Description Casing • Casing made of galvanised steel sheet metal painted with a white RAL 9002 powdered polyester paint • Lateral anti-intrusive grilles painted with aesthetic design offering a protection against external impacts • Unit with attractive design and low height (<2m) for a perfect integration into the surrounding environment Coil • The MXW range is equipped with aluminum microchannel heat exchanger offering reliability and robustness (high mechanical fin resistance) and high corrosion resistance • This technology has proven its value in the automobile sector and is now used for its numerous advantages in the refrigeration sector and air conditioning sectors • These coils offer greater efficiency than traditional coils (copper tubes/aluminum fins). They are significantly lighter and the reduced weight renders them easier to handle. As the coil is brazed in a single operation, the risk of leakage is considerably reduced and the quality inspections are stringent: 100% of the products are tested • Special coating for the coils ensure an improved corrosion resistance for aggressive atmospheres. Standard coils tested for 2000 hours salt spray ASTM G85 - A3 (salt water and acetic acid) EC motors • High reliability electronic switching fan motors (EC) are standard and enable optimised operation of your system • This motor offers a reduction in energy consumption for a given power rating: a detailed comparison of the energy balance may be carried out for each project (please consult us) 2 Kirby MXW EC Condenser Product Overview Advantages Installation Servicing • Optimisation of installation costs: The modular construction allows each module to be connected independently offering autonomous regulation of discharges of several compressorised racks. The user may use one single condenser that reduces the space requirement and installation time. In addition, the reduced refrigerant charge ensures reduced costs • Use of high pressure cleaners for easy coil servicing Maintenance • Easy access to the coil makes maintenance easier. The modules are composed of two coils easily removable for service or replacement • Minimised Footprint: The MXW ranged is optimised to minimise floor space required for installation by the combination of original design and innovative technology: The condenser is indeed built as modules around W-shaped microchannels coils for easy installation in confined spaces • Ideal for use is an urban environment: Various ventilation solutions offered allowing significantly reduce noise level as low as 19 dB(A) at 10m per module (in compliance with Eurovent standards). In addition, the unique sound wall acts as an acoustic enclosure 56 dBA 46 dBA ** 0 kW 83 s r e et 5m Microchannel technology Protection guard Smart construction • Aluminium microchannel heat exchanger with enhanced alloy system • Aesthetic design and easily removable grilles offering protection against external impact • Elevated coils allow unit to sit directly on cement pad. • Copper/aluminium connection with electrolysis insulator 3 Kirby MXW EC Condenser Performance Data R404A FANS MXW223-2V 4 MXW335-3V 6 MXW446-4V 8 MXW558-5V 10 MXW669-6V 12 MXW781-7V 14 MXW893-8V 16 MXW1004-9V 18 MXW1116-10V 20 Q P Q P Q P Q P Q P Q P Q P Q P Q P Q P Max RPM 880 RPM 680 RPM 440 RPM 223.1 8.5 334.7 12.7 446.3 17.0 557.8 21.2 669.4 25.5 781.0 29.7 892.5 34.0 1004.1 38.2 1115.7 42.5 205.2 5.6 307.8 8.4 410.4 11.2 513.0 13.9 615.6 16.7 718.1 19.5 820.7 22.3 923.3 25.1 1025.9 27.9 168.8 2.5 253.2 3.7 337.6 5.0 422.0 6.2 506.4 7.5 590.7 8.7 675.1 9.9 759.5 11.2 843.9 12.4 114.2 0.8 171.2 1.2 228.3 1.7 285.4 2.1 342.5 2.5 399.6 2.9 456.6 3.3 513.7 3.7 570.8 4.2 Max RPM 880 RPM 680 RPM 440 RPM 207.5 8.5 311.3 12.7 415.0 17.0 518.8 21.2 622.5 25.5 726.3 29.7 830.1 34.0 933.8 38.2 1037.6 42.5 190.8 5.6 286.2 8.4 381.6 11.2 477.1 13.9 572.5 16.7 667.9 19.5 763.3 22.3 858.7 25.1 954.1 27.9 157.0 2.5 235.5 3.7 313.9 5.0 392.4 6.2 470.9 7.5 549.4 8.7 627.9 9.9 706.4 11.2 784.8 12.4 106.2 0.8 159.3 1.2 212.3 1.7 265.4 2.1 318.5 2.5 371.6 2.9 424.7 3.3 477.8 3.7 530.8 4.2 R407C 0.87 R134a 0.93 Capacity kW Heat Rejection @10 KTD Power Input kW/hr R134a FANS MXW223-2V 4 MXW335-3V 6 MXW446-4V 8 MXW558-5V 10 MXW669-6V 12 MXW781-7V 14 MXW893-8V 16 MXW1004-9V 18 MXW1116-10V 20 Q P Q P Q P Q P Q P Q P Q P Q P Q P Conversion Factors to other refrigerants R404A 1 4 R410A 1.02 R22 0.96 R407F 0.95 Kirby MXW EC Condenser Multi Circuits Configuration R410A, R407F, R404A, R134a, R22 Example 160kW MT / 40kW LT MT application LT application • 4 modules for MT • 1 module for LT • 8 fans • 2 fans Reduced Footprint • The user may use one single condenser allowing an optimal footprint. • Reduced Installation Cost: (a) Reduced crane time b) Reduced structural frame needs (c) Potentially no sound wall •Flexibility: Each V module can be independently circuited and on different refrigerants An innovative conception designed around 3 main axes… 1.

Selections should be based on keeping the required speed in the range 330-700rpm The same will apply to all refrigerants. The graph can be used to calculate energy use at any speed and the number of fans required to achieve the Heat Rejection required To calculate at a different KTD simply divide by 10 and multiply by the KTD required To calculate at a different refrigerant, use the factors shown in this brochure.
