CENTURION
- Gas & Oil Fired Cabinet Heaters The Ambi-Rad free standing range of cabinet warm air heaters combine innovative design techniques and proven heat exchanger technology, to produce units that are cost effective, efficient and aesthetically pleasing.
A range of model sizes cover heat outputs from 30kW to 279kW
FEATURES
| • | Natural gas, propane or oil fired | |
| • | Four pass heat transfer for improved thermal efficiency. | |
| • | Combustion chamber/heat exchanger assembly is flexibly mounted to allow for thermal expansion | |
| • | Double skin pentapost construction incorporating air cooled heat shield. | |
| • | Freeblowing or ducted air distribution. | |
| • | Choice of free standing vertical or horizontal units. |
SPECIFICATION
Heat Exchanger Construction
The combustion chamber, manufactured from high quality heat resistant stainless steel, has a large surface area and volume to avoid localised hot spots, ensuring long life. A tubular cross flow heat exchanger provides excellent fuel economy and the heat exchanger tubes are expanded into the collection boxes, thereby eliminating the possibility of weld failure.
The complete assembly is mounted to allow for expansion, counteracting the effect of thermal stress.
Air
Handling
Double inlet high efficiency centrifugal fans circulate air across all the heated surfaces to give low surface temperatures and maximise efficiency. Fans on models 100 to 300 (standard efficiency) and 30 to 75 (high efficiency) are direct driven using a single phase motor. All other models are driven by a heavy duty three phase motor and v-belt system. Air discharge is via a nozzle outlets or a four way louvred head. Alternatively units may be installed with a fully ducted distribution system.
Cabinets
The
cabinets are constructed using a full pentapost frame and panels with
an inner galvanised steel skin. All panels are easily removed for servicing.
Units are finished in a durable two tone powder paint. Four mounting feet are incorporated into the cabinet, to ease on site handling. After location, these feet may be removed or left in position to raise the air inlet away from the floor to minimise ingress of dust. Horizontal cabinets are supplied with six mounting feet for plant room applications.
Fuel
Heaters are available to operate on either natural gas (G20), propane (G31, 28 or 35 sec oil. See technical data table for availability.
Gas fired units are fitted with a fully automatic forced draught burner complete with full safety controls. The heaters are tested and approved to the relevant CE standards.
Oil fired models are supplied complete with a fully automatic forced draught pressure jet oil burner complete with safety controls and matched to each heater for optimum flame shape and efficiency.
Controls
A combined fan and limit thermostat is fitted on all heaters which delays fan start until the heat exchanger has reached operating temperature and continues to run the fan after the burner switches off until after the burner switches off and the remaining heat is dissipated. In the event of overheating, the unit would automatically be shut down by the limit thermostat.
On vertical models an electronic time and temperature controller may be either pre-wired to the heater or supplied as a remote panel. Horizontal models are supplied with remote panels.
