AN AUTOMATIC photocell-type shut-down device is a feature of three of the four Hecta paraffin-burning mobile blower heaters offered by Landmaster, the Standard model being the only one without this feature. The device switches off the heater in the event of a fuel or power' failure and a kit is available to convert a Standard machine to the Super specification. Fuel costs are said to be around 5p /hr.
The smallest models, the Hecta 105 Standard and Super heaters, have an output of 105,000 Btu /hr and produce 500 Cu ft of warm air per minute to heat up to 30,000 cu ft of space. Ducting and other ancillaries are available.
Having an output of 112,000 Btu /hr, the Hecta 150CA heater produces 1000 cu ft of warm clean air per minute, while the Hecta 300 CA has outputs of 220,000 Btu /hr and 2000 cu ft/min. The 150CA amd 300CA are vented to enable a flue to be fitted for the removal of fumes to the outside of the building being heated. These models are therefore, particularly suitable for poultry houses and other livestock buildings and for buildings used for drying in which clean air is particularly required.
The fan drives cold air over and through the combustion chamber and mixes with the hot combustion gases at the nose cone and baffle. Before the fuel is supplied to the atomizing nozzle it is pressurized to 100 psi.
