USA: Tecumseh is to launch a next generation series of air-cooled, low and medium temperature condensing units optimised for HFO-blend refrigerants.
Said to be ideal for walk-in coolers and freezers, the Argus will be unveiled at this month’s AHR Expo in Atlanta and will focus on ½ to 6hp capacities.
The range is said to exceed the DOE’s AWEF requirements by up to 15%, the first hermetic reciprocating compressor condensing units of 1.25hp or less to do so.
In addition to being optimised specifically for HFO-blend refrigerants, the range offers either coated micro-channel condenser coils that can reduce overall refrigerant charge, or conventional tube and fin condenser coils. A swept fan blade assembly option offers extremely quiet operation compared to conventional fan blade and motor combinations meeting the growing requirement in LEED or WELL buildings that require improved indoor environmental quality.
“By applying a combination of reciprocating and scroll compressor technologies, we have developed Tecumseh Argus with serviceability for contractors and building owners in mind,” said Kevin Wilson,Tecumseh’s general manager of condensing units and systems.
Three chassis sizes were developed with a simplified layout, allowing ease of accessibility without removing the top of the enclosure and is equipped with LED lights in the service panel which provide visibility in any situation. A QR code on the inside of the service panel door enables a technician to easily access wiring diagrams, performance data, service part lists and Tecumseh’s technical service team.
The drastically improved assembly of the platform comes from a design that reduces braze joints by 25%, fasteners on average by 25% and product weight on average by 20%.
The Argus offers a variety of customisable options and feature sets. Options can be configured by selecting the pre-configured Silver, Platinum or Gold feature packages or by a combination of options to suit the application requirement. Some of those options include EC fan motor, micro-channel coil, tube and fin coil, air/electric defrost timer, and heated insulated receiver.
