The SP series of gas burners are pre-packaged, fan assisted units designed to fire applications where fresh air is to be heated from ambient temperatures up to plant requirements. The SP can be fitted into air ducts having velocities of 5-30m/sec.

The units consist of an 'in-line PH' type combustion head mounted on a side plate so as to fire parallel to the side plate in direction of air flow. The burners are avilable in 'straight', 'T' and 'X' sections which enable the burner to be constructed to suit the appliance layout.

All air required for combustion is supplied by an integral combustion air fan mounted on the burner head and situated inside the process air duct. Air temperatures up to 40°C can be accepted upstream of the burner. Downstream temperatures of up to 400°C can be accommodated.

The burner systems produce a wide flame spread and a short flame; this feature means the burner is ideal for applications where chamber length is restricted and even heat distribution is required.

The SP burner is simple and safe to operate. All burners are prefired and fully tested before leaving our works.
