With a 39kW heating capacity and a 400V three-phase power supply, this duct heater ensures efficient heating while maintaining stable airflow. The unit features a durable alu-zinc coated steel casing for corrosion resistance and long service life, while the internal heating elements are constructed from stainless steel for optimal heat transfer and durability. Built-in overheating protection with a manual reset enhances safety and system reliability. Designed for use with TTC controllers and TT-Slave modules, the heater operates with a minimum air velocity of 1.5 m\/s and is engineered to maintain a maximum outgoing air temperature of approximately 40°C, making it ideal for controlled air heating in ventilation systems.\u003c\/p\u003e","brand":"Puravent","offers":[{"title":"Default Title","offer_id":53422971617617,"sku":"5449","price":1895.04,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0982\/4098\/7473\/files\/28_1_ea015347-b5fa-4cb3-98e0-da0238e538bd.jpg?v=1774989913","url":"https:\/\/veralis.co.uk\/products\/systemair-rbk-66-39-rectangular-duct-heater-39kw-electric-heater-battery-660-x-660mm-400v-3-phase-stainless-steel-heating-elements-overheat-protection-alu-zinc-steel-casing-product-code-5449","provider":"Veralis","version":"1.0","type":"link"}
