Delta VFD Industry Applications

From underground mines to high-rise HVAC systems — our variable frequency drives are engineered with application-specific firmware profiles, enclosure ratings, and communication stacks for every major industrial sector.

HVAC building automation drives

HVAC & Building Automation

Purpose-built drive firmware for air handling units, chiller compressors, cooling tower fans, and circulation pumps. Integrated BACnet MS/TP and BACnet/IP communication eliminates the need for external protocol gateways. Fire mode override, sleep function, and PID auto-tune reduce both energy consumption and commissioning time by up to 60%.

  • Built-in PID with auto-tune
  • BACnet MS/TP + IP native
  • Fire mode override (UL 2043)
  • Sleep function for energy savings
Water treatment VFD applications

Water & Wastewater

Multi-pump sequencing with automatic lead-lag rotation, sensorless flow estimation that eliminates external flow meters, and dry-run protection that safeguards pump bearings. SCADA integration via Modbus TCP provides real-time flow, pressure, and energy data across distributed pump stations.

  • Multi-pump sequencing (up to 8 pumps)
  • Sensorless flow estimation
  • Dry-run & pipe-burst protection
  • Modbus TCP SCADA integration
Oil and gas VFD solutions

Oil & Gas

ATEX Zone 1/2 and IECEx certified drives for hazardous area installations. SIL 2/3 rated Safe Torque Off (STO) function per IEC 61508, redundant PROFINET communication channels, and conformal-coated PCBs for corrosive atmospheres. Designed for artificial lift systems, gas compressors, and pipeline booster stations.

  • ATEX / IECEx Zone 1 & 2
  • SIL 2/3 Safe Torque Off
  • Conformal-coated PCBs
  • Redundant communication
Mining industry VFD applications

Mining & Minerals Processing

Heavy-duty drives rated for 150% overload for 60 seconds — built for crushers, ball mills, conveyors, and hoists. Active front-end rectifiers with regenerative braking return energy to the grid during downhill conveyor operation. IP55/IP66 enclosures withstand dust, vibration, and temperature extremes from -25°C to +55°C.

  • 150% overload for 60s
  • Regenerative braking to grid
  • -25°C to +55°C operation
  • IP55 / IP66 enclosures
Food and beverage VFD applications

Food & Beverage

Washdown-rated IP66 stainless steel enclosures for direct hose-down cleaning environments. Integrated functional safety (STO, SS1, SLS per IEC 61800-5-2) protects personnel during product changeovers. Precise speed control within ±0.01% ensures consistent filling volumes and packaging line synchronization.

  • IP66 stainless steel enclosure
  • STO, SS1, SLS safety functions
  • ±0.01% speed accuracy
  • EtherNet/IP for line sync
Advanced manufacturing VFD applications

Advanced Manufacturing

High-dynamic servo drives with sub-millisecond torque response for CNC spindles, robotic positioning, and precision winding. EtherCAT and PROFINET IRT communication enables synchronized multi-axis motion control at cycle times below 250µs. Integrated motion controller reduces cabinet footprint and wiring complexity.

  • Sub-ms torque response
  • EtherCAT / PROFINET IRT
  • <250µs cycle time
  • Integrated motion controller
