Envirotech Systems Limited products

Envirotech Systems Limited offers advanced acoustic enclosures designed to reduce noise emitted from machines while ensuring operator accessibility and ease of maintenance. These enclosures support noise reduction from STC 25 to 55 and incorporate features such as vibration isolation, chemical and dust resistance, as well as humidity and temperature control. The design includes considerations for visibility, maintenance access, and waste discharge. With a lighting level of 300 LUX and optional double-glazed windows, these enclosures can also include air vents with acoustic treatment and customizable panels for repair. Each enclosure is constructed with acoustically treated parts to minimize noise leakage, tailored to meet specific acoustic requirements at competitive prices, providing efficient solutions catered to diverse needs in machine management.

An Acoustic Enclosure is a soundproofing structure designed to contain and reduce noise from machinery or equipment. Made from materials like metal, wood, or composite panels, these enclosures absorb and block sound, ensuring a quieter environment. They are commonly used in industrial settings to minimise noise pollution from engines, generators, compressors and turbines. Acoustic enclosures also enhance worker safety by reducing exposure to harmful noise levels and comply with environmental noise regulations. The primary function of an acoustic enclosure in India is to prevent sound from escaping or entering the enclosed space. It is constructed with sound-absorbing materials and sound-blocking barriers to minimize sound transmission.

Envirotech Systems Limited specializes in the design and production of Anechoic Chambers built to meet international standards such as ISO 3744, ISO 3745, and ANSI S12.55. These chambers are engineered to provide complete sound insulation and are crucial for environments requiring the highest level of acoustic measurement accuracy. Envirotech employs high-grade materials, including anti-reflection foam and gussets, to create durable and highly absorbent chambers. Manufactured in India, these chambers can be customized to various sizes to accommodate specific research and development needs. The design elements of their chambers address sound absorption, floor vibration isolation, and silenced ventilation, ensuring an optimal quiet space for precision testing. This is particularly useful in sectors involving automotive, IT devices, and audio equipment where precise measurements are crucial. Including RF shielding options allows for a controlled environment that can also manage electromagnetic interference.

Envirotech Systems Limited's Acoustic Louvers are engineered to significantly reduce the noise emitted by cooling towers. These louvers are crafted using premium materials such as stainless steel, aluminum, and fiberglass, offering robustness and durability. Designed for optimal acoustic performance, they feature perforated splitter undersides ensuring enhanced sound absorption. Available in both single and double-banked versions, these panels combine functionality with the ability to maintain airflow while dampening noise. Additionally, the louvers are filled with non-combustible, inert materials to ensure weather and vermin resistance. Multiple finishes such as vinyl-coated steel, polyester powder paint, and mill finish aluminum cater to aesthetic as well as functional needs. By integrating weather stops to prevent rain or snow intrusion, these louvers optimize cooling efficiency, potentially reducing costs by up to 70% when used as part of ventilation systems. Envirotech's solutions ensure compliance with industry noise limits while maintaining system efficacy.

Envirotech Systems Limited designs and manufactures Air Intake and Discharge Silencers designed to suppress airborne noise generated by equipment with ventilators or blowers. These silencers are used in various applications, including noise reduction for gas turbines, large electric motors, generators, fans, blowers, cooling towers, and HVAC systems. They offer a noise reduction capability ranging from 10 dB(A) to 50 dB(A). The design of the silencer can be tailored to either rectangular or circular shapes and specific low-frequency noise control needs. These units also feature inlet and outlet silencers incorporating FD fans and ID fans for two-way noise control performance, and they support noise suppression with heat recovery. The units are renowned for their high reliability and low total cost of ownership. Envirotech Systems also provides accessories for the silencers such as intake filters, mounting supports for vertical and horizontal installation, and flex connectors, ensuring versatility in integration and operational efficiency.
