Product Overview Section 1.The ATEX Zone 1 2.1kW heater is designed to elevate and maintain the temperature of purge system air within a specified temperature range. Air is passed through a tube that is heated using self-limiting trace heating cable. Switching of power to the air heater is controlled by a capillary tube thermostat. A second thermostat produces an alarm signal when the output air temperature drops below a pre-determined value. System Operation Diagram

Self-limiting Parallel Heating Cable HSB 60 (Source: http://www.bartec.co.uk/)
Description A temperature-dependant resistive element between two parallel copper conductors regulates and limits the power output of the heating tape. This output regulation is carried out automatically along the entire length of the heating tape according to the prevailing ambient temperature. If the ambient temperature rises, the power output of the tape is reduced. This self-limiting property prevents overheating even when the tapes are crossed. Thanks to the parallel design the heating tape can be cut to any required length. This feature considerably simplifies project planning and installation. The heating tape is cut and terminated directly on the construction site according to the circumstances. The heating system must be designed to ensure that the maximum operating temperature of +120 °C will not be exceeded when it is energized. When switched off, the heating tape can be exposed to a temperature of 200 °C for a short time, not more than 1,000 hours cumulated.

Description BSTW II 25-A Ex temperature monitors are two-state controllers in Ex e-certified polyester enclosures. BSTW II can monitor the ambient temperature but also the different surface temperatures. Function Any change in temperature at the sensor bulb causes a change in the volume of fluid in the measuring system, which in turn results in a movement of the diaphragm membrane. This membrane is connected to a mechanical device that activates a microswitch. If the temperature at the sensor bulb exceeds the set value, terminals 1 and 2 are opened. Explosion Protection

Ex d Terminal Enclosure
Ex d terminal enclosures are certified for use in Hazardous Locations, where the Hazardous Location is non-mining (i.e. above ground) and where the hazard is caused by flammable gases, vapours or combustible dusts. The enclosure can be located in Zone 1, 2 for gas and / or Zone 21, 22 for dust, or Class I, Division 1, 2 for gas and / or Class II, Division 1, 2 for dust Hazardous Locations. The joint between the lid and the enclosure forms a threaded flamepath. The following materials are used in the construction of Ex d enclosures. If substances that will adversely affect any of these materials are present in the surrounding environment, please consult EXPO for further guidance.

Installation Section 3.Installation
• Mount the purge system as shown on the Hook-Up drawing. • Always ensure all piping is clean and free of dirt & debris prior to connection to the purge system or
enclosure.
The system shall be installed in accordance with relevant standards, such as IEC / EN 60079-14, and any local codes of practice that are in force.
Air Supply Prior to connecting the air supply to the purge system, flush the supply pipe work with air to remove any debris that may have been introduced into the pipe work during installation. At least 10 seconds for every meter length of supply pipe.
Serial Number The serial number for the unit can be found at the top left corner of the front panel.
Power Supplies and their Isolation Single phase, 210V to 230V supply to the Air Heater is provided by the customer to the Ex d Terminal enclosure via M25 Ex d glanded entry. The supply connection is to be protected by a 13A Type C characteristic circuit breaker, with a means of isolation.
Provision of Alarm Signal When the output temperature falls below a pre-determined set point an alarm signal is removed, i.e. absence of the signal indicates a Low Temperature Alarm condition. There are volt free (dry) contacts available within the Ex d Terminal Box for remote usage.

Commissioning Section 4.Initial Commissioning
• Check that the system has been installed in accordance with Expo Instructions. • Disconnect the pipe from the inlet to the Air Heater and blow clean air through it for at least 10
seconds per meter of length to remove any debris, oil and condensation.
Setting Thermostats The system activation and low temperature alarm thermostats can be set to user requirements. To access the thermostats remove the thermostat access panel as shown in drawing AGM-GM00-464. The switching temperature is set by turning the indicator with a small flat head screwdriver. The System activation thermostat is indicated by a blue dot. The low temperature alarm thermostat is indicated by a green dot.
Commissioning Proceed as follows: • Connect the air inlet pipe to the Air Heater. • Disconnect the pipe from the air outlet and pass air through the Air Heater for 60 seconds. • Reconnect the outlet pipe and check all air connections are fitted correctly with no obstructions. • Energise the power supply to the air heater.
Normal Operation Once commissioned the Air Heater will energise automatically when required, there is no manual override switch provided with the system.
