Electrical duct heaters
The electrical duct heaters are HVAC devices used to heat air in ducts. The casing and housing of the air heaters are made of galvanized sheet steel as standard. Installation and placement of the electrical heaters is possible in circular and four-sided ducts according to the requirements for power and control of the heater.
The electrical heaters for HVAC ducts can be supplied with a built-in heating output control with the possibility of setting the outlet temperature up to the control of several-row heaters with sectional switching. As standard, the electrical heaters are equipped with safety thermostats. It is necessary to observe the minimum air speed and cooling of the heating rods after switching off. The installation and location of the electrical air heaters must be unconditionally carried out in accordance with ČSN 33 2000-4-42 (IEC 364-4-42).
Water duct heaters
The water-heating batteries are designed for four-sided or circular ducts. The casing of the water-heating batteries is made of galvanized sheet metal, the fins are made of aluminium on copper tubes. The water-heating batteries for air ducts are supplied according to the power requirement and the supplied temperature gradient of the heating register. The output can be regulated thanks to several row heaters with switching by heater sections.
The water-heating batteries are mounted approx. 1 m behind a fan. If the water-heating batteries are installed in front of a fan, it is necessary to determine whether the outlet air temperature does not exceed the permitted operating temperature of the fan. The connection is made with a collet adapter with a thread that is not included in the delivery by means of soldering according to the production line. The water-heating batteries are equipped with a drain and vent valve as standard.
