STAB-IN (on a plate)
Duct Insertion Heaters
KALORIC Stab-in (on a plate) Duct Insertion Heaters
are designed for insertion in a rectangular opening cut in the side
of an air duct. The elements are fitted to a galvanised sheet steel
plate which can be screwed on to the duct by means of self-tapping
screws or similar fixing arrangement. A removable cover box protects
the terminals of the elements and the manual reset thermal cut-out.
The Insertion Units are supplied as a standard fitted with a manual
reset thermal cut-out for protection against overheating. They are
also available with Auto and Probe cut-outs, which can be supplied
fitted with a third terminal suitable for connection to light and
sound alarm if required. The standard disc type single phase cut-out
has a carrying capacity of 15 amps at 240 volts.
Loadings exceeding the above have to be wired in the coil circuit
of a contactor. In case of 3 phase supply, the cut-out has to be
connected in line with the single phase coil of a 3 phase contactor.
Duct insertion heaters are a particularly simple and economical
method of providing additional heat for boosting or similar requirements
where existing ducting or plants are to be utilised. The elements
are available in a wide variety and are tailor made to suit operating
conditions and individual requirements.
When installed, Insertion Units should be supported so that their
weight is not transmitted to ductwork and so they can be easily
removed for cleaning or renewal purposes without disturbing the
adjacent ductwork.
In addition to duct insertion heaters KALORIC can supply heaters
suitable for installation in air handling and air conditioning units
of many manufacturers.
When ordering, state duct size, total load, number of steps, voltage,
phase, air volume, entering and final air temperatures.
These appliances must be earthed and be wired and fitted to
comply with the latest I.E.E. Regulations.
