Self-checking high level safety kit
This system ensures that the level in the boiler does not exceed the allowed value thus avoiding flood problems.
It consists of a "fail safe" probe connected to an electronic level relay with self-checking feature, capable of indicating:
–
the presence of water above the set level
–
the lack of insulation inside the probe
–
faults inside the device (self-check)
–
interruption of the connection between the probe and the device in compliance with EN 12953-9 point 5.4.8.
When it trips, the system triggers a visual and an acoustic alarm and stops the feed pump temporarily.
The alarm is reset automatically once the level is again below the allowed maximum value.
The system is supplied completely assembled to the boiler and tested. It complies with the main European Directives:
–
Low Voltage Directive 2014/35/EU.
Self-checking low level safety kit
This system, supplied as an alternative to the standard low level probes, is designed to ensure that the level in the boiler does not
go below the allowed value.
It consists of two independent "fail safe" probes connected to two separated electronic level relays with self-checking feature,
capable of indicating:
–
the lack of water below the set level
–
the lack of insulation inside the probe
–
faults inside the device (self-check)
–
interruption of the connection between the probe and the device in compliance with EN 12953-9 point 5.4.8.
When it trips, the system triggers a visual and an acoustic alarm and stops the boiler permanently.
The boiler operation is resumed only after the manual reset and the elimination of the error by the operator.
The system is supplied completely assembled to the boiler and tested. It complies with the main European Directives:
–
Low Voltage Directive 2014/35/EU
–
EMC Directive 2014/30/EU
–
PED Directive 2014/68/EU.
Modulating level regulation system with 2-way electric valve
With this system, the level in the boiler is adjusted continuously by a PID controller that controls the opening of a modulating
valve placed downstream the feed pump kept always running.
The water flow rate is constantly adjusted to steam request, thus avoiding the cyclical steam production that can be checked with
level controls of the on/off type.
By ensuring a continuous water delivery flow towards the boiler, the use of the modulating feed is mandatory with the economiser,
in order to ensure its correct operation.
Economiser ECXV model
Economiser for the recovery of exhaust gas heat to pre-heat the water delivery; supplied fitted and connected vertically to the
boiler and complete with accessories.
Spare feed pump (for steam generators)
In order to ensure continuous operation of the generator, avoiding production stops in case of feed pump failure, a second spare
pump is installed in parallel to the service pump.
Cooler for sampling
To make sure that the generator is working within the desired conductivity parameters, take water samples and analyse them.
To safely obtain accurate samples, it is essential to perform adequate cooling in order to condensate any fresh steam before the
sampling point. The cooler reduces the water temperature to 25°C, ready for immediate sampling.
