EL-Piast

What EL-Piast does

EL-Piast Sp. z o.o. is a privately held Polish manufacturer of industrial automation, electronics, and control devices, founded in 2005 and headquartered in Wrocław with production operations in Oleśnica. The company designs and produces freely programmable PLC controllers (ELP10, ELP11R32L, ELP12, ELP13, ELP14 series), expansion modules, HMI operator panels, sensors and transducers for CO2, humidity, temperature, and pressure, communication gateways, speed regulators, electric heater modules, and prefabricated control and power-supply cabinets. Its underlying technology stack centers on the proprietary MacroControl block-based programming environment (offered free of charge), the ELP-Bus protocol, and the more recent V-ONE single two-wire communication-and-power system for HVAC units, supplemented by the AES 256-bit encrypted ELP-STORM controller for security-critical deployments and the ELP Cloud BMS/EMS platform.

The company sells primarily through four channels: direct regional sales specialists covering northwest, southwest, southeast, and northeast Poland; an OEM automation business embedding EL-Piast controllers into equipment from HVAC manufacturers such as VTS, Klimor, Dospel, VentiAir, ALLTS, and INWAP; a BMS/EMS integration services practice targeting commercial and public buildings, industrial facilities, and distributed building portfolios; and a direct e-commerce storefront (el-piast24h.com) for standard PLC accessories. Pricing is quote-based and not publicly disclosed. Revenue lines split between hardware product sales (PLC hardware, sensors, cabinets) and professional services (OEM automation design, BMS/EMS design-build, technical support, training).

The customer base is anchored in Polish HVAC OEMs and building integrators, with limited but diversifying exposure to government (cold-storage for the Polish Material Reserves Agency during COVID-19), educational institutions (didactic tester kits), and Nordic-adjacent building monitoring via VILPE integration. Production capacity exceeds 1,000 control cabinets per month out of a facility operational since 2011, and the company maintains CE, PZH hygiene, and ISO 50001 energy-management certifications.
