Hydraulic pump test benches are notoriously loud. Between the pump motor, oil flow, and pressure cycling, decibel levels on an open bench can climb well past what’s safe or comfortable for nearby staff. That was exactly the challenge U3S Engitech Private Limited, based in Cuttack, Odisha, brought to Ecotone Systems — and the result is a newly commissioned insulated acoustic enclosure built specifically around their hydraulic pump test bench.
U3S Engitech needed more than a basic sound cover. Their test bench runs extended duty cycles, so the enclosure had to handle sustained heat buildup, vibration, and continuous mechanical noise without degrading over time. Ecotone Systems engineered the acoustic enclosure with a layered composite panel structure — a perforated inner skin, high-density mineral wool insulation, and a solid outer shell — designed to absorb noise at the source rather than just muffling it.
Getting this right matters. A poorly designed enclosure traps heat, which shortens pump life and skews test readings. Ecotone Systems built forced ventilation and cooling provisions directly into the acoustic enclosure, so the hydraulic pump stays within safe operating temperature even during long test runs. This is a detail a lot of manufacturers overlook: an enclosure that solves noise but creates a heat problem isn’t really solving anything.
Access was another priority for U3S Engitech. Technicians need to reach the pump, hoses, gauges, and fittings quickly during setup, testing, and maintenance. So the acoustic enclosure includes hinged access doors and viewing panels, letting operators monitor the test bench visually without opening the unit and losing the acoustic seal. Cable and hose entry points were sealed with acoustic grommets to prevent sound leakage at every junction — because even a small gap can undo a lot of the insulation work.
On performance, the enclosure was built to bring noise levels down to within safe industrial exposure limits, protecting workers on the shop floor from prolonged exposure to pump noise. That’s the real point of an acoustic enclosure in a test environment: it’s not just about compliance paperwork, it’s about people being able to work near the bench for a full shift without hearing damage or fatigue.
This project adds to a growing list of test bench and equipment enclosures Ecotone Systems has delivered across India’s industrial and engineering sectors. From hydraulic and pneumatic test rigs to engine dyno cells and turbine enclosures, the underlying engineering challenge is similar — control noise, manage heat, and keep the equipment fully accessible for testing and servicing. Ecotone Systems approaches each one as a custom build rather than a catalog product, which is part of why manufacturers like U3S Engitech keep coming back with new requirements.
For companies running hydraulic test benches, pump stations, or similar high-noise equipment, an insulated acoustic enclosure isn’t an optional add-on anymore — it’s becoming standard practice for safety compliance and workplace noise regulations. Ecotone Systems designs and fabricates these enclosures to match the exact dimensions, access needs, and duty cycle of the equipment they house, rather than forcing a one-size-fits-all box onto a test setup.
With the U3S Engitech project now complete and commissioned in Cuttack, Ecotone Systems continues to expand its footprint in Odisha’s industrial manufacturing base, delivering acoustic solutions built for real-world test bench conditions rather than just spec sheets.
