|
| Cobra
represents a radical new approach to gas fired radiant heating
a packaged heater that requires no on site assembly. |
| |
| It
can simply be unpacked and suspended into the roof space dramatically
reducing on site handling and installation time. |

Specification |
| |
|
|
| |
|
Cobra
incorporates a 20kW gas fired burner suitable for natural gas (G20) and
propane (G31). |
| |
|
The
Cobra is currently available in two sizes and is constructed from twin wall
steel panels. Units can be installed unflued, individually flued, or on
a central herringbone manifold and can be fitted with ducted
fresh air intake onto the burner to provide combustion air from outside
the building. |
| |
|
Cobra
is very quiet in operation being rated at 40 and 48dB(A) for the 20 and
40kW models.
The noise levels can be further reduced by up to 6dB(A) by flueing the product
and filling ducted fresh air. |
| |
|
Cobra
is despatched in shrink-wrapped packaging which can be left on when installed
to protect the heater from soiling during other non-related building work.
The packaging then can simply be removed when the unit is commissioned. |
| |
|
Cobra
tube specification is of stainless and aluminised high temperature steel
for improved longevity and performance. |
| |
|
Protective
ball guards and decorative grilles are available for applications in sports
environments. |
