HAVACO ECH-NI PTX/PSX electric duct heaters
ECH NI PTX/PSX HAVACO is a series of electric duct heaters with a built-in automation system containing a heater power regulator and a flow sensor (PTX) and pressure switch (PSX). The control is based on the pulsation principle. The time between switching on and off the heaters is adjusted by the controller so as to ensure that the set temperature value is maintained. Temperature setting is carried out by a potentiometer located on the heater housing. In the absence of air flow, the heating function is switched off, regardless of the air temperature behind the heater. ECH heaters are designed for installation in circular ducts. They are available in typical ventilation diameters from 100 to 500 mm and powers from 0.3 to 24.0 kW.
Each heater has a two-stage overheating protection:
- I stage at 50°C - automatic reset.
- II stage at 100°C - manual reset required.
