1.0 GENERAL INFORMATION

DESCRIPTION

CCI Thermal’s XGB explosion-proof unit heater is the latest addition

to the NORSEMAN™ line of hazardous location heating products.

The small cabinet units are available with ratings from 3.75 – 10kW,

and can be identied by their internally mounted motor. The large

cabinet units (shown below) are available from 10kW up to 35kW.

See section 3.1 for cabinet dimensions.

APPLICATION

Designed specically for heating industrial spaces where potentially

explosive substances are or may be present. Typical hazardous

location environments include:

• Water and Sewage Treatment Plants

• Oil Reneries

• 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

nned tubular steel heating elements to provide safe, efcient 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 ow to the oor.

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 airow

redirection provided by the outlet louver. For lateral airow, 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 eld installed

conduit seal may not be required.

Simplied 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.
