BosB systems for boilers - operation without constant supervision
For decades, astebo has relied on a unique BosB system, which reliably and physically checks all limiters in the boiler system on a regular basis. The perfect functionality of the boiler safety equipment can thus be proven at any time.
Operation without constant supervision
For decades, astebo has relied on a unique BOSB system, which reliably and physically checks all limiters in the boiler system on a regular basis. The perfect functionality of the boiler safety equipment can thus be proven at any time. The term BOSB stands for “operation without constant supervision”. This is a device for monitoring the boiler and for boiler house security. Some of the limiters for monitoring the operating parameters of the boiler are tested during operation, WITHOUT putting the burner out of operation. This is only switched off after 720 hours or after every tenth test, provided that no regular shutdown has taken place in the meantime. The standard check must be carried out cyclically at least every 72 hours. If a test is completed positively, the running time starts again with 72h from the beginning.
One of astebo's specialties is the retrofitting of existing steam boiler systems to state-of-the-art BOSB systems, whereby we use our special knowledge of boiler construction and process engineering for the benefit of our customers. If you decide in favor of a new BOSB, a boiler control can be expanded cost-effectively thanks to the modular structure with little additional effort.

100% conformity. 100% astebo.
The physical test of the limiters without taking the boiler out of operation is the real proof of the functionality of the boiler's safety devices. I.e. With this type of BOSB there is no loss of production due to e.g. Low water setting, filling and restart of the boiler system in the course of the inspection.
Our BOSB also enables the operator to monitor the system in live mode in real time. Faults are shown as fault messages in plain text. This creates real added value in troubleshooting and troubleshooting in the form of this extended diagnostic function shown directly via the graphical interface.
