Since its founding in 1976, EVAPCO, Incorporated has become an industry leader in the engineering and manufacturing of quality heat transfer products around the world. EVAPCO’s mission is to provide first class service and quality products for the Commercial HVAC market.
Specifying Thermal Performance (STD-201RS)
Insist on cooling towers and closed circuit fluid coolers with thermal ratings that are third-party-certified by the Cooling Technology Institute (CTI) by including the following phrase in your next specification: “The cooling towers, inclusive of all accessories and sound reduction options, shall be CTI certified under standard 201RS (STD-201RS).” Refer to the back cover for more details on CTI certification and how it protects consultants, contractors, and end users.
Design Registration of Heat Transfer Coils
In accordance with Australian regulations all manufacturers, importers, and suppliers of certain pressure equipment must not supply such equipment unless it has been Design Registered with an Australian authority having responsibility for plant safety. With regards to Industrial Refrigeration, HVAC, and Industrial Process pressure equipment, Design Registration is required for all evaporative closed circuit fluid coolers and evaporative condensers where the Hazard Level is determined as A, B, C, or D according to AS 4343-2005: Pressure Equipment – Hazard Levels.
The coil design used in EVAPCO’s closed circuit coolers and evaporative condensers has been Design Verified and Registered with an Australian WorkSafe Authority. Protect yourself by insisting to see a manufacturer’s government-issued Certificate of Plant Design Registration by a State, Commonwealth, or Territory authority responsible for plant safety.
Compliant with Australian Standards
Specific legislation exists in Australia and New Zealand regarding the design of cooling towers, closed circuit fluid coolers, and evaporative condensers. Many of the requirements exceed international standards and suppliers must take special precaution to ensure compliance. EVAPCO has taken steps to certify its equipment designs where required so that customers can rest assured that their capital equipment complies with all standards relevant to evaporative cooling equipment:
• AS/NZS 3666.1:2011 “Air-handling and water systems of buildings – Microbial control – Design, installation and commissioning”
• AS 1657-2013 “Fixed platforms, walkways, stairways and ladders – Design, construction and installation”
• AS 1210-2010 “Pressure vessels”
Selection Software & 3D Revit Models
EVAPCO takes pride in ensuring that its equipment is the easiest to specify in the industry by offering comprehensive equipment selection software and 3D Revit models directly to consultants. Tinker with alternative design conditions, optimise selections for energy and freight savings, drag-and-drop BIM-MEPAUS compliant RFA models into 3D project design environments, and much more.

Specifying Sound Performance (ATC-128)
CTI has a standard for the “Measurement of Sound From Water Cooling Towers” which should be considered by a consulting engineer when specifying cooling tower sound on a project. When an engineer simply specifies sound power level rather than sound pressure level at a particular distance and location it becomes difficult to make an apples-to-apples comparison between suppliers. Specifying power alone gives manufacturers an opportunity to apply different assumptions to their data thereby making it difficult for end users to understand the actual sound characteristics of the as-built installation. Ensure that all manufacturers are represented equally and that the sound data accurately reflects the as-built installation by including the following phrase in your next specification: “Cooling tower sound performance shall be provided in pressure dB(A) measured 1.5 metres above the fan discharge during full speed fan operation with water running in accordance with CTI acceptance test code 128 (ATC-128).”
Super Low Sound Fan
When tasked with achieving the lowest sound levels possible, there’s only one choice: the EVAPCO super low sound fan which combines the energy efficiency of an axial fan with the quietness of a centrifugal fan. Made of heavy-duty reinforced polyester, the fan’s ultra-wide chord blades have a forward swept design and rounded edges to minimize the sound caused by flow separation and vortex shedding. The end result is a sound pressure level that’s 9 to 15 dB(A) lower–more than 50% lower–than standard fans (depending on specific unit selection and measurement location). Best of all, the super low sound fan is CTI certified and has zero impact on thermal performance.
Hundreds of EVAPCO models are designed to ship fully or partially assembled in standard shipping containers. This feature reduces the delivered cost of the equipment without sacrificing quality or innovation by reducing the non-value-add costs of transportation & handling. Maximise your kW of heat rejection per dollar by asking your local EVAPCO sales representative for EXW EVAPCO Shanghai pricing on all of your small-to-medium sized projects within Australia and New Zealand.
