The Fail-Safe CHF and CHG
Series are designed to deliver
highly efficient H.I.D. lighting
to clean areas. These units are
ideal for ceiling heights up to
18'. Lower wattages are also
available for standard 8' and 9'
ceilings. Units are enclosed
and gasketed to protect
against the chance of foreign
matter entering high tech
environments through the light
fixture. CHF outside flanged
door is designed to work with
conventional sheet rock or
plaster ceilings. The CHG
housing and door are designed
to work with standard 1" and
1 1/2" T-grid ceilings and most
2" T-grid ceilings. Door frames
feature a gasket design which
eliminates ledge or crevice
exposure preventing the
harboring of contaminants.
These luminaires are U.L.
listed and C.S.A. certified for
wet locations and are
manufactured in accordance
with U.S.D.A., F.D.A., N.S.F.
and Federal Standard 209E.
200 PSI Hose Down Rating is
standard. The CHF and CHG
Series are suitable for use in
I.E.S. Class 100, 1,000, 10,000
and 100,000 clean room
environments.
