Hazloc XEU1 explosion proof electric air heater is a CSA certified hazardous area heater specifically designed to meet the demanding requirements of the explosive atmosphere and hazardous area industries.
Hazloc XEU1 explosion proof electric air heater is a CSA certified hazardous area heater specifically designed to meet the demanding requirements of the explosive atmosphere and hazardous area industries.
The harsh operating conditions of heavy industry require electric heating equipment that is safe, reliable, dependable and certified according to the hazardous area classification.
XEU1 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) – see IECEx and ATEX explosion proof heaters for models certified according international & European classifications.
All 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 Hazloc XEU1 range, all of which include 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.
The XEU1 electric air heater is rugged and versatile and incorporates a high quality immersion heater, high performance fan and motor assembly, a sturdy 14 GA steel cabinet with a yellow epoxy/polyester powder-coating for corrosion resistance, a large control enclosure with an extra port for convenient wiring of an external room thermostat and enclosure O-rings to minimise any ingress of moisture.
XEU1 heaters are suitable for a wide variety of applications which include, but are not limited to, oil & gas drilling rigs, petrochemical facilities, refineries, chemical storage and handling facilities, paint storage areas, sewage treatment plants, aircraft servicing areas, grain elevators, coal preparation areas, and other areas which are subject to combustible dusts such as flour, wood, plastics or chemicals.
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.
