3 COMPANY OVERVIE For more than 20 years, ONDA has been a leading manufacturer of process heat exchangers for the refrigeration and air conditioning markets, partnering with many key OEM customers throughout the world. e offer a full range of shell & tube (DX & Flooded) and brazed-plate heat exchangers, in standard and custom configurations. Our heat exchangers are available with different raw materials and can be used with a variety of fluids. Our systems are compatible with many different refrigerants, including R40A, R34a, R22, R407C, R404A, R507 and others. e can provide multiple certifications, including ASME, P.E.D. and others. All products are manufactured in compliance with ISO 900 standards. 3

4 B SHELL & TUBE CONDENSERS TECHNICAL INFORMATION The Onda B condenser line has been designed for air conditioning and process cooling applications using HFC and HFO refrigerants as primary fluid, the secondary fluid is usually water. Thanks to its high thermal performance tube the B condenser has a compact design reducing the refrigerant charge of 20% - 35% vs traditional condensers with a competitive market price. The capacity range at AHRI 440 standard is from 200 to 5000 kbtu/h, custom models are also available for higher capacity demand Two model range are available at MAP 450 and 650 psig on shell side. The standard configuration is 2 passes with 60 tube length, optional tube length are available to match different operating conditions. B Construction: Shell Tubes Tubesheets Tube Supports Covers ater connections Refrigerant connections Other connections Finish Seamless carbon steel pipe, SA 2.5 shot blasted and cleaned prior to assembly. Copper, high-performance, enhanced design, roll expanded into multiple-grooved tubesheet. Carbon steel plate, precision machined by ONDA Carbon steel plate, machined by ONDA, with close tolerances to minimize vibrations. Cast iron or carbon steel plate, FPT or flanged for corner joint to pipe welding Carbon steel pipe, suitable for ODS copper pipe brazing. ANSI flanges are available. All condensers include additional fittings for safety valves, auxiliary connections, vents and drains. Exterior surfaces are cleaned and painted with a high quality alkydik-phenolic primer, for rust prevention. The refrigerant circuit of each condenser meets the ASME Sect. VIII Div. code requirement and is stamped accordingly. The water and refrigerant circuits are pneumatically tested, to avoid any contamination caused by humidity. ONDA B Condenser Design Suggestions The fouling factor (f.f.) is essential for the correct condenser selection. ONDA uses the following guidelines: - Normal city water f.f. = [ft 2 h F/Btu] - Treated tower water f.f. = [ft 2 h F/Btu] - River water f.f. = [ft 2 h F/Btu] - Glycol solutions < 40% f.f. = [ft 2 h F/Btu] - Glycol solutions > 40% f.f. = [ft 2 h F/Btu] It is recommended that the water velocity inside the tubes is between 3.94 and 9.9 ft/s.
