| Continuous
Blowdown Valve |
|
Model
# |
Valve with
adjustable stage nozzle, sample valve, and electric actuator
for automatically controlled continuous blowdown. automatically
controlled continuous blowdown to reduce blowdown wastage with
a GESTRA conductivity electrode and the continuous blowdown controller.
the blowdown line is automatically closed on shutdown of the
boiler plant.
Especially suited for boilers operating without constant supervision
(TRD 604). |

Model
# |
For
the highest boiler safety, GESTRA developed the self monitoring
low level alarm system. This system consists of a self monitoring
single electrode and a redundant, self checking low level switch.
this system is world wide proven and accepted.
The conductivity sensing electrode LRG 16-40 consists of a TDS
(Total Dissolved Solids) monitoring electrode for conductivity
measurement, a temperature sensor for detecting the fluid temperature
and a fully integrated conductivity (TDS) transmitter
The probe works together with the LRR 1-40 controller.

|
Model
# |
The continuous
blowdown controller LRR 1-40 used in conjunction with the conductivity
sensing electrode LRG 16-40 constitutes a conductivity (TDS)
monitoring and control system. Electrical conductivity is used
to measure boiler water TDS (Total Dissolved Solids). |

Conductivity
Control
Unit
|
| Features
and Benefits |
|
|
- Two conductivity limits with
one switch point each: TDS high (MAX) alarm and TDS low (MIN)
alarm
- Three position control
within a predefined proportional band
- TDS level (conductivity)
monitored and maintained within a predefined control range
- Stand-by input
- 24 H purging pulse for
continuous boiler blowdown
- CANBus system protocol
