ARENA SPECTATOR 'COMFORT' HEATING
Contact Schwank Design for Arena Heating: Fax 1-866-724-9265; [email protected]
In community arenas, infrared spot heating is the most effective solution for spectator areas. Desired 'comfort' results
directly from the contact of infrared radiant heat produced by an IR heating system.
In designing an arena spectator heating system, it is necessary to remember that "heat" in an ice-making facility is somewhat counter
productive to the efforts of facility staff to produce and maintain both the ice and the facility structure.
Any convection heat produced by the IR system is detrimental to arena facility ice-making operations. The moisture in the
products of combustion and higher humidity due to warmer air in the structure can have a negative impact on the structure by
condensing on the cold interior surfaces of the building.
NOTE: Schwank does not recommend the use of tube heaters as an effective arena spectator heating solution. Tube heaters have
lower radiant intensity and less focus or direction of the infrared heat output. However, tube heaters are often specified.
Typical High Intensity 35% to 40%
Good ecoSchwank Up to 50%
Better primoSchwank Up to 67%
Best supraSchwank Up to 81%

*** Schwank infrared efficiency test data from CSA International and other test agencies available upon request.
An independent test agency reported tube heater radiant efficiencies from 33% to 44% with steel tube heat exchangers.

The optimum arena heating design must not only provide spectator comfort, but must also reduce the concerns of the arena staff regarding
arena operation. Schwank luminous heaters meet and exceed these requirements:
