Hazloc XEU1-20 explosion proof electric air heater is a CSA certified hazardous area heater specifically designed to meet the demanding requirements of the explosive atmosphere industries – see IECEx and ATEX explosion proof heaters for models certified according international and European classifications.
The harsh operating conditions of hazardous area locations require electric heating equipment that is safe, reliable, dependable.
The Hazloc XEU1 range of electric air heaters are designed to provide either primary or supplementary heating for comfort or for freeze protection in areas that are classified by CSA as hazardous locations (Gas and Dust atmospheres).
Hazloc Heaters XEU1 models have been designed to meet U.S. and Canadian (CSA) certification standards and the spark-resistant fan assembly is also compliant to AMCA 99-10, Type B.
There are three sizes of air heater in the XEU1 range, all of which feature ExCaliber high performance liquid-to-air heat-exchanger cores.
These are available in thirty five models, all with varying voltage and heat output combinations to meet the specific requirements of the end user.
ExCaliber Liquid-to-Air Heat-Exchanger Cores
All XEU1 ExCaliber liquid-to-air heat-exchanger cores are evacuated, sealed and constructed using rugged carbon-steel tubes with copperfree, roll-formed aluminium fins in order to maximise heat transfer and carbon-steel headers for maximum durability, resistance to corrosion, and a longer life in demanding applications. The cores are protected by a pressure relief device, automatic reset high limit, and a back-up manual reset high limit.
The XEU1 heater has the highest air temperature rise, on average, in the industry across the complete kW range. ExCaliber heat-exchanger core is easy to remove when required.
