Variable speed screw compressor 15 kW

Variable speed screw compressor 15 kW. A variable speed screw compressor adjusts its output to demand instead of running loaded and unloaded. On variable demand it typically uses 20–35% less energy than a fixed-speed compressor.

Key features

• Power: 15 kW
• Pressure: 7.5–13 bar
• Control: VSD, Modbus

Why compressed air matters

• Compressed air is one of the most expensive utilities in a plant: most of the electricity becomes heat.
• Leaks of 20–30% of output are common. Each 1 bar of unnecessary pressure costs about 7% more compressor energy.

Connecting to Plantmargin

Compressor controllers and flow meters connect over Modbus; the compressor's feeder meter gives its power. Plantmargin reads air flow, pressure and compressor power every 10 seconds through the edge gateway, stores it for years as hourly figures, draws it against its normal band, and uses it in cost per unit, alarms and verified savings. The installer pack for your plant lists the exact register or channel to use.

Before you order

• Measure first: Plantmargin (or a portable logger) shows the real demand profile, so the compressor is sized to it, not to the old one.

Warranty and support

• Manufacturer's warranty, usually 12–24 months from delivery; the exact period is stated on your quotation.
• Supplied with the datasheet and manual; calibration or test certificate where the product has one.
• Installation, commissioning and connection to Plantmargin can be quoted with the product.
