Ridder Hortimax Greenhouse Climate and Irrigation Control

Ridder is a Dutch greenhouse technology group that has been developing greenhouse innovations since 1953. It serves glass and poly greenhouses as well as livestock and crop storage, with drive systems, climate screens, water treatment, labour management, robotics and process automation, and says it works in more than 100 countries with 350+ employees.

Its process automation line centres on Hortimax climate computers that integrate climate, irrigation and energy control in one system. Hortimax Go offers simple, affordable climate and irrigation control for greenhouses of any size, Hortimax Plus is a modular platform that grows with the operation, and Hortimax Pro is the professional system with an app for alerts and remote adjustments. Sensors provide real-time greenhouse data, and an open-connectivity approach links third-party tools such as Blue Radix, Aranet, Quantified and Gremon Trutina.

• Hortimax Go: simple, efficient climate and irrigation control for greenhouses of any size.
• Hortimax Plus: flexible, modular process automation launched at GreenTech 2026.
• Hortimax Pro: professional climate computer integrating all greenhouse systems with an app.
• Greenhouse sensors: real-time climate data that triggers automatic responses.
• Water treatment: irrigation water treatment line from the HortiMaX portfolio.
• Open integrations: links with Blue Radix, Aranet, Quantified and Gremon Trutina.

• High-tech greenhouse projects in Lam Dong and northern Vietnam automating climate and fertigation with Hortimax Go.
• Large tomato, cucumber and melon producers integrating climate computers with AI steering tools.
• Greenhouse builders and integrators in Vietnam bundling a European control system into turnkey projects.

• One controller for climate, irrigation and energy reduces the number of separate systems to manage.
• Scalable range from the entry-level Hortimax Go to Hortimax Pro lets growers start small and upgrade.
• Remote alerts and setting changes via app reduce the need for staff on site.
• Open connectivity allows AI steering and crop sensors from partners to be added.

Greenhouse horticulture is expanding across Asia, including China and Southeast Asia, as growers seek stable yields under hotter, more variable weather. Rising energy costs and a shortage of experienced growers push farms toward integrated climate computers and data connectivity, a need shared by Vietnam's high-tech greenhouse projects.

Founded in 1953 by Frans Nugteren. HortiMaX joined Ridder in 2011, adding water treatment, climate computers and labour management. The group reports 350+ employees, operations in 100+ countries and 1,000+ growers using its products, with over one million window-opening systems installed worldwide. In 2026 it opened a service centre in Yunnan, China.
