The Systemair CB 355-12.0 400V/3 Round Duct Heater is a powerful and reliable electric heater designed for heating air in standard spiral ventilation ducts. Built with durable Aluzinc-coated sheet steel and a stainless steel heating element, this duct heater ensures efficient heat transfer and long-lasting performance in HVAC systems. It features integral overheating protection with a manual reset function for enhanced safety during operation. The heater includes rubber seals on the connecting spigots to help create a secure and airtight duct connection. Designed to operate with room thermostats or Pulser controllers, the unit requires a minimum airflow based on an air velocity of 1.5 m/s and delivers a maximum output air temperature of 50°C. It can be installed in both horizontal and vertical ducts; when installed horizontally, the connection box must face upward or be rotated 90° to the side to maintain safe operation.
