Comfort and energy efficiency

There is a growing need for products that help create comfortable indoor spaces while maintaining a healthy and productive working environment. At the same time, new government policies and the dramatic increase in energy costs have created greater demand for products and systems that utilize energy efficient technologies. These new demands are now being driven by architects, engineers and developers to create buildings that offer both the optimal working conditions while saving energy consumption and reducing greenhouse gas emissions.

The RICKARD range of Variable Air Volume (VAV) diffusers helps meet these demands and is a cost effective system that is simple to operate and very reliable.

A highly effective design

Rickard VAV diffusers have a number of unique attributes that ensure they provide optimum performance over a long period of time. The diffusers feature a modern “flush” to ceiling/wall stylish look and aerodynamically shaped components that minimise noise while improving air flow characteristics.

All Rickard VAV diffusers are finished in a chip resistant baked acrylic paint which comes white as standard, but can be ordered in a wide range of colours. Rickard diffusers do not require routine maintenance, but in-case a repair is required, all mechanical components are easily accessible from inside the room. As a result any maintenance is simple, low cost and can be carried out with minimal disruption to the room occupants.

Comfort and productivity

Rickard VAV diffusers help to provide a well ventilated indoor environment that maintains a consistent and comfortable temperature in most types of applications. They eliminate the negative impact undesirable thermal conditions can have on output, accuracy and productivity.

Rickard diffusers achieve this by allowing only the required amount of conditioned air to enter the space. This air volume is determined by the temperature in the space and the set-point on the diffuser’s in-built temperature sensor or wall thermostat. The set-point on individual diffusers can be easily adjusted by the occupant, giving them total control over their environment during any part of the day.

Rickard VAV diffusers provide excellent supply air distribution, which ensures uncomfortable drafts, or air dumping are minimised. Air is discharged from the square diffuser in a 360 degree pattern and circulated around the room and up through the centre to ensure the air within the space is thoroughly mixed and the space is kept at the desired temperature.

Simple & energy saving solution

A key benefit of Rickard VAV diffusers is their ability to potentially reduce the energy consumption of a building by reducing the demand on the air handling system. They achieve this by allowing only the required volume of hot or cold air to enter the conditioned space according to the set point. If the required air volume reduces, the diffuser’s aperture size also reduces which creates additional pressure in the ductwork. This pressure signals to the air conditioning system to slow down which in turn saves fan energy. If the air volume required increases, the diffuser’s aperture opens allowing more conditioned air to enter the space.

The incentive for building owners and tenants to have energy efficient rental spaces has never been higher. Rickard VAV diffusers can also help achieve Green Building Credits for Building Management, Indoor Environmental Quality and Energy Efficiency.

Rickard VAV diffusers are easy to install and set up, and will function effectively when the building’s air conditioning systems are in either cooling or heating mode. All Rickard ceiling diffusers are either installed in suspended tiled ceilings with “T” frames or standard plaster board using a standard ceiling frame.

Rickard VAV diffusers are available as:

System controlled, electronically
powered models.

Standalone, mechanically
controlled models

Each VAV diffuser model is available in various configurations which are suitable for numerous applications or mounting positions. The range comes in square, linear slot and bulkhead models.
