3 INTRODUCTION In chemical, petrochemical, process, offshore industry and military installations various media are produced, processed and stored in areas where there is a potentially explosive atmosphere, which necessitate explosion proof electrical heaters. Our explosion proof heaters comply with ATEX which is an EU directive concerning electrical and mechanical equipment for application in hazardous areas. We manufacture electric heating solutions for solids, liquids and gases complete with control and instrument panels or cabinets, such as: immersion heaters (liquids, gases) immersion heater batteries (liquids, gases) circulation heaters (liquids, gases) gas heaters (industrial gases, such as hydrogen natural gas, carbon dioxide, nitrogen, etc.) air heaters ovens miscellaneous industrial heating applications control and instrument panels, cabinets, thermostats, electronic temperature control, thyristor and microprocessor control. Incidental presence of explosive mixtures during a very short time Danger of ignition No danger / GENERAL Technological developments and safety regulations makes it almost possible to avoid the danger of explosions. The term explosive atmosphere is defi ned as a mixture of infl ammable solids in the form of gases, vapour, fog or dust with air under atmospheric conditions causing the combustion to spread to the entire unburned mixture after ignition. Atmospheric conditions are normally defi ned as 0ºC to +40ºC, pressure 0.8 to 1.1 bar. Electrical units for hazardous areas are spit up in two groups: GROUP I Group I consists of electrical devices applied in explosive atmospheres in areas such as gasworks and mining. Devices categorised as group I are applicable when the danger of explosion is caused by methane, coal dust or a mixture of these. In case that coal dust forms a layer on the device a maximum surface temperature of 150ºC is admissible. When the deposit of a coal dust layer is not possible a maximum surface temperature of 450ºC is allowed. No danger / 1/1 0/0 1/1 / No danger Regular presence of explosive mixtures Continuous presence of explosive mixtures GROUP II Electrical devices in hazardous environments (excluding group I) above ground level. For this group the admissible surface temperatures only count for executions of devices which meet the requirements of the temperature classes. ZONE CLASSIFICATION Hazardous areas include places, environments, premises and operational circumstances where explosive atmospheres can be present. To indicate the probability of explosion in the above mentioned hazardous areas, these are divided into zones; zones for gases and zones for dust depending on how often the danger of explosion is present. ZONE 0 are areas where danger of explosion is always or very often present due to infl ammable solids in the form of gases, fog or vapour. ZONE 1 are areas where danger of explosion is occasionally present under normal operating conditions due to infl ammable solids in the form of gases, fog or vapour. ZONE are areas where danger of explosion is rarely or only shortly present due to infl ammable solids in the form of gases, fog or vapour. ZONE 0 are areas where danger of explosion is always or very often present due to infl ammable solids in the form of dust. ZONE 1 are areas where danger of explosion is occasionally present under normal operating conditions due to infl ammable solids in the form of dust. ZONE are areas where danger of explosion is rarely or only shortly present due to infl ammable solids in the form of dust. SINUSJEVI Electric Heating BV Nijverheidsweg NL171 GC Medemblik

4 4 INTRODUCTION GAS CLASSIFICATION Gas ignition danger determines whether to use gas classifi cation A, B or C. Classifi cation B also applies to classifi cation A, and classification C applies to both A and B. TEMPERATURE CLASSES For an optimal application of explosion proof electrical equipment a distribution in temperature classes has been developed to prevent immediate applications of the most strict safety regulations. The lowest ignition temperature of an explosive gas or vapour mixture in which electrical equipment is installed should exceed the surface temperature of the device. The highest admissible surface temperatures are applied for temperature group T1; the lowest for temperature group T. An electrical heater which fulfi lls the requirements of temperature class T4 automatically meets the standards of T1, T and T. TEMPERATURE CLASS T1 Gas or vapour mixtures with an ignition temperature >450ºC and a maximum admissible surface temperature of the electrical device of 450ºC. T1 includes e.g.: propane, carbon monoxide, ammonia, acetone, benzene, methane, hydrogen. TEMPERATURE CLASS T Gas or vapour mixtures with an ignition temperature >00ºC and a maximum admissible surface temperature of the electrical device of 00ºC. T includes e.g.: butane, butyl acetate, ethanol, isopentane. TEMPERATURE CLASS T Gas or vapour mixtures with an ignition temperature >00ºC and a maximum admissible surface temperature of the electrical device of 00ºC. T includes e.g.: petrol, oil derivatives, in principal petrochemical industry. TEMPERATURE CLASS T4 Gas or vapour mixtures with an ignition temperature >15ºC and a maximum admissible surface temperature of the electrical device of 15ºC. TEMPERATURE CLASS T5 Gas or vapour mixtures with an ignition temperature >100ºC and a maximum admissible surface temperature of the electrical device of 100ºC. T5 derives its practical meaning in the processing of carbon disulphide and the production of textile fi bres. TEMPERATURE CLASS T Gas or vapour mixtures with an ignition temperature >85ºC and a maximum admissible surface temperature of the electrical device of 85ºC. T is based only on the processing of ethylnitrite. The environmental temperature in the calculations is 40ºC. An environmental temperature which deviates from the above mentioned 40ºC is admissible. In this case the chosen temperature must be mentioned explixitly on the device. Temperature Class T1 T T T4 T5 T Max. Surface Temperature 450ºC 00ºC 00ºC 15ºC 100ºC 85ºC Upper explosion limit No explosion concentrate volume too high Ignition area Explosion of ignition source is present Lower explosion limit No explosion concentrate volume too small Safe area JEVI A/S Godthåbsvej 7 DK7100 Vejle

5 INTRODUCTION 5 FLAMEPROOF ENCLOSURE d Cenelec EN Electrical parts which in a hazardous atmosphere can ignite an explosion should be enclosed in a junction box. The junction box has to be constructed in such a manner that it can resist the pressure built up of an explosion (dampening effect) and prevent transmission of the explosion to the environment. It is assumed that penetration of explosive gas or vapour in the closure cannot be prevented, but the explosion will then be limited to the inner part of the enclosure, i.e. limited to the ignition source itself (sparks, arcing). Flameproof enclosures can be classifi ed as A, B or C the safety requirements for B are more strict than A, and the same applies to C in comparison with B. The fl ameproof junction box undergoes an overpressure test which differs in relation to type A, B or C. The aim of the test is to fi nd out if the junction box can resist the test pressure as the gas mixture cannot escape from the enclosure. Based on this, the offi cial institute determines if the fl ameproof enclosure complete with heating elements will be admitted and certifi ed. INCREASED SAFETY e Cenelec EN For this method of protection special measures have been taken in the construction to create the possibilities of increased safety in order to prevent high surface temperatures as well as preventing sparks and arcing in the inner and outer parts of the electrical device. The essential difference between the enclosure d and e is that in enclosure e an explosion is completely excluded. The maximum surface temperature is the determining parameter. Junction boxes, control cabinets with electrical parts under voltage have to be executed with IP54 protection. In constructions which only enclose insulated electrical parts IP44 executions are suffi cient. EEX de II C T Defi nes max. surface tem pe ra tu re on parts placed in the ex area.

6 INTRODUCTION For hazardous areas we have developed explosion proof EEx de heating equipment, designed and manufactured in accordance with EN , EN and EN certifi ed by the independent testing institute ISSeP. The certifi cates cover zone 1 and zone for hazardous areas as well as gas groups II A, II B and II C and temperature classes TT1. The flameproof d enclosures have been designed for nonsafe areas to protect the environment against gas explosions caused by sparking of electrical connections of the heating elements and control devices. Several types of enclosures for immersion heaters, fl anged or screwed, have been described on pages 810. Each type covers a range of maximum number of installed hairpin shaped heating elements and therefore a range of installed power. By consulting the selection tables on pages 810 it is easy to select the heating equipment for your specifi c application. The terminal enclosures have a certifi ed degree of protection up to IP. As standard the enclosure is coated with one layer of primer and one topcoat. Other coating systems on request. The maximum temperature for the terminal enclosure during operation is 80ºC (based Max. Temperature of Flange 85ºC 100ºC 15ºC 00ºC 00ºC 450ºC on maximum 40ºC ambient temperature). The required minimum distance between enclosure and connection fl ange to ensure the temperature limit of 80ºC in the enclosure is listed in the below table as a function of temperature classes. The enclosures have been provided with cable entry sockets for certifi ed standard cable entries. The quantity, size and type of cable should be stated when ordering. Please send your data requirements and we will quote a custombuild piece of heating equipment.

7 BASIC COMPONENT 7 EEx e II HEATING ELEMENT A basic component within explosion proof heating equipment is the tubular heating element. The heating element consists of a nickelchrome resistance wire, centred in a metal sheath and insulated with compact magnesium oxyde. The elements are usually bent into a hairpin shape. Standard diameters of the element: 8.5 mm, 10. mm,.7 mm and 1 mm. Sheath material: AISI 04/1/1/10 Incoloy 800/85, Inconel 00 Titanium, copper We have designed an increased safety heating element with code EEx e II according to Cenelec standard EN and EN This heating element forms the basic of increased safety heating equipment. Increased safety is a method of protection by which additional precautions have been taken with regards to construction (to create the possibilities of increased safety) in order to prevent high surface temperatures as well as sparks and arcing in the inner and outer parts of the electrical parts. These EEx e II elements can be built into a junction box with minimum degree of protection IP54 provided with EEx e terminals to an increased safe immersion heater. For maximum temperature protection and controlling certifi ed fl ameproof thermostats and thermocouples or intrinsically safe performed thermocouples a junction box can be installed. All switching devices in the junction box must be fl ameproof performed. The distance between the junction box and fl ange in relation to the temperature class T to T1 is shown in the table on page. The increased safe heater batteries can be applied in hazardous areas, zone 1 and zone and installed in air duct systems and in special applications in which the fl ameproof batteries are beyond their scope. Delivery of the increased safe heating equipment includes all necessary certifi cates of the components. SINUSJEVI Electric Heating BV Nijverheidsweg NL171 GC Medemblik

20 0 CONTROL EQUIPMENT CONTROL CABINETS Most heating units are supplied by us together with a total control system. To ensure complete compatibility and optimal design the complete engineering and manufacturing of both heating unit and control system is preferable. The efficiency of each heating system depends on the ability to control it accurately. Therefore, we have developed large expertise in offering the best solution for controlling each heating system application. A full range of control systems is available for hazardous areas utilising EEx d, EEx de and EEx p types of protection. The types of control for electric heating systems in hazardous areas include: ONOFF CONTROL For applications where accurate control is not essential the onoff control is suitable. Onoff control switches the entire heater load either on or off. The control devices can be thermostats or for slightly improved accuracy electronic controllers with a resistance thermometer PT100 or thermocouple as sensor. For loads above the switching capacity of thermostats or controller the load is switched via a contractor. STEP CONTROL For more accurate control than onoff and for controlling high load heating systems step controlling is advisable. The heater load is divided into a number of steps. Each step is switched by a separate contactor. Depending on the temperature difference between setpoint and process temperature the step controller selects the number of steps to be switched on. THYRISTOR CONTROL For high accuracy of control thyristor units are used. PHASE ANGLE CONTROL (p) Each thyristor is triggered once in every half cycle of the AC supply conducting ceasing at the end of the half circle as the current falls to zero. In this way the supply wave form is chopped resulting in a reduction on the RMS output of the thyristor stack. PhaseAngle fi red thyristors give smooth, stepless control of the applied voltage, they are very suitable for heating elements with a large resistance difference between cold and operating temperature. TIME BASED ZERO VOLTAGE SWITCHING (z) The thyristors are triggered at the beginning of a mains cycle and remain conductive for one or more complete cycles before being switched off for one or more cycles. This operation is continuously repeated thus limiting the average power input to the elements. Slow cycle thyristors generally have cycle times of several seconds and are not suitable for direct control of heaters with a great difference of the resistance between cold and operating temperature. CYCLE BASE ZERO VOLTAGE SWITCHING (c) The optimum type of burstfi red thyristors is the singlecycle burstfi ring type where the average power input is always reached over the minimum possible number of complete cycles (i.e. 50% power = cycle»on«+ 1 cycle»of«). Resistive loads controlled by fastcycle thyristors have a unity power factor and as only full mains cycles are delivered to the load there is no cumulative distortion of the mains supply. With heavy loads however, voltage drop may cause fl ickering lights and also affect sentive equipment. COMBINATION OF THYRISTOR UNITS For very large loads or when the heater represents a signifi cant proportion of the power generation capacity, the heater load is divided into a number of small units each controlled by its own thyristor. A synchronising card control ensures that each thyristor is turned on and off consecutively during the set time period. There are no peak loads generated by a simultaneous controller action and load valeys are evened out. Please contact our technical department for detailed information.
