Aquasystem Expansion Tank Range

aquasystem expansion tankecoHVAC 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.

Restaurant Solves Challenges with KitchenSox

Mrs. Doubtfire Restaurant Solves Cooking Hood Draft Challenges with KitchenSox.

The Issues:
• Performance challenges from kitchen ventilation system.
• Smoke and food odors wafted into portions of the dining area raising complaints from patrons seated at tables near the kitchen.
• Drafts from the existing make-up air HVAC system were drawing smoke and grease and depositing them onto the diffuser, walls, ceilings, and other kitchen surfaces requiring annual maintenance costs.
• Drafts from the air conditioning supply over the food prep area was prematurely cooling prepared hot entrees and employees in other kitchen areas were uncomfortably hot.

The Solution:

DuctSox KitchenSoxDuctSox 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.

The End Result:

A happy customer. Chef Kevin Gin couldn’t be happier. “This is really a common problem (inadequate cooking hood drafting) I think many restaurants suffer from and don’t realize there’s a simple, inexpensive solution,” said Gin. “We once thought replacing the HVAC system would improve our kitchen ventilation challenges, but we now realize it probably wouldn’t have remedied what was actually a ventilation problem that fabric ductwork solved.”

About Acutherm

Acutherm manufactures components for heating and air conditioning systems that make commercial buildings more comfortable, save energy, offer sustainability and can also reduce total installed costs. Our components are called Therma-FuserTM variable air volume (VAV) diffusers. They are used in VAV air conditioning systems which, instead of varying the temperature of the cooling air, vary the amount of the cooling air to maintain even room temperatures.

Aercon – Air Pressure Stabilisers

ecoHVAC now represent Aercon – Air Pressure StabilisersAercon Air Pressure Stabilisers

The guarantee of clean filtered air is essential in many hospital and clean room environments.

The standard technique used to achieve this is to supply treated air into the clean room and maintain a positive differential pressure between this room and adjacent rooms or corridors.

Aercon, a division of the Power Utilities Group, manufacture a range of air pressure stabilisers designed and engineered to facilitate the application of differential air pressure control within hospital operating theatres, aseptic suites, pharmacies, clean room and similar environments.

Aercon, a division of the Power Utilities Group, has over 50 years of experience in the design and manufacture of Air Pressure Control Valves and Air Pressure Stabilisers.

Aercon design and manufacture Air Pressure Control Valves and Air Pressure Stabilisers that are used in in hospitals, operating theatres, clean rooms, for gas fire supression and protected fire routes as well as many other industrial applications. Aercon Air Pressure Control Valves and Air Pressure Stabilisers are used throughout the world.

Type LF – Air Pressure Stabilisers:
Controlling cascade ventilation systems for use in hospital operating thetres, clean rooms and laboratories.
Type W – Air Pressure Control Valves:
For use in humid conditions and the pharmaceutical industry, removeable for easy cleaning.
Type T – Air Pressure Contol Valves:
For controlling pressure in protected escape routes.
Type X – Air Pressure Contol Valves (Heavy Duty):
For specialist industrial and defence applications at pressures of up to 500Pa.

New Aldes Constant Airflow Regulator

aldes constant airflow regulatorAldes launches their new constant airflow regulator MR Modulo.

Constant Airflow Regulators – MR Modulo

Aldes Constant Airflow Regulators range to balance airflows in the ventilation or air conditioning ductworks.

• Multi-airflow (on-site airflow setting)
• Tool-free airflow setting
• Best airflow regulation due to silicone membrane
• Optimum silent operation
• Differential pressure range – 50 to 250 Pa for standard version

Constant Airflow Regulators – MR Mono

Aldes Constant Airflow Regulators range to balance airflows in the ventilation or air conditioning ductworks.

• One airflow (factory set airflow)
• Best airflow regulation due to silicone membrane
• Optimum silent operation
• Differential pressure range – 50 to 250 Pa for standard version – 150 to 600 Pa for high pressure version

The constant airflow regulator balances the airflow in the air conditioning ductworks. It easily fits into a part of the circular ductwork to maintain constant and reliable airflow within a wide range of differential pressure.

Its flexible bulbs inflates and deflates according to the pressure difference between upstream and downstream of the module, thus modifying the free area of the module. This principle guarantees constant airflow regardless of the aeraulic variations in the ductwork.
