DAB Pumps says its new Evoplus Lite advanced wet rotor electronic circulator is designed to enhance efficiency, reliability, and comfort, in residential and commercial heating, cooling, and domestic hot water (DHW) systems.
Engineered for ‘plug-and-play’ installation, the quick-connect power supply with superseal technology makes wiring ‘fast and hassle-free’, reducing installation time on site.
The company said: “Ideal for large residential buildings, apartment blocks, offices, schools, hospitals, and commercial properties, the Evoplus Lite delivers adaptive, high-efficiency performance while minimising energy consumption and operating costs. Its sensorless motor control and dedicated 32-bit processor optimise performance in real time, ensuring energy is only used when needed.”
‘Operating seamlessly’ in both heating and cooling systems, the system dynamically adjusts to fluctuating demand, ‘preventing energy waste in heating applications, while maintaining stable operation in air-conditioning systems, even when condensation forms on the pump exterior’. The Evoplus Lite SAN variant, with a bronze pump casing, is designed for domestic hot water recirculation, using a constant-temperature mode to deliver hot water efficiently without the need for thermostatic valves.
Three different control modes allow users to select the most efficient performance curve for their system. In Proportional Differential Pressure mode, the pump automatically adjusts the head to match system demand, ensuring optimal performance at all times. The Constant Differential Pressure mode maintains a stable pressure within the system, improving overall balance and efficiency, while the Constant Curve mode provides a fixed speed option, ‘making it ideal for constant-flow heating and air-conditioning systems where a steady output is required’.
DAB Pumps added: “Built with cast iron hydraulics, an aluminium motor housing, and honed internal surfaces, the Evoplus Lite maximises efficiency while maintaining a robust and durable design. Optional insulation shells help reduce heat loss and condensation, further improving thermal performance in both heating and cooling applications.”
With a maximum flow rate of 12.5 m³/h, a head of 12 metres, and ‘an ultra-quiet operation’ at just 33 dB(A), the Evoplus Lite is particularly suited to noise-sensitive environments such as hospitals, care homes, and residential buildings, DAB Pumps says. Its wide fluid temperature range, from -20 °C to +110 °C, is claimed to make it a versatile choice for a range of HVAC applications, ‘ensuring consistent and reliable performance in varying conditions’.
