SYSTEM APPLICATION
The Optima series is ideally suited for industrial and commercial premises, whether they are new low-energy structures, or old poorly insulated buildings. In environments with high air-change, or where there is a need for controllable heat, the system's high efficiency will greatly reduce running costs and improve capital payback.
Optima is available in a 'U'-Tube configuration only and may be flued into a central manifold to create a multi-burner single exhaust system. Heaters are suspended horizontally or can be angle-mounted to a recommended maximum of 30°.
The improved appearance of the Optima SE widens the use of radiant heaters bringing the benefits of energy saving to building types that were previously precluded because of the styling limitations attributed to other radiant tube heaters.

INCREASED RADIANT EFFICIENCY
Radiant efficiency is defined as the amount of usable radiant energy from the combustion process that is emitted downwards to the floor. Measured in accordance with the latest European pre-standard (DD ENV 1259-1:1994), the Optima SE achieves a radiant efficiency of up to 76%. This represents a 30% increase in efficiency over any competitive standard radiant tube system currently in the market place.
This advance has been achieved primarily through the combination of new burner technology and the incorporation of insulated black emitters, optimised tube geometry, insulated overshield reflectors and endcaps. (Patent No. 2292214)
This increase in radiant efficiency provides the flexibility to the customer of reducing the input of gas by up to 30% (over standard radiant tube heaters), whilst maintaining the required comfort condition in the building. Thus, significant fuel cost savings can be achieved.
