Duct heaters with circular connections and hot water as energy medium
Circular duct installation horizontaly or verticaly
Corrosion protected casing
Air tightness class D
Removable access panel for inspection and cleaning
The VBC water heating battery is designed to be inserted into standard spiral ducting and can be installed in horizontal or vertical position with an optional direction of airflow.
VBC duct heaters meet air tightness class D as per EN 15727, which ensures that the heated air reaches its destination and does not leak out of the ventilation system that saves both energy and money.
Casing of VBC made of Zinc Magnesium-coated sheet steel (ZM 310) to provide high corrosion protection.
To facilitate easy cleaning and maintenance, the VBC water heating battery features a removable access panel.
Application: The VBC water heating battery is designed to use hot water as an energy medium and is used to heat up the ventilation air in a ventilation system with circular ducts.
Design: Casing made of Zinc Magnesium-coated sheet steel, ZM 310. Coil with copper pipes and pipe connections as well as aluminium fins. Removable access panel for easy inspection and cleaning. Duct connections are fitted with rubber gaskets. VBC duct heaters meet highest air tightness class D as per EN 15727.
Installation: Can be installed in a horizontal or a vertical duct with the air flow in any direction. It is also designed to be inserted into standard spiral ducting and is fixed to the ducting with screws. If the VBC water heating battery is being used in cold conditions, then it should be fitted with a frost protection device with a sensor to reduce the risk of damage from freezing. The heater must be installed so that the removable access panel are accessible for cleaning.
Operating Data: Maximum operating temperature of 150 °C and a maximum operating pressure of 1,0 MPa (10Bar). All the coils are pressurised and leak tested.
Control: Unit capacity can be controller on demand by using recommended acccessories - controllers, various sensors, vavles and actuators to provide regulation of the room or supply air temperature.
Maintenance: The water heating battery is fitted with a removable cover to facilitate easy cleaning and maintenance. The heat exchanger must be cleaned regularly in order to retain the best performance from the heater. Cleaning is facilitated by using a mild detergent. An effective filter is recommended in the system to reduce maintenance work.
