With the correct water pressure, it provides a \u003cstrong\u003ecapacity of up to 10 litres per hour\u003c\/strong\u003e and is suitable for systems with an airflow of \u003cstrong\u003e600–700 m³\u003c\/strong\u003e. It operates without fine mist in the room, humidifying the air efficiently through evaporation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHE402 is designed for professional applications where precise humidity control is required.\u003c\/strong\u003e It is installed in an air duct with a diameter of \u003cstrong\u003eØ200 mm\u003c\/strong\u003e and operates together with a suitable inline fan. For maximum performance, the manufacturer recommends inlet water pressure of \u003cstrong\u003eat least 2 bar\u003c\/strong\u003e and an incoming air temperature of around \u003cstrong\u003e28–30°C\u003c\/strong\u003e. Under these conditions, the system achieves optimal humidification capacity.\u003c\/p\u003e\r\n\r\n\u003cp\u003eThe humidifier uses a special \u003cstrong\u003eevaporative element\u003c\/strong\u003e through which the airflow passes. This allows even humidification without forming free water mist in the room, which is particularly suitable for environments with lighting, electronics and sensitive equipment.\u003c\/p\u003e\r\n\r\n\u003cp\u003eIf higher capacity is required, the system can be combined with a \u003cstrong\u003ebooster pump\u003c\/strong\u003e, which raises water pressure to \u003cstrong\u003e8 bar\u003c\/strong\u003e. This atomises the water into significantly finer droplets, improving evaporation and increasing humidification efficiency.\u003c\/p\u003e\r\n\r\n\u003cp\u003eFor automatic operation, the manufacturer recommends using a \u003cstrong\u003ehumidistat\u003c\/strong\u003e, which simultaneously controls the solenoid water valve, the fan and any booster pump. This way, the humidifier operates only when needed and a stable relative-humidity level is maintained.\u003c\/p\u003e\r\n\r\n\u003cp\u003eInstalling an \u003cstrong\u003eair-distribution sleeve\u003c\/strong\u003e after the humidifier helps distribute humid air more evenly in the room, while using a filter before the fan limits dust accumulation on the evaporative element. An additional benefit of the system is that it also has a \u003cstrong\u003eslight cooling effect\u003c\/strong\u003e on the air during operation.\u003c\/p\u003e\r\n\r\n\u003cp\u003e \u003c\/p\u003e\r\n\r\n\u003ch2\u003e\u003cstrong\u003eTechnical specifications\u003c\/strong\u003e\u003c\/h2\u003e\r\n\r\n\u003cp\u003e✔️ \u003cstrong\u003eType:\u003c\/strong\u003e Duct air humidifier\u003c\/p\u003e\r\n\r\n\u003cp\u003e✔️ \u003cstrong\u003eModel:\u003c\/strong\u003e HE402\u003c\/p\u003e\r\n\r\n\u003cp\u003e✔️ \u003cstrong\u003eInstallation diameter:\u003c\/strong\u003e Ø200 mm\u003c\/p\u003e\r\n\r\n\u003cp\u003e✔️ \u003cstrong\u003eHumidification capacity:\u003c\/strong\u003e up to \u003cstrong\u003e10 L\/hour\u003c\/strong\u003e\u003c\/p\u003e\r\n\r\n\u003cp\u003e✔️ \u003cstrong\u003eRecommended airflow:\u003c\/strong\u003e \u003cstrong\u003e600–700 m³\u003c\/strong\u003e\u003c\/p\u003e\r\n\r\n\u003cp\u003e✔️ \u003cstrong\u003eMinimum water pressure:\u003c\/strong\u003e 2 bar\u003c\/p\u003e\r\n\r\n\u003cp\u003e✔️ \u003cstrong\u003eOptimal incoming air temperature:\u003c\/strong\u003e 28–30°C\u003c\/p\u003e\r\n\r\n\u003cp\u003e✔️ \u003cstrong\u003eCan be used with a booster pump (up to 8 bar)\u003c\/strong\u003e\u003c\/p\u003e\r\n\r\n\u003cp\u003e✔️ \u003cstrong\u003eCompatible with Ruck RKS 200L inline fan\u003c\/strong\u003e\u003c\/p\u003e\r\n\r\n\u003cp\u003e✔️ \u003cstrong\u003eSuitable for automatic control via a humidistat\u003c\/strong\u003e.\u003c\/p\u003e\r\n\r\n\u003cp\u003e \u003c\/p\u003e\r\n\r\n\u003ch2\u003e\u003cstrong\u003e📦 The kit includes\u003c\/strong\u003e\u003c\/h2\u003e\r\n\r\n\u003cp\u003e✔️ 1 × Air humidifier \u003cstrong\u003eHE402\u003c\/strong\u003e\u003c\/p\u003e\r\n\r\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e The fan, humidistat, booster pump and air-distribution sleeve are sold separately unless included in a specific configuration.\u003c\/p\u003e\r\n\r\n\u003cp\u003e \u003c\/p\u003e\r\n\r\n\u003ch2\u003e\u003cstrong\u003eBenefits\u003c\/strong\u003e\u003c\/h2\u003e\r\n\r\n\u003cp\u003e✔️ Capacity of up to \u003cstrong\u003e10 litres of humidification per hour\u003c\/strong\u003e\u003c\/p\u003e\r\n\r\n\u003cp\u003e✔️ Suitable for rooms with a volume of \u003cstrong\u003e600–700 m³\u003c\/strong\u003e\u003c\/p\u003e\r\n\r\n\u003cp\u003e✔️ Operates without direct water-mist spraying\u003c\/p\u003e\r\n\r\n\u003cp\u003e✔️ Can be automatically controlled via a humidistat\u003c\/p\u003e\r\n\r\n\u003cp\u003e✔️ Output can be increased with a booster pump\u003c\/p\u003e\r\n\r\n\u003cp\u003e✔️ Helps cool the air during operation\u003c\/p\u003e\r\n\r\n\u003cp\u003e✔️ Easy integration with existing ventilation systems\u003c\/p\u003e\r\n\r\n\u003cp\u003e✔️ Suitable for continuous professional use.\u003c\/p\u003e\r\n\r\n\u003cp\u003e \u003c\/p\u003e\r\n\r\n\u003ch2\u003e\u003cstrong\u003eApplication\u003c\/strong\u003e\u003c\/h2\u003e\r\n\r\n\u003cp\u003eSuitable for:\u003c\/p\u003e\r\n\r\n\u003cp\u003e• Greenhouses\u003c\/p\u003e\r\n\r\n\u003cp\u003e• Seedling production areas\u003c\/p\u003e\r\n\r\n\u003cp\u003e• Ventilation systems\u003c\/p\u003e\r\n\r\n\u003cp\u003e• Climate-controlled rooms\u003c\/p\u003e\r\n\r\n\u003cp\u003e• Storage areas\u003c\/p\u003e\r\n\r\n\u003cp\u003e• Production areas\u003c\/p\u003e\r\n\r\n\u003cp\u003e• Other spaces where optimal air humidity must be maintained.\u003c\/p\u003e\r\n\r\n\u003cp\u003e \u003c\/p\u003e\r\n\r\n\u003ch2\u003e\u003cstrong\u003e📋 Instructions for use\u003c\/strong\u003e\u003c\/h2\u003e\r\n\r\n\u003col\u003e\r\n\t\u003cli\u003eInstall the humidifier in Ø200 mm ducting.\u003c\/li\u003e\r\n\t\u003cli\u003eConnect the unit to a water supply with a minimum pressure of \u003cstrong\u003e2 bar\u003c\/strong\u003e.\u003c\/li\u003e\r\n\t\u003cli\u003eIf necessary, install a booster pump for higher output.\u003c\/li\u003e\r\n\t\u003cli\u003eConnect the fan and solenoid valve to a humidistat for automatic control.\u003c\/li\u003e\r\n\t\u003cli\u003eWhere possible, use an air-distribution sleeve for more even humidity distribution.\u003c\/li\u003e\r\n\t\u003cli\u003ePeriodically clean the evaporative element and keep the system free of dust build-up for optimal performance.\u003c\/li\u003e\r\n\u003c\/ol\u003e\r\n\r\n\u003cp\u003e⚠️ \u003cstrong\u003eImportant:\u003c\/strong\u003e For correct operation, the manufacturer recommends that all electrical components (fan, solenoid valve and booster pump, if fitted) are switched on and off simultaneously via a humidistat.
