DE BORTOLI WINERYLocation: Griffith NSW

Application: Bottling Line and Washdown

Collector Size: 100 x Apricus AP-30

Storage Tanks: 2 x 6,000L 2205 Stainless Steel

Commissioned: August 2013

Contractor: Fletcher Plumbing & Co.

De Bortoli Wines were looking to expand their bottling lines to keep up with increased demand. This was seen as an opportunity to increase the efficiency of the production line, and design the new plant to reduce their overall energy usage. This was achieved by utilising wall and ceiling insulation, high efficiency HVAC, condensing boilers, a 230kW photovoltaic solar system and the 200kW Apricus solar thermal plant - the largest solar thermal plant on a winery in Australasia.

De Bortoli’s state of the art solar thermal system utilises 3,000 Apricus evacuated tubes to preheat the condensing boilers and dramatically reduce their gas consumption.

The Apricus evacuated tubes were a perfect fit for this application due to their built in frost protection (-15°C rating without glycol) and high temperature performance. The collectors were mounted on a 37° pitch to maximise solar performance during the winter months.

After commissioning, the system was powered on from 8am with a starting water temperature of 20°C. The system achieved 12,000 litres of storage at a temperature of 71°C by 3.30pm. Ambient temperatures were 10.9°C - 19.9°C.

UFC GYMNASIUMLocation: Sydney, NSW

Application: 20 x Showers20 x Hand basins


Storage Tanks: 2 x 800 L Stainless Steel

Boosting: 3 x 55kW Post Gas Boost

Commissioned: February 2013

The UFC Gym is passionate about providing the newest innovation of fitness and training to Australia. Their passion for innovation goes one step further as the UFC Gym have incorporated both a photovoltaic solar electricity system and an Apricus solar thermal system. The systems ultimately reduce the ongoing electricity and gas running costs of the state of the art facility.

The Apricus solar thermal system utilises 180 evacuated tubes to preheat water to the 165kW gas finishing plant. The system provides all hot water needs for the gym’s showers and hand basins.

By installing an efficient solar pre-heated commercial hot water system, the Gymansium has managed to keep gas consumption to approximately 650MJ per day in winter, and approximately 400MJ per day in summer.

WATERMARC POOLLocation: Greensborough, VIC

Application: Pre-heat facilities indoor poolsDrainback design

Collector Size: 50 x Apricus AP-30’s

Drainback Tank: 1 x 250L Stainless steel

Boosting: Gas finishing plant

Commissioned: September 2012

WaterMarc is the largest aquatic and leisure facility in the northern region of Victoria. It is home to the premier gym and indoor swimming pool in the area with a wide range of fitness classes and training programs.

The 1500 Apricus evacuated tubes are used to pre-heat the indoor pool via a plate heat exchanger. The system is designed in a drainback configuration so while heating, water is pumped through the collectors located on the rooftop, and once heating is no longer required the system drains completely down to the 250L Australian made stainless steel tank.

The Apricus collectors are ideal for utilising drainback configurations due to their high tolerance during periods of stagnation (no water in collector).



CASE STUDY

BYRON BAY SURF CLUBLocation: Byron Bay, NSW

Application: 8 x Bay Shower Block


Storage Tanks: 3 x 315 Mid Element Glass Lined

Model Number: AEC3-315G3-MDC-30

Commissioned: June 2013

Byron Bay is a popular Australian town well known for its beaches, sunshine and commitment to sustainable living. It was only fit that an Apricus evacuated tube solar hot water system was used to capture the abundant sunshine and utilise it to supply hot water to the Byron Bay Surf Life Saving Club’s (SLSC) shower block.

The Byron Bay SLSC’s existing thermosyphon solar hot water system was running solely off the electric booster and needed urgent replacement.

Apricus was contacted to design, supply and install 90 x Evacuated tubes and 945 L storage to the shower block which services up to 200 people per day.

“Since installing the Apricus solar hot water system, our club has enjoyed savings of $500 per month off our electricity bill”- Neil Cameron, President Byron Bay SLSC.



CASE STUDY

NSW POLICE HQLocation: Surry Hills, NSW

Application: 7 Levels, 30 x Showers, Gymnasium


Storage Tanks: 6 x 315 L Stainless Steel Mid Element

Boosting: 6 x 3.6kW Electric

Commissioned: Mid 2013

The headquarters of the NSW Police Force was far from energy efficient prior to installing their new Apricus solar thermal plant in mid 2013.

The seven level premises has 30 showers, 30 basins, three commercial sinks and a Gymnasium which was previously being heated by a single 100 kW electric element inside a 3,000 L low pressure hot water tank. The system was very energy intensive and inefficient as the hot water storage was oversized for the facility.

The 240 Apricus evacuated tubes pre-heat six 315L Australian made stainless steel hot water tanks (1,890 litres in total) to dramatically reduce the amount of electricity that is required to bring water to the desired temperature for the facility.

The Apricus solar thermal system was designed specifically to suit the building’s hot water usage, and is expected to reduce the energy required for heating water by 75%.



CASE STUDY

NEWCASTLE UNIVERSITYLocation: The University of Newcastle Australia

Application: Potable and non-potable water supply to new chemistry building


Storage Tanks: 8 x 315 L Stainless Steel

Boosting: 3 x 32 lpm Natural Gas Boosters

Commissioned: September 2013

The University of Newcastle’s extension to the Medical Sciences Faculty included the construction of a brand new six level building, four levels dedicated to teaching with two levels for plant, research and development.

Two separate loads required hot water throughout the building, the first being potable hot and warm water, and the second non-potable hot water loop.

The building’s annual heating requirement is 18,300 kWh, and the Apricus evacuated tube solar thermal system is designed to contribute 14,521 kWh resulting in approximately 79% reduction in energy consumption for the building’s hot water.

The Apricus AP-30 collectors were chosen due to their high quality and high performance characteristics. Coupled with high quality hot water circulation and gas boosting products, the Apricus solar thermal system is designed to give many years of free hot water from the sun.



CASE STUDY

ARMY BARRACKS POOLLocation: Woodside, SA

Application: Indoor training pool plus accommodation cabins


Drainback Tank: 1 x 450 L

Heat Exchanger: 120 kW Tube in Shell

Boosting: 3 x Bosch 250 MJh Gas Boosters

Commissioned: May 2012

The 1,200 Apricus evacuated tubes mounted at 45° on pitching frames provide heat energy for the 500,000 litre indoor pool used all year round for military training at the Woodside Army Barracks in SA.

The Apricus solar thermal system provides approximately 80% of the energy required annually to keep the pool at a comfortable 27°C. The high output design means gas back up is only required during the winter period when ambient temperatures drop below 10°C.

The system is designed as a drain back system with a 450L drain back tank feeding into a single 120 kW tube in shell heat exchanger.

The drain back configuration was chosen to allow a higher output collector array and avoid stagnation (no load) issues in the summer months. Drain back systems are also common in frost prone areas as it leaves collectors and all associated pipework free from water during shutdown.



CASE STUDY

MERCY HOSPITALLocation: Albury, NSW

Application: 60 x Residents, 2 x Commercial kitchens

Collector Size: 5 x AP30 Collectors

Drainback Tank: 4 x 315 L Stainless steel

Boosting: 3 x 250 MJh Gas Boosters with 2 x 315 L pre-heat tanks

Commissioned: February 2012

An Apricus solar water heating system was chosen to be installed on the Mercy Care Hospital in Albury. The system consists of 150 tubes, and provides solar heated water not only to 60 hospital residents and staff, but also pre heats the hot water supply to the two commercial kitchens located on site, preparing food for the patients.

The Apricus solar hot water system was chosen for its cold weather performance and efficiency. It is estimated that the solar collectors produce 60% of the required annual hot water which reduces gas consumption and extends the life of the commercial gas boosters installed on the building.
