What Special Technical Services does

Special Technical Services (STS) is a privately held US manufacturer of static ground monitoring systems for industrial hazardous-location applications, headquartered in Budd Lake, New Jersey with a secondary accounts office in Flanders, NJ. The company's flagship product, the STS 300 Series Electronic Indicator Ground Assembly, is an electromechanical safety interlock that continuously verifies the integrity of the entire ground path — from equipment clamp through cabling to grounding rod — and automatically halts connected equipment within one second if resistance exceeds 10 ohms or continuity is broken, in compliance with NFPA 77 and API RP 2003. The system is housed in a cast-aluminum, powder-coated NEMA 7/8/9 explosion-proof enclosure rated for Class I Division 1 Group D and Class II Division 1 Group E/F/G environments, and exposes two 15A @ 120VAC dry contacts that wire directly into PLCs, SCADA systems, pumps, valves, and terminal controls for permissively interlocked shutdown.

The product line extends the STS 300 controller with a modular catalog of grounding clamps (K78160A aluminum, K78160ASRS with strain release, CB-250IP bronze, REB-IP, VUD-IP, G40 bronze, and the StaticMag neodymium magnetic clamp), straight and self-retracting coil cables in lengths up to 100 feet, standard- and heavy-duty retractable cable reels, optional deadman operator-presence controls, and a multipoint configuration that monitors multiple ground connections from a single unit. The company also sells replacement parts — circuit boards, lamp assemblies, lens caps, bulbs, phenolic insulators, and clamp repair kits — through a direct webstore at $21-$120 per item.

STS sells primarily via direct sales through its own website, combining a Request-a-Quote channel for configured ground monitoring systems with a self-serve webstore for parts and accessories. The stated customer base spans ten verticals — petroleum refining, chemical processing, rail car fill stations, vacuum and tank trucks, aviation fueling, marine terminals, oil rigs and drilling, grain and powder processing, paper manufacturing, and food and beverage — with claimed global reach across multiple continents. The company has operated for over 40 years, holds ISO 9001:2015 certification for its Budd Lake manufacturing operation, and is independently owned with no disclosed external investment.
