Pressure Control with VAV Diffusers
Consider various pressure control methods in a VAV system. All diffusers become noisier with higher pressures at their inlet, which is true for VAV diffusers. Pressure is often reduced using a balancing damper or terminal unit, but VAV diffusers are unique as they have a built-in VAV damper that can close down to a minimum […]
Zone Register Terminals (ZRT®’s)
Zone Register Terminals (ZRT®’s) introduces flexibility and demand control to central ventilation systems. The multi-zone ZRT regulates ventilation without the need for individual fans. Combining a grille, register box, control damper and optional flow regulator provides up to four different control schemes without the need for expensive pneumatic, electronic, or DDC control systems. When used […]
Thermal Buffer Storage Tanks
Thermal Buffer Storage Tanks are used to store large volumes of chilled or hot water. They reduce chiller or boiler short cycling by increasing system capacity and stabilising the return water temperature. ecoHVAC have a wide range of Thermal Buffer Storage Tanks sizes from 500 – 15,000 litre and are available in both Mild Steel […]

High Performance Air Systems for Improved Comfort, Energy Efficiency, IAQ
In today’s built environments, HVAC systems are expected to do more than simply heat or cool a space. They must deliver comfort, maintain healthy indoor air quality (IAQ), and do so with a strong focus on energy efficiency. At ecoHVAC, we specialise in engineered air systems that meet these demands head-on — offering smart, high-performance […]
Energy Savings in Buildings – HVAC Best Practice
HVAC systems are among the largest energy consumers in commercial and institutional buildings. Implementing best-practice HVAC strategies not only lowers running costs but also enhances comfort, compliance, and long-term sustainability. At ecoHVAC, we help clients reduce energy use through smart, engineered solutions that support better building performance. Key HVAC Practices for Energy Efficiency Whether you’re […]
A Closer Look at the SteriTouch® Antimicrobial Coating on Apreco VARI-centric® Air Pressure Stabilisers
In critical environments like hospitals and isolation rooms, hygiene and infection control are paramount. That’s why Apreco’s VARI-centric® air pressure stabilisers, supplied exclusively by ecoHVAC in Australia and New Zealand, feature the added protection of SteriTouch® antimicrobial coating. What is SteriTouch®? SteriTouch® is a silver ion-based antimicrobial additive that actively reduces the growth of bacteria, […]
Induction in Chilled Beams and Diffusers
In high-performance HVAC design, induction plays a vital role in improving comfort, air distribution, and energy efficiency- particularly in systems using chilled beams and diffusers. What Is Induction? Induction refers to the process where supply air from a chilled beam or diffuser draws in room air, mixing it efficiently to maintain even temperatures and improve […]
Adjustable Constant Airflow Regulators
Adjustable Constant Airflow Regulators (CAR’s) are modulating device that automatically regulate airflows in duct systems to constant levels, Exhaust or Supply Air. The passive control element responds to duct pressure and requires no electric or pneumatic sensors or controls. The CAR unit compensates for changes in duct pressure caused by thermal stack effect, building pressure, […]
Installing a Drying Room Could Save Your Building
Protect Your Environment Even when you cannot see it, moisture in the form of water vapour is all around us, held in suspension in the air. The relative humidity of the air, in many cases determines the extent of corrosion of certain materials, the speed at which moulds develop and the rate of increase in […]
