World Leader in Flameless
Gas Infrared Catalytic Heaters
to Prevent Pipeline Freezing
• Gas Production
• Transmission pipelines
• Distribution Systems For more than 40 years, Bruest Catalytic Heaters
has led the industry in manufacturing catalytic
heater equipment to prevent freeze-ups in critical
metering and regulating equipment, and to heat
meter buildings, platforms and pipelines. Bruest
products are ideal for flammable products storage
and compressor buildings where there's a
hazardous condition. In 2003, Bruest introduced a revolutionary,
and now field-proven technology to prevent
pipeline freezing: HotCat. HotCat is quiet and energy-efficient, and is
approved for Class 1, Division 1 & 2, Group D
areas. Some of North America’s most prominent
utilities now use HotCat technology to prevent
pipeline freezing without the hazard, chemical cost
and maintenance of water bath devices. And,
without the environmental and liability problems
that come with ethylene glycol heaters.
Recently, three other important systems were
introduced. Based on the same operational
principles, a new, space-saving HotCat
prevents pipeline freezing where space is at
a premium. This slimmed-down HotCat system
has manual control and is available in 60” to
125” models. For high pressure cut, low flow applications,
Bruest engineered Super Freez-Fiter
pipeline heaters.
And, in late 2009, Bruest introduced the
Freez-Fiter Plus pilot heater, which is
also ideal for in-line heating and the heating
of gas lines.
Bruest flameless, infrared, radiant heating
systems provide long service life with minimal
maintenance; many of our catalytic systems have
been in continuous service for more than two
decades without the need for overhaul or
major repair.  Ken Wilburn, VP Bruest,
and an expert on oil and gas
pipeline protection, has taught
Pipeline Management
for Cold Climates at
Robert Morris College,
Pittsburgh, PA.  Bruest catalytic heaters are approved by Factory
Mutual and by Canadian Standards Association for
Group D locations. Each is custom-manufactured
to the application.
