MODEL OPTIONS
All units incorporate a high efficiency Thermocore Heat Exchanger, plus alternative air handling systems.

AXIAL FAN TA and STA units are fitted with high quality axial fans to provide excellent air distribution at low noise levels, for freeblowing applications.
CENTRIFUGAL FAN TB and STB units are fitted with belt drive centrifugal blowers for increased air flows and mounting heights, or for ducted installations with static pressures up to 400Pa.
ENCLOSED FAN TE and STE units are fitted with a fan enclosure cabinet and belt drive centrifugal blowers. The fan enclosure cabinet and belt drive centrifugal blowers. The fan enclosure allows the use of return air ducts, filters and fresh air intakes. Full size access doors are fitted to both sides of the fan cabinet for ease of service access.
MIXING BOX TE and STE units may also be fitted with a mixing box type fan enclosure cabinet. The fan enclosure cabinet can be fitted with either a single fresh air damper or interlinked fresh and return air dampers. The dampers may be either manually controlled or fitted with two position or fully modulating damper actuators. Optional filters fitted internally within the cabinet provide filtration to both the fresh air and recirculation air.

DESTRATIFICATION
An optional destratification system may be added to heaters mounted at high level to recirculate stratified warm air back down to working level, even when the burners are switched off. A temperature sensor monitors the high level air temperature and operates the heater fan independently of the burner.
