The compression chambers run completely free of oil, and the package carries the ISO 8573-1 CLASS 0 (2010) certification verified by T\u00dcV.<\/p>\n<p>The integrated drive adjusts the motor speed to the air demand of the plant in real time, so the ZR 75 VSD delivers energy savings of up to 35 percent where the consumption profile fluctuates. Two pressure versions at 8.6 and 10.4 bar(e) cover free air delivery from 74 to 259 l\/s at maximum working pressure, and the water-cooled circuit opens the full heat recovery potential of the platform.<\/p>\n<h2>Where the ZR 75 VSD Sits in the Oil-Free Range<\/h2>\n<p>The ZR\/ZT 55-90 family serves the plants whose oil-free demand has outgrown the smaller packages but has not yet reached the ZR\/ZT 110-275 class. Within the family, the ZR 75 VSD shares its rating with the fixed-speed ZR 75 and the air-cooled ZT 75 VSD, and the letter Z marks the oil-free architecture: the precision-cut rotors never touch, so the compression chamber needs no lubrication and no oil can reach the air stream.<\/p>\n<p>Atlas Copco pioneered Variable Speed Drive technology in the compressed air industry and pioneered oil-free air over sixty years, becoming the first manufacturer awarded CLASS 0 certification. The ZR 75 VSD combines both lines in one package: an all-in-one installation that places on a flat floor, connects to the power line, the cooling water circuit and the air outlet, and starts with the push of a button.<\/p>\n<h3>Dos sucursales, una plataforma<\/h3>\n<p>Two names describe the branches of the ZR 75 VSD, and each adds one fact:<\/p>\n<ul>\n<li>Est\u00e1ndar: el grupo compresor suministra aire libre de aceite para redes con un sistema externo de tratamiento de aire situado aguas abajo; su dise\u00f1o refrigerado por agua disipa el calor de la compresi\u00f3n al circuito de agua de refrigeraci\u00f3n.<\/li>\n<li>FF \u2014 Funcionalidad completa: el paquete integra el secador por adsorci\u00f3n IMD, por lo que el aire seco sale directamente de la m\u00e1quina sin que se consuma energ\u00eda externa en la regeneraci\u00f3n.<\/li>\n<\/ul>\n<p>Every version combines with both branches, and the working pressure of the Full Feature variant is confirmed with Atlas Copco for the specific order. The ZR 75 VSD carries both branches on one platform, so a plant can start with the Standard build and move to the Full Feature dryer without changing the machine room layout. Plants that run a steady load instead of a swinging profile pick the fixed-speed ZR 75 of the same rating.<\/p>\n<figure id=\"attachment_8537\" class=\"wp-caption aligncenter\" style=\"width: 300px\" aria-describedby=\"caption-attachment-8537\"><img fetchpriority=\"high\" decoding=\"async\" class=\"size-medium wp-image-8537\" src=\"https:\/\/www.compressorpartsmall.com\/wp-content\/uploads\/2026\/10\/Atlas-Copco-ZR-75-VSD-1-300x225.webp\" alt=\"Atlas Copco ZR 75 VSD (1)\" width=\"300\" height=\"225\" srcset=\"https:\/\/www.compressorpartsmall.com\/wp-content\/uploads\/2026\/10\/Atlas-Copco-ZR-75-VSD-1-300x225.webp 300w, https:\/\/www.compressorpartsmall.com\/wp-content\/uploads\/2026\/10\/Atlas-Copco-ZR-75-VSD-1-768x576.webp 768w, https:\/\/www.compressorpartsmall.com\/wp-content\/uploads\/2026\/10\/Atlas-Copco-ZR-75-VSD-1-600x450.webp 600w, https:\/\/www.compressorpartsmall.com\/wp-content\/uploads\/2026\/10\/Atlas-Copco-ZR-75-VSD-1.webp 800w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><figcaption id=\"caption-attachment-8537\" class=\"wp-caption-text\">Atlas Copco ZR 75 VSD (1)<\/figcaption><\/figure>\n<h2>C\u00f3mo funciona el VSD integrado<\/h2>\n<p>Over 80 percent of the lifecycle cost of a compressor is taken up by the energy it consumes, and the generation of compressed air can account for more than 40 percent of the total electricity bill of a plant. The ZR 75 VSD attacks that share directly: the drive closely follows the air demand by automatically adjusting the motor speed, which results in energy savings of up to 35 percent.<\/p>\n<h3>\u00bfQu\u00e9 tiene de especial el dise\u00f1o integrado?<\/h3>\n<p>El dise\u00f1o integrado se diferencia de un accionamiento acoplado mediante pernos en varios aspectos, y cada uno de ellos garantiza el rendimiento del conjunto:<\/p>\n<ul>\n<li>El controlador Elektronikon gestiona tanto el compresor como el convertidor integrado, lo que garantiza la m\u00e1xima seguridad de la m\u00e1quina dentro de los par\u00e1metros establecidos.<\/li>\n<li>La selecci\u00f3n flexible de la presi\u00f3n, entre 4 y 10,4 bar(e), reduce el consumo el\u00e9ctrico ajust\u00e1ndose a la presi\u00f3n real que requiere el proceso.<\/li>\n<li>El convertidor y el motor est\u00e1n dise\u00f1ados como una sola unidad, con rodamientos protegidos para garantizar la m\u00e1xima eficiencia en todo el rango de velocidades.<\/li>\n<li>El motor el\u00e9ctrico est\u00e1 dise\u00f1ado espec\u00edficamente para velocidades de funcionamiento bajas, prestando especial atenci\u00f3n a los requisitos de refrigeraci\u00f3n tanto del motor como del compresor.<\/li>\n<li>Todos los compresores VSD han sido sometidos a pruebas de compatibilidad electromagn\u00e9tica (CEM) y cuentan con la correspondiente certificaci\u00f3n, por lo que el funcionamiento del compresor no afecta a las fuentes externas y viceversa.<\/li>\n<li>Las mejoras mec\u00e1nicas garantizan que todos los componentes funcionen por debajo de los niveles cr\u00edticos de vibraci\u00f3n en todo el rango de velocidades.<\/li>\n<li>En el interior de la carcasa hay un convertidor de frecuencia de alta eficiencia ubicado en su propio compartimento.<\/li>\n<\/ul>\n<p>Full regulation between 30 and 100 percent of the maximum capacity eliminates the unload losses of a fixed-speed machine, and no compressed air is blown off to the atmosphere. The Life Cycle Cost of the installation drops by an average of 22 percent, and a lowered system pressure band trims the energy use across the production further. For a plant whose demand never stands still, the ZR 75 VSD turns those figures into a lower electricity bill from the first month of operation.<\/p>\n<h2>Technical Specifications of the ZR 75 VSD<\/h2>\n<p>The table below condenses the ZR 75 VSD into its headline figures:<\/p>\n<table width=\"100%\">\n<tbody>\n<tr>\n<th>Par\u00e1metro<\/th>\n<th>Valor<\/th>\n<\/tr>\n<tr>\n<td>Modelo<\/td>\n<td>Atlas Copco ZR 75 VSD<\/td>\n<\/tr>\n<tr>\n<td>Tipo de compresor<\/td>\n<td>Oil-free rotary screw, water-cooled, integrated VSD<\/td>\n<\/tr>\n<tr>\n<td>Control de capacidad<\/td>\n<td>Velocidad variable, capacidad m\u00e1xima de 30-100%<\/td>\n<\/tr>\n<tr>\n<td>Potencia del motor instalado<\/td>\n<td>75 kW \/ 100 hp<\/td>\n<\/tr>\n<tr>\n<td>Versiones de presi\u00f3n<\/td>\n<td>8,6 \/ 10,4 bar(e), rango de funcionamiento de 4 a 10,4 bar(e)<\/td>\n<\/tr>\n<tr>\n<td>Entrega gratuita por v\u00eda a\u00e9rea<\/td>\n<td>74-259 l\/s at maximum working pressure by variant<\/td>\n<\/tr>\n<tr>\n<td>Compilaci\u00f3n VSD+<\/td>\n<td>10.4 bar(e) class, 77.6-242.5 l\/s, dual NEOS drives, plus a 13 bar variant<\/td>\n<\/tr>\n<tr>\n<td>Nivel sonoro<\/td>\n<td>74 dB(A) en el puesto de trabajo<\/td>\n<\/tr>\n<tr>\n<td>Pureza del aire<\/td>\n<td>ISO 8573-1 CLASE 0 (2010), certificado por T\u00dcV<\/td>\n<\/tr>\n<tr>\n<td>Frecuencia<\/td>\n<td>50 Hz y 60 Hz<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3>Datos nominales por variante de presi\u00f3n<\/h3>\n<p>El rendimiento de la unidad se mide seg\u00fan la norma ISO 1217, anexo C, edici\u00f3n 4 (2009), y, en el caso de los equipos con variador de velocidad (VSD), el caudal de aire libre se mide a la presi\u00f3n m\u00e1xima de trabajo de cada variante.

T\u00dcV type-tested the range with the most rigorous methodologies available, measuring all possible oil forms across a range of temperatures and pressures, and found no traces of oil at all in the output air stream. CLASS 0 is the most stringent class of the standard: the total oil concentration is as specified by the equipment user or supplier and more stringent than class 1.<\/p>\n<p>That certification is what makes the ZR 75 VSD the default choice where a single trace of oil spoils a batch: food and beverage lines running fermentation, packaging and filling, electronics plants cleaning chips and boards, petrochemical operations in extreme heat and humidity, and pharmaceutical production from tablet coating to bottling.<\/p>\n<h3>Refrigeraci\u00f3n por agua y recuperaci\u00f3n de calor<\/h3>\n<p>Water cooling defines the ZR branch of the family.

La regulaci\u00f3n funciona de forma continua entre el 30 % y el 100 % de la capacidad m\u00e1xima sin p\u00e9rdidas por descarga ni purga. La versi\u00f3n VSD+ de la plataforma incorpora dos variadores NEOS que regulan la m\u00e1quina entre el 28 % y el 100 % de la carga.<\/p>\n<h3>Is the ZR 75 VSD water-cooled?<\/h3>\n<p>Yes. The ZR letter marks the water-cooled branch of the ZR\/ZT family: the cooling water circuit carries the heat of compression out of the frame, which holds the sound level at 74 dB(A) and enables heat recovery. The air-cooled equivalent is the ZT 75 VSD.<\/p>\n<h3>\u00bfHasta qu\u00e9 punto est\u00e1 libre de aceite el aire?<\/h3>\n<p>The ZR 75 VSD carries the ISO 8573-1 CLASS 0 (2010) certification verified by T\u00dcV, the most stringent class of the standard. T\u00dcV testing found no traces of oil at all in the output air stream across the tested range.<\/p>\n<h3>\u00bfQu\u00e9 incluye la versi\u00f3n \u00abFull Feature\u00bb?<\/h3>\n<p>FF integrates the IMD adsorption dryer inside the compressor package. The dryer regenerates with the heat of the compressor, so no external energy is needed, and the package weight grows from 1,925 kg to 2,170 kg while the footprint stays at 2,180 \u00d7 1,450 \u00d7 2,184 mm.<\/p>\n<h3>How loud is the ZR 75 VSD?<\/h3>\n<p>The sound pressure level at the work station reads 74 dB(A) on both pressure variants. The value follows ISO 2151: 2004 with the ISO 9614\/2 method and carries a total uncertainty value of 3 dB(A).<\/p>","protected":false},"excerpt":{"rendered":"<p>The Atlas Copco ZR 75 VSD is the water-cooled oil-free rotary screw compressor with an integrated Variable Speed Drive, regulating output continuously between 30 and 100 percent of capacity across the 8.6 and 10.4 bar(e) versions, with free air delivery from 74 to 259 l\/s at maximum working pressure. The water-cooled design opens the full heat recovery potential of the platform, and the package carries the T\u00dcV-verified ISO 8573-1 CLASS 0 certification. The VSD+ build of the platform extends the 10.4 bar class to 77.6 to 242.5 l\/s and adds a 13 bar VSD+ variant.
