INVT GD290 VFD for UV New Material Production in Chemical Industry

Background

As the chemical industry strides towards high-end and green development, ultraviolet (UV) curing technology, with its outstanding advantages of high efficiency and environmental friendliness, has become a key force driving progress in numerous fields such as automotive manufacturing, 3C electronics, and OLEDs. A materials enterprise in Anhui, keeping pace with industry trends, launched an annual 60,000-ton UV new materials project. Upon full operation, the annual sales revenue is expected to exceed 1.1 billion yuan, establishing it as a significant benchmark for UV new material production in the East China region.

01 Rigorous Drive Selection

Strengthening the Foundation of Chemical Production

The mass production of high-end UV materials places extremely high demands on the precise control of the entire chemical production process. From material conversion in reaction kettles to stable transport by pumps and valves, and product purification in separation equipment, every step relies on the support of reliable drive equipment. After strict screening, the Anhui materials enterprise ultimately selected the INVT GD290 series low-voltage multi-function universal VFD. Its power range covers 4kW to 185kW, making it fully compatible with core reaction and auxiliary conveying equipment. Through deep integration with the DCS system's 4-20mA current signals, it establishes an efficient, stable, and energy-saving production drive system.

02 Addressing Key Challenges

Defining Five Core Objectives

The precise production of UV new materials, coupled with the chemical industry's requirements of "safety first, continuous production," poses stringent challenges for the VFD——

1. Stable Operation

UV material reactions are long-cycle and high-cost, requiring the VFD to operate 24/7 without failure, eliminating unplanned downtime.

2. Energy Saving & Consumption Reduction

Reaction kettles, fans, and pumps account for over 60% of energy consumption. The VFD must provide precise speed control to reduce wasted energy consumption and contribute to energy saving and emission reduction.

3. Environmental Tolerance

High temperatures and corrosive gases in the workshop can accelerate equipment aging. The VFD needs high protection and anti-interference capabilities to ensure long-term reliable operation.

4. Easy Operation & Maintenance

With VFDs covering various types of equipment and limited O&M team resources, there is a need to simplify debugging and support one-click diagnostics.

5. System Compatibility

Seamless integration with the DCS central control system is required to achieve integrated control and avoid operational lag.

Multi-dimensional Breakthroughs

From Production Capacity Assurance to Industry Leadership

• Strong Production Capacity Assurance:
  Stable driving enables continuous operation rates of over 98% for core equipment, helping achieve the annual production target of 60,000 tons and safeguarding the 1.1 billion yuan revenue goal.

• Significant Energy Consumption Reduction:
  Relying on energy-saving algorithms, average equipment energy consumption is reduced by 20%-40%, saving over one million yuan in electricity costs annually.

• Reduced Maintenance Burden:
  The "One-key Parameter Copy" function reduces the debugging time for a single device to under half an hour, cutting the debugging cycle by nearly two-thirds, and enabling faster fault localization.

From breaking through "bottleneck" materials to promoting the upgrade of chemical production, the INVT GD290, with its customized solutions and highly reliable products, demonstrates that the drive system is key to production capacity assurance and cost control. In the future, INVT will continue to deepen its efforts, launching solutions that better meet customer needs, and assisting chemical enterprises on their new journey towards "Intelligent Manufacturing + Green Development."
