1 Are these noise cancelling devices needed to make your chiller quiet??

2 Not on this chiller!

3 Some sound barriers should never be broken. Government authorities recommend that exposure to loud noise over 90 db(a) should be limited. At Smardt that wasn t good enough. Our technology breaks through 69.5 db(a) in 1m to make our air cooled chillers the quietest on the market. OSHA Table G-16 Permissible Noise Exposure Duration per day, hours Sound level, dba Whether it s Carnegie Hall, or the Sydney Opera House, owners turn to Smardt when their sound sensitive applications require silence. A Smardt-Powerpax 350kWr air cooled chiller has a sound rating less than 69.5 db(a) at 1m distance under AHRI-575 conditions. At Smardt-Powerpax, we have released our latest line of air cooled chillers up to 1600kWr that are the quietest yet. Combining magnetic bearing oil free compressors, EC VSD condenser fans, low pressure drop micro tube condenser coils and industry beating control sequences, We have a range of air cooled chillers with sound ratings db(a) quieter than leading manufacturers of screw based chillers.

4 Smardt Powerpax air cooled chillers produce a lifetime of energy efficiency An ASHRAE study determined that a vast majority of installed chillers have an excess amount of oil in the cooling system. 3 ½% of oil in the refrigerant charge reduces system efficiencies by 8 %. Excess oil over time degrades the energy efficiency of the system. Oil requires expensive yearly maintenance checks and testing. % Efficiency Loss Percent Oil ASHRAE research study

5 Smardt Powerpax air cooled chillers produce a lifetime of energy efficiency Smardt eliminates the need for oil in all types of chillers by utilizing the Turbocor compressor. A conventional screw air cooled chiller requires a high amount of oil to maintain proper operation. 40 liters oil Typical oil quantity for 1050kw screw air cooled chiller

6 Why Micro Tube? WHY 7mm? More Internal Surface Per Unit Cross Sectional Area Less refrigerant required Higher Efficiency

7 Supersize me Smardt-Powerpax Chillers can deliver up to 1600kW of cooling capacity! Not only is the performance outstanding, there is additional redundancy using 2 separate chiller modules in larger models. The chiller range from kWr includes 10models, each with up to 8 iterations (see next page). With over 80 combinations we will have any of your designed conditions covered for sure!

8 Enjoy the flexibility Even more flexibility for all different kinds of design conditions are offered by Smardt Chiller economizers pushing the cooling efficiency and capacity up to 10% further with the Smardt Chiller ECO range. Additional condenser modules can be added to increase the efficiency and maximum ambient temperature capability. High ambient temperature applications are never an issue for Smardt chillers!

9 Standard isolating valves are critical to serviceability. It can increase a simple repair on an Expansion Valve from 2hrs on a Smardt-Powerpax machine to 2 days if valves are not fitted. Smardt-Powerpax fit an average of 10 isolating valves on every part of the refrigerant circuit as a standard on water and aircooled chillers

11 Footprint reduction and efficiency increase AA series AC series up to -25% A considerably smaller footprint than the previous AA series saves space and facilitates installations. Thanks to smar(d)t Engineering, the footprint is reduced and the efficiency of the new AC series has significantly increased.

13 Our latest innovation - Smardt NanoGuard condenser coating The lotus effect refers to the very high water repellence exhibited by the leaves of the lotus flower. Dirt particles are picked up by water droplets due to a complex micro- and nanoscopic architecture of the surface, which minimizes adhesion. This enables the contact area and the adhesion force between surface and droplet to be significantly reduced resulting in a self-cleaning process. Smardt NanoGuard coating is a hydrophobic nano -polymer coating based on this effect and protecting the condenser coil from corrosive environments. This innovative nanotechnology is not only water and dirt repellant through its self-cleaning function, it has also very high heat transfer capabilities and maintains a long-term efficient heat exchange because of a reduced dirt build-up on the coils. NanoGuard coating is only 5µ thin and resists corrosion, water, and dust; Salt Spray test results achieve over 3,000 hours, and counting.

14 Our latest innovation - Smardt NanoGuard condenser coating SMARDT NANOGuard is a fusion of engineered nano scale particles blended into a single compound that intelligently arrange themselves during application and whilst being baked into a durable finish. Specific particles gather on the fin surface and form an ultra thin homogenous glass like layer of extreme durability. SMARDT NANOGuard has been subjected to a battery of tests: Acidic Humidity to ISO3231 (30 Cycles 0.2 SO2) Constant Humidity to DIN (1000hrs) Salt Spray to ESS ISO 9227 (>3000hrs) UV Resistance to SIO (QUV 300hr) Heat Transfer to DIN 3168!

15 On uncoated fins, water droplets accumulate which can restrict air flow, cause pitting, corrosion and produce water spray. At Smardt-Powerpax, NanoGuard corrosion protection is included in the standard scope of supply! NanoGuard coating prevents the adherence of the water droplets on the fin surface, assisting the fin from accumulating dust and water.

16 Uncoated fin Smardt performed side by side exposure testing of two condenser coils in the harsh environment of a jet airport located near sea. The environment contained salt air and jet fuel wash. After 7 months the NanoGuard coated fin was as clean as the first day, while the uncoated fin showed clear evidence of pitting, corrosion and dust accumulation. Nanoguard Coated fin

18 Dust accumulation test Dust accumulation test was performed on 3 fin types: Plain aluminum epoxy coating Nano coating The test were made according to MIL-STD-810G chapter coils (4 fin types) were inserted into dust chamber that contained 70 gr of red clay dust that was blown in the chamber. Each coil had a draw through fan that circulated the dust through the coils.

23 No Hail Guard needed Thanks to the V coil construction the Smardt-Powerpax Chiller condenser coils are protected from dirt, dust and weather influences like strong hail and direct UV.

24 The most rugged condenser available in the market Smardt-PowerPax air-cooled chillers utilize the most rugged condenser available in the market. The coil frame is built from 3mm thick marine grade aluminium and is fully welded eliminating the potential of any galvanic reaction. Small 7mm diameter copper tubes allow for a high heat density and a simultaneous reduction of refrigerant charge lowering the carbon footprint but improving the heat exchange and increasing the efficiency. The fins are 30% thicker than competitor solutions and designed to handle high air velocities, high ambient temperatures and the most abrasive environments. Additionally, the chiller s base frame is heavy duty hot-dip galvanized and the screws and fixings above the base are stainless steel as standard for optimal corrosion protection. All these advantages result in considerably reduced energy use and maintenance costs, too.

29 Over 10 years ago Smardt-Powerpax led the market by introducing the Turbocor compressor into the air cooled chiller market. Nothing has been the same since. With our latest design, the Smardt air cooled chiller achieves a full load efficiency of over 3.8 COP and 6.5 IPLV under AHRI conditions.

30 We did not stop there. In our new design, we leveraged our oil free expertise to create an integrated free cooling mode. So when it s cold outside, the compressor can be turned off and cooling is achieved using the natural thermosyphoning properties of refrigerant. No extra pumps, coils or fluid coolers are needed. In free cooling mode, only the condenser fans operate reaching an unprecedented efficiency of over 100 COP.
