Process Driven

You’ll be assigned a lead engineer who will take you through the ZOOK Engineer to Order (ZETO) process.


Our application engineers will meticulously document your specific requirements, constraints, timelines, and budget. We’ll share fundamental pressure relief knowledge, then collaboratively apply that wisdom towards potential solutions.


We’ll draw insight from previous projects and best practices, ensuring ideation considers our collective processes, procedures, and workflows.


Our team will design the best solution for your application. Any proposal can include detailed calculations, drawings, models, and estimates.

Data-Driven Test

Our prototype is thoroughly tested against agreed specifications and protocols. Detailed reporting is methodically kept and shared with you.


Final production, with communicated timelines commences. Shipments are carefully packed and include any required quality control and/or certification documentation.

Developed Partnership

As an ISO 9001 accredited company, continuous improvement is engrained in our culture. We strive to proactively ensure your satisfaction, collect feedback, and apply those learnings back into our process.
