Aspen Pumps has launched the next generation of its popular Silent+ Mini Orange and Silent+ Mini Aqua condensate pumps.
The new additions complete the 5th generation of Aspen’s mini condensate removal pump range, joining the Silent+ Mini White and Silent+ Mini Lime pumps. Now offering a full sweep of ‘Quietly Brilliant’ mini pumps, Aspen gives installers and end-users what it says is the quietest, smartest, easiest to install, most reliable, and versatile mini pumps on the market. Aspen now believes it has a Silent+ mini pump to suit every domestic and commercial mini-split application.
Billed as up to 90% quieter than its competitors, the 5th Gen Silent+ range operates at just 16dB(A), making it quieter than the quietest AC mini-split units, which run at 18dB(A). As the world’s quietest mini pumps, the Silent+ range offers end-users comfort without compromise, so they will be unaware the pumps are even there.
Not only is the new Silent+ range quiet, Aspen says it boasts the smartest mini pumps on the market too, thanks to its proven intelligent 5th Gen pump technology. First introduced in Aspen’s Silent+ Mini White in 2021, it revolutionised managing condensate removal. Featuring built-in AI technology that adapts to flow rates, the pumps only work as hard as they need to and even switch off before they run dry. Unlike pumps that rely on float switches, optical sensors or pressure sensors, Aspen’s 5th Gen pumps’ intelligent technology anticipates and adapts, delivering improved performance and low energy consumption (using 10 times less energy than their predecessors), as well as maximising reliability and extending pump life.
Aspen is so confident that installers can fit and forget the Silent+ range that it is offering a 3-year warranty as standard. With zero maintenance required, each pump features reservoirs that include integrated copper mesh and outlet filter combined with a high-capacity internal bore, which is 50% larger than competitors’, allowing the pumps to handle even more contaminated water with ease. Transparent reservoirs make it easy to check for debris build-up on inspections, and reliability is designed into every component. This results in no callbacks for installers, just hassle-free installation and consistent, dependable performance.
The Silent+ 5th Gen range is available in four distinct models to suit all installation applications. With the Silent+ Mini Orange and Silent+ Mini Aqua suitable for up to 35l/hr; the Silent+ Mini Lime suits up to 40l/hr, and the Silent+ Mini White 45l/h, this covers up to 46kW (I57,000 Btu/h). The range means installers can fit an Aspen Pumps Silent+ mini pump inside a unit, in the cavity above, under the unit, or in trunking. Aspen has covered all domestic and light commercial air conditioning applications where sound levels and reliability are important.
