UE Reference Standards
All AMARC heating cabinets come within the field of application of Machinery Directive 2006/42/EC and refer to harmonised standards and European standards as regards the safe construction of machinery.
Machinery Directive 2006/42/EC; standards EN12100, EN60204-1, EN13849-1, EN62061, EN61508-1, 2, 6.
All heating cabinets supplied with Steam, Hot water, Diathermic oil fall within the field of application of Directive 2014/68/EU – pressure equipment “Article 4, paragraph 3”.
On request, AMARC designs and constructs piping line for heating cabinets running on Steam, Hot water, Diathermic Oil in accordance with the ASME Directive.
All heating cabinets that require explosion-proof protection (whether only for the internal zone or for the internal and external zone) fall within the field of application of ATEX Directive 2014/34/EU and refer to harmonised standards and European standards as regards safe construction of machinery.
ATEX Directive 2014/34/EU; standards EN60079-14, EN50495.
The design of safe heating cabinets becomes as important as the mechanical sturdiness or the process efficiency.
All AMARC heating cabinets are equipped with the following devices.
- Proximity sensors for stopping the machine when the doors open: By stopping ventilation they prevent the operator from being struck by air flows at high temperatures and by undesirable fogs.
Th safety systems meant for monitoring the mobile guards and doors are designed and constructed in accordance with Harmonised European Standards EN60204-1.
- Anti-entrapment systems: AMARC heating cabinets are fitted with doors that can be opened from inside with anti-entrapment function.
Th safety systems meant for monitoring the mobile guards and doors are designed and constructed in accordance with Harmonised European Standards EN60204-1, EN13849-1.
- Alarms Light Signal: All the alarms are diagnosed by a special light signal on the control panel and cumulated by the light column installed on the roof of the enclosure or on board the machine. These are provided on request, can be remote connected in the terminal board for connection to the customers’ central supervision systems.
The light signal systems are designed and constructed in accordance with Harmonised European Standard EN60204-1.
- Emergency button, under Safety relay: A red “mushroom” shaped emergency pushbutton is installed on all the control panels which stops all the functions of the machine in the event of an emergency.
This device, which is directly connected to a Safety relay.
The systems for emergency stop by means of mushroom shaped button are designed and constructed in accordance with Harmonised European Standards EN60204-1, EN13849-1.
- Hazardous temperatures mitigation systems: All AMARC heating cabinets are provided with safety circuits against overtemperatures with two thresholds:
- “High Temperature”, act to stop the machine.
- “Extremely high Temperature”, acts by giving the signal on the temperature regulator and emitting a signal, on voltage-free contact, can be controlled by installers to implement fire control and firefighting actions.
For all ATEX heating cabinets (only internal zone or internal/external zone) a circuit is provided against “surface overtemperatures” of the heaters (on the basis of the ATEX temperature class) . The systems for mitigation of hazardous temperatures (for the purpose of the system as well as for the prevention of explosion, if necessary) are designed and constructed in accordance with European Harmonised Standards EN60204-1, EN62061, EN50495, EN61508-1,2,6.
This design was completed with the drafting of a “Safety Assessment Report” (SAR), which determined the performance level of the aforementioned safety circuits as follows:
- SIL 2 for all ATEX cabinets (internal zone only or internal/external zone)
- SIL 2 for all cabinets with electric heating for safe zone
- SIL 1 for all heating cabinets with heating by steam, diathertmic oil, hot water for safe zone
