Temperature control units are essential to ensure precise temperature control in industrial processes. But what happens when these unitas must be installed in ATEX classified environments, where the risk of explosive atmospheres is real? In these cases, the design must meet stringent requirements to ensure safety, reliability and operational efficiency.

There are therefore several challenges for temperature control in ATEX environments:
1. Potentially explosive atmospheres
◦ Flammable dust, gases and vapours can trigger explosions when combined with sparks or overheating.
2. Regulatory compliance
◦ The temperature control units must comply with the ATEX directives (2014/34/EU) and have adequate certifications.
3. Protection from overtemperatures and overheating
◦ The design must avoid the risk of hotspots or ignition sources.

The key design elements in this type of temperature control unit thus involve a series of elements:
– Safe materials and cases
• Watertight stainless steel or aluminum structures to prevent accumulation of dust and gas, in any case ‘certified’.
– Intrinsically Safe control systems
• Electronics and sensors designed to operate in Ex ia (intrinsically safe) regime.
• Use of components certified for ATEX Zone 1 or Zone 2.
– Explosion-proof components
• Use of certified ATEX electrical panels.
• Wiring and connections with special sheaths and certified flame-retardant cables.

A properly designed ATEX control unit for use in potentially explosive environments therefore offers a series of advantages:

• Guaranteed safety: elimination of ignition risks.
• Energy efficiency: optimization of consumption and reduction of waste.
• Operational reliability: continuity of operation in critical environments.
• Regulatory compliance: compliance with ATEX directives and reduced legal risks.

In conclusion, thermoregulation in ATEX environments is a challenge that requires expertise and specialized technologies. An accurate design of the control units not only ensures maximum safety, but also contributes to improving the performance and durability of industrial plants.
