Variable Speed Drive
Variable Speed Drive (VSD) is used to change speed of motor by the input voltage. It is used for both for AC and DC motors.
Variable Frequency Drive (VFD) is used to control speed by changing voltage and frequency, they are therefore used with AC motors
Seamless Process Automation Limited offer drives as wall mount, inside a control enclosure or mounted on free standing enclosure depending on the rating. These drives offer substantial savings in power consumption by optimizing motor torque and power depending on demand. Additionally, drives provide soft start functionality to protect transmission systems from sudden torque spikes on start-up.
We cover wide range of drives offering both single phase and three phase which are stocked from 0.37kw to 90kW. Higher ratings are availed on request. In addition to standard stocked items, we have wide range of expertise in design, programming, commissioning and maintenance of control systems offering our customers a complete variable speed drive solution. We offer solutions for multi-varied applications including food & beverages, packaging, transportation, HVAC, productions lines, water & waste water.
Our popular variable speed drives used in Kenya include but not limited to…
We have warehouses in Nairobi Kenya. We provide a bespoke, personal and quality service with experienced engineers, sales and service departments. Our qualified technicians ensures the highest standards and level of expertise in design, assembly and installation of equipment.
