HVAC Drives & Controllers
Fans and pumps rarely need to run flat out, and letting them do so wastes energy every hour the plant operates. Variable speed HVAC drives match motor speed to the actual load, and because fan power falls with the cube of speed, a modest speed reduction cuts consumption sharply. This category pairs those drives and controllers with the equipment they run: centrifugal and extraction fans, condensing units, refrigerated air dryers and portable air conditioning. Machinery Masters lists this equipment from verified sellers, from single Danfoss VLT drives to complete fan sets, with direct seller contact and financing on qualifying listings.

HVAC Drives and Controllers Product Types
Listings here split between the drives that control air handling motors and the fan, cooling and drying plant they typically serve.
Variable speed HVAC drives
Inverter drives such as the Danfoss VLT FC100 and FC102 series, purpose-built for fan and pump duty with built-in PID control. Match the drive's kW rating and supply voltage to the motor plate, and check the IP rating for the installation environment.
Centrifugal and extraction fans
Direct and belt driven centrifugal fans from builders including Comefri, Sodeca, Ziehl Abegg and Woods, in duties from local extraction to main air handling. Impeller diameter and motor rating set the airflow and pressure the fan can deliver.
Condensing units
External refrigeration condensing units, including Daikin VRV and Zanotti monoblock types, that reject heat from air conditioning and cold room systems. Refrigerant type and cooling duty in kW are the figures that decide a match.
Refrigerated air dryers
Dryers such as the Ingersoll Rand D-series that chill compressed air to condense moisture before it reaches tools and valves. Rated by flow at pressure, with dryness expressed as a pressure dew point class under ISO 8573-1.
Portable air conditioning units
Self-contained movable units, including Broughton industrial models, that cool server rooms, control cabinets and work areas without fixed installation. Exhaust ducting to outside is the one installation requirement.
Air purifiers
Recirculating industrial air cleaners, such as AAF units, that draw workshop air through filtration and return it, reducing general dust levels between extraction points.
Brands on Machinery Masters
Drive manufacturers, European fan builders and refrigeration specialists all appear in this category. Brands shown here hold live HVAC Drives and Controllers listings on Machinery Masters, so the strip reflects genuine availability.

Por qué elegir Machinery Masters
Solo vendedores verificados
Cada vendedor se verifica antes de que se publique un solo anuncio. Machinery Masters también revisa la exactitud de los anuncios, para que los compradores puedan invertir con confianza en maquinaria de alto valor.
Alcance global
Los anuncios proceden de vendedores de toda Europa, Norteamérica y otros lugares. Ese alcance amplía las opciones más allá de cualquier red regional de distribuidores y, a menudo, es la única forma de encontrar modelos descatalogados en buen estado.
Opciones de financiación flexibles
Los anuncios que cumplen los requisitos ofrecen financiación a través de proveedores asociados. Las condiciones se muestran directamente en las páginas de producto correspondientes, repartiendo el coste en lugar de agotar el capital circulante de una sola vez.
Contacto directo con el vendedor
No hay ningún intermediario entre el comprador y el vendedor. Pregunte por el historial de mantenimiento, organice inspecciones y negocie directamente con la persona que realmente conoce la máquina.
Applications and Uses
This equipment serves any site that moves or conditions air at scale. Four settings account for most of the demand.
Plant room motor control
HVAC drives retrofit onto existing fan and pump motors to cut energy use and soften starts. A drive controlling a fan to demand typically repays its price in consumption savings alone.
Process and fume extraction
Centrifugal fans drive ducted extraction from production areas, spray zones and machine enclosures. The fan's pressure capability must cover the resistance of the full duct run and filter.
Cold rooms and conditioned spaces
Condensing units paired with evaporators hold storage areas and production rooms at temperature. Replacing a failed unit like for like avoids re-engineering the whole refrigeration circuit.
Compressed air quality
Refrigerated dryers downstream of the compressor protect pneumatic tools, actuators and paint finishes from water carried in the air line.
Benefits from Machinery Masters
Drives and air handling plant are bought under time pressure more often than not, and the marketplace serves that reality.
01
Drives and driven plant in one place
Inverter drives sit alongside the fans, condensing units and dryers they control, so a breakdown replacement or a controls upgrade starts from a single search across live stock.
02
Ratings you can compare directly
Motor kW, airflow, refrigerant type and dew point class are the figures that decide fit, and listings put them side by side across sellers rather than one dealer's shelf.
03
History from the seller, not a brochure
You ask the seller directly what duty a fan or drive ran, for how long, and why it was removed, before committing to purchase.
Frequently Asked Questions sobre HVAC Drives & Controllers
Match the drive's rated kW and output current to the motor plate, never below it, and confirm the supply voltage: most industrial units are three phase 400 V. Fan and pump duty drives such as the Danfoss VLT HVAC series suit variable torque loads. Photograph your motor plate and send it to the seller with your enquiry.
Spin the impeller by hand and feel for bearing roughness, check the blades for dust build-up, erosion and cracked welds, and look at the mounting feet for fatigue. Confirm the motor plate matches your supply and ask what the fan previously extracted, since abrasive or corrosive duties shorten impeller life considerably.
Normally no: F-Gas rules require a certificated engineer to recover the charge before the unit is moved, and another to pressure test and recharge it on installation. Confirm the refrigerant type on the data plate, because units on phased-down gases cost more to service. Budget for certificated installation when comparing against new.
Match the dryer's rated flow at your working pressure to the compressor's output with headroom, since an undersized dryer passes wet air at peak demand. Refrigerated dryers deliver a pressure dew point of around +3 °C, which covers general workshop duty; desiccant dryers are needed only for lower ISO 8573-1 classes. Ask the seller for the rated flow figure.
Drives, portable air conditioners and smaller fans travel by pallet courier, often within days, which matters when a breakdown is holding production. Larger fans and condensing units need forklift loading and flatbed transport arranged with the seller. Confirm lead time and loading responsibilities in your first enquiry through the listing.
