Ice Qube has been manufacturing hazardous location products since 2003 and today Ice Qube offers an innovative full line of closed-loop Class I Division 2 heat exchangers, ranging from 5.7 to 83 W/°F (10.3-149.4 W/°C), without a bulky and expensive NEMA 7 flameproof enclosure. This line is also available for Zone 2 locations with ATEX/IECEx certifications and ranges from 5.7 to 83 W/°F (10.3-149.4 W/°C). Ice Qube’s hazardous location heat exchangers do not rely on a purge system to maintain certifications and run safely in a hazardous environment.
Ice Qube’s hazardous location heat exchangers all have the same features as our general-purpose line of heat exchangers but with added protection to meet the certified requirements of UL, ATEX, and IECEx for the respective environments of Class I Division 2 and Zone 2 locations. These environments include process control systems for chemical, petrochemical, refining, field drilling, offshore drilling, and more.
Class I Division 2
Class I Division 2 is an area where explosive gases, vapors or liquids are not present under normal operating conditions. In a Class I Division 2 area the gas, vapor or liquids are only present under abnormal or unlikely conditions (a leak). Class I Division 2 Certifications that Ice Qube provides for our customers include: UL, ETL, CSA, EAC, and SASO.
Zone 2 is an area where explosive gases, vapors or liquids are not present under normal operating conditions. In a Zone 2 area the gas, vapor or liquids are only present under abnormal or unlikely conditions (a leak). In a Zone 2 area, unwanted substances can only be present under 10 hours/year or 0-0.1% of the time to be considered a Zone 2 location. Zone 2 Certifications that Ice Qube provides for our customers include: ATEX, IEXEx, CSA, EAC, and SASO.
Closed-loop cooling is the process of taking heated air into the heat exchanger, from the enclosure/application, by a powerful blower/fan where heat is removed as it passes through the Multi Surface Cold Core. The air is then recirculated back into the enclosure/application. This process of cooling maintains the NEMA and/or purged integrity of the enclosure/application.
*All of Ice Qube’s products are independent agency tested, listed, and/or certified. Before our products are sent out for testing at independent agencies, Ice Qube utilizes our multiple in-house testing chambers. Our in-house testing chambers ensure that all our products meet and/or exceed independent agency testing standards before independent agencies verify all testing.
Typically, other manufacturers of enclosure cooling systems send their standard units to be converted for hazardous location applications. However, the companies that do the conversion may have to make changes that can affect the efficiency of the original unit. Often, components are substituted or added that may influence the cooling capacity or useful life of the original system.
*Ice Qube hazardous location heat exchangers are specifically designed, and factory built to insure product integrity, reliability, and safety. Ice Qube’s hazardous location heat exchangers are built and engineered from the start for hazardous locations. Ice Qube does not repurpose general purpose heat exchangers for hazardous location areas.
Remember to ask yourself if it's not an Ice Qube Hazardous Location Heat Exchanger: WHO IS RESPONSIBLE FOR REPAIRING THE UNIT SINCE THE ORIGINAL MANUFACTURER MAY NOT BE CERTIFIED TO REPAIR A CONVERTED UNIT?
