The Hi-Velocity mini duct system
Mini duct systems are well suited for industrial, commercial, retail and residential markets. The huge range of applications includes houses, offices, factories, hotels, restaurants, server rooms, care homes, schools, pubs and clubs, laboratories, leisure centres, hospitals and art studios. Manufactured in Canada since 1983, tens of thousands Hi-Velocity mini duct systems have been installed worldwide.

The Hi-Velocity mini duct system provides a comfortable environment, free from draughts and hot and cold spots, by using Bernouli’s Theorem and the Venturi effect.

The Hi-Velocity system uses a modular air handler connected to 200mm or 250mm diameter ductwork plenum, plus insulation. A number of patented flexible mini ducts, which terminate in small air outlets, are connected to this plenum. The plenum is available in standard spiral, rectangular metal duct or lightweight phenolic foam duct. The phenolic foam duct has excellent thermal properties and external and internal foil lining.

The vents are discrete and can be mounted in the ceiling, floor or walls. Each is equally effective. Outlets can be made in many styles and finishes to perfectly match any decor, theme, design or layout you choose.

Ductwork design and air handler positioning are made easier by the particular way the system operates. Cooling & Heating Sales Ltd are happy to assist with design and plotting duct rows.

A high efficiency inverter fan motor creates a static pressure in the plenum ducts (approx. 325 pa). This static pressure (potential energy) is converted to velocity pressure (kinetic energy) at the vent outlet. Here, Bernouli’s Theorem and the Venturi effect distribute the heating and cooling throughout the conditioned space without further taxing the fan motor. This increases the efficiency of the system.

The Hi Velocity system can be paired with inverter heat pump condensing units, chilled water systems and hot water sources including boilers, ground source heat pumps and solar panels.

Each air handler can have a maximum of eight control zones, with individual time and temperature settings in each area. In this way the quantity of indoor units required on large projects is reduced, thus further increasing the environmental benefits of the system.

The system has options for heating, cooling, fresh air ventilation (up to 100%), air filtration, connection to a heat recovery unit, dehumidification and ultraviolet air cleaning. It provides one of the most comfortable environments possible - even temperatures, without draughts or breezes. It eliminates the need for traditional radiators or under floor heating systems.
