Carrier Solutions UK has delivered the fi rst UK installation of the Toshiba Universal Smart X (USX) Series Edge modular heat pump at the Novotel Edinburgh Centre, a
prestigious city-centre hotel. Working in close
Aspen Pumps has launched the next- generation Silent+ Mini Orange and Mini Aqua pumps, completing its 5th Gen mini condensate removal pump range alongside the Mini White and Mini Lime. Designed for domestic and light commercial mini-split systems, the Silent+ series off ers unmatched quietness, operating at 16dB(A). These ‘quietly brilliant’ pumps deliver comfort without compromise, running so silently that users won’t notice them. Built for installer confi dence, the 5th Gen range features intelligent AI-driven technology that adapts to fl ow rates, prevents dry running, and consumes ten times less energy than previous models. Unlike traditional fl oat or pressure sensors, Aspen’s system anticipates demand, enhancing performance and extending pump life. Reliability is core to the design: each pump includes a
transparent reservoir with integrated copper mesh and outlet fi lter, plus a 50% larger internal bore to handle contaminated water. With zero maintenance and a standard 3-year warranty, installers can ‘fi t and forget’ with peace of mind. Available in four models, Mini Orange and Aqua (35l/hr), Mini Lime (40l/hr), and Mini White (45l/hr), the Silent+ range supports installations up to 46kW and fi ts fl exibly inside units, cavities, or trunking.

partnership with installing contractors AlterTherm Group, Carrier Solutions UK provided a high- performance, space-saving HVAC solution designed to integrate seamlessly into the existing hotel infrastructure. Two 150kW Toshiba USX Edge modular air-source heat pumps were installed in July 2024, delivering a combined 300kW of capacity. The installation marked the fi rst deployment of the new-generation USX Edge system in the UK, selected for its compact footprint, modular fl exibility and advanced energy effi ciency. The USX Edge features Toshiba’s enhanced DC twin rotary
compressor technology and an industry-fi rst pulse width modulation (PWM) converter. These innovations reduce energy losses, improve power factor and eliminate harmonic currents. The units operate on lower GWP R32 refrigerant and deliver SEER ratings of up to 4.90 and a CoP of up to 3.62 depending on the model.
Remote monitoring and control via integrated wireless LAN functionality ensures the system can be managed and optimised in real time by both hotel staff and Carrier engineers. An essential benefi t for the hotel was built-in redundancy: each USX unit features independent circuits to maintain operation in the unlikely event of failure, off ering added peace of mind. A key challenge of the project was maintaining hotel
operations throughout. Careful planning of the equipment delivery, crane installation and commissioning process meant disruption was kept to a minimum. The crane lift was completed safely and effi ciently during a late-night window, with surrounding roads temporarily closed to avoid local disruption.
