Proctor Ventient Trickle Ventilation

Proctor Ventient EcoSmart Breathe 

Product Description

Using passive temperature perception technology, Proctor Ventient™ EcoSmart Breathe in utilizing the physical characteristics of a unique Shape Memory Alloy (SMA) does not require the use of electric power or sensors.

Without electric power, sensors or human intervention, Ventient Trickle Ventilation technology can passively manage ventilation flow dependent on ambient temperatures, optimising the benefits of ventilation without introducing air at an uncomfortable temperature. 

Applications

Unlike conventional systems such as operable windows or louvres, Proctor Ventient can get on with the job of providing fresh air circulation regardless of occupancy.

As part of the total ventilation system Proctor Ventient can help reduce the need for cooling in buildings and provides fresh air for educational and healthcare facilities.

Providing ventilation for rooms or spaces that can remain unoccupied for periods throughout the year. Perfect for student accommodation and hotels.

Modern lifestyles mean that occupants are unable to manage purge ventilation and return home in the evening or after a few days away to stuffy environment. Ventient is an ideal solution for residential buildings such as modern air tight medium and high rise developments.

Natural Ventilation

Ventient devices (although unlikely alone) can contribute towards the total openable size of not less than 5% of the floor area of the room required to be ventilated.

Exhaust Make-up in Lieu of Supply 

It is not possible to meet the code requirement for natural ventilation, when assessing for greenstar, or where the design preference is for a specific air change rate and 24 hour provision of fresh air without leaving windows open, Ventient used in conjunction with low energy, mechanical extract ventilation can provide or contribute to supply ventilation as required when calculated in accordance with AS1668.2.

General Exhaust Make-Up Air

AS 1668.2 draws to the attention of designers that increased air-tightness of modern buildings requires consideration of  sources of make-up air.

In the past there has been a reliance on leakage through historically poor facade construction.  Make-up air drawn through gaps and service penetrations does not meet the requirements of Clause 2.3 within the standard and concerns related to make-up air being drawn through poorly sealed construction joints, brick cavity vents and even power outlets can lead to the loss of amenity in the enclosure.

Clause 2.3 specifies acceptable sources of outdoor air as a mechanical outdoor air supply or permanent natural ventilation openings. Ventient can  provide the later option.
