FLAT HEATERS - CAST ALU/BRASS HEATERS

 

Cast Flat Heaters

Cast Aluminium and Cast Bronze heaters offer optimum heat transfer directly to the contact surface.

These heaters are usually custom designed in house using state of the art cad ware alongside many years experience to obtain maximum heater life.

Every shape and size can be manufactured in our modern patternshop and foundry, before being fully machined in our machine shop prior to termination at final assembly.

There are many terminations available from metric to American threads, high temperature leads to high temperature plug and socket arrangements.



Recommended Limits
Watt density:
Cast Aluminium 4.7 W/cm²
Cast Bronze 7 W/cm²
Temperature:
Cast Aluminium 400°C
Cast Bronze 650°C


Installation Recommendations
・Surface to be heated must be clean from contamination, smooth and compatible to the machined surface of the heater.
・Water fittings must be free from leaks, threaded connectors are the most common way of ensuring this.
・After initial warm up to operating temperature, the heaters should be isolated from the electricity supply and re-tightened to compensate for thermal expansion.
・All connections should be made with suitable high temperature wiring. Terminal enclosures can be provided up to IP65 for ease of wiring and operator safety. All units must be adequately earthed.


Maintenance
・Heaters must be disconnected from supply before any maintenance is carried out.
Electrical connections should be periodically checked to prevent arcing which could damage the heater terminals
・Heater clamping arrangements should be checked regularly and re-tightened when required.
