What Dairyland Electrical Industries does

Dairyland Electrical Industries is a privately held, family-owned manufacturer of solid-state electrical protection devices, founded in 1983 by Henry Tachick and headquartered in Stoughton, Wisconsin, with production in Pound, Wisconsin. The company originated by solving stray-voltage issues on dairy farms and evolved into what it describes as the world's leading manufacturer of solid-state decouplers for the cathodic protection industry. Its core technology enables simultaneous DC decoupling and AC continuity/grounding — protecting buried or submerged metallic infrastructure from induced AC voltage, lightning, and AC fault currents while preserving cathodic protection performance. The product portfolio is organized into solid-state decouplers (PCRX, PCR, SSD, PCRH, ISP), solid-state over-voltage protectors (OVP, OVP2), and specialty products (Overwatch HEFPD for rail, UltraBox modular junction boxes, gradient control mats, marine galvanic isolators, and farm neutral isolators).

Dairyland serves enterprise customers across at least six verticals: oil and gas pipelines, electric utilities, railroads, marine, airport fueling, and agriculture. Sales are executed through an enterprise field-sales motion with dedicated Market Segment Managers for pipelines and utilities, combined with a distributor-channel model in which quotes are configured online and routed through an Inside Sales team to trusted channel partners. Products are configured to order with custom fault-current ratings, blocking thresholds, hazardous-location certifications, and enclosure options, generating unique model numbers and quote-based pricing rather than list pricing. International reach is supported by extensive third-party certifications (UL, C-UL, CE, ATEX, IECEx, UKEx, EAC, ISO 9001:2015, AREMA, ABYC A-28), enabling deployment in regulated hazardous environments globally.

The company is currently led by Mike Tachick as President, with Kailey Tachick as EVP of Finance, Systems, & Culture and Logan Tachick as Senior Operations Manager; the broader executive team includes EVPs of Strategic Growth and Operations. Recent strategic emphasis has been on product-line expansion (Overwatch HEFPD launched 2021, Direct Bury Enclosure launched 2024), sustained certification investment, and a "Customer Service to the Extreme" cultural initiative announced in late 2025. No acquisitions, external funding rounds, or institutional investors are disclosed, and revenue is not publicly reported.

Core offering

Dairyland Electrical Industries manufactures solid-state decouplers (PCRX, PCR, SSD, PCRH, ISP), solid-state over-voltage protectors (OVP, OVP2), and specialty products (Overwatch HEFPD, UltraBox, GCM, Galvanic Isolators, Neutral Isolator). Devices provide DC decoupling while simultaneously maintaining AC continuity/grounding for cathodically protected structures across pipeline, utility, railroad, and marine applications.

Product overview

Dairyland Electrical Industries is the world's leading manufacturer of solid-state decoupling products for the corrosion protection industry, operating since 1983. The company's product portfolio consists primarily of rugged electrical hardware devices organized into three main categories: Solid-State Decouplers (PCRX, PCR, SSD, PCRH, ISP), Solid-State Over-Voltage Protectors (OVP, OVP2), and Specialty Products (Overwatch HEFPD, UltraBox, GCM, Galvanic Isolators, Neutral Isolator/VTNI). Decouplers provide DC isolation while grounding AC fault current and lightning for cathodically protected structures. Over-voltage protectors offer fault current and lightning protection without addressing induced AC. Specialty products serve niche applications including railroad fault protection, marine galvanic isolation, gradient control, and stray voltage mitigation. The company also offers a comprehensive line of accessories including mounting kits, enclosures, testing equipment, and isolation switches. Products are backed by extensive third-party certifications including UL, CE, ATEX, IECEx, UKEx, and EAC for global hazardous location deployments.

Expansion highlights6 records

Direct peers

• Apecor: Apecor manufactures solid-state DC decoupling devices for cathodic protection — the closest pure-play competitor to Dairyland's PCR/SSD/PCRX decoupler line, with overlapping use cases in CP and AC mitigation.
• DEHN SE: DEHN manufactures surge protection, lightning protection, and grounding components for industrial and rail applications, competing head-on with Dairyland's OVP and railroad Overwatch HEFPD products in adjacent but overlapping specification environments.
• CITEL: CITEL produces AC and DC surge protective devices used in PV, telecom, and industrial installations — closely comparable to Dairyland's OVP/OVP2 over-voltage protection line in application and customer profile.

Broad incumbents

• ABB: ABB's electrical products portfolio includes surge arresters, transformers, and grid protection equipment, putting it in the same specification universe as Dairyland's decoupling and over-voltage protection devices for utility and pipeline customers.
• Hubbell: Hubbell's electrical systems segment covers wiring devices and protection products for utility and industrial applications, positioning it as a broad competitor in the same end-customer base as Dairyland.
• Schneider Electric: Schneider Electric offers surge protection, power distribution, and industrial control equipment globally, competing with Dairyland for similar utility, rail, and industrial protection specifications at scale.
• nVent ERICO: nVent's ERICO product line covers grounding, surge, and cathodic protection hardware with global channel reach — directly comparable to Dairyland's pipeline, utility, and railroad protection offerings, but operating as part of a much larger diversified portfolio.
• Eaton: Eaton supplies surge protection devices, power conditioning, and industrial control components, overlapping with Dairyland's circuit-protection and over-voltage product categories across utilities and industrial end markets.

Emerging players

• Polaris (formerly known as Trenton Cathodic Protection / Trinity Castings-adjacent): Polaris is a cathodic protection specialty firm serving the pipeline and storage tank market — comparable to Dairyland at the customer level (CP engineers and pipeline operators) although it competes more on anodes/CP hardware than solid-state decoupling.

Regional players

• Cimarron Energy (Cimarron Corrosion Services): Cimarron provides cathodic protection engineering, materials, and rectifier systems across North American oil & gas, supplying the same pipeline and tank-owner customers as Dairyland but from a complementary (not direct substitution) product angle.
