What South-Tek does

South-Tek Systems LLC is a privately held Wilmington, North Carolina-based manufacturer of on-premise nitrogen generation systems and industrial compressed air equipment, founded circa 2003. The company's core technology stack centers on dual-bed Pressure Swing Adsorption (PSA) using Carbon Molecular Sieve plus membrane filtration, delivering nitrogen purity from 98% up to 99.9995% and flow rates from 1 to 75,000 SCFH across the N2GEN product family, complemented by rotary screw air compressors (STSP, STSD, STS series) and a full accessory line of dryers, filters, and the Smart-Trak remote monitoring interface.

The commercial product portfolio is organized around vertical-specific sub-brands: N2Blast and DeOx for fire-protection sprinkler corrosion inhibition, N2GEN Industrial Series for metals and electronics, N2GEN TL for broadcast transmission line pressurization, N2GEN S for pharmaceutical/medical, HPCF-K0 and HPCD-01D for U.S. military deployment, and BeerBlast/BrewBlast for beverage dispense. Patented proprietary technology includes the AutoPurge System with calibrated orifice for fire-protection risers. The company serves at least ten verticals including fire protection, industrial metals, food & beverage, military, electronics, pharmaceutical, oil & gas, power, renewable energy, and broadcast/transmission.

South-Tek monetizes primarily through capital-equipment sales (quote-based purchase, plus rental and lease options) with a 12-14 month average customer ROI and 18-24 year system life that drives a recurring parts, filter, and service revenue tail. Go-to-market combines enterprise field sales, a registered distributor and service-partner channel, inside sales, and event-driven activity including CEU training for specifiers and trade shows such as Braubeviale. The company maintains no disclosed outside investors and is led by President & CEO Jens Bolleyer, appointed December 2021.
