Bruest HotCat is the
Ultimate in Lean, Efficient
Pipeline Freeze Protection!

Advanced Pipeline Gas Heaters
Have No Moving Parts, are
Easy to Maintain

Bruest HotCat consists of multiple catalytic
infrared gas heaters that apply a precise level
of heat directly to the custom-engineered
heat exchanger.  Bruest heaters employ
greater surface area by doubling the pipe
diameter in the heat exchanger.  This
maximizes heat transfer while slowing the
flow of gas.  This results in highest-possible
retention time – and best-possible transfer
of heat energy to the gas.

Bruest HotCat is a stand-alone system that’s
custom-engineered to the application,
and self-contained: the pre-plumbed fuel gas
manifold that feeds the Bruest Catalytic gas
heaters is built into the unit, as are serpentine
or U-tubes.  Both are ASME stamped.

Quiet Operation:
No Firetube Noise

The dull roar of a firetube from a water
bath is commonly described by operators –
and neighbors – as resembling a freight train.

Bruest catalytic gas heaters are quiet;
regardless of operational mode, they are
noiseless, and highly preferable to water
baths for sites such as town border stations.

Pipeline Freeze Protection
with Maximum Efficiency

Water baths heat indirectly: the glycol-water
mix is heated, which heats the bundle ("coil")
which, in turn, heats the gas. The Bruest
HotCat provides direct infrared heating,
and delivers heat energy with maximum
efficiency to keep operation costs low.

Regarding maintenance, water baths
require annual heat bundle replacement –
and dumping of the glycol bath.

The only maintenance required for HotCat
is checking the filter and regulator.

Bruest catalytic infrared gas heaters are
engineered for long service life; many
of our catalytic systems have been in
continuous service in the natural gas
industry for more than two decades without
requiring overhaul or major repair.

Installation Flexibility

A water bath / firetube device requires 15’ of
clearance outside the Division 1 perimeter. 
Bruest HotCat gas heaters can be installed in
Class 1, Division 1 or 2, Group D areas
without restriction.

Remote Control
Saves Time, Labor

HotCat’s design allows real-time start-up and
control from your command center.  Systems are
engineered with 8 zones for greatest efficiency.

Facing a “Nor’easter?”  Perilous driving, and
plowing through snow banks is yesterday’s
problem.  With Bruest gas heaters, as demand
increases on the pipeline, operators can
respond immediately, directing the precise
amount of heat needed, precisely where it’s
needed.  And because the heat is direct,
pipeline heating is fast and efficient.  When
the demand changes, downward adjustments
are also made quickly, reducing energy
consumption, saving time, labor and dollars,
and improving overall safety.

The Bruest HotCat monitors gas inlet
temperature to provide positive, immediate
control of gas outlet temperatures, without
costly instrument configurations.

HotCat Environmental Gas
Heaters are Also Safer

Bruest HotCat does not have the cost,
or hazard, of water bath fire tubes, with their
open flame. They are suitable for Class 1,
Division 1 or 2, Group D applications.

Bruest gas heaters generate virtually no NOx
or VOCs – and have been honored by USEPA
with the agency’s prestigious Pollution
Prevention Award.

Because there are no fluids, stacks, or
containment rings, there are no water bath
maintenance issues from rust corrosion,
and no chemical odors.

The framing and exterior of the Bruest
HotCat are stainless steel and virtually
maintenance-free.  The gas heaters are
also stainless steel.

HotCat Gas Heaters are the
Most Efficient Technology
Available for Long-term
Freeze Protection of
Natural Gas Lines

The technology is also applicable for
the heating of:

• high pressure gas from wellheads
  and distribution stations

• natural gas at gate stations

• high pressure gas from oilfields

• viscous oils, in order to reduce
  pump pressures and improve
  pumping efficiencies

• light hydrocarbons
