An evolution in pump technology
Air conditioning units have changed over the years to meet modern demands. As a result, condensate pumps have evolved too. Marisa May, senior product manager at Aspen Pumps, explains how the latest mini pumps are smaller, quieter and more intelligent, with the 5th
Since the mid-2000s, both wall- mounted and fl oor-standing AC units have been reducing in size, driven by consumers desiring a more
aesthetically pleasing look in habitable rooms. With size at such a premium in modern
developments, smaller AC units are an attractive option for developers.

t is over 100 years since the fi rst air conditioning (AC) unit was designed, so it is no surprise that design has evolved during this period. In recent times, air conditioning has changed to meet both comfort concerns, such as noise, and environmental concerns, such as the F-gas regulations. As a result, AC units today are more intelligent, smaller, quieter, and more effi cient than they have ever been and condensate removal pumps have mirrored these design advances. It was in 2001 that the fi rst ever elbow pump was created. The Aspen Mini Lime broke barriers with its quiet running and easy installation. This was the fi rst pump that could be included inside the trunking that accompanied an AC unit – something not seen before in the HVAC/R industry. Over 20 years later, it is no surprise that the condensate pump design has seen a signifi cant redesign. Smaller, quieter, and more intelligent and effi cient – the pump industry has had to keep up with the latest in consumer demands. This next generation of pumps needed to link the innovations of the last

20 years into one product that could not only be whisper quiet but include intelligent technology that could sit with the ever- changing face of air conditioning units. So, what are the latest developments in mini elbow pump technology?
Rotary diaphragm technology Sound levels are a critical comfort and health and wellbeing issue for end-users, this has driven the design of increasingly quiet AC units and condensate pumps. Following extensive research there are now elbow pumps on the market that break the mould with sound levels as low as 16dBA, the quietest ever, as quiet as the rustling of leaves. This is a signifi cant reduction in sound levels from the last generation of elbow pumps which was 21dBA. To achieve this substantial reduction there has been a huge jump in technology. A signifi cant design development in condensate pump
development has been the replacement of piston technology with innovative rotary technology. Rotary diaphragm elbow
