Extraction Booth PLC & Controls

Extraction booth control systems manage critical safety functions: gas sensor interlocks, ventilation automation, emergency shutdown sequences, and fire suppression integration. When controls fail, safety fails. WERCS diagnoses at the component level - tracing faults from the gas sensor through the PLC interlock chain to the fan motor relay.

Problems We Solve

WERCS technicians are experts at diagnosing and fixing extraction booth issues that cost you time and money.

Sensor-to-PLC Communication Faults

Gas sensors must communicate alarm states to the PLC for interlock activation. Communication faults prevent proper safety response.

Relay Failures

Relays in purge circuits and emergency stop chains can fail open or welded closed. Either failure mode compromises safety.

Emergency Stop Degradation

E-stop circuits must function when needed. Contact degradation, wiring faults, and relay failures can prevent proper shutdown.

No Manufacturer Support

ExtractionTek recently closed - leaving their entire installed base with zero technical support. WERCS services these systems and others.

Our Service Process

How WERCS delivers exceptional results every time

Control System Analysis

We document control system architecture: PLC model, I/O configuration, sensor connections, interlock logic, and communication protocols.

Diagnostic Testing

We test each element of the safety interlock chain - from sensor output through PLC logic to actuator response - identifying faults at the component level.

Repair & Verification

We repair or replace failed components and verify proper operation of the complete interlock sequence.

Documentation

We document all control system conditions, repairs performed, and verification test results.

Extraction Booth PLC & Controls FAQ

Common questions about our services

The control system manages: gas sensor monitoring and interlock activation, ventilation automation (base rate to purge rate transition), emergency shutdown sequences, fire suppression system integration, and door interlocks. It is the brain of the safety system.

If gas detection does not properly trigger ventilation purge, flammable vapor can accumulate to explosive concentrations. This is the scenario that causes extraction lab explosions. Proper interlock function is life-safety critical.

Yes. WERCS services ExtractionTek (ETS) control systems including their proprietary automation. With ExtractionTek now closed, we are one of the few service providers with expertise on their installed base.

WERCS designs and implements control system upgrades for extraction booths with obsolete or unsupported components. We can migrate from discontinued PLCs, replace failed HMIs, and modernize safety interlock systems while maintaining compliance.
