ecoHVAC are distributors of the Aquasystem Expansion Tanks.
Vertical Expansion Tanks with Replaceable Bladder:
All our tanks are supplied with the EXPAK, or fill kit, which incorporates automatic fill valve isolating valve, pressure relief valve and automatic air vent, all pre-assembled on a brass air separator.
Ex Stock Melbourne – 8 litres to 600 litres with smaller sizes also available in the flat (pancake) version (7; 8; 12lt only).
The main purpose of an Aquasystem expansion tank is to compensate the variation of the volume of water due to the variation of temperature in chilled or heating systems. e.g. Water heating up from 0⁰C to 100⁰C increases its volume of about 4.5%. This means that there should be space inside the system that can keep the exceeding volume of water. This space is the expansion tank.
The EXPAK, or fill kit, is also available for our tanks which incorporates automatic fill valve isolating valve, pressure relief valve and automatic air vent, all pre-assembled on a brass air separator.

DuctSox recommended a custom KitchenSox system to disperse the airflow uniformly, parallel and in front of the kitchen exhaust hood. The metal diffusers were replaced with two eight-foot-long (2.44m), 28-inch-diameter (711mm) D-shaped KitchenSox fabric diffusers. Instead of the metal diffuser’s estimated 500-fpm (2.54m/s) airflow that caused turbulence and disruption of the cooking hood’s capture, the air is gently and evenly dispersed through the fabric into the entire kitchen area at a significantly slower 85-fpm (0.43m/s) rate. Without the previous high velocity airflow and subsequent turbulence, the dual exhaust cooking hood now efficiently performs up to its design standards and captures smoke, grease particulates and cooking odors without overflow.
