Optima

  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.


OPTIMA BENEFITS

  SE typically saves an additional 30% on fuel costs over standard radiant tubes
  Specifically designed for industrial or commercial buildings
  Creates no draughts on air movement, so increasing work force comfort
  Does not re-circulate dust and airborne contaminants
  Rapid heating up and recovery times
  Systems can be zoned to accommodate varying temperatures and opening times
  Heaters mounted at high level release valuable floor space
  Can be integrated with energy management systems
  Minimises roof heat losses
  Fuel burnt where and when heat is required, eliminating distribution and standby losses
  Easy to install and service
  Environmentally friendly, with reduced emission levels
  Minimises maintenance
  Design Flexibility - through innovative styling


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.
