The heaters have a rubber seal for an airtight connection to the ventilation ducts. NK duct heaters are equipped with two thermostats to protect against overheating:\u003c\/p\u003e\n\u003cp\u003e- Main protection with automatic restart (start-up temperature from +50ºC).

Each size of the heater comes in several variants with different power. Increasing the power can be achieved through serial installation of heaters. All three-phase heaters connect with each other according to the “star” scheme.\u003c\/p\u003e\u003ch2\u003eChannel heater NK...U with built-in temperature control.\u003c\/h2\u003e\n\u003cp\u003eIn order to automatically maintain the set air temperature, the NK...U option was created with a temperature control module (from 0,6 to 2,4 kW) or a control block (from 3,0 to 9,0 kW).\u003c\/p\u003e\u003ch2\u003eNK...U heater design with control block (from 3,0 to 9,0 kW).\u003c\/h2\u003e\u003cp\u003eThe NK...U heater with control block is equipped with a triac power regulator. The adjustment consists in turning the full load on and off. The heater allows you to maintain the temperature in the range from -30*C to +30*C. A semiconductor device (triac) is used to switch the load. This means that there are no mechanical components in the device that are exposed to wear and tear. Load switching always occurs when the current and voltage are zero, which excludes the appearance of electromagnetic interference.\u003c\/p\u003e\u003cp\u003eNK...U heaters have two thermostats to protect against overheating:\u003c\/p\u003e\n\u003cp\u003emain protection with automatic restart (start-up temperature from +50ºC).

An external control signal from the second controller with a voltage change range (0-10 V) can be connected to the regulator, which corresponds to the temperature in the channel (0...+40°C).\u003c\/p\u003e\u003ch2\u003eInstallation\u003c\/h2\u003e\n\u003cp\u003eThe design of the heater allows you to place it in round ventilation ducts with buckles. The direction of movement of the air must correspond to the arrow on the heater. Duct heaters can be set in any position, except for the position of the distribution board downwards (danger of condensation accumulation). It is recommended to set in which the air flow flows evenly throughout the cross-section. In front of the heater there should be an air filter, protecting the heating elements from dirt. The recommended distance between the heater and other elements of the system should be not less than the diagonal of the heating element in the flow part. The efficiency of duct heaters is calculated at a minimum air flow rate of 1,5 m\/s and a maximum outgoing air temperature of +40ºC. When using a fan speed controller, it is necessary to ensure the minimum efficiency of air flowing through the heater. The heater cannot work with the fan off.\u003c\/p\u003e\u003ch2\u003e\u003cb\u003eDimensions \u003c\/b\u003e\u003c\/h2\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eGroup\u003c\/th\u003e\n\u003cth\u003eName\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eParametry\u003c\/td\u003e\n\u003ctd\u003eCondition\u003c\/td\u003e\n\u003ctd\u003enew\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eParametry\u003c\/td\u003e\n\u003ctd\u003eInvoice\u003c\/td\u003e\n\u003ctd\u003eWith VAT invoice\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eParametry\u003c\/td\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eVents\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eParametry\u003c\/td\u003e\n\u003ctd\u003eKind\u003c\/td\u003e\n\u003ctd\u003eelectric\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eParametry\u003c\/td\u003e\n\u003ctd\u003eHeating power\u003c\/td\u003e\n\u003ctd\u003e3.4 kW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eParametry\u003c\/td\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eNK 160-3,4-1 U\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eParametry\u003c\/td\u003e\n\u003ctd\u003eProduct weight with unit packaging\u003c\/td\u003e\n\u003ctd\u003e4.6 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eParametry\u003c\/td\u003e\n\u003ctd\u003eManufacturer code\u003c\/td\u003e\n\u003ctd\u003eNK 160-3,4-1 U\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eParametry\u003c\/td\u003e\n\u003ctd\u003ePackaging status\u003c\/td\u003e\n\u003ctd\u003eoriginal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eParametry\u003c\/td\u003e\n\u003ctd\u003eEnergy efficiency class\u003c\/td\u003e\n\u003ctd\u003ebrak klasy energetycznej\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eParametry\u003c\/td\u003e\n\u003ctd\u003eRange of energy efficiency classes\u003c\/td\u003e\n\u003ctd\u003eno energy class\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"TNL_2020","offers":[{"title":"Default Title","offer_id":53597737419099,"sku":"16632616950","price":404.89,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0954\/9355\/4523\/files\/Electric-duct-heater-NK-160-3-4-1-U-with-automation-3-4kW-fi-160.jpg?v=1784104462","url":"https:\/\/homy.lt\/products\/elektrinis-ortakio-sildytuvas-nk-160-3-4-1-u-su-automatika-3-4-kw-160","provider":"homy.lt","version":"1.0","type":"link"}
