Exhaust Silencers for a Ship’s Generator Set

A look inside ISTIQ’s workshop as our team fabricates SS304 stainless steel exhaust silencers for a marine generator application.

This video highlights the construction, assembly and dye penetrant inspection of welded joints. All eight units in the first batch received acceptance in weld inspection.

Industrial Fan Noise Control – Phoenix Biorefinery Project

Industrial exhaust fans can be a significant source of plant noise, particularly when high airflow and high static pressure are involved.

For the Phoenix Biorefinery Project, ISTIQ Noise Control was engaged to provide an acoustic solution for a Hürner-Funken HF R 355-17 D (DS3) exhaust fan supplied through EnviPure Pte Ltd.

The fan operates at approximately 5,400 m³/h and 2,929 rpm, with a total pressure difference of 4,638 Pa. Manufacturer data indicates an overall fan sound power level of approximately 106 dB(A).

Rather than treating the fan itself, ISTIQ addressed the two primary airborne noise paths — the air intake and discharge.

Our solution incorporated a purpose-designed combination of duct silencing and circular silencing, selected according to the fan’s octave-band noise spectrum, airflow requirements and connection geometry.

The acoustic calculation predicted:

Discharge: approximately 96 dB(A) → 73 dB(A) at 1 m
Intake: approximately 96 dB(A) → 82 dB(A) at 1 m

The discharge silencer was designed to provide as much as 30 dB insertion loss at 2 kHz, while maintaining the airflow path required by the process fan. Exhaust Fan Sound Level Data.pdf

This project demonstrates an important principle in industrial noise control: effective fan noise reduction is not simply about adding a silencer. The silencer must be selected around the fan spectrum, airflow, pressure requirements and actual noise transmission path.

That is where acoustic engineering makes the difference.

6S Program – Teamwork in Action Day

A cleaner workplace starts with a stronger team.

Our team came together for a meaningful day of gotong-royong, embracing the 6S principles—Sort, Set in Order, Shine, Standardize, Sustain, and Safety—to create a safer, more organized, and efficient working environment.

At ISTIQ, continuous improvement goes beyond our engineering solutions. It reflects our commitment to quality, teamwork, workplace safety, and operational excellence in everything we do.

Thank you to everyone who contributed to making this initiative a success.

One Team. One Goal. One Transformation.

Another completed phase in our ongoing acoustic piping insulation work at YTL Cement Factory, Kanthan, Ipoh.

ISTIQ is proud to support YTL’s continuous noise reduction program throughout the factory, helping create a safer, quieter, and more comfortable working environment through proper insulation, aluminum cladding, and acoustic treatment works.

This latest phase covers the ITO Blower and K4 Klin Blower Axial, with insulation works, aluminum cladding installation, and intake silencer reinstatement completed as part of the overall noise control improvement program

From Roar to Whisper: The Resin Crusher Transformation 🔊➡️🤫

A Resin Crusher is a powerhouse in production, but the noise it generates can be overwhelming. Our latest installation at the Air-Cond factory facility (completed Dec 2025) proves that you don’t have to sacrifice a quiet environment for heavy-duty performance.

Watch the video to see how our ISTIQ Acoustic Enclosure tackles extreme noise, ensuring the factory floor remains a safe, compliant, and focused environment.

Is your machinery too loud? We have the solution.
