EMS - HEATERS FOR MOUNTING INSIDE AIR HANDLING UNITS Used internally in air handling units, these heaters are designed and manufactured per project basis, as every project might require different parameters. Frame is made using Aluzinc coated steel, which is highly resistant to corrosion. Heating elements are made from stainless steel AISI304. All heaters are made with thermal protections- automatic at 50°C and manual- 100°C. These heaters do not have limits on size and power output, therefore please contact our sales team with an inquiry for an offer or partnership possibilities. We are in Aircalc++ AHU builder. Without internal controls, the heater is controlled via external controller. Possibility to add internal contactors, alarm signal. Higher capacity heating output is divided between steps. Heater controller for single and two-phase electric heaters. Controls by supply* or room temperature. Has an internal temperature sensor in casing, supply air temperature sensor is required for operation in both modes. Controller for three-phase electric heaters with power up to 240kW. Controls by supply or extract air temperature sensors* or an external 0..10VDC control signal. Extra steps activated by sequential or binary mode, depending on heater power. PS – mechanical protection against loss or insufficient airflow with differential pressure switch. The heater if not allowed to heat unless a minimum airflow of 1,5m/s is reached. By ordering the PS, an internal contactor for power supply is added to the heater as well. Upon request internal contactor for power supply can be added the heater. Internal NO and NC alarm contacts added to the heater.
