Screw Compressor with VFD

// Energy Optimization

Constant Pressure Variable Operating Technology

Standard fixed-speed compressors constantly cycle between load and unload presets, causing severe power spikes and idling losses. In contrast, Frank Inverter (VFD) screw compressors maintain continuous fluid operations by dynamically adjusting motor RPM to provide a constant line pressure matched exactly to production demands.

Branded Reliable Inverters

Sourced from world-renowned engineering automation partners, our variable speed packages offer genuine power drops from day one. Simplified cabinet layouts feature user-friendly access panels for convenient cleaning and checks.

Constant Line Pressure

Maintains stable grid pressure values eliminating system pressure drops completely.

Soft Start Control

Eliminates peak current startup surges, preserving internal winding lifespans.

Salient Product Features

Low RPM Air Ends: Heavy-duty profile engineered for higher continuous CFM capacity.
Intelligent Touch Panel: Digitally monitors standard conditions, torque metrics, and service alarms.
Low Carryover Separators: Reduces oil grid carryover cleanly below 3 PPM.
Rapid Capital Return: Three years of electricity savings directly offset the equipment's capital cost.

Target Sectors: Textiles, Foundries, Automotive, Packaging Grids, Mining, Dairies, Oil & Gas plants.
