Fan & Pump Special VFD
V&T fan & pump VFD supports synchronous, asynchronous, magnetic‑levitation and air‑bearing motors. Built‑with flying‑start, intelligent sleep‑wake‑up and Modbus‑RTU communication, the drive delivers steady pressure regulation, fast responsiveness and 20%‑50% energy savings. It fits fans, water‑supply pumps, HVAC‑refrigeration gear, air compressors, maglev centrifugal blowers, turbo‑blowers and centrifuges.
Water Supply Inverter
E5-PA series is a new constant pressure water supply inverter launched by V&T. E5-PA inverter, combined with the multi-pump control expansion card, can realize the multi-pump constant pressure water supply in turn with circulating; Built-in PID control--the current water pressure is detected by the pressure sensor, and according to the change of water pressure, 4 pumps are automatically switched to water supply at constant pressure under same power; At the same time, it can realize overpressure alarm, underpressure alarm, multi-time water supply at constant pressure, water supply at pressure constant with designated pressure and designated date, sleep control, change pump on time etc.
V9-R AC Inverter Compressor Controller
V9-R is a special-purposed drive control unit for Compressor Controller with V/F vector control functions. It devotes to controlling water-source heat pump, air-source heat pump systems and air conditioning control system. It not only achieves requirements of cost saving, improvement on product quality and production efficiency,but also easy maintenance and easy commissioning.
