Case Studies
Virbac Veterinary Supplies

Challenge - Virbac is an international Veterinary Supply Company. For the new facilities they required storage for samples of their products.

Although the 3 rooms reasonably small the internal temperature and humidity conditions varied greatly.

Room 1 - 25ºC plus or minus 2ºC

60% Relative humidity plus or minus 5%

Room 2 - 30ºC plus or minus 2ºC

65% Relative humidity plus or minus 5%

Room 3 - 40ºC plus or minus 2ºC

75% Relative humidity plus or minus 5%

Solution - The design included a 14kW air cooled Aermec Chiller, 3 Grimwood wall mounted heaters, 3 Aermec chilled water fan coil units and 3 Condaire steam humidifiers.

The web based bacnet control system modulates the chilled water for the coils, heating and humidity to maintain the nominated conditions.

Being web based – anyone with the appropriate access can check and modify the system. With the parent company based in France, this certainly has it's advantages.

 
Woronora Cemetary

Challenge - The Crematorium, which has 3 Gas fired cremators had poor ventilation and required the window and doors to be left open.

Solution - Our design required the existing extraction system being replaced with 2 speed high speed fans that could very quickly remove the emissions from the work area when the cremators are opened. Extraction arms were also installed to remove the fire-dust from the workbench.

 
Campbelltown TAFE

Challenge - Campbelltown TAFE Motor Mechanics Trade Workshop had issues with the build up of emissions from the 18 petrol and diesel engines produced during the lesson.

Solution - A combination of Nederman Bench Top extraction arms and spring recovered hose systems. We were able to reduce the levels of CO2 lower than the specified amount.

 
Belle Fleur Chocolates

Challenge - When Yan decided to relocate his factory producing hand-made chocolates and his accompanying retail facilities, he had specific temperature and humidity requirements.

The optimum conditions for chocolate are 18-20ºC and 45-50% relative humidity, otherwise fat blooms appear which is the fat rising to the surface and is white in colour.

The conventional approach using an oversize cooling system and then reheating the supply air would have several disadvantages:

  • Extrememly high energy costs

  • High infrastructure costs and would have to upgrade the electrical supply

  • Standard A/C units would have to be modified to stop “icing up of the indoor coil” due to the low ambient temperature of 18ºC

Solution - Our design combined a Munsters dehumidification system and a standard Actron split ducted system.

SAVINGS  85% reduction in energy costs compared to conventional and 114 tons of CO2.

The construction of the heritage building also caused issues, to install rigid ductwork was not possible due to the exposed beams and being a food facility flat surfaces that allow dust and dirt to build up was unacceptable for health regulations.

Circular fabric ductwork was installed. This prevents dry airborne particles settling on flat surfaces.

 
EnviroLabs

Challenge - This site is a testing laboratory which deals with all forms of soil testing and harmful substances, such as asbestos.

Solution - Within this building we monitor and control the air conditioning, oxygen levels and pressure differentials to prevent contaminants from one lab leaking into another space.

This site is remotely monitored and controlled from our office with on-site audio visual alarms.

 


Testimonials

I would like to praise the tradesmen who installed the air conditioning unit.  They were not only professional in their work, they were very pleasant in manner and left our office as neat if not neater than when they arrived.  We will be very happy to recommend them and your company in the future.
