What Haket does

Haket Handelsonderneming B.V. is a privately held, family-owned Dutch engineering and installation company founded in January 1979 by Dolf Haket, headquartered in Wateringen, Netherlands, with approximately 20 employees. The company designs, builds, and services custom water-technical and screen-technical installations for modern greenhouse horticulture, operating across two core product lines: Water Technology (pump units, water storage basins from 550–20,000 m3, high-pressure humidification at 105 bar, drip and ebb-and-flow irrigation, drain water disinfection via NoVira LD-UV, reverse osmosis, iron removal, fertilizer dosing, and silo inspection) and Screen Technology (energy screens, facade screens, blackout systems, and insect netting). It also integrates climate computers from Hoogendoorn, ISII, and Sercom as part of turnkey greenhouse projects.

Haket's business model is project-based and enterprise-focused: the majority of revenue is generated through one-time installation contracts for custom water and screen systems, supplemented by recurring maintenance, 24/7 emergency repair, and certified silo inspection services required by insurers. The company sells directly to greenhouse operators across at least seven countries — the Netherlands, Belgium, Croatia, Poland, Greece, Canada, and Kazakhstan — with international projects executed from its Dutch headquarters, occasionally in partnership with local channel partners such as Zwart Systems. Customer segments span greenhouse horticulture (flowers, vegetables, fruits, seeds, research), with smaller forays into adjacent applications such as poultry barns and urban green infrastructure.

The company is differentiated by 45+ years of specialized engineering experience, VCA and HortiQ certifications, and memberships in AVAG (the Dutch greenhouse technology cluster of 70+ firms) and Club van 100 at Wageningen UR Glastuinbouw. Haket previously combined operations with Elektravon under the Elektravon-Haket brand to offer fully integrated installations including electrical engineering, grow lighting, security, data, and telephony, before rebranding back to Haket in 2019 with a strategic refocus on its core water and screen technical specialization.

Broad incumbents

• Dalsem: Dutch greenhouse construction and technical systems provider serving international horticulture. Comparable on combined greenhouse build and technical installation projects, including water and screen systems for commercial growers.
• Royal Brinkman: Largest Dutch supplier to greenhouse horticulture, offering a broad portfolio of crop protection, technical equipment, and services. Comparable to Haket as a Dutch-based full-spectrum partner for greenhouse operators; broader scale and wider product breadth than Haket's water-and-screen specialization.
• Certhon: Dutch turnkey greenhouse builder and technical systems installer with international reach. Comparable on full-scope greenhouse project execution including water and screen installations; broader scope including structure construction that Haket does not perform.
• Van der Hoeven Horticultural Projects: Dutch high-tech greenhouse builder and technology integrator with global project execution. Comparable on turnkey delivery of greenhouse water, climate, and screen installations to international growers; larger scale than Haket.

Direct peers

• Hoogendoorn Growth Management: Dutch climate computer and process automation supplier whose systems Haket integrates into its installations. Comparable as a Dutch horticultural technology specialist selling integrated control solutions; Haket is a customer/integrator of Hoogendoorn products in its projects.
• Priva: Dutch climate and process control provider for horticulture and indoor growing. Comparable technology layer (climate computers, sensors, automation) and overlap on integrated water and climate management for greenhouses; competes for the same Dutch and international project specifications.
• Svensson: Swedish/Dutch manufacturer of climate screens and energy-saving textiles for greenhouses. Holds HortiQ certification alongside Haket; directly comparable on screen/energy-screen product line for greenhouse climate control.
• Ridder Drive Systems: Dutch provider of screen installations, drive systems, and climate control solutions for greenhouses. Directly comparable to Haket's screening-technology line and overlaps on water/irrigation integration; serves the same Dutch horticultural customer base with similar turnkey projects.

Emerging players

• Kubo Green Projects: Dutch high-tech greenhouse builder specializing in innovative projects. Comparable in delivering complete greenhouse projects internationally; overlaps on technical installation scope but is more focused on full turnkey builds.

Regional players

• Zwart Systems: Canadian greenhouse technology supplier collaborating with Haket on the Orangeline Farms project in Canada. Comparable as a greenhouse technical installer, but primarily North America-focused rather than Netherlands-based like Haket.
