About this product
HOVACO ECH-NI PTX-125/12/1F is a channel electric heater in the ECH NI PTX/PSX family, equipped with power control and air flow control. The device heats clean air in ventilation installations and can work as an initial or secondary heater in a heat recovery system.
Power model 1,2 kW to the channel Ø125 mm allows to supplement the ventilation system with controlled air heating. The 230 V single-phase power supply facilitates the selection of an installation with an appropriate electrical circuit. The suitability of the device is determined by the actual flow of air and the required temperature difference.
The built-in regulator controls the heaters pulsed, matching the time they are attached to the heat demand. The temperature is charged with a potentiometer on the housing. The measurement of the air temperature requires the correct installation and connection of the channel sensor according to the device diagram.
The system contains a PTX flow sensor and PSX differential presostat. In the absence of air flow, the heating is switched off regardless of the temperature behind the heater. Additional protection is provided by two thermostats: the first with automatic reset at 50°C, the second with manual reset at 100°C. After operation of the security, the cause of overheating should be established and removed.
The heater works with the flow provided by the fan or ventilation unit. There's no fan. It may supplement installations in residential buildings, offices, service premises and industrial facilities where clean air is heated. The temperature reached depends on the power, flow and air temperature at the inlet.
The device is designed for internal installations. Horizontal or vertical mounting is permissible, excluding the bottom connection box settings. The instructions shall require air speed of at least 1,5 m/s; the catalogue minimum flow shall be treated together with this condition and the requirements of the particular installation. Air filter is recommended before the heater. It is unacceptable to heat explosive or aggressive gases.
Electrical connection, cable and security selection and grounding should be entrusted to a qualified electrician. The temperature sensor and the presostat must be fitted as instructed. Before buying, compare the channel diameter, power and power type with the installation design.
SAFETY INFORMATION – HAVACO CHEERER
The following information concerns HOVACO ECH NI channel heaters PTX/PSX. Read the instructions provided with the particular device before installation and commissioning.
Destiny
The heater is used exclusively for heating clean air in internal ventilation installations. Do not use it to heat explosive, aggressive or flammable gases.
Edit
Installation should be entrusted to a qualified installer. The device can be installed horizontally or vertically, as instructed. It is prohibited to set the connection box down. Access to control, security and service components must be ensured.
Electrical connection
The connection must be made by a qualified electrician. The voltage, number of phases, wires and protections shall correspond to the data from the data plate. The heater should be grounded. Do not use a device with damaged wire, housing or electrical components.
Required air flow
Do not start heating without air flow. The heater does not have its own fan — the flow is provided by a fan or ventilation unit. The instructions shall require air speed of at least 1.5 m/s. The minimum flow specified for the selected model and the conditions for selecting the installation shall also be taken into account.
Sensors and security features
The temperature sensor, PTX flow sensor and PSX presostat shall be properly mounted, connected and functional. They must not be detached, pinched or avoided. Automatic deactivation of heating in the absence of flow does not replace proper installation and control of the installation.
Protection against overheating
The device has two thermal protections: automatic with 50°C operating temperature and a manual reset with 100°C operating temperature. Before restarting, fix and remove the cause of overheating. Do not reset security multiple times without checking the device and airflow.
Hot Elements
Heating elements and housing parts can cause burns. Do not touch them during work or immediately after turning off. If accidental access to the heaters is possible, appropriate cover shall be used. The maximum output air temperature is 50°C.
Road and cleanness of the installation
Do not block channels or limit airflow. The filter is recommended before the heater. Regularly control the condition of filters, fan and ventilation ducts. Pollution and obstruction can cause overheating.
Maintenance
Before opening the housing, cleaning or service disconnect the power supply, protect against accidental activation and wait for the device to cool down. At least once a year, check the electrical connections and the cleanliness of the heaters and the flow sensor. The work shall be entrusted to persons with appropriate qualifications. Do not flood the device or clean it with a stream of water.
Emergency management
In the case of smoke, the smell of burning, damage to the installation or repeated operation of security, stop the use and safely disconnect the power supply. Do not restart the heater before removing the fault by qualified service.
Transport and storage
Protect the device from impact, moisture and excessive load. Do not lift it for wires, hoses or automation elements. Store in a dry place, in accordance with the conditions set out in the instructions.
