance used universally as an industrial refrigerant. For example, Terminal 5 at Heathrow Airport, the largest in Europe, is cooled with ammonia.’ Thanks to their exceptional thermodynamic characteristics, R717 water coolers like this achieve much higher cooling capacities than HFC systems of a similar construction size. Ammonia Skid Packages, complete engineering from start to finish. Integrated systems controller Cooltech Unicool I for compressor units and chillers. GEA RedAstrum is the standard ammonia screw compressor heat pump for an increasing demand of efficient heating solutions. If an ammonia refrigeration system is placed outdoors, for instance as a container solution, it’s a safe alternative to synthetic refrigerants, for example in the form of a liquid chiller. The capacity of the lead compressor is controlled by an internal variable speed control, which significantly improves part load efficiency and enables a soft start. The carefully developed mechanical design also makes the compact screw compressor unit exceptionally service-friendly, as the components are easy to reach. The capacity of a compressor can be affected by a refrigeration system’s ever-changing pressures. the compressor. Tel +49 (0) 70 31 932-4327 Suitable for various refrigerants like Ammonia R-717, R-22, R-134a and other ozone friendly refrigerants. Lincoln electric motor, 200 HP, 3565 rpm, 460 V, 214 amps, 60 Hz, 3 phase. Infinite slider control with position indicator optimizes compressor capacity adjustment in line with system requirements. But more importantly, we can also operate the compressors at up to 4,200 rpm and thus achieve a maximum capacity of 1,548 kW. Limitations • Low energy efficiency: this compressor type suffers from higher losses as a Water and ammonia will co-exist and act as a kind of zeotropic refrigerant, whose saturated P-T relationship is no longer the same as anhydrous ammonia. These ammonia compressor are equipped with modernized technologies to convert air pressure into potential energy and are largely used for industrial processes.
