Fans need predictable starts and clean EMC. Soft starters cap inrush to 3–4× In; VFDs with C2/C3 filters and input chokes tame harmonics. Typical ranges cover 0.37–15 kW at 230/400 V AC, IP54/55 motors, and fire-mode bypass where required. Terminals accept 0.5…4 mm² Cu with 0.6–1.2 Nm torque; analogue inputs 0–10 V/4–20 mA drive PI for static-pressure hold. Crews standardise thorgeon ventilator control so the same ramps, filter classes, and shield clamps repeat across plant rooms.
Closed-loop sets use dual PID (pressure and level), sleep/wake to stop heat in low demand, and dry-run detection from power factor change. Cavitation guards watch noise bands; soft-fill avoids water hammer. For booster frames, 2–4 pumps rotate by hours; VFD duty usually sits at 30–60 Hz with check-valve interlocks. Maintenance teams label spares against thorgeon pump control skids by kW, pipe size, and sensor type so swaps don’t disturb tuning.
Profiles handle ramp-up, creep-to-endstop, and anti-crush via monitored edges and photocells per EN 12453/12445. Encoder inputs (A/B/Z) keep travel consistent; thermal trips and stall timers protect gearboxes. Typical drives are 230 V single-phase to 1.1 kW or 3-phase for industrial shutters. Installers catalogue thorgeon gate operator control by torque class, leaf mass, and I/O so the same harness and safety chain apply site-wide.
AHU scripts link supply/return fans, dampers, and heater valves with frost protection and filter DP alarms. BACnet/Modbus expose setpoints; DOs interlock smoke control and fire alarm links. Keep 7.5–10 mm breathing around warm drives; publish EMC practice—360° braid clamps at gland plates, SELV/mains segregation—to repeat results with thorgeon hvac automation on every floor.
Roof fans, scrubbers, and car-park jet units demand higher surge immunity (≥ 4 kV), IP65 field boxes, and stainless fixings. Filter stages add current draw; derate curves consider Δp rise. Where VFD cable lengths exceed 30–50 m, dV/dt filters protect motor insulation. Spec sheets for thorgeon industrial ventilation systems list cable types, screen termination, and max lead lengths so acceptance tests are unambiguous.
Pressure transducers 0–10 bar, ultrasonic or hydrostatic level sensors, relay manifolds, and fused isolators share one footprint and marker scheme. Bypass contactors meet IEC 60947-4-1; MCB/RCBO curves coordinate upstream. Panel doors carry clear P&IDs with tap-off points. Stocking thorgeon control accessories for pumps by thread, range, and signal type keeps night-shift swap-outs tidy.
I/O blocks take monitored edges, safety relays, keypad/reader inputs, and wireless fobs; time channels manage auto-close and holiday logic. Torque learn stores per-gate friction; service counters warn at cycle thresholds. For exposed runs, specify screened cable and surge on all field lines. Commissioning sheets for thorgeon automation for gates record force test results, encoder direction, and stop-to-stop time.
Fix motor kW and duty first, then choose VFD vs soft-starter and filter class. Define sensors (range, output type), safety chain, and comms. Confirm enclosure IP/IK and ambient; publish torque windows, strip lengths, and shield strategy. Room-bundle cabinets and field kits by riser so spares and drawings stay aligned.
Procurement follows your commissioning windows. You get project-specific pricing, near-hour quote turnaround with EAN/MPN, and live EU stock before crews are booked. The portal shows lead times, shipment tracking, and downloadable price lists with validity periods you can plan against. Trusted clients can use post-payment up to 30 days. We consolidate partials so panels, drives, sensors, safety relays, and field boxes arrive room-bundled, and your account manager cross-checks kW ranges, curve/coordination tables, enclosure IP, shield termination, torque notes, and labelling against your drawings—keeping deliveries site-ready across France, the Baltics, Germany, Spain, Italy, Belgium, and the Netherlands.
