Silencers for Marine/Offshore

Silencers for Marine and Offshore Applications

Silencers are used to reduce the noise in “air moving” applications such as air conditioning or ventilation systems, fan  inlets and outlets, enclosure ventilation and other applications.

Silencers are insulated with acoustic infill and an optional central-pod can be inserted in the silencers for higher attenuation. For marine and offshore applications, the  silencers are made in a heavier construction to suit the application.

A manual control single flap damper can be built-in upon request.

Hison Plated Mounted Fans

Introduction

• Hison Axial Flow Fans, formerly know as Howden Fans are manufactured to International Quality Standard.
• Available from sizes 150mm to 1250mm diameter.
• Incorporate heavy duty marine grade LM-6 or equal cast aluminium impellers with aerofoil blades for better efficiencies and lower sound level.
• Adjustable blades angles designs to meet varied volume and pressure system requirements featuring the blade shank with tapered conical section. The tapered section fits into a conical slot in the hub, providing a taper lock fit. A bolt is cast into the blade, projecting into the hub and is secured on the inside by lock-washer and nut.
• Hison Impellers comes in polypropylene and aluminum.

Performance

• Ranges from 100m³/hr to 250000m³/hr and static pressure up to 125mm.
• Performance of Hison Fans are tested in accordance to BS 848 Part 1 1980, the latest ISO 5801 First Edition 1997-06-1 and many of Hison Axial Fan models are also tested in accordance to AMCA 210-99 Standard for air performance and licensed to bear the AMCA seal.
• Sound level data is in accordance with BS 848 – 1985: part 2. and ISO 5136 First Edition 1990-12-15.
