APPLICATION
Designed specifically for heating industrial spaces where potentially
explosive substances are or may be present. Typical hazardous
location environments include:
• Water and Sewage Treatment Plants
• Oil Refineries
• Compressor Stations
• Pulp and Paper Mills
• Paint Storage Booths
• Cement Plants
• Mines
CONSTRUCTION AND INSTALLATION
CCI Thermal’s
NORSEMAN™ unit heaters use extra heavy wall
finned tubular steel heating elements to provide safe, efficient heat
transfer to the environment. The heater does not contain glycol,
decreasing maintenance costs.
Flow adjustment… in structures with high ceilings, other units may
not have the range of motion needed to direct air flow to the floor.
The glycol-free design of the
XGB allows the unit to be tilted to
a 30º angle below the horizontal, with an additional 35º of airflow
redirection provided by the outlet louver. For lateral airflow, the
entire louver assembly can be rotated 90º.
No conduit seal required… a factory installed conduit seal provides
the necessary isolation between the supply and control housings.
In Division 2, Zone 1 and Zone 2 applications, a field installed
conduit seal may not be required.
Simplified wiring… to facilitate installation, the NORSEMAN™
explosion-proof unit heaters feature the patented
x-Max
®
housing
with slide out terminal block trolley for connection of the electrical
supply.
